Answer:
Because it is a mode for reproduction and growth.
Explanation:
Cell division is important for both single-celled as well as multi-cellular organisms.
In single-celled organisms, the cell division is the process which helps them to reproduce and form new organisms.
In multi-cellular organism, the cell division becomes more important because both, the division and growth in cells of multi-cellular organism occurs by means of cell division. When cells divide, the number of cells increases and it is seen as a overall growth in the organism. Damaged tissue repair is also accomplished by the cell division itself.

The cell cycle involves the interphase and mitotic phase. Interphase stage is the stage where the cell grows, multiplies its genetic material and generally prepare while mitosis is the nuclear division.

Benign tumor are mass of cancerous cells that do not spread to other parts.
- 3.1.10
A chromatid is the half part of a replicated chromosome. Together, they are called SISTER CHROMATIDS.
Answer:
Up and down
Explanation:
In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.
