Slide 1

Cell Reproduction

Cell Reproduction

Prokaryotes Bacteria

Eukaryotes Plants & animals

Slide 2

Prokaryotes

Prokaryotes

Lack a nucleus

Have a single chromosome

Reproduce by binary fission

Include bacteria

Slide 3

Steps in Binary Fission

Steps in Binary Fission

Used by bacteria

Cells increase their cell mass slightly

DNA & cell components are replicated

Each cell divides into 2 daughter cells

Slide 4

Binary Fission of Bacterial Cell

Binary Fission of Bacterial Cell

Slide 5

E. Coli Dividing by Binary Fission

E. Coli Dividing by Binary Fission

Slide 6

Eukaryotes

Eukaryotes

Contain a nucleus & membrane bound organelles

Asexually reproduce cells by mitosis

Slide 7

Cell Cycle

Cell Cycle

Stages in growth & division

G1 Phase

S Phase

G2 Phase

M Phase

Cytokinesis

Slide 8

G1 Phase

G1 Phase

First growth stage

Cell increases in size

Cell prepares to copy its DNA

Slide 9

Synthesis Phase

Synthesis Phase

Copying of all of DNAs instructions

Chromosomes duplicated

Slide 10

G2 Phase

G2 Phase

Time between DNA synthesis & mitosis

Cell continues growing

Needed proteins produced

Slide 11

M Phase

M Phase

Cell growth & protein production stop

Cells energy used to make 2 daughter cells

Called mitosis or karyokinesis (nuclear division)

Slide 12

Life Cycle of a Cell

Life Cycle of a Cell

Mitosis is a cycle with no beginning or end.

Slide 13

Interphase  Resting Stage

Interphase Resting Stage

Cells carrying on normal activities

Chromosomes arent visible

Cell metabolism is occurring

Occurs before mitosis

Slide 14

Interphase

Interphase

Slide 15

Stages of Mitosis

Stages of Mitosis

Prophase
