Anatomy of Cell

Question 1

All animal cells have

Answer 1

Nucleus, plasma membrane & cytoplasm

Question 2

Chromatin

Answer 2

When cell is not dividing, the genetic material is loosely dispersed throughout nucleus in a threadlike form

Question 3

Chromosomes

Answer 3

When the cell is in the process of dividing to from daughter cells, the chromatin coils & condenses forming rod like bodies

Question 4

Nucleoli

Answer 4

Composed of proteins & ribonucleic acid (RNA)

Question 5

Ribosomes

Answer 5

Composed of RNA & protein; floating free or attached to a membranous structure ( rough ER) in the cytoplasm

Question 6

Rough ER

Answer 6

Studded w/ ribosomes; tubules of the rough ER provide an area for storage & transport of the proteins made on the the ribosomes of other cell areas

Question 7

Smooth ER

Answer 7

Is a site of steroid & lipid synthesis, lipid metabolism & drug detoxification

Question 8

Nucleus

Answer 8

Where ribosomes are madero

Contains genetic material & DNA

Question 9

Golgi Apparatus

Answer 9

Packing proteins or other substances fro export from the cell or incorporation into the plasma membrane & in packaging lysosomal enzymes
( where protein get shipped/package/modified)

Question 10

Lysosomes

Answer 10

Function to digest worn-out cell organelles & foreign substances that enter cell
( breaking stuff down)

Question 11

Peroxisomes

Answer 11

Containing oxidase enzymes that detoxify alcohol, free radicals & other harmful chemicals

Question 12

Mitochondria

Answer 12

Produce cellular energy (ATP)

Question 13

Centrioles

Answer 13

Direct the information of the mitotic spindle during cell division

Question 14

Transport Vesicle

Answer 14

Transport proteins/ carbohydrates & molecule

Question 15

Cytoskeletal

Answer 15

Provide cellular support; function in intracellular transport

Question 16

Microfilaments

Answer 16

Cell mobility

Question 17

Intermediate Filaments

Answer 17

Resist mechanical forces acting on cells

Question 18

Microtubules

Answer 18

Form the internal structure of the centrioles & help determine cell shape

Question 19

Microvilli

Answer 19

Increase the surface area of the cell available for absorption or passage and for the binding of signaling molecules

Question 20

Nuclear Envelope

Answer 20

The nucleus is bound by a double-layered porous membrane

Question 21

Nuclear Pore

Answer 21

They are spanned by protein complexes that regulate what passes through & they permit easy passage of protein & RNA molecules

Question 22

Plasma Membrane

Answer 22

Separates cell contents from the surrounding environment, providing a protective barrier

Question 23

Cytosol

Answer 23

The fluid cytoplasmic material
