a. lack a reproductive phase

b. contains hyphae

c. has spores contained in ascus

d. has spores contained in basidia

Answer is C. Truffles has spores contained in the ascus.

Fungi like yeasts, molds and mushrooms are eukaryotic organisms which acts as main decomposers in the environment. Black truffles are aromatic edible fungi which belong to the ascomycota phylum. They are expensive and normally seen in the southern Europe. The main feature of the ascomycota is the ascus, a sexual spore bearing cell containing spores called ascospores. Black truffles are round shaped with black-brown skin and has small pyramidal cusps. It contains tightly interwoven hyphae (long filament like structure) and numerous asci (spore bearing cells). Each ascus contains some spores called ascopores, which is specific to fungi classified as ascomycetes. Mushrooms belong to the basidiomycota phylum. They are also composed of hyphae and reproduce sexually via the formation of specialized cells called basidia which have spores called basidiospores.

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human

B. putting more red blood cells into circulation when atmospheric oxygen levels decline.

<h3>What are stomata?</h3>

The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.
