The shrinking of animal cells ( hypertonic)

crenation

The shrinking of the plant cell membrane under hypertonic conditions

Plasmolysis

The bursting of the cell wall under hypotonic conditions

Cytolysis

What transpirts proteins on a molecular level?

Transport proteins

Taking materials in through pockets of cell membrane

Endocytosis

Taking in a large particle

Phagocytosis

Taking in liquids in endocytosis

Pinocytosis

Sending material out of the cell

Exocytosis

What are some examples of how single cells maintain homeostasis?

grow, respond to the environment, obtain energy, reproduce, transport molecules(O2, H2O, CO2), respond to temp. changes, etc.

cells are uniquely suited to preform functions within an organism for the good of all cells

Cell specialization

Factory Cells(specialized cell): what do they do? Give examples of organelles within and body cells?

-they contain a large amount of protein synthesizing organelles


-ER, Golgi apparatus, ribosomes


-Pancreas cells, liver cells, stomach lining cells

Light sensitive(specialized cell): what does it do? What does rhodopsin do? Give an example of what contains light sensitive cells?

-lower portion of cells contain a large amount of mitochondria; upper portion of cells contain flattened membranes called disks with a pigment called rhodopsin


-rhodopsin absorbs light and signals to cell


i.e. eyes

Street sweeper(specialized cell);

releases a mixture of water, carbohydrates, and salts called mucus to trap dirt particles; other cells have cilia to sweep these particles away to keep passageways open

Mobile cells(specialized cell):

pollen grains are suited with tiny wings to carry themselves in the wind for fertalization

How do cells communicate?

through chemical signals passed from cell to cell

chemical signals from communication cause the cell to...

speed up or slow down cell activities

Where are cellular junctions? What are two of their functions?

--between cells


-some junctions help cells to be held together


-other cellular junctions allow the chemical molecules to pass directly from one cell to the next

What do cells use to respond to communication?

receptors

What are receptors?

molecular structures to which the signaling molecule can bind

Where are receptors?

on cell membrane or in cytoplasm

What can receptors do?

cause changes in cellular activities
