Question

question 3 (mandatory) (2 points)
cell shape is reinforced by ____.
a) phospholipids
b) dna
c) cytoskeletal filaments
d) transport proteins

Explanation:

• Phospholipids form the cell membrane but do not reinforce cell shape.
• DNA contains genetic information and is not related to cell - shape reinforcement.
• Transport proteins are involved in the movement of substances across the membrane, not cell - shape.
• Cytoskeletal filaments (such as microfilaments, intermediate filaments, and microtubules) provide structural support and help in maintaining the cell shape.

Answer:

C. cytoskeletal filaments
