Unit 3 - Chapter 2 - Cell Membranes & Organelles
Movement of substances from a high concentration to a low concentration
Movement of water across a membrane from an area of high concentration to low concentration.
Passive movement across a membrane that requires specific carrier molecules.
Carrier mediated transport
Proteins embedded in cell membranes that assist transport across the membrane.
Bulk transport of fluids across a cell membrane.
Movement of substances across the membrane, out of a cell.
Bulk transport of substances across a membrane, into a cell.
Solids that are engulfed by a vacuole.
The control centre of the cell containing DNA, where the genetic information is stored.
A double membrane-bound organelle where respiration occurs.
Membrane bound organelle where proteins are packaged and exported.
A membrane bound organelle in cells containing digestive enzymes.
Rough Endoplasmic Reticulum
A membrane-bound organelle with ribosomes which transports
Organelle in plant cells containing chlorophyll where photosynthesis occurs.
Respiration requiring oxygen; occurring in mitochondria.
Respiration without oxygen.
Adenosine triphosphate molecule that stores energy.
Adenosine diphosphate molecule, product of energy release.
Liquid medium of a chloroplast.
Part of a chloroplast
Stack of thykaloids - part of a chloroplast.
a protein makes a tunnel in membrane and ions move across the channels from high concentration to low concentration
Same concentration inside and outside the cell
Solution has a lower concentration of salts/sugars, so water tends to move into the cell, causing an increase in size and mass.
The solution has a greater concentration of salts/sugars, so water tends to move out of the cell, causing it to lose mass and shrivel.
