Answer Key

#	Answer
1	A plant is a living thing that usually grows in soil and makes its own food using sunlight.
2	Root.
3	The roots.
4	The stem.
5	The leaves.
6	Plants use sunlight to make food.
7	Carbon dioxide.
8	Oxygen.
9	Roots hold the plant in place and absorb water and minerals.
10	Photosynthesis is the process plants use to make their own food using sunlight, water, and carbon dioxide.
11	The stem supports the plant and moves water and nutrients through it.
12	A large surface area helps leaves catch more sunlight.
13	Water.
14	Sunlight.
15	The flower helps make seeds.
16	Pollination is the transfer of pollen from one part of a flower to another, usually to help make seeds.
17	By insects, wind, or animals.
18	Bright flowers help attract pollinators like bees and butterflies.
19	Seeds grow into new plants.
20	Seeds need water, air, and the right temperature to begin germination.
21	Germination is when a seed begins to grow into a new plant.
22	Plants release oxygen, which living things need to breathe.
23	Plants are important because they are part of ecosystems and help provide oxygen, food, and habitats.
24	A tree is usually a larger woody plant, while a flower is the bloom of a plant that helps with reproduction.
25	It can wilt, grow poorly, or die.
26	Roots absorb water, and leaves use that water along with sunlight and carbon dioxide to make food.
27	Soil helps hold plants in place and provides water and nutrients.
28	It may not make enough food and could become weak or die.
29	Plants provide food, oxygen, materials, and shade.
30	A seed gets water, air, and warmth and begins germination. The root grows first, then the stem and leaves grow as the plant starts making its own food.
