Q

Prophase

A

Nucleolus and nuclear membrane disappear; chromatin condenses in to chromosomes; centrioles moves to opposite poles; spindle fibers attach to centromeres of cromatids

Q

Mitochondria

A

Make ATP via aerobic cellular respiration

17
Q

Ribosomes

A

Site of protein synthesis

18
Q

Rough Endoplasmic Reticulum (RER)

A

Processes and transports proteins made at attached ribosomes; synthesizes phospholipids

19
Q

Smooth Endoplasmic Reticulum ( SER)

A

Fatty acid and steroid synthesis; detoxifies toxic substances

20
Q

Golgi Complex

A

Receives and modifies proteins from RER; sorts and transports them

21
Q

Secretory Vesicles

A

Secretes substances outside the cell by exocytosis

22
Q

Lysosomes

A

Enzymes digest and recycle worn out organelles and substances entering the cells; can digest the cell

23
Q

Peroxisomes

A

Produce hydrogen peroxide; detoxify harmful substances

24
Q

Cytoskeleton

A

Three kinds of protein filaments; maintain cell shape and involved in cell movement and movement of organelles

25
Q

Centrosomes (centrioles)

A

Form mitotic spindle; needed to form cilia and flagella

26
Q

Cilia

A

Abundant, hair-like cell projections that move fluids and particles along the cell surface

27
Q

Flagella

A

Long cell projections; whip-like motion moves sperm
