Question

Saprophytic angiosperms are also called
A. Mycorrhizal plants
B. Mesophytic plants
C. Humus plants
D. Myrmecophilous plants

Answer 1

Hint:These plants can grow in black, organic material that occurs in the soil as the matter of plants and animals decays. When plants lose leaves, twigs, and other material to the ground, they pile up.

Complete answer:
Saprophytes are living creatures that survive and feed on dead, rotting organisms. They are known to be highly significant in soil biology. They disintegrate the complex organic matter into simpler compounds, which are taken up by plants for different metabolic activities. As a result, saprophytes play a major role in the environment. Fungi and a number of bacteria are saprophytes.
Mycorrhizae are a symbiotic relationship between fungi and plants. The fungi colonize the root system of the host plant, supplying increased water and nutrient absorption as the plant supplies the fungus with carbohydrates produced by photosynthesis.
Mesophytic plants are plants that are suited to neither dry nor wet environmental conditions. Example: clover, etc.
Humus is the topmost layer of soil formed during the death of dead animals. Saprophytes derive nutrition from dead and rotting matter in the soil, resulting in nutrition from the humus layer. So, saprophytes are sometimes referred to as humus plants.
Plants that have an interspecies relationship with ants are called myrmecophilous plants.

Thus, the correct answer is option C i.e., Humus plants.

Note:The saprophytes secrete digestive juices and dissolve the organic matter surrounding them. Fungi develop tubular structures known as hyphae, which spread into dead matter and produce digestive enzymes.
