Cell Biology

Question 1

Nucleus

Answer 1

Contains most of a cells DNA. This DNA instructs the production of protein.

Question 2

Nucleolus

Answer 2

Synthesizes Ribosomes

Question 3

Nuclear Membrane

Answer 3

Double Lipid Layer separating the nuclear connects from the rest of the cell

Question 4

Nuclear Membrane Pore

Answer 4

Holes that allow ribosomes and RNA to exit the nucleus

Question 5

DNA

Answer 5

Genetic Chemical passed from parent to offspring

Question 6

Ribosomes

Answer 6

Assemble Amino Acids in a particular order to make a certain type of protein

Question 7

Endoplasmic Reticulum

Answer 7

-Transports materials through its system of channels
-Synthesizes lipid membranes

Question 8

Golgi Body

Answer 8

Packages substances like protein inside of a vesicular and ‘tags” the vesicular with “an address”

Question 9

Mitochondria

Answer 9

-Site of cellular respiration
-Food energy (nutrient) is converted to nucleic acid to ATP

Question 10

Chloroplast

Answer 10

-Site of Photosynthesis
-Solar energy is converted into the chemical energy of glucose

Question 11

Cytoskeleton

Answer 11

System of proteins that gives structure and support to the cell

Question 12

Centrioles

Answer 12

Parried organelles that assist with cell division

Question 13

Vacuoles

Answer 13

Storage

Question 14

Vesicles

Answer 14

Lipid membrane pouches that are produced by the Golgi Body

Question 15

Lysosomes

Answer 15

Breaks down old worn out cell parts

Question 16

Cell (plasma) Membrane

Answer 16

Double Lipid Layer enclosing all of the cell organelles and cytoplasm

Question 17

Cell Wall

Answer 17

Rigid Wall outside of the cell membrane, gives support, shape, and protection

Question 18

Cytoplasm

Answer 18

-Mostly fluid in which the organelles are suspended
-Site of many chemical reactions

Question 19

Cell Theory 1

Answer 19

All Living Things are made of one or more cells

Question 20

Cell Theory 2

Answer 20

Cells are the basic unit of structure and function in all living things

Question 21

Cell Theory 3

Answer 21

Cells come from pre-existing cells

Question 22

Diffusion

Answer 22

The movement of substances from high to low concentration until equilibrium established. No ATP needed

Question 23

Osmosis

Answer 23

The diffusion of water through the use of a membrane protein

Question 24

Facilitated Diffusion

Answer 24

Diffusion of substances across the membrane with the help of a membrane protein

Question 25

Protein Pumps

Answer 25

Moving Substances from high to low to high concentration using a membrane protein. This requires ATP energy

Question 26

Endocytosis

Answer 26

Moving substances into a cell by forming a vesicle around them. This requires ATP energy

Question 27

Excocytosis

Answer 27

Substances exiting the cell from a vesicle. The vesicle fuses with the membrane and the vesicle ejects its contents outward. This requires ATP energy
