Every cell, whether it be a prokaryote, a eukaryote, plant, or animal, is enclosed by cell membrane (plasma membrane) created of a phospholipid bilayer. This membrane serves as to protect the cell as well as regulate objects going into and coming out of the cell. The cell membrane is created of various parts, and is commonly referred to with the fluid mosaic model. Embedded in the membrane are glycolipids and glycoproteins, which help with cell-to-cell interactions. Also in the membrane are transmembrane proteins, also known as protein channels. These channels regulate what diffuses in and out of the cell. In endocytosis, parts of the cellular membrane pinch off to form vesicles. This is the opposite of exocytosis, where the vesicles join with the cellular membrane and release waste.
In plant cells and prokaryotic organisms, the cell membrane is surrounded by a cell wall. This extra layer of cells serves as to stabilize the cell, as it is more stronger than the cell membrane.

ViviA cell is surrounded by its cell membrane, a thin "gatekeeper" that goes around the entire cell. An animal cell has a cell membrane, and a plant cell has a cell membrane and a cell wall, which is another layer of protection. In addition to the cell membrane and the cell wall, which are parts of the cells, there is an extracellular matrix which is made up of various proteins. A static cell, such as a liver cell that doesn't move, will have membrane proteins that are used to attach to this extracellular matrix. Some cells are just surrounded by more cells, such as the epithelial cells (skin cells, stomach cells, or any cells that act as a border). Additionally, the cell is surrounded by an aqueous environment (a requirement for all living cells). This aqueous environment is composed of mainly water; however, there are sugars, proteins, and other biological materials contained in the aqueous environment. The aqueous environment is required to sustain the transfer of materials into and out of the cell.

Plasma cells develop from transformed b cells or t cells?
Plasma cells develop from transformed B cells, specifically activated B cells that have undergone differentiation into plasma cells. T cells do not give rise to plasma cells.
What are some types of human cells?
Some types of human cells include red blood cells (erythrocytes), white blood cells (leukocytes), skin cells (keratinocytes), nerve cells (neurons), and muscle cells (myocytes).
What kind of cells are plant cells?
All plant cells are eukaryotic cells
How is animals cells different from plant cells?
Animal cells have lysosomes, plant cells don't. Plant cells have a cell wall made out of cellulose, animal cells don't. Animal cells have many small vacuoles, plant cells have one large vacuole. Plant cells have chloroplasts and chlorophyll, animal cells don't. Animal cells have centrioles, plant cells don't.
What are the differences in cell organelles between onion cells potato cells cheek cells and lettuce cells?
The difference between potato cells and onion cells, check cells, and lettuce cells is the presence of starch in the potato cells chloroplast organelles. The difference between cheek cells and the rest is easier the cheek cells do not have chloroplasts at all.
