Explanation:

- 3.2.1

Mitosis is a kind of cellular division that produces two genetically identical daughter cells. Whereas, cloning is a technique used to create identical cells. This means that mitosis applies to cloning.

- 3.2.2

A chromatid is a half of a replicated chromosome. Together, a replicated chromosome is called SISTER CHROMATIDS. One of them is called a Chromatid. Spindle fibre is a structure involved with the division of the genetic material during cell division.

- 3.2.3

The cell cycle consists of two stages interphase and mitotic phase. Hence, interphase and mitosis are part of the cell cycle.

- 3.2.4

A tumour is a cancerous mass of cells. Tumour can either be BENIGN i.e. not capable of spreading to other parts or MALIGNANT i.e. capable of spreading to other parts.

- 3.2.5

Cancer is an uncontrolled division of cells and can occur in virtually all organs of the body. Bone cancer is a type of cancer that affects the bone cells. However, carcinoma (starts in the skin) and leukaemia (blood cancer) are unrelated to bone cancer.
