Question 1

Nucleus

Answer 1

Contains the cell’s genetic material

Question 2

Nucleolus

Answer 2

Site of ribosome synthesis

Question 3

Smooth Endoplasmic Reticulum

Answer 3

Site of lipid synthesis and drug detoxification

Question 4

Rough Endoplasmic Reticulum

Answer 4

Site of protein folding and transport to Golgi apparatus

Question 5

Ribosome

Answer 5

Site of protein synthesis; found in cytoplasm and attached to Rough ER

Question 6

Golgi apparatus

Answer 6

Site of protein packaging and distribution

Question 7

Centrioles

Answer 7

Involved in cell division; makes spindle fibers

Question 8

Lysosome

Answer 8

vesicle that digests cell materials and waste; originates from Golgi

Question 9

Peroxisome

Answer 9

vesicle that contains catalase; originates from ER

Question 10

Mitochondria

Answer 10

produces ATP via cellular respiration

Question 11

Cilia

Answer 11

short protein extensions that sweep material across the cell surface

Question 12

Flagella

Answer 12

long, whip-like extension that functions in locomotion

Question 13

Cytoskeleton

Answer 13

structural proteins that provide framework for the cell

Question 14

Inclusions

Answer 14

stores products of a cell, such as fat droplets, pigment granules, or glycogen

Question 15

Microfilaments

Answer 15

actin and myosin protein subunits involved in movement and contractions

Question 16

Intermediate filaments

Answer 16

protein subunits involved in maintaining cell structure; forms desmosomes

Question 17

Microtubules

Answer 17

made of protein tubulin; maintains cell structure, involved in intracellular transport, forms mitotic spindle
