DENDROLOGY

Detailed explanation-1: -Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.

Detailed explanation-2: -It acts as their food and provides them energy. Plants need to synthesise their own food because unlike other living organisms, plants can not move and cannot hunt. But, for their sustenance they need food, therefore they have to make their own food.

Detailed explanation-3: -Green plants are the only living organisms that produce their own food. Light provides the energy to create a chemical reaction within specialized cells, called chloroplasts, in the leaves. Chlorophyll present in the chloroplasts captures light energy and uses it to produce simple sugars from carbon dioxide and water.

Detailed explanation-4: -All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Detailed explanation-5: -Most plants prepare food by the process of photosynthesis. The process by which leaves prepare food using water and minerals from the soil and carbon dioxide from the air in the presence of sunlight and chlorophyll is called photosynthesis.
