PLANT PARTSBasic parts of most all plants are roots, stems, leaves, flowers, fruits, and seeds. We will study three of these here..the roots, stems and leaves. We have all seen the pretty flowers and the fruits and helped our Meowmies plant the seeds at times.
The roots help provide support by anchoring the plant and absorbing water and nutrients needed for growth. They can also store sugars and carbohydrates the plant uses to carry out other functions.
Stems carry water and nutrients taken up by the roots to the leaves, and then the food produced by the leaves moves to other parts of the plant. Stems also provide support for the plant allowing the leaves to reach the sunlight they need to produce food.
Leaves are the food making factories of green plants. Leaves come in many different shapes and sizes. Leaves are made to catch light and have openings to allow water and air to come and go. Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar). This energy rich sugar is the source of food used by most plants.
A green plant helped make the oxygen you are breathing today.
Plants need several things in order to flourish. They need room to grow, the proper temperature, the correct amount of light, water, air and nutrients, such as fertilizer.
