Answer True of False for the following statements a Lichens

Answer True of False for the following statements:

a) Lichens are related to photosynthetic fungi.

b) Organic material may flow from one cell to another in hyphae.

c) All fungi are autotrophic.

d) The thread-like shape of fungal hyphae give them a large surface:volume ratio that helps them absorb compounds from the environment.

Solution

a) Lichens are formed by symbiotic relation between photosynthetic algae and fungi. Fungi do not perform photosynthesis. The given statement is false.

b) The filamentous structures in fungal body are called hyphae. The cytoplasm flows from one cell to another through hyphae. The nutrients are obtained by producing digestive enzymes into substrate and absorb them. Organic material flow from one cell to another through cytoplasm. The given statement is true.

c) fungi are heterotrophic, nonphotosynthetic and obtain food from the substrate on ewhich they are grown. The given statement is false.

d) The thread like filamentous hyphae provide the fungi large surface area that spread throughout the substartum and useful for absorption of nutrients. The given statement is true.
