Study Notes
Cell Cycle and Division
- DNA is copied during the S phase (synthesis phase) of the cell cycle.
- Cytokinesis in an animal cell results in the formation of two separate daughter cells through the constriction of the cell membrane.
- The longest stage of the cell cycle is Interphase, which includes the G1, S, and G2 phases, primarily focused on cell growth and DNA replication.
- A cell typically takes about 24 hours to complete the entire cell cycle, though this can vary depending on the cell type.
- An animal cell divides through a process known as mitosis, which ensures equal distribution of chromosomes to the daughter cells.
Cell Theory and Structural Organization
- The basic unit of life is the cell, which represents the lowest level of organization in biological systems.
- A postulate of the unified cell theory that might be considered NOT true could include misconceptions about cell origin, since all cells arise from pre-existing cells.
- The term "cell" was coined by Robert Hooke, who used it to describe the box-like structures he observed in cork tissue in the 17th century.
Cellular Functions
- Mitochondria are responsible for producing energy in the form of ATP through cellular respiration, acting as the powerhouse of the cell.
- The Golgi apparatus functions in the modification, packaging, and distribution of proteins and lipids that are synthesized in the cell, playing a crucial role in secretion and delivery of cellular products.
