Cell Structure A cell is the basic structural and functional unit of life. Although cells vary in shape and size, most have the same basic components. Main Parts of a Cell Cell wall (in plants) Rigid outer layer made of cellulose Provides shape, protection, and support Plasma membrane (cell membrane) Thin, flexible boundary surrounding the cell Controls movement of substances in and out Cytoplasm Jelly-like substance inside the cell Contains organelles and is the site of metabolic act...

Meiosis is a type of cell division that produces gametes (sperm and egg cells) for sexual reproduction. It reduces the chromosome number by half, resulting in four genetically different haploid cells from one diploid parent cell. Meiosis occurs in two stages: Meiosis I is the reduction division. Homologous chromosomes pair up, exchange genetic material through crossing over, and then separate. This stage increases genetic variation and reduces the chromosome number from diploid to haploid. Me...

The cell cycle is the series of events by which a cell grows, duplicates its genetic material, and divides to form two identical daughter cells. It is essential for growth, repair, and reproduction in living organisms. The cell cycle is divided into two main phases: Interphase and the Mitotic (M) phase. Interphase is the longest phase and consists of three stages: G₁ phase (Gap 1): The cell grows and carries out normal metabolic activities. S phase (Synthesis): DNA is replicated so that ea...
