Biology In Focus Chapter 4

Front 1

Prokaryotic Cells

Back 1

Cells without membrane-bound organelles. Bacteria and Archaea.

Front 2

Eukaryotic Cells

Back 2

Has membrane-bound organelles

Front 3

What do plant cells have that animal cells do not?

Back 3

A cell wall made of cellulose, chloroplasts, and central vacuoles

Front 4

What do animal cells have that plants do not?

Back 4

Lysosomes, microvili, and plants do not typically have flagellum or need for a cytoskeleton

Front 5

ATP is?

Back 5

Potentially the most important form of energy in biology. Formed by the mitochondria.

Front 6

How do animal cells keep their structure?

Back 6

Cytoskeletons and extra-cellular matrix

Front 7

How do plant cells keep their structure?

Back 7

Cell wall and water stored in central vacuoles pushes on the plasma membrane

Front 8

What does the cell wall do?

Back 8

Provide structure for plant cells

Front 9

What do choloroplasts do?

Back 9

Using photosynthesis, chloroplasts create an energy source for plants.

Front 10

Which 2 organelles have their own DNA and have 2 membranes each?

Back 10

Mitochondria and chloroplasts

Front 11

Function of central vacuoles?

Back 11

Take up most of the plant cell for water storage

Front 12

Function of lysosomes?

Back 12

It's low pH makes it acidic and it contains digestive enzymes

Front 13

Function of cytoplasm?

Back 13

Contains the organelles and absorbs shock from movement

Front 14

Function of the nucleus?

Back 14

Contains DNA information, nucleolus, and centrioles. Also pulls apart chromosomes during replication.

Front 15

What do Ribosomes do?

Back 15

Create protein

Front 16

Characteristics of Rough Endoplasmic Reticulum?

Back 16

Has ribosomes on it which produce protein

Front 17

Function of Smooth Endoplasmic Reticulum?

Back 17

A cell's pharmacy. Creates drugs and toxins.

Front 18

Mitochondria is responsible for?

Back 18

Cellular respiration and making ATP

Front 19

What does the Golgi Apparatus do?

Back 19

It's the UPS of the cell. Takes in particles, modifies them, and transports them out

Front 20

Peroxisomes have an important function. What is it?

Back 20

To neutralize peroxide

Front 21

What are flagellum for?

Back 21

Movement

Front 22

The most efficient cells are?

Back 22

Small cells, due to their high surface area to volume ratio

Front 23

How do microvili affect surface area?

Back 23

Microvili increase surface area

Front 24

What is an extra-cellular matrix?

Back 24

It's like a spider web that provides stability and structure for cells
