Flashcards

Mitosis

The process by which a single cell divides into two identical daughter cells.

Cell Cycle

The series of phases that a cell goes through from its birth to division.

Interphase

The first stage of the cell cycle, where the cell grows, replicates its DNA, and prepares for division.

Cytokinesis

The process of dividing the cytoplasm and cell membrane to create two new cells.

Study Notes

Mitosis and the Cell Cycle

The cell cycle is a series of steps a cell undergoes to divide
Mitosis is a stage in the cell cycle when the cell divides
Stage 1 (Interphase):
- The cell grows
- Organelles increase in number
- Proteins are synthesized
- DNA replicates (forming an 'X' shape)
- Energy stores increase
Stage 2 (Mitosis):
- Chromosomes line up at the cell's equator
- Cell fibers pull each chromosome to opposite sides of the cell
Stage 3 (Cytokinesis):
- Cytoplasm and cell membranes divide
- Two identical daughter cells form
Importance in multicellular organisms:
- Crucial for growth and development
- Important for replacing damaged cells
Importance in asexual reproduction:
- Involves one organism
- The organism replicates its cells to produce offspring
Genetic material:
- The nucleus contains genetic information

Description

This quiz explores the key stages of the cell cycle, focusing on mitosis, where a cell divides to form two identical daughter cells. Detailed descriptions of interphase, mitosis, and cytokinesis will help reinforce understanding of these fundamental biological processes. Discover the importance of mitosis in growth, development, and asexual reproduction.
