Worked Solution & Example Answer:In a multicellular organism, the term ‘internal environment’ refers to the A - VCE - SSCE Biology - Question 10 - 2008 - Paper 1
Step 1
Identify the term ‘internal environment’
Answer
In biology, the term ‘internal environment’ typically refers to the conditions that exist within an organism, distinct from the external environment. In multicellular organisms, this includes the various fluids and substances that support cellular functions.
Step 2
Evaluate each option
Answer
A. Cytoplasm: This is a part of the cell where organelles are suspended. It contains the cell’s internal structure but is not limited to it.
B. Cell organelles: These are specialized structures within the cell that perform various functions but do not represent the entirety of the internal environment.
C. Nuclear regions: This refers specifically to the area surrounding the nucleus, not the overall internal environment of the cell.
D. Extracellular fluid: This refers to the fluid that exists outside of cells but is not part of the internal environment of a multicellular organism.
