They substances transported by blood.Gases,Nutrients,Water,Hormones,Urea,Ammonia,Other waste materials etc.
Cells enter mitosis to reproduce and grow more cells.
roots
materials enter and leave the nucleus through openings in its cell wall and membrane
12sperm cells
Raw materials and harmful wastes enter and exit the cells in your body by blood, the red blood carry oxygen from lungs to the body cells.

Dudley Castle did have a moat, built by Lord Edward Kinnley in 1234. But it is now covered over and filled in, you can see part of the moat before you enter the Barbican.
Chloroplasts contain bundles of thylakoids in most plant cells.
A moat of cells.
Materials can enter and leave the cell more easily and quickly, and the membrane can stretch and the cell expand to accomodate larger amounts of storage product. This is expecially seen in fat cells.
The water-filled trench around a castle is called a moat.
Living cells maintain homoeostasis by controlling materials that enter and leave the cell. This is made possible through the permeable cell membrane which is selective on the substances that pass through it.
Yes materials made inside of the nucleus such as ribosomes must leave
Lipids and proteins are the building materials of cells.
I think that the 'trench' you are thinking of is a moat. You could say that it is a trench full of water that surrounds the castle. If you are not thinking of a moat then I am sorry.
gradients are an example. Electric gradients are controlled by the transport of Na+ and K+ and H+, etc.
