How Seeds Become New Plants KEY
1. Parts of a Seed (match)
a. Embryo
b. Cotyledon
c. Seed coat
-keeps the seed from drying out
- young plant that develops from the fertilized egg
-a seed leaf that sometimes stores food
2. What do seeds need to develop into a new plant? Light, water, nutrients (stored food) and favorable conditions
3. Can seeds begin to grow any place they land? NO Why, or why not? It depends on the conditions.

Paraphrase germination: sprouting of an young plant out of a seed
ROOTS
6. List the 3 main functions of roots: 1)anchor the plant to the groud 2)absorb water and minerals 3)sometimes
store food
7. Label the root systems below taproot or fibrous roots as well as the root hairs.
Fibrous Roots
Tap root
8. Label the root structure with the appropriate part.
Pholem moves food to the roots and other parts of a plant.
Root Cap protects the root from injury during growth.
Xylem moves water and minerals to the stems and leaves.
Root hairs increase the amount of water and minerals absorbed by the root.
Root hairs
9. The cambium layer of the cell layer that produces new phloem and xylem.
STEMS
10. List the 3 main functions of stems: 1)carry substances between leaves & the roots 2)support 3)Stores food
11. True or False? Herbaceous stems are hard and rigid and have an outer layer called bark. False
12. What layers make up the tree’s annual rings?xylem
13. One year’s growth of a tree is represented by one pair of light and dark rings in the tree’s stem.
LEAVES
14. What role do leaves play in a plant? to capture the sund energy (light) and carry out photosynthesis and cellular
respiration.
15. Cuticle C
a. Widely spaced cells allow carbon dioxide and oxygen to pass in and out of the leaf.
16. XylemB
b. Carries water from the roots to the leaves
17. PhloemE
c. Waxy, waterproof coating that overs a leaf’s surface
18. Stomata F
d. Contain the most chloroplasts
19. Lower leaf cells A
e. Carries food made in the leaves to the rest of the plant
20. Upper leaf cells D
f. Tiny pores that open & close to let carbon dioxide in & water vapor & oxygen out.
21. The process by which water evaporates from a plant’s leaves is called transpiration.
22. What is the job of the stoma? To regulate water loss-they close to keep the plant from losing too much water.
