Question

Which organelle is considered as selectively permeable?
A. Cell membrane
B. Nucleus
C. Lysosomes
D. Mitochondria
E. Vacuole

Answer 1

Hint: Living cells have various organelles, such as cytoplasm, chloroplast, nucleus, mitochondria, etc., and all these organelles have different structures and functions that work together to make the cell live. When it enables the passage of water within the cell or cell organelles, the membrane is called selectively permeable. Water from the higher concentration moves to the lower concentration in this process.

Complete answer: -A thin layer called the cell membrane encloses each cell, prokaryotic and also eukaryotic. The transfer of particles through it is one of the most significant functions of the plasma membrane. The membrane is selectively permeable on either side of a few of the molecules present.

-The nucleus comprises genetic materials that regulate the function, division, and maintenance of inherited characters of the cell. The nucleus consists of the network of RNA, DNA, and protein, nucleolus, and chromatin.
-Mitochondria is known to be the powerhouse of the DNA-composed cell, it stores the cell's ATP molecules, and it is the respiratory site.
-The lysosomes are involved in food intracellular digestion and the vacuole originate from the endoplasmic reticulum and golgi bodies, supplying the plant cell with turgidity and rigidity. The lysosome is the organelles involved in the digestion of cells consisting of enzymes, so it reflects polymorphism as it has different forms and acts by breaking down the junk portion of the cell.
Thus, the correct answer is option A, i.e., Cell membrane.

Note: Only in plant cells, the cell is located. It is completely absent in animal cells. Therefore, the cell wall is also permeable in nature to allow the transpiration process and also to absorb water molecules within the plant cell.
