Cell Boundaries

7.3 9/28/11

QuestionAnswer
Selectively Permeable Membranes Control_____________________. The "ease" at which substances pass in and out of the cell.
Cell Membrane acts like a _______ allowing membrane molecules to ______ Fluid Move
The Cell Membrane: Protects Cell Controls What Moves In & Out of Cell Helps Maintain Homeostasis
Cell Wall Can Be Found In: Bacteria,Plant,Fungi And SOME Protista
Substances are able to move within cells and across cell membrane through processes of ___________. passive & active transport
number of molecules or ions in one region is differant than the number in another is? Concentration Gradient.
Isotonic Equal concentration: solute concentration is equal inside and outside the cell.
Hypertonic Higher solute concentration outside the cell then inside of the cell. (Net movemnet of water outside the cell)
Hypotonic Higher solute concentration inside then outside the cell. (Net movement of water inside the cell).
Protein Channel Allows specific molecules to move across the cell membrane.
Facilitated Diffusion Is A Type Of Passive Transport_______________________. That does Not Require energy.
Active Transport: Requires Energy. Used to create a concentration gradient. Moves substances from low to high concentration.
Types of Endocytosis: Phagocytosis & Pinocytosis
Cell Wall Contains ____________, that are __________. Carbohydrates Structual Componet Cellulose.
Inside Of Cell Contains: Cytoplasm
Lipid Bilayer also known as ____________. Phospholipids.
Membrane Crossing Mechanisms: Diffusion Osmosis Active and Passive Transport Facilitated Diffusion.
Diffusion: Movement from area of high concentration to an area of low concentration.
Diffusion occurs until there is ________ amounts of solute spread throughout the sytem is known as ________________. Equal Equilibrium
Factors that affect the rate of diffusion include: Temperature: High temperature = faster diffusion. Steepness of Concentration: Steeper gradient = faster diffusion. Molecular Size: Smaller molecules = faster diffusion. Electrical or Pressure Gradients: Increase the rate of diffusion.
Characteristics of Osmosis: The movement of water across a selectively permeable membranes. Membrane prevents solutes from moving across membrane with water. Water moves to equaliza concentration inside and outside of the cell.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
