Endocytosis is the process of a cell 'engulfing' material by foldings of the cell membrane.
Exocytosis is a process by which a cell releases large amounts of material. In this process a cell takes material into the cell by infolding of the cell membrane.
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.
The endocytosis process brings in large macromolecules and particles by the formation of a vesicle in the outer membrane. The two types of endocytosis are phagocytosis and pinocytosis.
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one

well that depends on how long or tall it is!
It is treated to remove any sediment and particles which will clog a membrane

The process by which the plasma membrane surrounds the substance inside the cell and moves it outside the cell is called EXOCYTOSIS.

The nuclear membrane, or more often called nuclear envelope, isolates a eukaryotic cell's chromatin(DNA) from the rest of the cytoplasm. The nuclear envelope is believed to have formed from the infolding of the cell membrane(basically the same process that also formed the endoplasmic reticulum). Unlike the cell membrane the nuclear envelope contains pores which are essential for the movement of mRNA from the nucleus out to the cytoplasm where ribosomes are located so protein synthesis can be undertaken.
