As according to chegg policy, I have to answer first four questions, incase of MCQs. In case you have any problem in these questions, feel free to ask.

QUESTION 102

Which of the following is not part of a virus?

ANSWER IS:

mitochondria

EXPLANATION :

A virus is not a cell and it is a strand of nucleic acid surrounded by a protein coat. Viruses don't have mitochondria as they depend upon host for replication.

QUESTION 103

Which of the following is a difference between fungus and plants?

ANSWER IS:

fungus are heterotrophs, plants are autotrophs

EXPLANATION:

Fungi have non-motile sperm

Fungi have cell walls made of chitin and plants of cellulose.

Fungi and plants both contain mitochondria. Unlike plant cells, fungal cells do not have chloroplasts. As fungus are heterotrophs, plants are autotrophs so plants need chloroplasts and not fungi.


QUESTION 104

ANSWER IS:

hyphae

EXPLANATION :

Fungus use hyphae to feed. They are hetrotrophic and produce long, slender threads called as hyphae that spread through their food. These hyphae release enzymes that break down the food into simple products that fungi can easily absorb.
