What do different plant parts do?
Plant parts do different things for the plant.
Roots
Roots get water and minerals from the
soil. They help to anchor the plant in the
soil so it does not fall over. Roots also store
extra food for future use.
What do different plant parts do?
Stems
Stems do many things. They support the
plant. They act like the plant's plumbing
system（管道系统）, conducting water
and nutrients（营养） from the roots and
food in the form of glucose（葡萄糖）
from the leaves to other plant parts.
Leaves
Most plants' food is made in their leaves. Leaves
are designed to capture sunlight, which the plant
uses to make food through
a process called photosynthesis.
Flowers
Flowers are the reproductive（生殖的）part
of most plants. Flowers contain pollen and
small eggs called ovules（胚珠）. The ovule
develops into a fruit.
Fruit
Fruit provides a covering for seeds. Fruit
can be fleshy like an apple or hard like
a nut. Seeds Seeds contain new plants.
