Cell Structure - Description - Function

Question 1

Plasma Membrane

Answer 1

The membrane at the boundary of every cell that acts as a selective barrier, regulating the cell’s chemical compostion.
FUNCTION
protect the cell from its surroundings and able to maintain homeostasis
(semi permeable barrier)

Question 2

Phospholipid

Answer 2

A lipid made up of glycerol joined to two fatty acids and a phosphate group. The hydrocarbon chains of the fatty acid act as nonpolar hydrophobic tails while the rest of molecule acts as a polar hydrophilic head. Function as biological membranes and form from bilayers

Question 3

Glycolipid

Answer 3

A protein with one or more covalently attached carbohydrates
FUNCTION
Recognition

Question 4

Glycoprotein

Answer 4

A protein with one or more covanetly attached carbohydrates
FUNCTION
Cell cell recognition

Question 5

Peripheral Protein

Answer 5

membrane proteins that adhere only temporarily to the biological membrane with which they are associated
FUNCTION
Transportation to various locations in the cell.

Question 6

Integral Protein

Answer 6

membrane protein that is permanently attached to the biological membrane
FUNCTION
Transporters

Question 7

Transport Protein

Answer 7

a protein that serves the function of moving other materials within an organism.

Question 8

Receptor Protein

Answer 8

the molecule to which the receptor binds

–>may be on the plasma membrane or within the cell

Question 9

Recognition Protein

Answer 9

proteins that are embedded in the cellular membrane the allow cells to communicate with each other.

Question 10

Adhesion Protein

Answer 10

proteins that hold cells together

Question 11

Nucleus

Answer 11

Atom’s central core containing protons and neutrons
The organelle of a eukaryotic cell that contains the genetic material in the form of chromosomes
FUNCTION
The nucleus controls and regulates the activities of the cell

Question 12

Nucleolus

Answer 12

A structure in nucleus consisting of chromosomal regions containing ribosomal RNA genes along with ribosomal proteins imported from the ctyoplasm
FUNCTION
makes ribosomal subunits from proteins and ribosomal RNA

Question 13

Nucleoid

Answer 13

A non membrane enclosed region in a prokaryotic cell where its chromosome is located
FUNCTION
Nucleoid is the part of cell which contains primary DNA material. It includes enzymes & proteins that transcribe RNA & DNA.

Answer 15

The portion of the endoplasmic reticulum with ribosomes attached
FUNCTION
function is to produce proteins.

Question 16

Smooth ER

Answer 16

The portion of the endoplasmic reticulum free of ribosomes
FUNCTION
make cellular products like hormones and lipids.

Question 17

Golgi Complex

Answer 17

(apparatus)
An organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify store and route products of the endoplasmic reticulum and synthesize some products notably noncellulose carbohydrates

Question 18

Lysosome

Answer 18

A membrane enclosed sac of hydrolytic enzymes found in the cytplasm of animal cells and some protists
