NEET BIOLOGY

Detailed explanation-1: -Additionally, there is little evidence of fully functional cuticle synthesis in algae. The early evolution of cuticle is supported by the presence of cuticle in 400-million-year-old plant fossils (Niklas, 1976).

Detailed explanation-2: -The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do n ot have roots, stems, or leaves. Some algae also differ from plants in being motile.

Detailed explanation-3: -Cuticle is a useful adaptation in plants but not algae because plants need a way to retain water and algae obtains water and other materials directly from the water around them.

Detailed explanation-4: -One difference between green algae and plants is that green algae do not have a cuticle. Why don’t green algae have a cuticle? Because they live in the water so they don’t need a cuticle like plants to prevent water loss.
