Why don't flower pigments dissolve when they become wet with rain?
Because the pigments are contained inside cells. The cell walls separate the contents of the cell from the wet rain on the outside - you will notice that the underside of the flower does not get wet - well the surface of the top side is waterproof - this is caused by the protection of the cell walls.
What are the opposite ends of a cell called?
They are called poles, for example in anaphase chromosomes are pulled to the opposite poles of the cell.
2 examples of partially permeable membranes?
A selectively permeable membrane is most often attributed to the cell membrane (plasma membrane) of cells. It is constructed of nonpolar phospholipids that will not dissolve many substances, like ions or large molecules. There are carrier proteins embedded in the membrane that allow only certain substances through.
What characteristics of cell membranes may explain why fat soluble substances such as chloroform and ether rapidly affect cells?
The fact that cell membranes are semi-permiable creates openings for the substances to enter.

What is Tough material found in the cell walls of all fungi?
material found in the cell walls of all fungi
Where is the cell wall inside a cell?
Inside the molecule that contains cell walls.
What is the structure that transport substances in a cell?
VesiclesCell walls are the small structure. This is what transports the substances.
Where are cells walls found?
the cell wall is around the inside of a plant cell. hope i helped :D
Where is the cell membrane in the cells that have cell walls?
The cell membrane is found just inside under the cell wall in plant cells, which are the cells with cell walls Animal cells do not have cell walls.

What make up the tough fibrous cell walls of the plant?
Cellulose
Where is the cell membrane located for cells that have cell walls?
just inside the wall
What controles the movement in and out of the cell?
Inside of a cell it is the cell membrane which lets substances pass into the cell, and out. The cell wall is used to keep the shape of the cell the same.
What cell is inside the cell wall?
In plant cells, which contain cell walls, there is a cell membrane inside the cell wall. Inside the membrane is the cytoplasm which holds all the cell's vital organelles.
Where is cytoplasm found at?
cytoplasm is found inside a cell, just inside the cell walls. It contains all of the parts of a cell (except the nucleus ).
