Class 11 Biology Chapter 10 Cell Cycle and Cell Division: Important Topics

A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Interphase

Interphase, also known as the resting phase of the cell cycle, is the time during which the cell prepares for division by undergoing both cell growth and DNA replication. It occupies around 95% time of the overall cycle. The interphase is divided into three phases, G1 phase (Gap 1), S phase (Synthesis), and G2 phase (Gap 2).

M Phase

This is considered to be the mitotic phase or the phase of the equational division as the cell undergoes a complete reorganization in order to give birth to a progeny that has the same number of chromosomes as the parent cell.

The mitotic phase is categorized into four overlapping stages:

Prophase,
Metaphase,
Anaphase, and
Telophase

Cytokinesis

In this phase, the cytoplasm of the cell divides, and begins as soon as the mitosis ends. Plant cells are much tougher than animal cells, as they have a rigid cell wall and high internal pressure. Thus, cytokinesis occurs in plant and animal cells differently.

Read the following passage and answer the questions that follow:
India is one of the megadiverse countries housing around 8·1 per cent of global species diversity, although its land area is only 2·4 per cent of the world’s land area. Many of the species are highly threatened due to human activities like deforestation, mining and habitat fragmentation. Laws like Wildlife (Protection) Act, 1972 were enacted by the Government of India to preserve our biological wealth. Various conservation measures are being implemented to save the threatened species. The following bar graph shows the number of species conserved under different biodiversity conservation methods.

Which other methods shown in the diagram are opposite to the one identified by you in question ? How are these two conservation approaches different?
