Cell Organelles

Question 1

Nucleus

Answer 1

headquarters of cell + control center

Question 2

Nucleolus

Answer 2

makes ribosomes (involved in making proteins)

Question 3

Nuclear envolope

Answer 3

double membrane

Question 4

Chromatin

Answer 4

DNA in a non-dividing cell

Question 5

Nuclear pores

Answer 5

passageway for ribosomes to leave nucleus

Question 6

Ribosome

Answer 6

makes proteins (building blocks: amino acid)

Question 7

ER (endoplasmic reticulum)

Answer 7

houses ribosomes

Question 8

Smooth ER

Answer 8

“detoxifier of the cell”; takes out alcohol + makes lipids (fats); liver has most smooth er

Question 9

Golgi Apparatus

Answer 9

“pancakes of the cell”; inspects proteins made in cell; packages/secretes in the cell

Question 10

Mitochondria

Answer 10

“powerhouse of the cell”; makes ATP; muscles + liver have the most mitochondria

Question 11

Lysosomes

Answer 11

“garbage collector”; filled with enzymes to digest cell garbage

Question 12

Perioxosomes

Answer 12

converts H2O2 (hydrogen peroxide) to H2O

Question 13

Cytoskeleton

Answer 13

guides organelles in movement; gives cells structure

Question 14

Microfilament

Answer 14

made of protein (actin)

Question 15

Intermediate filaments

Answer 15

proteins (actin + myosin)

Question 16

Microtubules

Answer 16

made up of tubulin (protein)

Question 17

Cholesterol

Answer 17

helps to keep membrane flexible

Question 18

Enzymes

Answer 18

peripheral proteins

Question 19

Channel protein

Answer 19

integral protein; carry types of ions in/out of cell

Question 20

Cell identity protein

Answer 20

glyco protein; helps to detect “self”

Question 21

Cell membrane

Answer 21

Head: phosphate (hydrophilic)
Tail: phospholipid (hydrophobic)
