DENDROLOGY

Detailed explanation-1: -Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.

Detailed explanation-2: -For photosynthesis to take place the organism must have chlorophyll. Since animal cells do not have chlorophyll photosynthesis does not take place in them.

Detailed explanation-3: -The plants have a cell wall made up of cellulose while the animal cells do not have any cell wall. The plant cell consists of a special cell organelle called plastics which produces chlorophyll for the process of photosynthesis while they are absent in the case of an animal cell.

Detailed explanation-4: -Only cells with chloroplasts-plant cells and algal (protist) cells-can perform photosynthesis. Animal cells and fungal cells do not have chloroplasts and, therefore, cannot photosynthesize. That is why these organisms, as well as the non-photosynthetic protists, rely on other organisms to obtain their energy.

Detailed explanation-5: -1. A plant cell is surrounded by a rigid cell wall. 1. An animal cell does not have a cell wall.
