What is the role of diffusion within a cell?
Diffusion is an intermingling of molecules, ions, etc., resulting from random thermal agitation, as in the dispersion of a vapor in air. When there is a higher concentration of oxygen molecules outside the cell than inside the cell, diffusion takes place by causing the concentration of oxygen molecules to be the same outside and inside the cell.
What takes place in plant cell?
photosynthesis takes place in plant cells
Where within the cell does the process of respiration take place?
Respiration takes place in the mitochondria of a cell. The mitochondria are often referred to as the powerhouse of the cell because they are responsible for producing ATP, the cell's main source of energy, through the process of respiration.
What type of cell division takes place in the ganads?
Meiotic cell division takes place in the gonads in order to produce sex cells.
What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins
Where does diffusion takes place?
In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.
What is the thin cell covering through which diffusion takes place?
cell membrane
What kind of diffution takes place when plant cell absorbs water?
The plant cell absorbs water by simple diffusion and osmosis.
Where in animals does diffusion take place?
Diffusion happens in every plant and animal cell. It occurs through the membrane of each and every cell in the organism.
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
The cell does not need to expand energy ATP in order to perform what?
The cell does not need to expand ATP to perform passive transport processes such as diffusion or osmosis, where molecules move from areas of high concentration to low concentration without the need for energy input.
What are stomata and what are they?
exchange of gases takes place by simple diffusion directly into each cell through the openings present in epidermis called stomata. Stomata are found on the underside of leaves. :)
What is the role of diffusion within a cell?

When there is a higher concentration of oxygen molecules outside the cell than inside the cell, diffusion takes place by causing the concentration of oxygen molecules to be the same outside and inside the cell.
Are capillaries one cell thick?
They are one cell thick to allow diffusion of gases to take place
What takes place in plant cell?
photosynthesis takes place in plant cells
How is diffusion important to cell processes such as photosynthesis?
Diffusion is the process by which small particles move from a place of high concentration to a place of lower concentration. By diffusion, small molecules like salts can go inside a cell from the outside. To keep itself alive, a Cell needs to take in many things from its outside. In Photosynthesis, gaseous Carbon Dioxide (CO2) enters the plant cell by diffusion. CO2 is very important in building food and making energy for the plants.
Does photosynthesis take place in the cell membrane?
no it takes place in a plant cell with no cell membrane but a cell wall
