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.

∙ 15y agoA 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.

How can bubble wrap prevent convection?
The heated particles will move into the space were the bubbles are and stay there as they cannot escape for a bit. This will mean that the cup will stay warm as it will be sourrounded by captured heat energy.
