Cell Structure

Question 0

Microvilli

Answer 0

Folds of the plasma membrane that increase the surface area of the cell to increase absorption or secretion

Question 1

Nucleus

Answer 1

Contains DNA molecules and nucleolus

Question 2

Nucleolus

Answer 2

Assembly site for ribosomes

Question 3

Plasma Membrane

Answer 3

Controls movement of substances into and out of the cell

Question 4

Chromatin

Answer 4

Long thin strands within nucleus. Each strand composed of one DNA molecule and associated proteins

Question 5

Cytoplasm

Answer 5

Area of the cell that includes the cytosol and organelles

Question 6

Flagella

Answer 6

Long cell projection; whip-like motion moves sperm

Question 7

Cytosol

Answer 7

Fluid portion of cytoplasm that surrounds organelles

Question 8

Peroxisomes

Answer 8

Produce hydrogen peroxide; detoxify harmful substances

Question 9

mitchochondria

Answer 9

Makes ATP via aerobic cellular respiration

Question 10

Ribosomes

Answer 10

Site of protein synthesis

Question 11

Rough Endoplasmic Reticulum

Answer 11

Processes and transports proteins made at attached ribosomes; synthesizes phospholipids

Question 12

Smooth Endoplasmic Reticulum

Answer 12

Fatty acid and steroid synthesis; detoxifies toxic substances

Question 13

Lysosomes

Answer 13

Enzymes digest and recycle worn-out organelles and substances entering the cell; can digest the cell

Question 14

Secretory Vesicles

Answer 14

Secrete substances outside the cell by exocytosis

Question 15

Cytoskeleton

Answer 15

Three kinds of protein filaments; maintain cell shape and involved in cell movement and movement of organelles

Question 16

Golgi Complex

Answer 16

Receives and modifies proteins from RER; sorts and transports them

Question 17

Centrosomes

Answer 17

Form mitotic spindle; needed to form cilia and flagella

Question 18

Cilia

Answer 18

Abundant hair-like cell projections that move fluids and particles along the cell surface
