Packs up and ships out proteins "Amazon of the Cell"

Holds organelles in place "Jello"

Forms the cell's shape "Cell's skeleton"

Lipid bilayer that regulates what can enter and exit the cell "Cell Bouncer"

Stores water and nutrients inside of animal cells

Stores water, nutrients, and helps support the structure of a plant cell

Digests waste using enzymes (lipid membrane) "Garbage Man"

Makes ATP energy for the cell "Powerhouse of the Cell"

Provides a rigid, protective layer

Prokaryotic cells do not have ___________________.

Membrane-bound organelles (like a nucleus)

1. Cytoplasm 2. DNA 3. Ribosomes 4. Cell Membrane

What is the function of the cell membrane's phospholipid bilayer?

Allows certain molecules into and out of the cell "Semi-permeable"

Small molecules flowing from an area of high concentration to an area of low concentration across the cell membrane DOES NOT REQUIRE ENERGY

Facilitated Diffusion

Large molecules flowing from an area of high concentration to an area of low concentration using protein channels in the cell membrane DOES NOT REQUIRE ENERGY

The movement of water with the concentration gradient from an area of high concentration to an area of low concentration in order to reach equilibrium DOES NOT REQUIRE ENERGY

ATP is used to push molecules against the concentration gradient from an area of low concentration to high concentration USES ENERGY

Appears like science but is actually false Does not follow the scientific method

Explains what will happen in a given situation Does not change and cannot be disproven

Describes how the phenomenon happens Can be changed or disproven

3 Parts of Cell Theory

1. All living things are made up of one or more cells 2. Cells are the basic structure/unit of life 3. All cells are made from pre-existing cells

What 3 organelles are unique to plant cells?

1. Cell wall 2. Large central vacuole 3. Chloroplasts

What are plant and animal cells considered eukaryotic?

They both contain a nucleus and membrane-bound organelles

Why is it important that the cell membrane is flexible?

Cells can move, change shape, and fit through narrow spaces

Why is it important that cells are self-repairing?

Helps maintain homeostasis and prevents cell death

What is the function of protein channels?

Allows larger molecules into and out of the cell
