ANAPHY QUIZ REVIEW (CELL)

Question 1

Is the basic structural and functional units of life

Answer 1

Cell

Question 2

Is a fragile, transparent barrier that contains the cell contents and separates them from the surrounding environment

Answer 2

Plasma membrane

Question 3

Is often called the headquarters of cell and the “Control Center”

Answer 3

Nucleus

Question 4

are sites where cell structures called the ribosomes are produced

Answer 4

Nucleolus or nucleoli

Question 5

Its main function is to to compress and package long DNA molecules into compact, dense structures. The structure of it keeps DNA organized and prevents breakage

Answer 5

Chromatin

Question 6

Is the cellular material outside the nucleus and inside the plasma membrane. It is the site of most cellular activities

Answer 6

Cytoplasm

Question 7

Is a semi transparent fluid that suspends the other elements

Answer 7

Cytosol

Question 8

Are chemical substances that may or may not be present, depending on the specific cell type. They dtore nutrients or cell products floating in the cytosol

Answer 8

Inclusions

Question 9

Are specialized cellular compartments that are the metabolic machinery of the cell.

Answer 9

Organelles

Question 10

Are usually depicted as tine, beanlike or sausage-shaped organelles, but in living celles the lengthen and change shape almost continuously. They supply most of the ATP, they are the “powerhouse” of the cell

Answer 10

Mitochondria

Question 11

Actual sites of protein synthesis of the cell

Answer 11

Ribosomes

Question 12

Is a system fluid-filled tunnels that coil and twist through the cytoplasm. It provides a network of channels for carrying substances from one part of the cell to another.

Answer 12

Endoplasmic reticulum

Question 13

You cqn think of it as a cell’s membrane factory. It is specially abundant in cells that make(synthesize) and export(secrete) proteins.

Answer 13

Rough Endoplasmic reticulum

Question 14

It function in lipid metabolism and detoxification of drugs and pesticides

Answer 14

Smooth endoplasmic reticulum

Question 14

Its major function is to modify, package, and ship proteins in specific ways, depending on the destination.

Answer 14

Golgi apparatus

Question 15

Their most important function is to detoxify free radicals. Detoxify harmful or poisonous substances

Answer 15

Peroxisomes

Question 15

They’re best known for their role in generating microtubules and also for directing the formation of the mitotic spindle during spindle fibers

Answer 15

Centrioles

Question 16

Are whiplike cellular extensions along the cell surface

Answer 16

Cillia

Question 17

microscopic hair-like structures involved in the locomotion of a cell

Answer 17

Flagella

Question 18

Are tiny, fingerlike extensions of the plasma membrane that projects from an exposed cell surface. They increase the cell’s surface area tremendously and so are usually found on the surface of cells active in absorption

Answer 18

Microvilli

Question 19

An elaborate network of protein structures extend throughout. It acts cell’s bones and muscle by furnishing an internal framework that determines the cell shape, supports other organelles and provides the machinery for intracellular transport and various types of cellular movements.

Answer 19

Cytoskeleton

Question 20

Role in generating microtubules and also for directing the formation of mitotic spindle during cell division. They are rod shaped bodies that lie at right angles to each other

Answer 20

Centrioles

Question 21

Are impermeable junctions that encircle the cells and bind them together into leak-proof sheets.

Answer 21

Tight junctions

Question 22

Are anchoring junctions scattered like rivets along the sides of adjacent cells. They prevent cells subjected to mechanical stress from being pulled aapart

Answer 22

Desmosomes

Question 23

Its function mainly allow communication. These junctions are commonly found in the heart and between embryonic cells.

Answer 23

Gab junctions
