Which cell is adapted for swimming?
▶️ Answer/Explanation
Ans: C
The cell adapted for swimming is typically a sperm cell or a bacterial cell with flagella. In the given diagram, Cell C has a tail-like structure (flagellum), which provides motility. This adaptation allows the cell to move efficiently in liquid environments.
Other cells (A, B, D) lack such structures and are not specialized for swimming. Thus, the correct answer is C.
The diagram shows two cells.
Which process happens in only one of these cells?
A) controlling the chemical reactions in the cell
B) controlling the movement of substances into the cell
C) making starch inside the cell
D) using glucose inside the cell
▶️ Answer/Explanation
Ans: C
The diagram likely shows a plant cell (capable of photosynthesis) and an animal cell. Starch synthesis (C) occurs only in plant cells, where glucose is stored as starch.
Options A, B, and D are common to both cell types: enzymes control reactions (A), membranes regulate substance movement (B), and both cells metabolize glucose (D). Thus, the correct answer is C (making starch inside the cell).
