Detailed explanation-1: -Answer: Chloroplasts help in the synthesis of food by the process of photosynthesis.
Detailed explanation-2: -What function in plant cells is comparable to an animal eating food? Chloroplasts absorbing solar energy for cellular activities.
Detailed explanation-3: -Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Detailed explanation-4: -Just as photosynthesis occurs in organelles called chloroplasts, cellular respiration takes place in organelles called mitochondria. Remember that mitochondria are in both plant cells and animal cells, so both kinds of cells release energy through cellular respiration.
Detailed explanation-5: -Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
