Prokaryotic Cells

Cells without membrane-bound organelles. Bacteria and Archaea.

Eukaryotic Cells

Has membrane-bound organelles

What do plant cells have that animal cells do not?

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

What do animal cells have that plants do not?

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

ATP is?

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

How do animal cells keep their structure?

Cytoskeletons and extra-cellular matrix

How do plant cells keep their structure?

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

What does the cell wall do?

Provide structure for plant cells

What do choloroplasts do?

Using photosynthesis, chloroplasts create an energy source for plants.

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

Mitochondria and chloroplasts

Function of central vacuoles?

Take up most of the plant cell for water storage

Function of lysosomes?

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

Function of cytoplasm?

Contains the organelles and absorbs shock from movement

Function of the nucleus?

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

What do Ribosomes do?

Create protein

Characteristics of Rough Endoplasmic Reticulum?

Has ribosomes on it which produce protein

Function of Smooth Endoplasmic Reticulum?

A cell's pharmacy. Creates drugs and toxins.

Mitochondria is responsible for?

Cellular respiration and making ATP

What does the Golgi Apparatus do?

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

Peroxisomes have an important function. What is it?

To neutralize peroxide

What are flagellum for?

Movement

The most efficient cells are?

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

How do microvili affect surface area?

Microvili increase surface area

What is an extra-cellular matrix?

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