Plants
There are two major categories of plant
Vascular plants
Vascular plants
Nonvascular plants
Nonvascular plants can only move water and nutrients from one cell to the next.
moss algae
Vascular plantshave a system of tubes or vessels that carry
water and nutrients around then plant.
This tube system allows vascular plants to grow much larger.
Most plants we see are vascular plants.
Animals have one system of tubes to carry nutrients to all the cells.
This is called the
circulatory system.
Vascular plants have two separate systems of tubes.
Xylem are the tubes that carry water up the stem from the roots to the leaves.
Phloem carries food made in the leaves to all parts of the plant.
Xylem (zie lem) are the tubes that carry water up the stem from the roots to the leaves.
Phloem (flo em) carries the food made in the leaves to all parts of the plant.
Plants are producers. They make food.Only plants can make food.
Plants make food in their leaves.
A green material in the leaves called
chlorophyll (clor ah fil)
turns light energy from the sun into
chemical energy (sugar).
Plants can’t grow without this energy.
Animals can’t live without this energy.
Plants must have three things in order to make food.

The process of turning sunlight energy into chemical energy (food) by plants is called
The process of turning sunlight energy into chemical energy (food) by plants is called
photosynthesis(foh toh sin theh sis)
Photosynthesis works like this
+ H2O + CO2 Light (energy) (water) (carbon dioxide)
=
C6H12O6 + O2(sugar) (oxygen)
H2O and CO2are pressed together into a sugar molecule by the sun’s energy like a spring.
A spare oxygen molecule is released in the process.

When plants make food they release oxygen as a waste gas.
CO2 (carbon dioxide)is a gas that makes up about 1% of earth’s atmosphere.
Animals release CO2 into the air as a waste product when they breathe.
Plants take in CO2 and use it as they make sugar (chemical energy).
Plants release oxygen as a waste product as they make food.
Plants can’t live without CO2 and must release oxygen.
Animals can’t live without oxygen and must release CO2.
This is a very important
balance for life on Earth.
