Plants Study Guide
1. Plants are multicellular, which means they have 2 or more
cells. They are also eukaryotic which means they have a
nucleus. They are also autotrophs (producers) which means
they make their own food.
2. If plants have a system of tubes for transportation they are
called vascular plants. If they lack these tubes they are called
nonvascular plants.
3. Vascular tissue includes phloem which transports food and
xylem which transports water and minerals.
4. Plants have two stages of their life cycle –the sporophyte and
gametophyte. The sporophyte stage is when they produce
spores. The gametophyte stage is when they produce gametes
(sex cells/sperm and egg).
5. List 3 the methods of seed dispersal:
a. wind
b. water
c. other organisms
6. What are cotyledons? seed leaves
7. What type of vascular plant produces “naked seeds”?
gymnosperms
8. What type of vascular plant produces fruit? angiosperms
9. Monocots have one cotyledon and dicots have two cotyledons.
10.
Parts of a Flower:
11. Define sepals: small leaf-like part of the flower that
protects the developing petals
12.
Why is the stigma sticky? pollen attaches to the stigma
13. After fertilization, what happens to the ovary in the
diagram? (pg. 278) It develops into a fruit.
14. Germination is when the plant is pushing out of the seed.
This occurs when the seed absorbs water.
15. What is the difference between the stomata and the
cuticle? stomata—small opening on the underside of leaves
where gases are exchanged; cuticle—waxy layer on leaves
that helps retain water
16. What are root hairs used for? increase surface area of roots
to help absorb more water and minerals
17. Define dormancy period of time when growth of a plant
stops
18. Define tropism plants growth response towards or away
from a stimulus
19.
This is an ancestor to plants algae.
