send digestive enzymes outside the organisms body to break down its food, then it takes in the smaller, digested monomers through the body.

Question 21

True

Question 22

Which the following statements inaccurate about fungal mycelia?

(i) Fungal hyphae make up fungal mycelia
(ii) Mycelia are almost always composed of diploid cells.
(iii) Mycelia are generally found underneath a substrate.
(iv) They are generally found in moist habitats.
(v) They can extend over great distances with a large suface area.

Answer 22

(ii) Mycelia are almost always composed of diploid cells, is an inaccurate statement about fungal mycelia.

Question 23

Why are fungi excellent decomposers in the environment?

Answer 23

Fungi can produce unique digestive enzymes.

Question 24

In some stages of a fungal life cycle, there are dikaryotic cells; that means that the cells have ..?.. inside them during those stages of the life cycle.

Answer 24

two un-fused haploid nuclei

Question 25

The Zygomycota (of which the black bread mold Rhizopus is an example) are characterized by a zygospore stage and a sporangiophore stage in the life cycle. What is the importance of the zygospore stage?

Answer 25

It is the only diploid cell in the life cycle

Question 26
