Question

Which of the following is not a function of cytoplasm?
A. Aids in the movement of different cellular elements.
B. Means of transport for genetic material.
C. Site of replication of DNA.
D. Transports the product of cellular respiration.

Answer 1

The word cytoplasm refers to a fluid material that is present within all the cells. The cell membrane encloses the cytoplasm. The cytoplasm mainly consists of water and is colorless. The cytoplasm of the cell consists of three components: cytosol, organelles, and inclusions.

Complete answer: Cytoplasm is the liquid component present within the cell. The cell membrane encloses the cytoplasm in which different cell organelles are embedded in it. The cytoplasm is mainly made up of water which constitutes eighty percent of the total volume of the cytoplasm. The cytoplasm is colorless. The cytoplasm consists of cytosol which is a gel-like substance, cell organelles, and cytoplasmic inclusions. Various metabolic activities take place within the cell. It aids in the movement of different cellular elements. It also acts as a carrier which helps in the transport of genetic material. It regulates the function of transporting the product of cellular respiration such as in glycolysis. Signaling activity which involves the movement of calcium ions in and out is important for the metabolic process to occur and is done by the cytoplasm. The cell organelles are protected by the cytoplasm from getting damage due to the collision and movement within the cell. The process of glycolysis begins in the cytoplasm of the cell. The site of replication of DNA is the nucleus and not the cytoplasm. Therefore, it is not a function of cytoplasm.

So, option C is the correct option.

Note: Cytoplasmic streaming is the movement of cytoplasm around the vacuoles in plants. The cytoplasm is enclosed by the cell membrane and provides structure and support to the cell. Cell organelles, cytoplasm are enclosed by cell membranes except for the nucleus as it is enclosed by the nuclear membrane.
