Question 4
The cell could come from A. skin. B. liver. C. testes. D. bone marrow.
Worked Solution & Example Answer:The cell could come from A - VCE - SSCE Biology - Question 4 - 2002 - Paper 1
Step 1
A. skin.
Answer
The skin is composed of epithelial cells known as keratinocytes, which can regenerate and do not typically contribute to cellular sources discussed in deeper biological contexts.
Given the nature of the question, while skin has cellular activity, it is not the primary source for certain specialized cell types.
Step 2
B. liver.
Answer
The liver is a vital organ that contains hepatocytes, which play essential roles in metabolism, detoxification, and protein synthesis. However, it is not commonly viewed as a source for the specific type of cell in focus.
Thus, while liver cells are significant, they may not be the best option.
Step 3
C. testes.
Answer
Testes produce sperm cells through a process called spermatogenesis. The cells found in this organ are key in reproduction, but they typically represent a specialized category of cells, making them less likely as a general source for any cell type.
This could potentially pertain to reproductive cell discussions.
Step 4
D. bone marrow.
Answer
Bone marrow is the primary site for hematopoiesis, the process by which all blood cells are produced, including red blood cells, white blood cells, and platelets. Given its crucial role in generating various cell types, bone marrow is often considered the best answer when discussing potential sources for diverse cell types.
Therefore, the correct answer would most likely be 'D. bone marrow.'
