LIFE SCIENCE

Detailed explanation-1: -For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not.

Detailed explanation-2: -The process by which plants and certain organisms convert light energy(sunlight), water, and carbon dioxide into food(sugar). 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: -However, not all parts of a plant structure are suitable to do this, so not all types of plant cells contain chloroplasts. The plant cells that make up the roots and/or tubers typically do not contain chloroplasts since it would be useless to have them.
