Parts of a Cell

Question 1

Plasma Membrane

Answer 1

The protective layer around the cell that lets some things in and out (think of a fence)

Question 2

Cytoplasm

Answer 2

The watery stuff in the cell that everything is floating in

Question 3

Ribosomes

Answer 3

small grains floating in the cell; this is where proteins are made

Question 4

Nucleus

Answer 4

The “brain” of the cell; contains the DNA; is surrounded by the nuclear membrane

Question 5

DNA

Answer 5

contains all the genetic information; the long name is deoxyribonucleic acid

Question 6

Chromosome

Answer 6

there are 23 pairs (46 total) in each nucleus; contains the DNA

Question 7

Rough endoplasmic reticulum (rough ER)

Answer 7

folded pathways covered with ribosomes where new proteins are made

Question 8

Smooth endoplasmic reticulum (smooth ER)

Answer 8

where the transport vesicles are made

Question 9

Transport vesicles

Answer 9

used to move things around the cell

Question 10

Golgi apparatus

Answer 10

where stuff is packaged to be transported (think of a UPS store or a post office)

Question 11

Lysosomes

Answer 11

where stuff the cell doesn’t need is broken down; these also kill bacteria (think of a landfill)

Question 12

Vacuoles

Answer 12

large storage sacs

Question 13

Vesicles

Answer 13

small storage sacs

Question 14

Mitochondria

Answer 14

the “power” station of the cell–where ATP is made by breaking enzymes down into sugars used for energy

Question 15

ATP

Answer 15

used for energy for the cell; made in the mitochondria
