Answer 8

proteins

Question 9

What are flagella?

eukaryotic cells

Question 11

Describe the ER…

Answer 11

tubular transport network, looks like a stack of flattened membranous sacs.

Question 12

What is the difference between smooth and rough ER?

Answer 12

rough ER is studded with ribosomes

Question 13

Smooth ER is important for…

Answer 13

numerous metabolic processes in the cell

Question 14

The ER does what?

Answer 14

moves proteins from one part of a cell to another and to the outside of the cell (secretion)

Question 15

What does the golgi apparatus do?

Answer 15

packaging and transport of proteins. works hand in hand with ER. sorts and prepares proteins for transport

Question 16

What are vesicles?

Answer 16

small membrane bounded sacs within the cytoplasm

Question 17

What do vesicles do?

Answer 17

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

Question 18

3 common types of vesicles…..

Answer 18

vacuoles, lysosomes, peroxisome

Question 19

What is a vacuole…

Answer 19

basic storage unit of the cell that can hold various compounds

Question 20

What is a lysosome?

Answer 20

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

Question 21

What is a peroxisome?

Answer 21

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)

Question 22

What are mitochondria?

Answer 22

powerhouses of the cell, where ATP is produced

Question 23

Fold on mitochondria are called

Answer 23

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

Question 24

What are microtubules?

Answer 24

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

Question 25

What are centrosomes?

Answer 25

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

Question 26

What is the nucleus?

Answer 26

Double membrane with pores. Control center of cell.

Question 27

What is the nucleolus?

Answer 27

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

Question 28

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

Answer 28

Cilia

Question 29

The flagella and cilia of what cells are largest?

Answer 29

Eukaryotic

What are chloroplasts?

Answer 30

Organelles in plant cells that contain chlorophyll.

Question 31

What does chlorophyll do?

Answer 31

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

Question 32

Plant cells have much larger _______ then eukaryotic cells.

Answer 32

Vacuoles that contain water

Question 33

Plant cells have a ________ cell wall.

Answer 33

Solid
