In eggs, Ca+2 plays an important role especially at the time of fertilization. Therefore _ are present in many thousand numbers inside the cell membrane.
Correct answer: D. Endoplasmic Reticulum
- A. Ribosomes
- B. Chloroplast
- C. Mitochondria
- D. Endoplasmic Reticulum
Explanation
It is known that the Endoplasmic reticulum acts as a reservoir for Ca2+ in cells as in contractile cells. Since Ca2+ plays an important role in fertilization therefore many Ca2+ in the form of the Endoplasmic reticulum should be present.
