Question

‘Plants cells have chloroplasts, but no mitochondria.’ Is this statement true or
false? Justify your answer.

Answer 1

Answer:

False. Explanation: The chloroplast organelles are associated with the process of photosynthesis but the mitochondria are associated with the process of cellular respiration. The plant cells possess both of these organelles that is chloroplast and the mitochondria as the photosynthesis process provides the glucose

Answer 2

Answer:

No, the statement is false.

The correct statement - Plants cells have both chloroplasts and mitochondria.

Explanation:

• Plant cells need both organelles, chloroplast and mitochondria. Chloroplast is required to produce food and mitochondria for the respiration.
• Chloroplast - The chlorophyll pigment present in the chloroplast that converts solar energy into chemical energy. It makes food via the process of photosynthesis and releases oxygen molecules. The food is utilised by the plants for the growth.
• Mitochondria - It is the powerhouse of the cell and produces ATP (energy currency of the cell). ATP is used for different processes in the plants such as active transport, minerals release, etc. It utilizes the oxygen produced by the chloroplast for ATP production by electrochemical chain reactions.
• Plants need both the organelles because if chloroplast is absent, plants will not be able to make food and release oxygen. If mitochondria is absent then the entire cell would not be able to carry out its life activities. Because there would be an oxidative phosphorylation and no ATP production. Cells will deplete its energy reserve and die. Hence, both organelles are must for plant cells to survive.
