Solution

1)

The power house of the cell is called mitochondria. In eukaryotes, the surface area to volume ratio is less, but in mitochondrion, the ratio of the surface area of its inner membrane to its matrix volume is high (because the mitochondrial inner membrane is compartmentalized into numerous cristae to increase the surface area). This is important because the high surface area is essential to enhance the ATP synthesizing ability of mitochondria.

Thus, the correct option is (D).

2)

The centrioles do that proper segregation of chromosomes.

3)

A large central vacuole is specific to the plant cells, but not for animals.

4)

Organ level organization

5)

All of the above

6)

The nucleus that contains all the cells DNA

7)

The plasma membrane

8)

The plastids
