1.- WHAT ARE LIVING THIGNS LIKE? CELLS


5


We can recognise living things because they share the following characteristics:

They are born. All living things come from other living things.

They eat. All living things need food. They grow. All living things increase in size during their

life time. They react. Living things can perceive what is going on

around them. They reproduce. Living things can create offspring

similar to themselves. They die.

There are three basic life processes:

Nutrition. Living things eat food, which contains nutrients. Nutrients are substances that living things use to grow or provide energy.

Sensitivity. Living things perceive what is happening around them and respond to what they perceive.

Reproduction. New living things replace the ones that die.

ACTIVITIES:

1.- What six characteristics do all living things have in common? Write:

Living things ……………………….

________________________________________________________

2.- Write five non-living things.

3.- Complete the following sentences with: Reproduction, Nutrition or Sensitivity.

a) ________________ involves ingesting food substances.


6


b) ________________ enables living things to perceive what is happening around them.

c) _______________ enables living things to create offspring.

4.- Draw a picture for each life process.

What is a cell?

Living things are made up of tiny units called cells.Cells are the smallest living units in a living thing. Cells are living things. This means that they carry out the life processes of nutrition, reproduction and sensitivity.

Some living things are made up of a single cell. They are unicellular.

For example: The amoeba.


7


Other living things are made up of many cells. They are multicellular.

For example: You.

ONE NAME, MANY TYPES

There are many types of cells. You can distinguish between plant cells and animal cells. Plant cells have wall; animal cells do not.

9


There are many types of cells. Humans have hundreds of types of cells. Different types of cells have different tasks or functions.


10


Parts of a cell

Cells have three parts:o The membrane is the covering around the cell.o The nucleus is the part which controls the function of the

cell.o Cytoplasm is the space between the nucleus and the

membrane.o Plant cells have also a wall around the membrane.

ACTIVITIES:

1.- What are cells? Put in order the words in the box.

________________________________________________________

2.- Write TRUE or FALSE.

a) Cells aren’t living things.b) Cells can reproduce.c) There are living things with only one cell.d) There are living things with many cells.e) All the cells are the same. f) All the cells do the same task.g) Animal cells and plant cells are different.

3.- What’s the name of a living thing made up of a single cell?

4.- What’s the name of a living thing made up of many cells? Write three examples.


11

are – smallest – units – a – thing. – Cells – the - living – in - living


5.- What is the main difference between an animal cell and a plant cell?

6.- Draw an animal cell and label its parts.

7.- Draw a plant cell and label its parts.

2.- THE ORGANISATION OF LIVING THINGS

Multicellular living things have the following structure. Cells form tissues. Tissues are made up of the same type of

cells, which work together. Tissues form organs. Organs are made up of different types

of tissues, which work together. Organs form systems. Systems are made up of different

organs, which work together. An organism is a complete living thing. Different systems

work together in an organism. All living things are organism.

You can find many different tissues in an organ. Look at this stomach:


13


ACTIVITIES:1.- Put the words in order from the simple structure to the most complex structure.

2.- Write more sentences. Change the underlined words.

Tissues, such as muscle tissue, are made up of cells which work together._____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

3.- Complete this text:

All living things are made up of __________. Cells group together to form __________. Tissues form __________. Organs form __________. An ____________ is a complete living thing.

4.- Draw:

3.- KINGDOMS

Living things are classified into five groups called kingdoms.The main kingdoms are the animal kingdom, the plant kingdom and the fungi kingdom.

3.1 The animal kingdom.o Animals are multicellular.o Animals eat other living things.o Animals can move from one

place o another. o Animals have a nervous system

and sense organs.o Animals react to stimuli.

3.2 The plant kingdom.o Plants are multicellular.

o Plants use sunlight and substances from the soil and air (carbon dioxide) to make their own food.

o Plants cannot move from one place to another. They have roots in the ground.

o Plants don’t have a nervous system or sense organs.

3.3 The fungi kingdom.o Most fungi are multicellular. A few are unicellular.o Fungi depend on other organisms for food.o Fungi are fixed to something. They can not move.

Some examples of fungi are:

2. Read carefully: WHAT TYPE OF LIVNG THINGS ARE FUNGI?


17


Fungi are living things. They are born, grow, reproduce, and die, but they are not plants or animals.

Fungi are not plants because they cannot make their own food. They absorb nutrients from the remains of other living things. They are not animals because they don’t have sense organs and they cannot move.

Some fungi, such as yeast, are tiny to see. Others’ such as moulds, are also tiny, but you can see them all together.

Some fungi are in the ground. In autumn, they become mushrooms and grow above the ground. There are many edible mushrooms.


18


MATCH.

Fungi are they don’t have sense organs.

Fungi aren’t plants because born, grow, reproduce and die.

Fungi aren’t animals because they cannot make their own food.

3.- How to observe and describe fungus.

PROCETURETo describe a living thing, first observe it carefully.Then talk about its size, colour and shape.For example to describe a mushroom, answer these questions:
