2	The flower.
3	Food, or glucose.
4	A stem supports the plant and moves water and food through it.
5	True.
6	The roots.
7	Carbon dioxide.
8	Oxygen.
9	To catch more sunlight for photosynthesis.
10	Photosynthesis.
11	B. Stem
12	Plants need water to make food, stay firm, and carry materials through the plant.
13	A seed is the baby plant before it starts growing; a seedling is a young plant that has begun to grow.
14	Seed, seedling, mature plant.
15	Animals can eat fruits and later drop or pass the seeds elsewhere.

17	The stamen.
18	The ovary.

21	It is responding to light.
22	It may wilt because it does not have enough water to keep its cells firm.
23	Chlorophyll captures sunlight for photosynthesis.
24	Veins carry water and food and help support the leaf.
25	Planting seeds, because beans grow from seeds.
26	The plant would not be able to make food properly, may wilt, and could die.
27	A flower helps with reproduction by making pollen and seeds.
