2) Which of the following is NOT one of the main components of the cell theory?

A) Cells must contain DNA

B) All cells come from other cells

C) All living things are made of cells

7) A class of chemical called a neurotransmitter is important in the transmission of nerve impulses. Neurotransmitters are packaged by the cell into small, membrane-bound sacs called vesicles. Upon receiving a chemical signal, the vesicles move toward the cell membrane and fuse with it, releasing the enclosed neurotransmitters from the terminal end of the nerve cell. Which organelle is most likely responsible for packing neurotransmitters into a vesicle?

A) Nucleus

B) Mitochondria

C) Golgi apparatus

The cell theory was proposed by the Schleiden and Schwann in 1839 which stated that all organism is made up of the cell, the cell is the structural unit of life and further modified by Virchow which added that cells arise from pre-existing cells.

Since cell theory does not discuss the genetic material of the organisms, therefore, option-A is the correct answer.

Case II

Neurotransmitters are the molecules which act as chemical messengers as well as hormones. The neurotransmitters play an important role in the signalling through the nervous system they help convert the electrical signal into chemical signals.

The neurotransmitters are stored in the vesicles in the dendrite synaptic knob which are packaged by the membrane formed by the Golgi apparatus.

Thus, Option-C is the correct answer.
