Explain the mechanism of photosynthesis.
And explain the process of Nutrition in Amoeba with diagrammatic elaboration.
Answers
Answer:
Solution
The mode of nutrition in Amoeba is called Holozoic nutrition.
The nutrition in amoeba takes place in the following steps:
1. Ingestion: The process of ingestion is nothing but intake of food into the body. Amoeba is unicellular and hence it does not have mouth, Amoeba takes the food into the body by forming structures called pseudopodia around the food particle. This pseudopodia forms a vacuole around the food particle called food vacuole and the vacuole is taken inside the cell.
2. Digestion: The food particle inside the vacuole is broken down into soluble particles by digestive enzymes inside the vacuoles.
3. Absorption: The broken food particles is absorbed into the cytoplasm of amoeba by diffusion. The food particles which are unabsorbed are left inside the vacuole.
4. Assimilation: The absorbed food is converted into energy in this step.
5. Egestion: The undigested food in the food vacuole is thrown out from the cell.
Answer:
Photosynthesis is a method of transforming light energy into chemical energy by phototrophs, which is later used to fuel cell functions. Chemical energy is stored in the form of sugars, which are generated from carbon dioxide and water.
