Question

What is not true of spherosomes?
A) Single membrane covering
B) Connected with fats
C) Arise from endoplasmic reticulum
D) Involved in photorespiration

Answer 1

Hint: Living cells have different organelles like cytoplasm, chloroplast, nucleus, mitochondria, etc. and all these organelles have different structure and function that work together to make the cell live.

Complete Answer:
- Cell organelles are small organ-like structures with specific function. The mitochondria and chloroplast are organelles that are double membrane bound.
- The outermost layer of the cell is cell membrane, it is selectively permeable that allows the movement of materials in or out of the cell. Below the cell membrane, a cell wall is present but it is only found in plant cells, it is also permeable in nature, and made of cellulose and peptidoglycan.
- Cytoplasm is the next part of the cell that contains 90 percent of water and organic and inorganic compounds; it is colloidal and viscous in nature, and jelly like fluid inside the cell.
- The nucleus is composed of RNA, DNA, and protein, nucleolus, and chromatin network, next is the mitochondria that is considered as the power house of the cell as it stores energy in form of ATP molecules, golgi bodies is a sac-like vesicles and cisternae has cis and trans face, the endoplasmic reticulum is a membrane network that have rhibosomes involve during translation process.
- Now, spherosomes are small organelles found in the cytoplasm covered by a single membrane that is involved in the synthesis and storage of lipids. They are formed from the endoplasmic reticulum; they are surrounded by a single phospholipid monolayer. This organelle is only found in plant cells.
- Spherosomes are also termed as oleosomes. Among the given options, this organelles is not involved in the photorespiration process.

Thus, the correct option is ‘D’. Involved in photorespiration.

Note: Cytoplasm works as a buffer and also involves in the protection of the genetic materials of the cell. It even involves in the protection of cellular organelles from damage. And the most important function of cytoplasm is that it is the site for cellular respiration.
