Biology Question on Kingdom Plant
In which of the following plants, reproductive structures lack a layer of sterile vegetative cells surrounding the gametes?
A
Ectocarpus
B
Riccia
C
Funaria
D
Cycas
Answer
Ectocarpus
Explanation
Solution
The sex organs in plants other than algae like in Riccia, Funaria (bryophytes) and Cycas (gymnosperm) are multicellular and jacketed. The jacket of sterile cells around the sperms and eggs is an adaptation to a life on land. In Ectocarpus (algae) sex organs are non jacketed.
