Why chloroplast need mitochondria and mitochondria need chloroplasts?

Answer 1

because chloroplasts produce energy in the daylight and mitochondria produce energy day and night

Answer 2

Chloroplasts need mitochondria because they provide energy in the form of ATP for chloroplast functions, such as photosynthesis. Similarly, mitochondria need chloroplasts because they rely on carbon compounds produced by photosynthesis in chloroplasts for their energy production through cellular respiration. This mutual interdependence ensures the efficient functioning of both organelles in plant cells.
