Prentice Hall Biology. 10-2 Cell Division. Cell Division. In eukaryotes, cell division occurs in two major stages . The first stage, division of the cell nucleus, is called mitosis. The second stage, division of the cell cytoplasm, is called cytokinesis. Chromosomes. Chromosomes

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.

Meiosis

Meiosis

Meiosis. First nuclear division 46 X’s split into 2 nuclei with 23 X’s (one of each kind of chromosome) Second nuclear division 23 X’s split into 2 nuclei with 23 single copy chromosomes Cytokinesis follows both divisions, but interphase only follows second division. Meiosis (Prophase I).

Cell 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.

Meiosis

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.

The cellular basis of reproduction and inheritance.

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.

Sexual Reproduction

Sexual Reproduction

Sexual Reproduction. Meiosis . During sex reproduction…. Fertilization occurs (sperm and egg come together). Generally the egg and sperm come from different organisms of the same species (e.g. male and female lion). New cell is called a zygote. Types of Cells:.

CELL GROWTH AND DIVISION

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

Chapter 10 Notes. Cell Growth and Division. I. The Cell Cycle. Interphase: the portion of the cell cycle between divisions 1. About 75 – 80% of the life of the cell 2. 3 phases: a. G 1 : cells grow and develop b. S: chromosomes replicate.

Chromosomes and Genes

Chromosomes and Genes. 1. Define the following terms. Zygote – cell formed from 2 gametes after fertilization Dominant – capital letter/ main characteristic Recessive – small case letter/ must have two of the same to have this physical characteristic

MEIOSIS

MEIOSIS

MEIOSIS. Why Meiosis?. Meiosis is a form of cell division that produces haploid cells. A haploid cell contains one full set of chromosomes. In human, the haploid cells are the sex cells – sperm & egg – which contain 23 chromosomes. Sex cells = gametes = germ cells.

meiosis. * Mitosis produces 2 exact copies of “body” cells In meiosis, sex cells (gametes) are produced Body cells are diploid which means they have 2 of each chromosome, or a pair of each chromosomes. {1 from mom, 1 from dad}.
