Which type of cell division is involved in growth and repair?

Mitosis

What is it called when cells grow and divide?

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.

How is cell division involved in growth?

In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues.

What cells are responsible for cell division and growth in plants?

Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Apical meristems are found at the apex, or tip, of roots and buds, allowing roots and stems to grow in length and leaves and flowers to differentiate.

What are the phases of cell division?

Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

What are the three main functions of mitosis?

Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.

What is the main function of prophase?

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

What are the key features of prophase?

In prophase,

  • chromosomes condense and become visible.
  • spindle fibers emerge from the centrosomes.
  • nuclear envelope breaks down.
  • nucleolus disappears.

What happens during Diakinesis?

diakinesis. the final stage in the first meiotic prophase in gametogenesis, inwhich the chromosomes achieve their maximum thickness. The chiasmata and nucleolus disappear, the nuclear membrane degenerates, and the spindle fibers form in preparation for the formation of dyads.
