|
Chloroplasts manufacture food; mitochondria break down the food and convert it into energy.
|
|
|
Chloroplasts package nutrients; mitochondria deliver the nutrients to other parts of the cell.
|
|
|
Chloroplasts absorb water from the surrounding tissue; mitochondria store water.
|
|
|
Chloroplasts direct the functions of the cell; mitochondria deliver messages to all parts of the cell.

Detailed explanation-1: -In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.
Detailed explanation-2: -Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.
Detailed explanation-3: -Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
Detailed explanation-4: -Chloroplasts and mitochondria are required by plant cells because they carry out photosynthesis and cell respiration respectively. While mitochondria, the heart of the cell, creates ATP during respiration, the chloroplast transforms light energy into chemical energy during photosynthesis.
Detailed explanation-5: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
