Plants use the energy of the sun to change water and carbon dioxide into sugars.

These sugars are used by plants • for energy • to make other substances like cellulose and starch. • Starch is stored in seeds and other plant parts as a food source.

This process is called photosynthesis, which means “making things with light”. During photosynthesis, plant leaves take in carbon dioxide from the atmosphere.

Photosynthesis takes place inside capsules in the leaf cells, called CHLOROPLASTS. Using the energy from sunlight, this is combined with water drawn up from the roots to make glucose.

Oxygen is also produced in this chemical reaction and exits the leaves into the surrounding air. Palisade cells and spongy cells are located just below the epidermis and are a plant’s main food-producers.

The tall palisade cells are packed with green chloroplasts, which carry out photosynthesis.Unlike animals, most plants do not need to find food, because they can make it for themselves.Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose.The process of taking these three key ingredients and making them into food is called photosynthesis. Plants capture sunlight using a compound called chlorophyll.Chlorophyll is green, which is why so many plants appear green.During photosynthesis, autotrophic green plants use carbon dioxide and water, along with energy from sunlight (trapping specific wavelengths in chlorophyll) and their chlorophyll to synthesise glucose and oxygen.This process can be illustrated through the following chemical and word equations: During photosynthesis, plants trap light energy with the chlorophyll in their leaves.The rest of the light energy is used in the stroma to combine the hydrogen with the carbon dioxide to make glucose.combine to produce the basic meaning "to put together with the help of light".Many leaf cells contain tiny, lens-shaped organelles called chloroplasts.These can move around the cell towards the direction of sunlight.
