Process by which a cell divides to form two new cells ( daughter cells)

Binary fission ( divided forming two new identical cells.

Which cell division where mitosis and meiosis?

Cell or organism growth & Replacement or repair of damaged cells

Formation of sex cells , or gametes

If cells grow without limit , an “information crisis” would develop

Food and oxygen have to cross membrane very quickly

DNA is copied, resulting in 2 identical chromosomes.

2 chromosomes separate , move towards ends (poles) of cell

Cytoplasm divides, forming 2 cells

Genetically identical to parent cell

Period of growth and DNA replication between cell division

Cell increases in size

Replication of chromosomes

Organelles double , New Cytoplasm forms , All other structures needed for mitosis form

DNA containing cell’s genetic code

Each chromosome has a matching pair

DNA found on chromosomes located in nucleus of cell

Cells grow, Dna replicated , Organelles duplicated, Divide to form daughter cells

Prophase , Metaphase, Anaphase, Telophase Nucleus Divides

Cytoplasm divide , forming 2 cells

Genetically to parent cell

Nuclear Division

Followed by cytokinesis (cell division)

Chromosomes visible (sister chromatids)

Centrioles migrate to the poles (only in animals)

Nuclear membrane disappears

The chromosomes appear condensed, and the nuclear envelope is not apparent.

Thick , coiled chromosomes are lined up in the center of the cell on the metaphase plate .

Spindle fibers are attached to the chromosomes.

The chromosomes have separated and are moving toward the poles

The chromosomes are at the poles , and are becoming more difuse.

The nuclear emvelope is reforming. The cytoplasm may be dividing .

(Eubacteria and Archaebacteria) Prokaryotes.

Eukaryotes, diverse , not fungi, plants, pr animals.

Eukaryotes, multicellular (except yeast)

Non-motile , aytotrophic , autotrophic, cell wall.

Motile , heterotrophic , no cell wall

The traditional five kingdom system

The six-kingdom system

Can cause endocarditis and dental caries

Spores can live in soil for years

On Plants and animals

Lichens and Mycorrhizae

Nonvascular plants

Vascular

Gymnosperms & Angiosperms

Wheat , grains , fruits , vegetables.

Aspirin , cancer treatments, stimulants

Agriculture, wood products, cotton

(97% of Animal Kingdom) Absence of backbone including worms and mollusks

Internal skeleton (bone or cartilage) includes fish , birds , and mammals
