Plants are organisms.
![Page 3: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/3.jpg)
Plants are the type of organism that can produce their own food, unlike animals. Animals must consume other organisms for the energy they need.
![Page 4: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/4.jpg)
Plants produce food energy in a process called photosynthesis.
![Page 5: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/5.jpg)
Three things are needed by plants in order for photosynthesis to occur.

Plants need small amounts of other substances (vitamins, minerals) to do their best work. Plants get these nutrients from the soil.
![Page 16: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/16.jpg)
What do we call the small amounts of vitamins and minerals that plants get from the soil?

Plants don’t live forever. They grow old and die like every other organism.
![Page 20: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/20.jpg)
Plants would disappear from Earth unless they reproduce. “Reproduce” means to make more of the same.
![Page 21: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/21.jpg)
The way most plants reproduce is by making seeds.
![Page 22: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/22.jpg)
But, before a plant can make a seed, it must get a tiny bit of pollen from a similar plant.
This pollen is magnified many times
![Page 23: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/23.jpg)
Pollen is made in a plant’s flower. Pollen is a fine powder that can blow on the breezes from one plant to another.
![Page 24: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/24.jpg)
But blowing in the wind is not a sure way to get pollen from one plant to another.
![Page 25: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/25.jpg)
Sometimes animals help plants move pollen from plant to plant.
Plants make nectar, a sweet substance, in their flowers.
![Page 26: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/26.jpg)
Pollen sticks to animals as they collect nectar.
Some pollen falls off at the next flower. It just takes a tiny bit of pollen for a plant to make a seed.
![Page 27: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/27.jpg)
Bees are very important in pollination. Without bees there would be a lot less food for people to eat.
![Page 28: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/28.jpg)

After pollination has taken place, the plants can make seeds.
![Page 38: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/38.jpg)
A seed contains a baby plant together with a supply of food to get it started.

After it germinates, the new plant must reach the sun for energy before the
food in the seed runs out.
![Page 40: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/40.jpg)
Some plants produce seeds in ways that make food for animals.
![Page 41: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/41.jpg)
Once again animals can help the plants.
![Page 42: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/42.jpg)
Once again animals can help the plants.
This time, by dispersing seeds so new plants can grow in different areas.
![Page 43: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/43.jpg)
Animals drop some seeds as they move around. Animals help plants by dispersing seeds.
![Page 44: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/44.jpg)
When animals drop seeds it helps the plant reproduce in new places.
![Page 45: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/45.jpg)

![Page 47: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/47.jpg)
What does the word “disperse” mean?
Notes:
To spread around in different places.
![Page 48: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/48.jpg)

A seed can stay dormant (asleep) for years. They usually won’t wake up unless there is water.
![Page 50: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/50.jpg)
The word for a seed “waking up” and beginning to grow is germination.
![Page 51: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/51.jpg)
Germination is also called sprouting.
![Page 52: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/52.jpg)
After the seed germinates, the stem grows up and the roots grow down.
![Page 53: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/53.jpg)
Some plants send down one strong, deep root called a taproot.
![Page 54: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/54.jpg)
Other plants have a system of many softer roots called fibrous roots.
![Page 55: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/55.jpg)
Here are plants with a taproot and a fibrous root side by side.

Every kind of root has tiny root hairs that absorb water for the plant.
![Page 57: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/57.jpg)
Other plants have structures that store a lot of food energy in their roots. These roots are called tubers.
![Page 58: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/58.jpg)
Potatoes, radishes, and carrots are all tubers.
![Page 59: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/59.jpg)
As plants grow above the ground, the stem holds the leaves up in the air.
![Page 60: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/60.jpg)
The stem has tubes that carry water and nutrients from the roots up to the leaves.
![Page 61: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/61.jpg)
Plants must have light for energy. The stem holds leaves up to get more light.
![Page 62: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/62.jpg)
The leaves must have sunlight to make the food that the plant needs to live and grow.
![Page 63: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/63.jpg)
Leaves also give off water vapor as they make food. This water is called transpiration.
![Page 64: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/64.jpg)
Leaves also give off water vapor as they make food. This water is called transpiration. Bigger leaves give away more water.
![Page 65: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/65.jpg)

Sometimes plants must make changes if they are to survive in their ecosystem.
![Page 81: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/81.jpg)
Such changes are called
adaptations.

A plant in the desert must adapt to very low rainfall and a lot of intense sunshine.
![Page 83: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/83.jpg)
Big leaves that give away a lot of water as transpiration wouldn’t help a plant in the desert.

Desert plants have adapted by developing very thin leaves that don’t give away much water.

Cactus needles are leaves that have adapted to a hot dry environment.

It doesn’t rain much in the desert and when it does rain the water doesn’t soak very deep into the soil.

It doesn’t rain much in the desert and when it does rain the water doesn’t soak very deep into the soil.
Deep roots wouldn’t really help a cactus.

Cactus plants have adapted to this.

Cactus plants have shallow roots, close to the surface, that reach as far out as they can.

This is a good adaptation in a place where rain doesn’t soak deep into the ground.

Big leaves would be a good adaptation where it rains a lot and big trees steal most of the sunlight.

Trees in different climates have to adapt to their local conditions.

In a tropical rainforest, near the equator, it is always hot and it rains almost every day. Many plants thrive here.
![Page 97: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/97.jpg)
Trees may adapt here by growing very high to catch more sunlight.
![Page 98: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/98.jpg)
Plants that don’t grow high need to adapt with large leaves to catch more of the limited sunlight that makes it down low.

But they can be very cold in the winter.

Deciduous trees adapt to hot summers and cold by having lots of leaves in summer, dropping them all in autumn, and hibernating all winter.

Deserts

Most desert trees have adapted by growing near the few sources of water.
![Page 107: Ls4 plants](https://reader035.fdocuments.us/reader035/viewer/2022081507/5559d593d8b42a98208b4e02/html5/thumbnails/107.jpg)
Or they have adapted small leaves that don’t lose a lot of water through transpiration.

No trees can adapt to grow in ground that is always frozen.
In the tundra, in the far north and south latitudes, there are no trees.

If an organism can’t adapt to its environment, it won’t survive.
