B Correct answer
Explanation

The branch of biology concerned with the study of fungi along with their genetic and biochemical properties is called mycology. It also involves the study of their use to humans as a source of medicine and food. It combines with algae and fungi to form lichens. It also associate with root to form mycorrhiza.

Thus the correct answer is option B.

Select incorrect statement w.r.t edible mushrooms ____________________.

  1. Rhizomorph do not have root cap like structure

  2. Spawn is used for their culture

  3. Edible part is actually basidiocarp

  4. Dikaryotisation occurs by crozier formation

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Root caps are the growing part of the roots present at the tips of the roots and are formed by parenchymal cells. Rhizomorphs also have a root cap like structure and hence the first statement is incorrect. So the right answer is option 'Rhizomorph do not have root cap like structure'.

Mushroom get its food from

  1. Dead and decaying plants

  2. Photosynthesis

  3. Eating small insects which come near it

  4. The water we pour near it

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Plant mushroom get its food from dead and decaying plants. In short, they are saprophytes. Plants are green because they contain chlorophyll, which helps them with photosynthesis, the process of turning sunlight into food. Mushrooms are not green and they contain no chlorophyll. Therefore, they cannot photosynthesize. Mushrooms obtain their food by metabolizing dead or decaying organic matter, such as dead plants on the ground. Tiny filaments called as hyphae absorb the nutrients from the dead matter. Mushrooms are made up of hyphae filaments and a mass of hyphae is called as a mycelium. This is why, you often see mushrooms growing on dead tree stumps.

In mushroom cultivation, spawn is 

  1. Compost

  2. Button stage

  3. Vegetative mycelium

  4. Harvested mushroom

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mushroom Spawn is simply any substance that has been inoculated with mycelium, the vegetative growth of the fungus. Mycelium a thread like the collection of the cell is to a mushroom-like an apple tree is to an apple.

So, the correct option is 'Vegetative mycelium'.
