Detailed explanation-1: -Plant cells, for example, have chloroplasts because they require photosynthesis, but animal cells do not.
Detailed explanation-2: -It is a common perception that animal cells do not have chloroplasts, the organelles that performs photosynthesis. Yet, a small number of sea slugs are able to incorporate carbon from CO2 by performing photosynthesis using sequestered chloroplasts from the macroalgae in their diet.
Detailed explanation-3: -Chloroplasts are exclusively found in plants and photosynthetic unicellular organisms and, hence, animal cells lack chloroplast.
Detailed explanation-4: -Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.
Detailed explanation-5: -The membrane-bound matrix of chloroplasts is stroma and within the stroma, thylakoids are present that are a kind of grana. Hence, Both chloroplast and mitochondria have an interior compartment, the thylakoid membrane is that the wrong statement.
