The potential energy of organic molecules is most readily available to cells in the form of?
Glucose is the energy that is locked inside an organic molecule most readily accessible in.
What is a double walled with molecules that have hydrophobic tails and hydrophilic head It is found in all cells and it controls what enters and leaves the cell?
Cell membranes composed of phospholipids
What is the chemical biological relevance of polar molecules?
our cells are surrounded by a cell membrane that is a lipid bilayer. this means that the hydrophilic heads, like water, are pointed towards the inside of the cell and the cells' exteriors. this allows polar molecules to move through the membrane and be dissolved within the membrane. the hydrophobic tails of this lipic bilayer are pointed towards eachother. these cannot be in contact with water or nothing will dissolve or be able to pass through them. O==O, the circles are the hydrophilic heads and the lines are the hydrophobic tails.
Which substances readily diffuse through the membrane?
Small and non-polar molecules can readily pass through the cell membrane. They follow the concentration gradient, moving from the higher concentration area to the region of lower concentration.
What are the features of xylem cell?
Xylem is the vascular tissue responsible for the transport of water and nutrients from the roots in the soil to the above-ground parts of the plant. Hormones and other small molecules also travel through the xylem as they are moved throughout the plant.Xylem are just made up from cell walls left from cells, making hollow tubes. The walls of these tubes are hydrophilic, so water attaches readily to them, helping it to climb on its way up the plant.

Are cells hollow?
Yes xylem cells are hollow because Xylem are just made up from cell walls left from cells, making hollow tubes. The walls of these tubes are hydrophilic, so water attaches readily to them, helping it to climb on its way up the plant

Why can small cells exchange substance readily than large cells?
why can small cells exchange substances more readily than large cells?
Why are older bacterial cells more easily decolorized than younger colonies?
OIder bacteria cells are decolorized more easily than younger cells, because as cells age their cell walls become "leaky" and allow molecules to pass more readily out of the cell. In gram stain, the crystal violet-iodine complex is more readily lost during the decolorization step.

Do plants have molecules?
yes they do they have cells that have molecules
How do some molecules get into cells?
Some molecules get into cells by going through their permeable membrane.
What is diffusion in cells?
diffusion- passive transport in cells where molecules move from an area where there are more molecules to an area of fewer molecules.
