Watery materials which contains many of the materials involved in cell metabolism?
the cytoplasm.
What is the difference between osmolarity and tonicity?
Tonicity refers to the relative concentration of solute particles inside a cell, with respect to the concentration outside the cell. Osmolarity refers to the movement of water from the inside to the outside of a cell, and vice versa
When water leaves a plant cell the osmotic pressure will increase of decrease?
The osmotic pressure will decrease. The osmotic pressure is decreased because the water is leaving the cell.
What is movement of materials into and out of the cells is controlled by?
The cell membrane is the part of the cell that regulates what goes in and out of the cell. It is a very thin membrane containing the whole cell inside it. If you want to see a cell membrane, heres an easy project you can do. Materials 1 egg 1 jar (glass or plastic) Enough WHITE VINEGAR to fill the jar 1. pour the vinegar into the jar. 2. place the egg in the jar. 3. Wait for a few days. What happens is the eggs shell will dissolve, leaving the membrane exposed. The membrane is very sensitive, so don't apply too much pressure to the outside.
Watery material which contains may of the materials involved in cell metabolism?
cytoplasm
Does the cell membrane keep materials from entering or leaving the cell?
yes, the cell membrane does keep material from entering or leaving the cell -karla cruz 7th grade
What surrounds materials to be moved into or out of a cell?
a vacuole sorrounds any materials that are being taken out of the cell. they are made of lipids from the cell membrane if coming into the cell, or made of lipids from other organelles in the cell if leaving the cell
What is The process of substances leaving a cell called?
The process of substances leaving a cell is called diffusion. The cell membrane is a selective permeable membrane that only allows certain materials to enter or leave the cell.
Which term refers the movement of materials through a cell membrane without using the cell's energy?
active transport
Why is surface area an important factor in limiting factor in limiting cell growth?
The materials entering or leaving a cell need to pass through the cell surface.
What does exocytosis transport?
Exocytosis refers to the movement of materials out of the cell. It typically transports macromolecules, such as proteins, as well as the waste products of the cell.
Which term refers to the moventment of materials through a cell membrane without using the cells energy?
passive transport
Which term refers to the movement of materials through cell membrane without using the cells energy?
active transport
Which of the following is a characteristic of all of these extracellular structures?
They are constructed of materials that are largely synthesized in the cytoplasm and then transported out of the cell.
What materials do you need for an animal cell?
animal cell materials for a project
The cell membrane and water are both involved in what material?
The movement of materials into and out of the cell
Which part of a allows certain materials to enter the cell and other materials to exit the cell?
This part of the cell is refferred to as the cell 'membrane'
