Question

Sexual life cycle of toadstools is different from Albugo in the presence of
A)Flagellated gametes
B)Diplophase
C)(n+n) phase
D)Meiosis

Answer 1

Mushroom is referred to as the fruiting body of the fungus, they are member of the phylum
Basidomycota, they are spore bearing, and it is a food source. And the Agaricus is a genus of member mushrooms.

Complete answer:
The life cycle of mushrooms is composed of three stages; spores falling, hyphae developing, and finally mycelium forming. The synthesis and release of spores are completed by the gills that are present under the mushroom cap.

The cap pulls in organic matter throughout the soils to the mushrooms. In this part of the mushroom life cycle the caps are generally utilized for the absorption of organic matter as nutrients for the growth of mushrooms.
These spores are either single cell male or female connected together to give rise to hyphae. Once one spore's hyphae interact with another spore's hyphae they meet and combine to be the mechanism of mycelium growth.

Now, Agaricus and also toadstool is a member of mushrooms, during maturation the body consists of vegetative mycelium found in the soil and sporophyte that have flagellated gametes. formed the spore after the growth above the soil.
The vegetative part of the mycelium is made up of two filamentous hyphae that give rise to the basidiospores.

At the start, the hyphae are nucleated but later two strains of hyphae are developed and both of them come in contact as a result the nucleus passes from one to the other this process is named as somatogamy. The cells become dikaryotic but remain monokaryotic in toadstool.

Hence, the correct answer is option (B)

Note: The gills in the cap fastly divide to give rise to the mushroom. The division in the gills in the cap is performed for the development of mushrooms and the basidia is involved in the bearing of the sexual reproductive part called spores.
