Answer 1

one or more cells

Question 2

Cells are the basic unit of structure and

Answer 2

function in all living things.
Cells → Tissue → Organs → Systems → Organism

Question 3

Cells come from

Answer 3

pre-existing cells

Question 4

Nucleus function:

Answer 4

Control center of the cell
Contains chromosomes (DNA)

Only eukaryotes

Answer 5

have nuclei

Question 6

Prokaryotes (bacteria)

Answer 6

don’t have nuclei

Question 7

parts of the nucleus

Answer 7

Nuclear envelope-
double membrane
Nuclear pore - regulates what goes in/out of the nucleus
Nucleolus - produces ribosomes

Question 8

Mitochondria function

Answer 8

Creates energy (ATP molecules) by process of cellular respiration

Question 9

Semi-autonomous

Answer 9

Contains its own DNA and ribosomes

Question 10

parts of the mitochondria

Answer 10

Cristae: folds of the inner membrane (increase surface area)
Matrix: Fluid inside

Question 11

Endoplasmic Reticulum function
Two types: Smooth (SER) and Rough (RER)

Answer 11

SER: makes lipids
RER: produces and
transports proteins

Question 12

Endoplasmic Reticulum parts

Answer 12

Lumen (storage
space inside ER)

Question 13

Ribosomes function

Answer 13

production of proteins (translation)

Question 14

ribosomes Two types:

Answer 14

Free ribosomes: found in cytoplasm
Bound ribosomes: attached to Rough Endoplasmic Reticulum

Question 15

Ribosomes parts

Answer 15

Made up of proteins
and rRNA

Question 16

Golgi apparatus function

Answer 16

packages and sends materials within the cell or outside the cell

Question 17

golgi apparatus parts

Answer 17

vesicles (tiny bubbles used to transport materials)

Question 18

lysosomes function

Answer 18

Contains digestive (acidic) enzymes
Helps in fighting disease
Breakdown and digests old/foreign material

Question 19

cytoskeleton functions

Answer 19

Holds cell structure
Transports materials

Question 20

cytoskeleton types

Answer 20

Microfilament (thinnest)
Microtubule (thickest)

Question 21

examples of cytoskeleton

Answer 21

cilia, flagella, centrioles

Question 22

cilia

Answer 22

small/numerous hair-like structures

Question 23

flagella

Answer 23

long/few tail-like structures used for movement

Question 24

centrioles

Answer 24

used for cell
division in animal cells

Question 25

All the organelles above are in both plant and animal cells. Organelles only found in plant cells are:

Answer 25

Chloroplast Vacuole Cell wall

Question 26

chloroplast function

Answer 26

Produces glucose for plants (photosynthesis)

Question 27

semi-autonomous:

Answer 27

Contains its own DNA and ribosomes

chloroplast parts

Answer 28

Thylakoid (pancake) Granum (stack of pancakes) Stroma (syrup)

Question 29

vacuole function

Answer 29

Stores water, food, amd wastes Can take up to 80% of cell’s volume (start off as several small vacuoles and later mature into one large vacuole)

Question 30

cell wall function

Answer 30

Keeps out harmful substances Prevents cell from bursting

Question 31

cell wall location

Answer 31

Outside the cell membrane of plant and bacteria cells
