Why should your body grow new cells?

In the time it takes you to read this sentence how many new cells do you think your body will produce? Millions! Your stomach alone has so much acid that the cells in the lining have to be replaced every few days!

The Cell Cycle Chromosomes Homologous Chromosomes Binary Fission ChromatidsCentromereMitosisCytokinesis

Cell Cycle Different stages of a cell’s life Cycle begins when cell is formed…ends when cell divides to make a new cell. Ex. You go thru stages of life so does a cell! To

Binary Fission Happens in Prokaryotic cells Means “splitting into 2 parts” Results in a copy of bacteria

How do Eukaryotic cells divide?

Mitosis The way organisms replace damaged and old cells or grow new cells.

Mitosis Making or replacing cells involves copying and moving DNA to the new cell.

Chromatids Are the ½ the chromosome. Centromere: is the connection part of the X. Centromere

Chromosomes DNA organized into structures Vary in organism Ex. Humans=46, flies=8 1 “X”

Homologous Chromosomes Are 2 strands of chromosomes placed together to form an XX.

Pre-phase: Interphase Cell grows and copies organelles & chromosomes Has loose DNA The 2 copies are called chromatids.

Mitosis: Prophase Nuclear membrane breaks apart Centrioles move to opposite sides Fibers form bet. the 2 centrioles and centromeres catch the DNA.

Mitosis: Metaphase Chromosomes begin to line up

Mitosis: Anaphase Chromatids separate and move to centrioles on fibers.

Mitosis: Telophase Nuclear membrane forms around chromosomes.

Post-Phase: Cytokinesis Is when the cytoplasm splits in 2. This ends the cell cycle. ends cell cycle
