• B. Yeast, Mushroom, Bread mould
• C. Paramecium, Amoeba, Cuscuta
• D. Cuscuta, Lice, Tapeworm

Answer 1

The correct option is B

Yeast, Mushroom, Bread mould

The correct option is B:

Explanation of the correct option:

1. Fungi are organisms that break down dietary components.
2. Extracellular digestion is the breakdown of dietary material into simple compounds outside the body.
3. Food is broken down outside the body with the help of hydrolytic enzymes secreted by the organism in this process.
4. Because fungus lack a functioning digestive system, this process happens mostly in them.
5. On the food component, the fungus secretes hydrolytic enzymes that break down the food into simple molecules or nutrients. The nutrients released are then absorbed by the fungus cells.
6. Yeast, Mushroom, and Bread mould are fungi and fungi is an organism that breaks down food into simple chemicals outside of the body before absorbing it.

Explanation of the incorrect option:

Option A:

Only fungi breaks down food outside the body and green plant and amoeba is not fungi.

Option C:

Only fungi breaks down food outside the body and Paramecium, Amoeba, and Cuscuta fungi.

Option D:

Only fungi breaks down food outside the body and Cuscuta, Lice, and Tapeworm is not fungi.

Final answer: Yeast, Mushroom, Bread mould are groups of organisms that breaks down food outside the body and absorbs.
