By what process do nitrates enter the cell?
Nitrates enter the cell through the process of active transport. Nitrates are essential for development of leaves of a plant and are absorbed through root hair cells.
Two difference between osmosis and diffusion?
1. higher concentration to lower concentration 2. through a semi-permeable membrane
How does a cell maintain differences in concentration of certain ions on either side of the plasma membrane?
Cells maintain unequal concentrations of ions on opposite sides of a cell membrane through active transport.
Can sundews absorb nitrates best through their roots or through their leaves?
Their leaves I think. Sundews grow in bogs where nitrates in the ground are in short supply, so basically they aren't as adapted in collecting nitrates through the soil. They adapted in order to obtain nitrates from else where. Insects that land on their leaves and are trapped by the sticky substance are digested for their nitrate intake.
How do nitrates enter plants?
Nitrogen fixing bacteria make nitrates available for plants to use.
How do nutrients flow through the membranes?
Mostly because of a difference in concentration between the intra- and extracellular space. Because of this, diffusion through a membrane occurs.
Do sundews absorb nitrates best through their roots or through their leaves?
Except for pygmy sundews, yes.
What is a plant's role in the nitrogen cycle?
Plants consume nitrogen in the form of Nitrates. Nitrogen gets converted into nitrates by the denitrifying bacteria. These plants absorb nitrogen in the form of nitrates through the groundwater.
Difference in osmosis and diffusion?
Diffusion is the spread of particles through random motion from regions of higher concentration to regions of lower concentration.... Osmosis is the net movement of solvent molecules through a partially permiable membrane into a region of higher solute concentration, in order to equalize the solute concentrations on the two sides....
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.
How does charge affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
Which solution might a cell maintain homeostasis through diffusion?
Diffusion allows waste chemicals to move down a concentration gradient. The chemicals will move from an area of high concentration (inside the cell) to areas of lower concentration (outside of the cell) via the cell membrane. This is also an example of passive transport.
