Chapter 10 Cell Growth and Division

Chapter 10 Cell Growth and Division. I. Cell Growth. A . When cells are NOT dividing, DNA is found in the nucleus in the form of uncoiled chromatin. 1. What does this look like in the cell? A mass of genetic material that is spread out ; a bowl of spaghetti. I. Cell Growth.

Meiosis with Mitosis Review and Comparison (Chapters 8 and 10)

Meiosis with Mitosis Review and Comparison (Chapters 8 and 10). Recall Mitosis. ** Mitosis is asexual reproduction & occurs ONLY in regular old body cells called SOMATIC CELLS (skin, nails, your pancreas, etc..) NOT sperm and eggs ? ** Produces two identical diploid (2n) cells.

Diploid

Diploid. Cells that contain TWO sets of chromosomes (2n) One set comes from the mother and one from the father Humans have a diploid number of 46. Haploid. Cells that contain ONE set of chromosomes (1n) Haploid cells are sex cells, or gametes Humans have a haploid number of 23.

MEIOSIS

MEIOSIS. Key Concepts. Meiosis halves the nuclear chromosome content and generates diversity. Sexual reproduction requires special cells made by meiosis. Sperm and egg are produced by meiosis. Meiosis. The process of meiosis produces sex cells.

Meiosis

Meiosis. An example of reduction division. During sexual reproduction, a gamete (23 chromosomes, X or Y) from the male organism and a gamete from the female organism (23 chromosomes) fuse to create a new cell. United Streaming: Mitosis and Meiosis Part 9. Prophase I.
