Structure and function of cilia and flagella

Cilia and flagella are hair-like, microtubule-based structures extending from the cell surface. Their flexible, whip-like or oar-like design allows them to beat or rotate, generating the mechanical force needed for cellular movement or moving fluids across the cell surface.

Consequences of lacking cell walls in plants

Without rigid cell walls made of cellulose, plant cells would lose structural support and turgor pressure, causing the plant to wilt and collapse. Additionally, the cells would be highly susceptible to bursting (lysis) in hypotonic environments.

Importance of semi-permeable cell membranes

A semi-permeable membrane allows the cell to selectively regulate the entry and exit of substances. This selective transport is essential for maintaining internal homeostasis, importing nutrients, exporting wastes, and preventing harmful substances from entering.

<answer>

Question 1

Their hair-like, flexible microtubule structure allows them to beat or whip, generating the mechanical force needed for cellular movement or moving fluids across the cell surface.

Question 2

The plant would lose structural support and wilt or collapse, and its cells would easily burst (lyse) due to osmotic pressure.

Question 3

It allows the cell to selectively regulate what enters and exits, which is essential for maintaining internal homeostasis and importing nutrients while keeping out harmful substances.
