Question Answer
Name the process for how plants make their own food. -photosynthesis
Name the structure where plants make their own food. -chloroplasts
What is the pigment in plants? -chlorophyll
Name the 5 structures of a plant. 1)the cuticle 2)the cell wall 3)the root 4) the stem 5)the leaf
What is the cuticle? -the waxy layer on stems and leaves (or any other part of the plant that is exposed to air) that protects the plant from drying out.
What is the cell wall? -the hard, outside layer made of carbohydrates and proteins that protect and support the cell
What is the purpose of the roots? -for support, to transport, and for storage
What is the purpose of the stem? -for support, to transport, and for storage
What is the purpose of the leaf? -makes food
What are the 2 phases of the life cycle of reproduction in plants? 1)sporophyte 2)gametophyte
Explain/Describe spores. -they are produced in the sporophyte stage
-they are tiny reproductive cells
-if they land in a suitable environment, they will grow to form a new plant
Explain/Describe sex cells. -they are produced in the gametophyte stage
-they are egg and sperm
-they must fertilize each other in order for a new plant to form
Describe nonvascular plants. -they are plants without "pipes" used for the transport of water and nutrients
What do nonvascular plants rely on? -they rely on osmosis and diffusion t transport water and nutrients around the structure
Where are nonvascular plants usually found? -they are found in wet environments
Give 2 examples of nonvascular plants. -mosses and liverworts
Describe vascular plants (no seeds). -they do not produce seeds
-they are plants with "pipes" used for the transport of water and nutrients
Give 3 examples of vascular plants (no seeds). -ferns, horsetails, club mosses
Describe vascular plants (seeds). -they are plants with "pipes" used for the transport of water and nutrients
-they do produce seeds
Name and describe the 2 types of vascular plants with seeds. -gymnosperms (non-flowering)
-angiosperms (flowering- assists in reproduction)
