Definition: The endomembrane system includes a group of membranous organelles that work together in a coordinated manner to perform specific cellular functions. Components of the Endomembrane System: Endoplasmic Reticulum (ER): Network of membranous tubules and sacs. Plays a role in synthesis, folding, modification, and transport of proteins and lipids....
Key Concept: All organisms, no matter how large, begin life as a single cell. Growth and reproduction are fundamental characteristics of cells. Cell Growth and Division: A single cell divides and gives rise to two daughter cells. Daughter cells grow and divide further, forming a population of cells. Repeated...
Overview: The cell cycle varies in duration depending on the organism and cell type. Human cells: ~24 hours. Yeast cells: ~90 minutes. Two major phases: Interphase: Preparation for division (95% of the cycle). M Phase (Mitosis Phase): Actual cell division. M Phase (Mitosis Phase): Definition: Phase where the cell...
Overview: M Phase (Mitosis Phase): The most dramatic period of the cell cycle, involving significant reorganization of the cell’s components. It is also called equational division because the number of chromosomes in both the parent and daughter cells remains the same. Though mitosis is divided into four main stages,...
Overview: Prophase is the first stage of karyokinesis in mitosis. It follows the S and G2 phases of interphase, where DNA replication occurs. During S and G2 phases, new DNA molecules are intertwined and not distinct. Prophase is marked by the condensation of chromosomal material and several cellular changes....
