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'.

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.

Fungal tissue is known as plectenchyma that is formed due to well organized hyphae either forming parallel strand-called parenchyma or give the appearance of parenchyma of higher plants called pseudoparenchyma.

Fungi are saprophytes in nature. They tend to live on dead organisms. They do not possess chlorophyll. Their cell wall is made up of chitin.

1. Agaricus bisporus from the above options is an edible mushroom which is a native of grassland of Europe and North America.
2. Rest of the mushrooms Amanita phalloides (Death cap), Omphalous olearius (Jack O Lantern) and fungus of genus Entoloma are all poisonous and not eligible for human consumption as they me cause sever cramps and vomiting and other symptoms.

Mature gill composed of a central core called trema which is made up of parallel or loosely interwoven hyphae.

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.

Fungal cell walls are primarily composed of chitin and glucans. Cellulose is typically found in plant cell walls, and lignin is a structural polymer in vascular plants.
