Green plants use a pigment called chlorophyll to collect sunlight and produce excited electrons that then drive a complex of other proteins to manufacture glucose.
Other organisms (mostly microscopic) use other pigments of a variety of different colors in the same way.
Carbon dioxide and water
Plants use carbon dioxide and water to make glucose molecules through the process of photosynthesis. Carbon dioxide is taken in from the atmosphere through tiny pores in the leaves called stomata, and water is absorbed from the soil through the plant's roots. These compounds are converted into glucose with the help of sunlight and chlorophyll.
Oxygen from carbon dioxide, and hydrogen from water, enter through the leaves and roots, and are used to make glucose
They use it to make reactions with CO2 molecules to form the carbohydrates.
It would be more accurate to say that glucose molecules are converted to starch for storage. To make starch, the glucose units join together in a long chain, like beads on a necklace. In order to form the links, each glucose must drop a few atoms so the whole glucose is not present in the starch.
Plants use light energy to make glucose.
The process in which the sun is used to make energy rich molecules is called Photosynthesis. This process uses carbon dioxide, water and energy collected from the sun, to produce glucose molecules and oxygen gas. This process happens in plants and is the plant's main source of energy.
Carbons in photosynthesis are used to produce organic molecules, such as glucose, which serve as energy sources for plants. During photosynthesis, carbon dioxide is converted into carbohydrates using the energy from sunlight. These carbohydrate molecules are essential for the growth and development of plants.
Plants need water to make glucose. Glucose is a sugary substance that plants make. Glucose is the food that plants need to live. So yes, plants do need water.

Plants produce glucose through photosynthesis, a process where they use sunlight, water, and carbon dioxide to create glucose and oxygen. Animals obtain glucose by consuming plants, or by consuming other animals that have consumed plants. Glucose is then used as a source of energy in both plants and animals through the process of cellular respiration.
Plants use glucose monomers to make cellulose, which is a structural polysaccharide found in their cell walls. Glucose molecules are linked together in chains to form cellulose polymers through dehydration synthesis reactions.
