Transport Mech Cell

Passive and Active Transport Mechanism across Cell Membrane

TermDefinition
Diffusion, facilitated diffusion, Osmosis, and filtration are types of what kind of transport mechanisms? Passive transport mechanisms
Movement of a substance without help from an area of high concentration to an area of low concentration. Diffusion
Helper molecule within the cell membrane assist with movement of substances from area of high concentration to area of low concentration. Facilitated diffusion
Diffusion of water (solvent) from an area with more water to an area with less water. The water compartments are separated by a semipermeable membrane. Osmosis
The pushing of water and dissolved substances from an area of high pressure to an area of low pressure. The water and dissolved substances are pushed. Filtration
Transport mechanisms that requires an input of energy (ATP) is referred to as what type of transport mechanism? Active Transport Mechanisms
Moves a substance uphill (from an area of low concentration to an area of high concentration). Requires an input of energy (ATP) Active transport pump.
Is a transport mechanism that involves the intake of food or liquid by the cell membrane Endocytosis (In Endocytosis, the particle is too large to move across the membrane by diffusion. Instead, the particle is surrounded by the cell membrane, which engulfs it and take it into the cell).
What are the two forms of Endocytosis? Phagocytosis and Pinocytosis
Form of endocytosis. Engulfing of solid particles by the cell membrane (cellular eating). Phagocytosis (For example, white blood cells eat, or phagocytose, bacteria, thereby helping body defend itself against infections)
Form of endocytosis. Engulfing of liquid droplets (cellular drinking). Pinocytosis.
Is a transport mechanism that moves substances out of the cell, cellular products (e.g. protein, debris), out of the cell. Exocytosis.
Describes a solution that is more concentrated than the inside of a cell. Hypertonic
Solution that causes a red blood cell to swell with water and burst. Hypotonic

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.
