Did you know scientists have found and named over 260,000 species/plants on Earth, but do you know what it takes to make them grow?
Green plants use photosynthesis to grow and make their own food. Fungi and some higher plants can't make their own food. Want to know why?

      Green plants use photosynthesis (sun's energy). Fungi depend on other living things for their food. Fungi like plants are called saprophytes. Leaves are the main source used to make photosynthesis. Photosynthesis is a process, when the plant's leaves absorb the sunlight to make energy for their food. The food is made from the roots absorbing water, the stem collecting carbon dioxide, and the sun's energy for carbohydrates and oxygen. After carbohydrates are made they are used to make new cells, stored in a plant as sugars and starch, or into other substances, such as pigments or fats. Respiration takes place 24/7, even at night. Using some of the  carbohydrates stored from photosynthesis are burned by oxygen to produce energy. This makes a plant give off carbon dioxide and water. Once they give off carbon dioxide and water they make more food and oxygen. Other pigments such as, carotene and xanthophyll are hidden underneath chlorophyll in plants' leaves. These pigments are actually orange and yellow. That is why in autumn leaves change color. Plants are important because during the photosynthesis process it makes oxygen, and we need oxygen.
