Chloroplast is the site for photosynthesis in plants. Thus, option A is correct.
Chloroplasts are the cell organelles present in the plants. Chloroplasts are one such type of plastids.
Chloroplasts are green in colour. They contain a green coloured pigment called chlorophyll which traps the solar energy.
The solarenergy is converted into chemicalenergy by a process called photosynthesis. The organic molecules so produced are the energyrich compounds.
Chloroplasts are chiefly found in the mesophyll region of the leaves.
Chloroplast consists of grana and stroma regions. The grana contain disc shaped coin like structures called thylakoids. The matrix of chloroplasts constitutes stroma region.
Various enzymes, DNA, ribosomes etc are found within the chloroplasts. Hence, they are also referred as 'cellwithinthecell'.
Chloroplasts have unique feature of self-replication. Chloroplasts are similar in function to mitochondria in animal cells.
Therefore, chloroplasts are important plant structures for photosynthesis.

In plants, photosynthesis takes place in chloroplasts. Option A is correct.
Plant, algae, and certain protist cells have membrane-bound organelles called chloroplasts.
So, They are in charge of the process known as photosynthesis, which turns light energy into chemical energy in the form of glucose in green plants and some other animals. Life on Earth is supported by this essential mechanism of energy conversion.
Therefore, In plants, photosynthesis takes place in chloroplasts.

Answer:
Epigenetic mark
Explanation:
A methyl group attached to the nitrogenous base of one amino acid on the DNA is known to have effects on the expression and transcripcion of the genes, and this is also called epigenetic modifications. Therefore, an methyl group attached to the DNA is responsible for epigenetic modifications and so is an epigenetic mark.
Answer:
The correct answer would be mitochondria or chloroplast.
Endosymbiosis refers to the evolution theory which explains the origin of eukaryotic cells from prokaryotic cells.
It is believed that cell organelles like chloroplast, mitochondria et cetera were free-living early prokaryotic cells which were taken inside the other cells by the process of endosymbiosis. It led to the origin of eukaryotic cells which were able to perform photosynthesis.
Thus, Keiko should mark chloroplast or mitochondria in the diagram.
Answer:
mitochondria, chloroplast
Explanation:
b. it breaks down proteins.
c. it breaks down carbohydrates.
d. it breaks down fats, proteins, and carbohydrates. check answer?
Answer:
α‑ketoglutarate dehydrogenase
Explanation:
This is an enzyme complex ,which is analogous to pyruvate dehydrogenase. . Its catalytic activity is inhibited by it products succinyl Co A,it is also refers to as oxoglutarate dehydrogenase complex.(OGDC).
This enzyme complex is similar to pyruvate dehydrogenase in having the same subunit structure, and using the same type of co-enzyme.
