A stoma is simply the space between two cells called guard cells.
The guard cells are specialized cells of the leaf's epidermis. The guard cells have unevenly thickened walls. When their vacuoles contain the maximum amount of water, turgor causes the cells to bend, leaving a space, the stoma, between them.
When the osmotic pressure falls, the cells partially collapse, like partly-deflated balloons, closing the stoma.
The variations in turgor in guard cells are brought about by varying concentrations of potassium ions in the cells.

How can cells regulate gene expression to control their functions and responses?
Cells can regulate gene expression by turning genes on or off, controlling the amount of proteins produced. This process helps cells control their functions and responses to different signals and environments.
The cellular junctions that join the cells of mammalian small intestine are what junction what junction and what?
The cellular junctions that join cells in the mammalian small intestine are called tight junctions. These junctions create a barrier that prevents substances from leaking between the cells and help regulate what passes through the intestinal lining.
How can cells regulate the diffusion of molecules through protein channels?
Cells can regulate the diffusion of molecules through protein channels by controlling the opening and closing of these channels. This regulation can be achieved through various mechanisms, such as changes in the cell's membrane potential or the binding of specific molecules to the channel proteins. By adjusting the activity of these channels, cells can selectively allow certain molecules to pass through while blocking others.
What gas passes from blood to body cells?
Oxygen is the gas that passes from the bloodstream to body cells through the process of oxygenation. Oxygen is essential for cellular respiration, which is the process that cells use to generate energy.
How do cells regulate enzymes?
Cells regulate enzymes through various mechanisms such as allosteric regulation, post-translational modifications (e.g. phosphorylation, acetylation), and gene expression control. Allosteric regulation involves molecules binding to specific sites on enzymes to alter their activity. Post-translational modifications can activate or inhibit enzymes by changing their structure or function. Gene expression control involves regulating the amount of enzyme produced by the cell.
How does your body regulate the amount of water you have in your cells?
you can poo all over yourself

they are called the cells

Which GTPases regulate intracellular transport in mammalian cells through vessicle fussion?
Rab
Do gases pass through your Capillaries?
Yah dummy. Oxygen passes into the cells from caps and Carbon Dioxide out of the cells into the caps
Which cancer treatments is designed to create ions as it passes through cells and tissues?
radiation
What cancer treatments is designed to create ions as it passes through cells and tissues?
radiation
Which GTPases regulate intracelluar transport in mammalian cells through vesical fusion?
Ran GTPases
What passes out through a cells membrane?
spelloids. its due to the hydroids acting with the rooids to make spelliods.

How do cells regulate synthesis to conserve energy?
Cells regulate synthesis by controlling the activation of enzymes involved in metabolic pathways. This is done through feedback inhibition, where the end product of a pathway inhibits the enzyme responsible for its synthesis. By regulating when and how much of a certain product is produced, cells can conserve energy by only making what is necessary for their immediate needs.
