Cell Structures

Question 1

Contractile vacuole

Answer 1

Control water pressure within the cell

Question 2

Nucleus

Answer 2

The “control center of the cell” holds the cell’s main DNA

Question 3

Cell wall

Answer 3

A rigid structure on the outside of certain cells. Usually plant and bacteria cells

Question 4

Plasma Membrane

Answer 4

The semipermeable membrane between the cell contents and either cell wall or the cell’s surroundings

Question 5

Food Vacuole

Answer 5

Holds food while it’s being digested

Question 6

Phagocytic vacuole

Answer 6

Vacuole that engulfs large food substances

Question 7

Central vacuole

Answer 7

A large vacuole that rests at the center of most plant cels and is filled with a high concentration of solutes

Question 8

Chromoplasts

Answer 8

Organelles that contains pigments used in photosynthesis

Question 9

Rough Endoplasmic reticulum

Answer 9

ER that is dotted with ribosomes

Question 10

Centrioles

Answer 10

Organelles mostly found in animal cells; composed of micotubules
2 different functions:
Form flagella or cilia
Involved in asexual reproduction called mitosis

Question 11

Golgi bodies

Answer 11

Where proteins and lipids are stored and then modified to suit the needs of the cell

Question 12

Leucoplasts

Answer 12

Organelles that store starches or oils

Question 13

Nucleolus

Answer 13

The center where RNA is made. Ribosomes are also assembled there and transported out of the nucleus

Question 14

Chromatin

Answer 14

Clusters of DNA, RNA, and proteins in the nucleus of a cell

Question 15

Cytoskeleton

Answer 15

A network o fibers that holds the cell together, helps the cell keep its shape, and aids in movement

Question 16

Middle Lamella

Answer 16

The thin film between the cel walls of the adjacent plant cells

Question 17

Secretion vesicle

Answer 17

Vesicle that holds secretion products so that they can be transported to the plasma membrane and released

Question 18

Pinocytic vesicle

Answer 18

Vesicle formed at the plasma membrane to allow the absorption of large molecules

Question 19

Waste vacuole

Answer 19

Vacuoles that contain the waste products of digestion

Question 20

Smooth Endoplasmic Reticulum

Answer 20

ER that has no ribosomes

Question 21

Lysosome

Answer 21

Te organelle in animal cells responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides , and some lipids

Question 22

Cytoplasm

Answer 22

A jellylike fluid inside the cell in which the organelles are suspended

Question 23

Mitochondria

Answer 23

The organelles in which nutrients are converted to energy

Question 24

Ribosomes

Answer 24

Non-membrane-bounded organelles responsible for protein synthesis
