The question is incomplete as it does not have the options which are:
I. Cardiac cells are joined by gap junctions and contain three nuclei.
II. Mature platelet cells do not contain a nucleus, but do contain mitochondria.
III. Spermatogonia undergoing mitosis.
IV. The bulk of tissue samples from endocrine glands contain cells as their main building blocks.
Please choose from one of the following options.
A. II only
B. I and III
C. II and IV
D. III and IV
Answer:
The correct answer will be option-D) III and IV
Explanation:
The cell theory was proposed by the Schleiden, Schwann and Rudolf Virchow which stated that:
1. The structural and functional unit of life is a cell.
2. The cells arise from the pre-existing cells only
3. The living organisms are composed of the cells.
In the given question, since the cell theory did not proposed statements related to the cell organelles and cell to cell communication as discussed in the I and II, therefore, they do not fulfil the conditions of the cell theory.
The process of mitosis is the process related to the cell division which forms the daughter cell from a parent cell and the tissue is made of the cell which is the basic unit of life, therefore, fulfil the condition of cell theory.
Thus, Option-D is the correct answer.
