“I don’t know anything.” is not an acceptable answer.Use complete sentences.
After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond.

characteristics 1. multicellular
Plantae
2. eukaryotes 3. autotrophes
Living on land In order to live on land, plants must be able to:1. Obtain water 2. Retain water 3. Reproduce4. Support weight
non-vascular - no roots, exchange of water via active and passive transport5. Transport materials
Example: mossvascular - internal system of tube-like structures that transport water,
nutrients, and food inside the plantExample: trees, daisies, roses
Two type of tubes
phloem - transports food (sugar) from leaves to stems and roots
xylem - transports water and nutrients from roots to stems and leaves
reproduction Seeds - for dispersalExamples: monocotyledons - corn and grass
dicotyledons - peas and beansSeedless - spores for dispersal
Example: fern

Plantae
leaves - contain chloroplasts, which capture sun’s energy to make food (photosynthesis)
Leaf parts
cuticle - waxy water proof coat on the top side of the leaf - aids in directing water toward the roots
stoma
Leaves’ job Make food from carbon dioxide, water, and sunlight.
- little valve-like structures on the surface of the leaf which allow CO2 to enter and water and oxygen to exit the plant
Stem’s job 1. Supports the plant
2. Carries nutrients, water, and food between the leaves and roots
FYI: A majority of the human population relies on plants as their main food source.
Examples: herbaceous - soft, flexible, and green (daffodil) woody - hard and covered with bark (oak tree)
Root’s job 1. Anchor the plant to the ground2. Absorb water and nutrients
Examples: tap root (dandelions) fibrous roots (tomato plant)
Impact Without plants, our ecosystem could not replenish the oxygen that we need to survive!
