Question

Green plants are called as ___ since they synthesize their own food.

Answer 1

Hint: Green plants include green algae and land plants, including liverworts, mosses, ferns, and other non-seed plants, and seed plants. Plants are producers because they can produce their food. This occurs in the presence of sunlight. This process is called photosynthesis.

Complete answer:
Autotrophs are defined as an organism that manufactures its own food from inorganic substances, such as carbon dioxide and ammonia. Green plants are called autotrophs since they are able to synthesize their own food. In photosynthesis, solar energy is captured by the pigment, Chlorophyll.
During photosynthesis, plants consume carbon dioxide and release oxygen gas. The green plants have chlorophyll in their leaves. The food synthesized by the plants is stored in the form of starch. Photoautotrophs are related to light. They take up carbon dioxide and emit oxygen which is consumed by us.
Plants are the only organisms that can prepare food for themselves by photosynthesis. The raw materials are present in their surroundings. The mode of nutrition in which organisms make food themselves from simple substances is known as autotrophic nutrition.

Additional information:
1. The various steps involved in the process of photosynthesis are given below:
2. Absorption of light energy through the sun by chlorophyll present in leaves.
3. Conversion of light energy chemical energy.
4. In this process, the water molecule splits into hydrogen and oxygen.
5. Carbon dioxide is reduced into carbohydrates like glucose.

Note: Autotrophs are those organisms that can prepare their own food in the presence of sunlight. The process is known as photosynthesis. Since green plants make their own food in the presence of sunlight, photosynthesis, they are called autotrophs.
