Cell Structure

Question 1

What are characteristics of prokaryotes?

Answer 1

Are primitive cells, and only bacteria are formed from the lack of nucleus, and are membrane bound organelles. contain DNA and ribosomes in the cytoplasm and have a cell membrane and cell wall.

Question 2

What are the characteristics of eukaryotes?

Answer 2

They contain in nuclear cell membrane, ribosome, and membrane bound organelles, And are everything except bacteria

Question 3

What’s the function of the cell membrane?

Answer 3

A thin, flexible layer, which regulates movement of materials into and out of the cell

Question 4

What’s the function of cytoplasm?

Answer 4

Gel like substance, composed, primarily of water that contains dissolved gases in nutrients for chemical reactions and holds the organelles.

Question 5

What’s the function of the chromatin?

Answer 5

Contains DNA proteins which have been condensed, is found in non-dividing cells and is the form of DNA used for proteins synthesis

Question 6

What is the function of a chromosome?

Answer 6

Form after DNA replication and are further condensed. Only found in dividing cells. Proteins synthesis cannot occur when the DNA takes this form

Question 7

What is the function of cilia?

Answer 7

Short hair like, vibrating cellular projections they are found in large numbers on the surface of certain cells can cause currents in the surrounding fluid

Question 8

What is the function of flagella?

Answer 8

Slender, hair-like structures, which enables some microorganism and sperm to swim

Question 9

What’s the function of centrioles?

Answer 9

Rod like structures that help during cell division mitosis in most eukaryotic animal cells.

Question 10

What’s the function of the cytoskeleton

Answer 10

Protein fibers, which make up the cells, skeleton, provide structural support and moves organelles and vesicles throughout the cytoplasm.

Question 11

What are the function of organelles?

Answer 11

Organelles are subcellular structures that have one or more specific jobs to perform in the cell

Question 12

What’s the function of ribosomes?

Answer 12

This is the site of protein synthesis proteins can either be structural or functional. They are made of ribosomal RNA and proteins. They’re considered an organelle and are not membrane-bound.

Question 13

What’s the function of the nucleus?

Answer 13

Stores genetic material (DNA) and controls cellular activities

Question 14

What’s the function of the nucleoli’s?

Answer 14

Produces ribosomal RNA a sub unit of ribosomes

Question 15

What’s the function of the nucleoli’s?

Answer 15

Produces ribosomal RNA a sub unit of ribosomes

Question 16

What is the function of the rough endoplasmic reticulum?

Answer 16

Holds ribosomes that produce proteins and also stores and transports proteins within the cell

Question 17

What’s the function of the Golgi body apparatus?

Answer 17

Functions as a factory, and which proteins receipt from the ER or further process/modified and sorted for transport to the eventual destinations

Question 18

What’s the function of chloroplasts?

Answer 18

Produce energy through photosynthesis meaning they convert sunlight into food for the cell

Question 19

What is the function of the mitochondria?

Answer 19

Is the site of cellular respiration process which converts chemical energy of glucose into a useable form of energy this energy is called ATP.

Question 20

What is the function of a vacuole?

Answer 20

Our small, membrane-bound sacs store enzymes, nutrients and waste.

Question 21

What is the function of the vesicles?

Answer 21

Are small membrane-bound sacs used for the transport, export and storage of molecules.

Question 22

What is the function of a lysosome?

Answer 22

Are spherical vesicles, which contain hydrolytic Enzymes that can break down all kinds of biological molecules. They also act as the waste disposal system of the cell by digesting unwanted materials in the cytoplasm.
