Why do all plant cells contain chloroplasts?
A. Chloroplasts are necessary for cellular respiration.
B. Chloroplasts are necessary for photosynthesis.
C. Chloroplasts are necessary for reproduction.
D. Chloroplasts are necessary for growth.
B. Chloroplasts are necessary for photosynthesis.
Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert light energy into chemical energy in the form of glucose. This is a crucial process for plant survival and growth, as it provides them with the energy they need to carry out cellular functions. Therefore, all plant cells contain chloroplasts to enable them to generate their own food through photosynthesis.
