It has no energy required |
Passive |
|
|
It has energy required |
Active |
|
|
What are the 3 types of Passive |
Diffusion Osmosis Facilitated Diffusion |
|
|
The net movement of substance from an area of higher concentration to an area of lower concentration |
Diffusion |
|
|
A form of passive transport where water molecules move from low solute concentration (high water concentration) to high solute or low water concentration across membrane that is not permeable to the solute |
Osmosis |
|
|
What are the 3 types of Osmosis |
Hypotonic Solution Isotonic Solution Hypertonic Solution |
|
|
Concentration gradient formed by the solute -there is a net movement of water from the solution into the body -it will birst of swell if there 's may water |
Hypotonic Solution |
|
|
It has the same level of solute -no net movement of water will take place |
Isotonic solution |
|
|
It has high solute concentration and low water concentration -The net movement of water will be out of the body and into the solution |
Hypertonic Solution |
|
|
Exerted by the cell liquid |
Turgor Pressure |
|
|
Move into the cell by osmosis - The pressure exerted by the osmotic flow of wated |
Turgidity |
|
|
The process of contraction or shrinkage of the protoplasn of a plant cell and is caused due to the loss of water in the cell |
Plasmolysis |
|
|
What are the two types of transport proteins |
Channel Proteins Carrier Proteins |
|
|
It is the hallway for solute - It is to transport the ions and water molecules quickly through the membrane |
Channel proteins |
|
|
Two kinds of Channel Proteins |
Open-leak Channel Closed-gated Channel |
|
|
Only the big molecules can enter & it requires energy to move substances against their concentration gradients |
Carrier Proteins |
|
|
It is the movement of molecules or ions across a cell membrane from low to high concentration against the concentration gradients - has energy required
|
Active Transport |
|
|
It is a type of cellular transport in which substances such as ions and molecules move down their respective concentration gradients - no energy required |
Passive transport |
|
|
What are the two types of active transport |
Exocytosis Endocytosis |
|
|
Releasing contents outside the cell -removing waste of toxins |
exocytosis |
|
|
Cellular process in which substances are brought into the cell |
Endocytosis |
|
|
2 types of endocytosis |
phagocytosis pinocytosis
|
|
|
cellular eating |
phagocytosis |
|
|
cellular drinking |
pinocytosis |
|
|
Occuring inside the cell |
Intracellular |
|
|
occuring outside the cell |
Extracellular |
|
|
It is the passive movement of molecules along the concentration gradient |
Faciliated Diffusion |
|
|
Process of Osmosis in Animal cells |
Lysed - normal - shriveled |
|
|
Process of Osmosis in Plant cells |
Teigud - Flaccid - Plasmolyzed |
