Ideas Plants are made up of different parts. Each part has a certain job. These parts can also help us to identify plants. There are seven basic requirements that plants need in order to grow properly.

Plant Basic Needs Room to grow Temperature Light Water Carbon dioxide (air) Nutrients Time

Vocabulary Plant Structures – “parts of the plant” –Ex. Leaves, root, stem, flower, seeds, fruit Leaves – help the plant make food through a process known as photosynthesis. Root – help hold the plant in place and take in water and nutrients the plant needs. Stem – supports or holds up the plant. Flower – helps the plant reproduce.

Roots

Roots Functions Most roots grow in soil or water. The roots hold the plant in the ground. A plant uses its roots to get water. The water goes through the roots into the plant. Some roots that we eat are: carrots, beets, turnips, radishes, and sweet potatoes.

Stems

Stem Functions The stem is the part of a plant between the roots and the leaves. The stem holds up the plant. The stem also carries water and food through the stem to the plant. Some stems that we eat are: celery, broccoli, asparagus, white potatoes, and sugar cane.

Leaves

Leaf Functions A leaf grows on the stem or branch of a plant. A green plant makes food in its leaves through a process known as photosynthesis. The leaf has tiny holes that let water vapor and air pass through. The leaves need sunlight, air, and water to make the food for the plant. Some leaves that we eat are: lettuce, brussel sprouts, spinach, and parsley.

Fruit and Seeds

Fruit and Seed Functions Seeds are made from flowers. Many plants grow from seeds. Fruits hold seeds. Some fruits that we eat are: tomatoes, oranges, pears, watermelon, and strawberries

Structures of a Flower

Flower Functions Flowers grow on the stem of plants. Flowers make seeds. Many plants grow from seeds. Flowers make fruits. Fruits hold the seeds of the plant.
