What is water uptake at the roots?
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient
Does chemiosmosis involve a concentration gradient?
Yes, chemiosmosis involves a concentration gradient. Think of chemiOSMOSIS, osmosis being the diffusion of water, which involves a concentration gradient.
What is a differences in concentration called?
concentration gradient
Net movement of water across a cell membrane occurs from what?
It depends on the concentration of the water. Through osmosis, water will move from a higher concentration to a lower concentration, or down a concentration gradient.
Do substances in diffussion move with the concentration gradient?
no. High concentration to low concentration. The molecules move down the concentration gradient.

What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
What isThe difference in concentration between a region of high concentration and one of lower concentration?
Regarded as existing through Space, or Time, or from one end of an aqueous Solution to the 'other'; these differences are seen to occur across a GRADIENT. In other related circumstances we are talking about a Spectrum.
What is osmosis diffusion?
(WATER CELLS ONLY)Water cells move from a higher concentration gradient (more water cells) to a lower concentration gradient (less water cells) through a partially permeable membrane (allows certain substances in and out) and goes with the concentration gradient (high -> low)
What are the two things needed for osmosis to take place?
Partially permeable membrane(visking tubing) and water
How does water leave a cell when in salt water?
Water moves according to an concentration gradient. Water potential gradient between two places
What is a differences in concentration called?
concentration gradient
What is osmosis gradient?
Osmosis is the diffusion of water across a water permeable membrane. The gradient is the tendency of the water molecules to move from the side of higher concentration of water to the side with lower concentration of water in an attempt to achieve equilibrium.
What is the term for the Diffusion of water across the concentration gradient?
Osmosis
Osmosis is defined as the movement of?
water across a concentration gradient
What is moving down the concentration gradient in all cells?
All small molecules can move down the concentration gradient as water O2, CO2 etc.
