Question

All fungi differ from algae in
A. Lacking chlorophyll
B. Lacking pyrenoids
C. Types of spores in reproduction
D. All of the above

Answer 1

Hint: Algae are grouped under kingdom Plantae, while fungi constitute a separate kingdom according to the five-kingdom classification proposed by the scientist, Whittaker.
These taxonomic groups are created based on the similarities present between two organisms.

Complete answer: The primary distinguishing factor between fungi and algae is that algae have photosynthetic pigments in structures called chlorophyll, and are therefore able to prepare their own food.
Fungi on the other hand are devoid of any pigments and they are strictly heterotrophic in nature and obtain their nutrition from organic substances in the environment.
Algae also contain pyrenoids, a protein body that is heavily involved in carbon fixation, starch formation, and storage; fungi lack pyrenoids.
Given below are the diagrams of fungi (left) and algae (right):

So, the correct answers are both A. Lacking chlorophyll and B. Lacking pyrenoids.

Note: Both algae and fungi reproduce by spore formation.
Under favorable situations, these spores germinate and give rise to a new organism by undergoing mitotic division and produce a multicellular gametophyte.
