Question

Which sentence describes the distinction between algae and plants?

Algae and plants are both eukaryotes that photosynthesize their own food. However, there are important distinctions between these two groups that cause scientists to distinguish between them.


A) Algae are unicellular, while plants are multicellular.

B) Algae use pigments other than chlorophyll in photosynthesis, while plants only use chlorophyll to photosynthesize food.

C) Algae lack the cellular complexity to possess true leaves, stems, and roots that are present in all plants. A

D) Algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.

Answer 1

Correct answer: D). Algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.
Algae and plants are similar as both of them produce their own food by the process of photosynthesis. The main difference is found in their complexity.
The cell wall of the plants is made of cellulose, hemicellulose and pectin, and polysaccharides, while the cell wall of algae is made up of chitin, which is a polysaccharide derived from glucose.
