Cell parts/ organelles to their functions

Question 1

Plasma Membrane

Answer 1

Controls what enters and leaves the cell (selective permeability)

Question 2

Nuclear Envelope

Answer 2

surrounds the nucleus and controls what enters and leaves the nucleus

Question 3

nucleus

Answer 3

the cell command center, contains the chromosomes and the nucleolus

Question 4

nucleolus

Answer 4

makes ribosomes

Question 5

cytoplasm

Answer 5

the jelly like fluid that fills a cell

Question 6

mitochondrion

Answer 6

the place where cellular respiration happens

Question 7

Endoplasmic reticulum

Answer 7

Transports molecules throughout the cell

Question 8

Golgi apparatus

Answer 8

Packages molecules and prepares them to be used in the cell or released from the cell in vesicles

Question 9

Ribosome

Answer 9

The place where proteins are assembled during translation

Question 10

Vacuole

Answer 10

A storage depot in the cell for water, minerals, and other molecules

Question 11

Lysosome

Answer 11

Contain digestive enzymes to break down molecules, old cell parts, or pathogens. “Garbage disposals of the cell”

Question 12

Peroxisome

Answer 12

Small sacks which help detoxify (they contain peroxidase and catalase enzymes to break down hydrogen peroxide produced by working cells)

Question 13

Cytoskeleton

Answer 13

Protein filaments that provides shape for a cell and anchors the organelles

Question 14

Centriole

Answer 14

Aid in cell division in animal cells by assembling and breaking down the spindle fibers

Question 15

Cilium

Answer 15

Small, hairlike organelles of motion

Question 16

Flagellum

Answer 16

Long, whip-like organelles of motion

Question 17

Microvilli

Answer 17

Microscopic fingerlike projections on the surface of a cell that increase the cells surface area

Question 18

Desmosomes

Answer 18

Connections that stick 2 cells together - like 2 spots stuck together with Velcro

Question 19

Gap Junctions

Answer 19

Connections between cells that create a tunnel between the two cells – so materials flow back and forth inside the 2 cells

Question 20

Tight Junctions

Answer 20

Connections that seal up the membranes between 2 cells completely – they are locked together (good for forming barriers such as in the lining of the intestine)

Question 21

METABOLISM

Answer 21

All of the chemical reactions that occur in the cells of the body

Question 22

CATABOLISM

Answer 22

Those reactions that break down large molecules into smaller molecules and release energy

Question 23

ANABOLISM

Answer 23

Those reactions (such as dehydration synthesis) that join simple molecules together to build more complex molecules and use up energy
