Slide 1: 

Cell Structure Flashcards

Slide 2: 

1. All living things are made of one or more cells 2. Cells are the basic unit of every living organism 3. Cells only come from pre-existing cells This is the…

Slide 3: 

Cell Theory

Slide 4: 

Cells without membrane bound organelles such as bacteria Are known as….

Slide 5: 

Prokaryotes

Slide 6: 

They don’t grow They don’t require energy They don’t maintain homeostasis And they’re not made of cells! They don’t reproduce…

Slide 7: 

Viruses

Slide 8: 

Swine Flu Virus The protein coat surrounding the DNA or RNA is called a…

Slide 9: 

Swine Flu Virus Capsid

Slide 10: 

Which stage of Viral infection produces dying cells and millions of viruses?

Slide 11: 

The Lytic Cycle

Slide 12: 

What do retroviruses like AIDS have that regular viruses do not?

Slide 13: 

RNA instead of DNA

Chloroplast

Responsible for homeostasis, it decides what enters and leaves the cell:

Cilia

Watery interior of the cell: 

Watery interior of the cell

Slide 46: 

The movement of substances in, into, and out of the cell Nerve cell

Slide 47: 

Cell Transport Nerve cell

Slide 48: 

Maintaining a constant internal environment

Slide 49: 

HOMEOSTASIS

Slide 50: 

Which organelle Maintains homeostasis?

Slide 51: 

The Plasma Membrane

Slide 52: 

The two ways that cells maintain homeostasis :

Slide 53: 

Passive Transport Active Transport )

Slide 54: 

The main component of the plasma membrane - polar heads attract water, fatty tails repel water - making a “sandwich”

Slide 55: 

Phospholipid bilayer

Slide 56: 

Passive Transport #1 the movement of particles from an area of high concentration to low

Slide 57: 

Diffusion

Slide 58: 

Passive Transport #2 Diffusion made easier by the use of proteins (transport proteins)

Slide 59: 

Facilitated Diffusion

Slide 60: 

Passive Transport #3 The movement of water across the membrane from high water concentration to low

Slide 61: 

Osmosis

Slide 62: 

This type of solution will cause a cell to swell up if placed into it:

Slide 63: 

Hypotonic

Slide 64: 

Active Transport #1 When cells “eat” substances by surrounding and engulfing them

Slide 65: 

Endocytosis

Slide 66: 

White blood cells are masters of endocytosis

Slide 67: 

Active Transport Active transport #2 Releasing large particles through openings in the plasma membrane - the opposite of endocytosis

Slide 68: 

Active Transport Exocytosis

Slide 69: 

Active Transport The end
