Answer Key

#	Answer
1	Roots anchor the plant and absorb water and minerals from the soil.
2	The leaves make food using sunlight.
3	Plants take in carbon dioxide.
4	Plants release oxygen.
5	Chlorophyll is the green pigment that helps plants absorb sunlight.
6	Plants need water, sunlight, air, nutrients, and space to grow. One correct answer is water.
7	The stem supports the plant and carries water and food between roots and leaves.
8	Photosynthesis.
9	The flower is usually responsible for reproduction.
10	Pollination is the transfer of pollen from the anther to the stigma.
11	Leaves are broad and flat to collect more sunlight for photosynthesis.
12	Roots absorb water and minerals and hold the plant in place, while stems support the plant and transport materials.
13	Plants need sunlight to make food through photosynthesis.
14	Water moves up through the stem to the leaves and other parts of the plant.
15	Transpiration is the loss of water vapor from a plant, mainly through the leaves.
16	Roots and stems help a plant survive on land. Leaves also help by making food.
17	Xylem carries water and minerals from the roots, while phloem carries food made in the leaves to other parts of the plant.
18	It is important because water is needed for photosynthesis, transport, and keeping plant cells firm.
19	A seed is a plant structure that contains an embryo and food supply for a new plant.
20	The seed must germinate, which means it begins to grow under suitable conditions.
21	Seeds usually need water, oxygen, and the right temperature to germinate.
22	Flowers help plants reproduce by producing seeds.
23	Insects help by carrying pollen from one flower to another during pollination.
24	Green plants are important because they make food, produce oxygen, and form the base of many food chains.
25	A plant in a dry environment may have deep roots, thick stems, or leaves that reduce water loss.
