This document summarizes the key parts and functions of plants. It explains that plants have roots that absorb water and nutrients from the soil, stems that transport resources between the roots and leaves, and leaves that contain chlorophyll and perform photosynthesis using water, carbon dioxide, and sunlight to produce food for the plant. The document also provides a high-level overview of the photosynthesis process where water and minerals are absorbed by the roots and transported to the leaves, and carbon dioxide is absorbed to produce glucose and oxygen through the action of chloroplasts and chlorophyll.
4. Only have small flowers their seeds developed
in cones.
5. They have roots and strog stems and grow
under the ground. They have large leaves.
They produces spores inside sori.
6. They have very simple stems and leaves. They
produce spores.
7. Hold the plant in the ground. Absorb water
and minerals from the ground through the root
hair.
8. Holds up the other parts of the plant, transport
materials to and from leaves. Nutrients travel
through the stem to the leaves for
photosyntesis.
9. Contain chlorophyll, a green substance which
is neccesary for photosyntesis. Have two
groups: petiole an blade. Veins support the
leaf, undeside the blade are tiny holes, called
stomata. The gas take place through stomata.
10. Plants make their own food whit a process called
photosyntesis:
Roots absorb water and minerals from the soil.
Xylem cells transport this mixture of water and minerals,
called raw sap, through the stem to the leaves.
Leaves absorb carbon dioxide through the stomata. In the
chloplasts, chlophyll collects solar energy to transform
water, minerals and carbon dioxide into glucose and
oxigen.
Phloem cells carry the glucose, the plants food through
the stem to all parts of the plant.
11. Plants consume oxigen and produce it too.
They produce more oxigen for photosyntesis
during a day. At night, when photosyntesis
stop, plants relase carbon dioxide.
