The cellular basis of reproduction and inheritance.

The cellular basis of reproduction and inheritance. Chapter 8. How do cells divide? Is this important?. Organisms are made of cells. All cells come from cells. Cells reproduce. Mitosis makes new cells. This is asexual reproduction. Organisms reproduce. Meiosis is sexual reproduction.

Cell Reproduction

Cell Reproduction. Mitosis & Meiosis. Cell Cycle. G1 (Gap 1) - cells carry out normal metabolic activities for day to day functions. S (Synthesis) - DNA is replicated (duplicated, copied). G2 (Gap 2) - cell prepares for cell division by doubling cell organelles. Mitosis.

The Cell Cycle

The Cell Cycle. Types of Cell Division. Mitosis provides cells for growth, cell replacement, and asexual reproduction maintains chromosome number Meiosis produces cells for sexual reproduction reduces chromosome number by half. Chromosome Replication. All the DNA is duplicated.

CELL GROWTH AND DIVISION

CELL GROWTH AND DIVISION. Chapter 10, section 1. Limits to Cell Growth. There are two main reasons why cells divide rather than continuing to grow indefinitely. The larger a cell becomes, the more demands are placed on its DNA

Meiosis

Meiosis. By Jessica Sheeder Added to by Janet Baity. Meiosis. Is a special type of cell division that happens only in sex cells (reproductive organs) During meiosis the cell goes through two cell divisions Meiosis 1 Meiosis 2. Meiosis 1.
