What is it?

List the three parts of the Cell Theory.

1. All living things are made of cells.

2. Cells are the basic units of life.

3. All cells come from pre-existing cells.

What are the two basic types of cells?

Prokaryotes and Eukaryotes

Which type of cell has a nucleus?

Present your answers!

Eukaryote

This is the simpler of the two types of cells.

Prokaryotes

This type of cell has membrane-bound organelles.

Eukaryotic

______________ is the thin, flexible barrier around all cells.

Plasma membrane (Cell membrane)

The plasma membrane is made up of two layers of

______________.

Phospholipids

What are the two parts of a phospholipid called?

Head and a tail

These molecules are located in the hydrophobic region of the membrane and strengthen the

membrane.

Cholesterol

Scientists call the model they have developed to represent the

structure of the plasma membrane the ______ ________ model.

Fluid Mosaic

What does it mean to be selectively permeable?

To choose what goes in and what doesn’t

T or F. All cells have cell membranes.


True

T or F. All cells have DNA.


True

T or F. All cells have cytoplasm.


True

T or F. All cells have a nucleus.


False

T or F. All cells have a cell wall.

False – animal cells do not.

What is the name of the membrane that surrounds the

nucleus?

Nuclear envelope

What are the functions of the cytoskeleton?

For cell support and movement

The cytoskeleton is made up of what three components?


Microtubules, microfilaments, and intermediate filaments

What do ribosomes do for the cell?


Make proteins

Where can you find ribosomes in a cell?


On rough ER, and in the cytoplasm (also in the

nucleolus when they are being made

What are the two types of Endoplasmic reticulum and what

is the structural difference between the two types?


Smooth and Rough – rough have ribosomes attached

What does the ER do for the cell?

Rough – modifies proteins

Smooth – makes lipids and breaks down drugs and alcohol

What does the Golgi apparatus do for the cell?

Processes and packages proteins for export

What is the function of a lysosome?

To digest or break down food, old organelles, or other waste

What type of molecules are inside lysosomes? (These molecules are

what make the breaking down happen.)

Enzymes

What is the function of a central vacuole?

A place for plants to store water, minerals, and waste;

strengthens the cell and helps support the entire plant

What do chloroplasts do for the cell?

Convert energy from sunlight to chemical or food energy;

perform photosynthesis

Do animal cells have chloroplasts?


No

What is the function of the mitochondria?


To make energy (the power plant of the cell)
