Cells and Tissues in Leaves
Plants make their own food in its leaves.
Leaves are organs made of cells and tissues.
The epidermis, top part of the leaf, is the layer of flat cells that protects the plant from the outside, like your skin.
Tiny openings at the bottom of the leaf allow air to pass in and out of the inner tissue.
Vessel tissues carry food and water through a plant.

PhotosynthesisPhotosynthesis is the process that plants use to make sugar for food.
Plant cells use cellular respiration which means they use oxygen with food for growth, repairs and reproduction.
Plants need sunlight, water, and carbon dioxide for photosynthesis. Sunlight gives the cell energy for photosynthesis. It gets water from its root hairs and enters the chloroplasts. Carbon dioxide comes from the atmosphere and enters through the leaves.
The process of photosynthesis uses water and carbon dioxide to make sugar, and also produce oxygen. Plants also store sugar, which turn into starches.
Sugar is also used in plants to form cellulose, a chemical that makes up a plants cell wall.
Plants have more sugar in the daytime than night time because the suns energy reaches the chloroplasts to it can make more sugar, at night there is no sun so plants have to use the stored sugar and cannot produce more sugar.

TextQuest
1. What is the purpose of the tiny opening on the bottom of the leaves?
2. Describe the process of photosynthesis.
3. Why do plants go through photosynthesis?
