Question

In Albugo, sexual reproduction result in the formation of
A. Zoospores
B. Teliospore
C. Oospore
D. Basidiospore

Answer 1

Hint:
Albugo are plant parasites belonging to oomycetes but they are not true fungi. They need a living host for reproduction. They reproduce both sexually by producing oospores and asexually by producing sporangia.

Complete answer:
In this question, we have asked about spores of albugo. As we already mentioned, Albugo are plant parasites. They cause a disease named white rust. They need a host for growing and reproducing. They reproduce both by sexual and asexual reproduction. Asexual reproduction takes place by conidiosporangia. They form branched hyphae called conidiophores. These spores germinate by forming a germ tube or by biflagellate zoospores.
In sexual reproduction, two sex organ antheridium and oogonium develop in stem. The antheridium and oogonium are present near each other so they do not need flagella to move. When they reproduce sexually, oospores are formed. So, the first option is zoospores. As we know, the zoospore is form during asexual reproduction in some algae and fungi. The 2nd option is teliospore. Teliospore is a spore of rust fungi that give rise to basidium. The 3rd option is zoospores. As we already mentioned, Albugo reproduce sexually by forming oospores. So, this option is true. The last option is Basidiospores. Basidiospores are reproductive spores of Basidiomycetes like mushrooms and Smuts. So, the result of sexual reproduction in Albugo produces oospores.

So, the correct option is C. Oospores.

Additional information:
As we already mentioned, albugo causes a disease named rust. The disease can be controlled by:
1. By crop rotation.
2. By removing infected plants.
3. By spraying fungicides like Bordeaux mixture.

Note: An oospore is a diploid, thick-walled sexual spore, the wall is made up of chitin. It develops from a sexually reproduced oosphere in some algae, fungi, and Oomycetes.
