Cell cycle consists of two basic phases, long non-dividing I phase and a short-dividing M phase. In the average duration of 24 hours in the cell cycle of a dividing human cell, M phase lasts for one hour (less than 5% of total ) while I phase or interphase occupies 75-95% of total generation time.

Answer:
The correct statements about cell division are:

(i) M phase represents the phase when actual cell division occurs and I phase represents the phase between two successive M phases.
(ii) In the 24 hours average duration of cell cycle of a human cell, cell division proper lasts for only about an hour.

Explanation:
Cell division is a fundamental process that allows organisms to grow, develop, and repair damaged tissues. It involves the replication and distribution of genetic material to ensure that each daughter cell receives a complete set of chromosomes. The cell cycle consists of several phases, including interphase (I phase) and mitosis (M phase).

(i) M phase represents the phase when actual cell division occurs and I phase represents the phase between two successive M phases:
- The cell cycle is divided into two main phases: interphase (I phase) and mitosis (M phase).
- Interphase is further divided into three subphases: G1 phase, S phase, and G2 phase.
- During interphase, the cell undergoes growth, DNA replication, and preparation for cell division.
- M phase, or mitosis, is the phase when actual cell division occurs. It consists of several stages, including prophase, metaphase, anaphase, and telophase.
- After mitosis, the cell enters interphase again, completing one full cycle of cell division.

(ii) In the 24 hours average duration of cell cycle of a human cell, cell division proper lasts for only about an hour:
- The duration of the cell cycle varies among different organisms and cell types.
- In general, the average duration of the cell cycle in humans is approximately 24 hours.
- However, the actual process of cell division, which occurs during mitosis, is relatively short.
- Mitosis typically lasts for only about an hour, while interphase occupies the majority of the cell cycle duration.

Therefore, both statements (i) and (ii) are correct. M phase represents the phase when actual cell division occurs, and I phase represents the phase between two successive M phases. In the 24 hours average duration of the cell cycle of a human cell, cell division proper lasts for only about an hour.
