Prophase , Metaphase, Anaphase, Telophase Nucleus Divides

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

Agriculture, wood products, cotton

Gymnosperms & Angiosperms

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

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

DNA containing cell’s genetic code

On Plants and animals

Aspirin , cancer treatments, stimulants

Each chromosome has a matching pair

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

DNA found on chromosomes located in nucleus of cell

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

Nuclear membrane disappears

Which cell division where mitosis and meiosis?

(Eubacteria and Archaebacteria) Prokaryotes.

The six-kingdom system

Cytoplasm divide , forming 2 cells

Genetically identical to parent cell

Cytoplasm divides, forming 2 cells

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

The chromosomes have separated and are moving toward the poles

Centrioles migrate to the poles (only in animals)

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

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

Binary fission ( divided forming two new identical cells.

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

Wheat , grains , fruits , vegetables.

Non-motile , aytotrophic , autotrophic, cell wall.

Vascular

Followed by cytokinesis (cell division)

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

Cell increases in size

Spindle fibers are attached to the chromosomes.

Eukaryotes, multicellular (except yeast)

Nonvascular plants

Chromosomes visible (sister chromatids)

Cell or organism growth & Replacement or repair of damaged cells

Formation of sex cells , or gametes

Lichens and Mycorrhizae

Motile , heterotrophic , no cell wall

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

Period of growth and DNA replication between cell division

The traditional five kingdom system

DNA is copied, resulting in 2 identical chromosomes.

Food and oxygen have to cross membrane very quickly

Replication of chromosomes

Genetically to parent cell

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

Nuclear Division

Spores can live in soil for years

Can cause endocarditis and dental caries
