Q

What are vesicles?

A

small membrane bounded sacs within the cytoplasm

17
Q

What do vesicles do?

A

used to transport proteins or other substances in or out of the cell

18
Q

3 common types of vesicles…..

A

vacuoles, lysosomes, peroxisome

19
Q

What is a vacuole…

A

basic storage unit of the cell that can hold various compounds

20
Q

What is a lysosome?

A

contains digestive enzymes that can dispose cellular debris and worn down cell parts

21
Q

What is a peroxisome?

A

functions to ride the body of toxic components such as hydrogen peroxide. Also major sites of oxygen use and energy production (liver has a lot)

22
Q

What are mitochondria?

A

powerhouses of the cell, where ATP is produced

23
Q

Fold on mitochondria are called

A

cristae, were enzymes help convert super into ATP to power the cell

24
Q

What are microtubules?

A

cellular tracks tracks hat during mitosis form the mitotic spindle. The spindle helps organize and segregate chromosomes during cell devision

25
Q

What are centrosomes?

A

microtuble organizing centers that help to form and organize the mitotic spindle during mitosis

26
Q

What is the nucleus?

A

Double membrane with pores. Control center of cell.

27
Q

What is the nucleolus?

A

Small body in nucleus produces ribosomes that get moved to the cytoplasm to make cell proteins

28
Q

More then a few projections (flagella) are then called…

A

Cilia

29
Q

The flagella and cilia of what cells are largest?

A

Eukaryotic

30
Q

What are chloroplasts?

A

Organelles in plant cells that contain chlorophyll.

31
Q

What does chlorophyll do?

A

Allows the capture of sunlight to be used for production of glucose during photosynthesis

32
Q

Plant cells have much larger _______ then eukaryotic cells.

A

Vacuoles that contain water

33
Q

Plant cells have a ________ cell wall.

A

Solid
