Answer:
Why would a plant cell have a chloroplast while an animal cell wouldn't? Chloroplasts are used to make food through photosynthesis. Plant cells make their own food, while animals do not.
Photosynthesis is an example of an endergonic reaction. It is a type of reaction in which the energy is absorbed.
Photosynthesis refers to a set of reactions that uses solar energy, water and carbon dioxide in association with the pigment chlorophyll to produce organic compounds. Solar energy is converted into chemical energy in the form of ATP and NADPH. The chemical energy in these energy rich molecules is then used for the next step of photosynthesis for the fixation of the carbon.
Thus, photosynthesis is an endergonic reaction in which the solar energy is used to fix the carbon dioxide, transferring the energy into the carbohydrates formed and releasing oxygen.
They speed up chemical reactions
Had to look for the options and here is my answer:
Drosophila is considered as a specie of flies, often known as "fruit flies".
