What else can I help you with?
Why can oxygen diffuses across a cell membrane but Protein can not?
Its too large
When water diffuses into a plant cell and builds pressure?
tugor pressure
When water diffuses into a plant cell and builds up firm pressure that is called?
Turgor pressure. When the plant cell's central vacuole swells with water, the cell membrane pushes against the cell wall, creating this pressure that helps maintain cell shape and support the plant's structure.
What gas diffuses through cell membranes so that respiration can take place?
oxygen
What is the purpose of adding iodine solution to the onion cell?
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.
The water in a cell does what?
diffuses in and out of the cell
Why gram's iodine called a mordant?
Gram's iodine is called a mordant because it fixes the primary stain to the cell wall and adds any color.
'What is it called when water diffuses into a plant cell and builds up firm pressure?
This process is called turgor pressure. When water diffuses into a plant cell and fills the central vacuole, the cell swells and the pressure created against the cell wall is known as turgor pressure. Turgor pressure helps maintain the rigidity and structure of the plant cells, supporting the overall structure of the plant.
Why is iodine used as an antiseptic?
Simple answer is that it kills infections. It is poisonous in large concentrations (as found in direct application) but is actually beneficial in low concentrations. (as would happen when it diffuses through the body). Iodine deficiency is the cause of several thyroid abnormalities such as goutier. The main reason that iodine kills is that it sets up a concentration bias that will rupture bacterial cell-membranes.
What does lugol's iodine stain do to the activity of the cell?
I just did a lab in biology called "How Plant and Animal Cells Differ" and in the packet it had that question. The answer is: Lugol's iodine stain stops the activity of the cell. It kills whatever specimen it is staining.
Why does a cell diffuse items into the cell?
The cell needs food and water so it diffuses it to maintain health.
How do unicellular get water?
Water diffuses across their cell membranes
What is a cell plasma membrane?
the outer most part of the cell where items diffuse into the cell, and waste diffuses out of the cell to be disposed.
What molecule diffuses out of the pores of the leaf?
The molecule that diffuses out of the pores of the leaf is called water vapor.
Why can oxygen diffuses across a cell membrane but Protein can not?
Its too large
When water diffuses into a plant cell and builds pressure?
tugor pressure
In plant cell where diffusion occurs?
Gas exchange for photosynthesis - CO2 from the air diffuses into the leaf, and 02 diffuses out of the leaf into the air
