Cellular Reproduction

Cellular Reproduction. Cell Division cellular material is divided between new daughter cells Nuclear division: Mitosis or Meiosis Cytoplasmic division: Cytokinesis. Mitosis and Meiosis in the Human Life Cycle. 2n = diploid = 2 sets of chromosomes

Passive transport Active transport Exocytosis Endocytosis

Membrane Transport. Passive transport Active transport Exocytosis Endocytosis. Membrane Transport. Facilitated diffusion. Channel proteins and carrier proteins. Membrane Transport. Active transport requires energy to move molecules across a membrane. Lower solute concentration.

Sexual Reproduction

Sexual Reproduction and Meiosis. 2. Sexual Reproduction. During sexual reproduction , two sex cells, sometimes called an egg and a sperm, come together. Sex cells are formed from cells in reproductive organs. Sperm are formed in the male reproductive organs.

Cell Division

Cell Division. Cell Cycle, Mitosis, and Cytokinesis. Chromosomes. Are bundled packages that contain genetic information (DNA). Must be copied before cell division begins. Make the process of separating DNA during cell division possible. Chromosomes. There are two types Prokaryotic
