Why do plant cells need chloroplasts?
Correspondingly, why do plant cells need chloroplasts and mitochondria?
Chloroplasts are present in photosynthetic plants and is responsible for making the food of the plant. On the other hand, mitochondria also known as the power house of the cell, uses this oxygen in order to create ATP which is used for various purposes like active transport, releasing minerals and many more in plants.
Beside above, why is the chloroplast so important? The chloroplast absorbs the energy in sunlight and uses it to produce sugars. Chloroplasts play an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars.
Accordingly, why do some plant cells not have chloroplasts?
The inner stem cells and underground organs, such as the root system or bulb, contain no chloroplasts. Because no sunlight reaches these areas, chloroplasts would be useless. Fruit and flower cells typically do not contain chloroplasts because their primary jobs are reproduction and dispersal.
Why do plant cells need cell walls?
Plant cells are actively involved in water transportation, and thus plant cell wall ensures that the cell does not burst due to over expansion as water flows in (internal turgor pressure). Besides this cell walls also provides structural and mechanical support, protection against pathogens and dehydration.
