Question

Plants don't move around, so why do they need energy?

Answer 1

Photosynthesis requires energy, which is provided by sunlight. Carbon dioxide and water are transformed into oxygen (a waste product that is released back into the atmosphere) and glucose throughout this process (the source of energy for the plant). One of the most critical aspects of cultivating houseplants is light. Photosynthesis is required by all plants.

Complete answer:
Why do plants require energy even if they do not move? Plants may generate their own energy. Plants require water and sunlight to produce their own food energy, which is known as: (Photosynthesis).
Because they are living entities, they require energy. Energy is required for a variety of processes in living things, including growth and reproduction. As a result, energy is extremely vital.
Plants do not require transportation from one location to another. Plants' movements are usually at the molecular level, therefore they require significantly less energy than animals. Animals, on the other hand, must migrate from one location to the next in order to get food. Animals, on the other hand, have a much higher energy requirement than plants.
Energy feeds your body's internal functions, repairs, builds, and maintains cells and body tissues, and helps you engage with the physical environment through external activities. Water, the most crucial nutrient in your body, aids in the chemical activities that generate energy from food.
The body requires energy to stay alive, grow, stay warm, and move about. Food and drink are sources of energy. It is derived from the diet's fat, carbohydrate, protein, and alcohol content.
Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to manufacture cellulose and starch, among other things. Cell walls are made up of cellulose. As a food source, starch is kept in seeds and other plant parts.

Note:-
Photosynthesis is the process by which plants produce food. Plants use their leaves to trap light energy during photosynthesis. Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to manufacture cellulose and starch, among other things.
