colloidal suspension that fills cell 

holds cell contents

large, dark-staining body near the center of the cell; composed of DNA and proteins

contains the chromosomes with the genes

small body in the nucleus; composed of RNA, DNA, and protein

needed for protein manufacture 

network of membranes in the cytoplasm 

used for storage and transport; holds ribosomes

small bodies attached to the ER; composed of RNA and protein

manufacture proteins

large organelles with folded membranes inside

convert energy from nutrients into ATP 

layers of membranes

put together special substances such as mucus 

short, hairlike projections from the cell

create movement around the cell

long, whiplike extension from the cell

moves the cell

• chromosomes condense and become visible
• spindle fibers emerge from the centrosomes
• nuclear envelope breaks down
• nucleolus disappears

• mitotic spindle is fully developed, centrosomes are at opposite poles of the cell
• chromosomes are lined up at the metaphase plate
• each sister chromatid is attached to a spindle fiber originating from opposite poles

• cohesin proteins binding the sister chromatids together break down
• sister chromatids (now called chromosomes) are pulled toward opposite poles
• non-kinetochore spindle fibers lengthen, elongating the cell

• chromosomes arrive at opposite poles and begin to decondenese
• nuclear envelope material surrounds each set of chromosomes
• the mitotic spindle breaks down
