Biology - Cell and cell cycle

Stem cell

Type of cell that makes itself specialized to grow the body

All living organisms are made up of 1 or more cells

Cell theory 1

The cell is the basic unit of life

Cell theory 2

All cells come from preexisting eggs

Cell theory 3

Prophase(1st stage)

Chromatin(DNA) become chromosomes(double copy)

Nucleus starts to break down

Centrosomes start to form and spindle fibers from the centrosomes

Metaphase(2nd stage)

Sister chromatids line up in the middle of the cell

Centrosomes move to the two opposite sides of the cell perpendicular to the sister chromatids

Spindle fibers form out and attach to the centromeres

Anaphase(3rd stage)

Chromosomes are pulled apart by spindle fibers into individual sister chromatids

Telophase(4th stage)

Nucleus in each cell begins to reform(nuclear membrane, nucleus, etc…)

Single copy chromatids(DNA) start to unwind back into chromatin(spaghetti)

Two daughter cells begin to form

Cytokinesis(final stage)

The other organelles of the cell that are not the nucleus are divided among both cells to be fully regenerated in their individual daughter cells

Chloroplasts and cell walls

What is organelles do plant cells have that animal cell do not?

Centrioles, centrosomes and lysosomes

What organelles do animal cells have that plant cells do not?
