Which one of the following is representing the group of diatoms?
Correct answer: A. Pinnularia, Navicula, Cymbella, Melosira
- A. Pinnularia, Navicula, Cymbella, Melosira
- B. Euglenamorpha, Hedneria , Heteronema, Colacium
- C. Nostoc, Anabaena, Aulosira, Cylindrospermum
- D. Cochlodinium, Gymnodinium, Lenodinium, Peridinium
Explanation
Pinnularia, Navicula, Cymbella and Melosira are all recognised diatom genera. The other groups contain euglenoids, cyanobacteria or dinoflagellates, so the trap is grouping aquatic microorganisms together without checking their classification.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
