What else can I help you with?
What controls the movement in and out of the cell in plant cells?
cell membrane aka plasma membrane
What contains cell materials?
The cell membrane, also known as the plasma membrane, contains cell materials and is responsible for controlling the passage of substances in and out of the cell. The cytoplasm, a jelly-like substance within the cell, contains various organelles where different cellular activities take place. And lastly, the nucleus, which is surrounded by a nuclear envelope, houses the cell's genetic material in the form of DNA.
Does water surround cells?
Yes, water surrounds cells and is essential for their structure and function. Water helps to maintain the shape of cells, facilitates chemical reactions within cells, and acts as a medium for transporting nutrients and waste products.
What are the 3 types of cellular transport that the plasma membrane controls?
There are many different processes that are controlled by the plasma membrane aka as the cell membrane.Selective Permeable -- this means that only certain things will be allowed to enter or to leave the cell membrane.Active transport -- this process is where ATP is required. An example of this type of transport is when there is particles that are too large to passively go through the membrane will need to be carried by glucose, and through protein carriers.Passive transport -- this is where no actual ATP is required, it flows quite freely through the membrane. One example of this type is diffusion.
What composes the primary structure of the Cell membrane?
The Cell membrane is primarily composed of a lipid bi-layer, two layers of lipids with the hydrophyllic {fatty acid} acid 'heads' on the bi-lateral external surfaces, while the bi-lateral hydrophobic 'fatty' tails co-exist happily on the interiorof the bi-lipid layer.Bacteria possess a protective Cellulosic Cell Wall exterior to their Cell membranes, while Eukaryotic Cells utilize a Glyco-Protein Cell Coat to accomplish the same Functions.The Cell membrane contains all of the Biochemically Active 'Trans-Membrane Proteins'.Be sure that the Composition, and Production, of both [of] the Cell Walls and the Cell Coats are Enzymatically Regulated [aka Controlled].
Phosopholipids and proteins are used to make the cells what?
The phospholipid bilayer, aka, the cell membrane.
What regulates what leaves a cell?
plasma membrane aka cell membrane
What regulates a passage of materials between the cell and its environment?
cell membrane aka plasma membrane
What controls the movement in and out of the cell in plant cells?
cell membrane aka plasma membrane
What regulates which substances enter and leave a cell?
The plasma membrane. Carrier proteins and ion channels are parts of the plasma membrane, and aid in diffusion across concentration gradients, as most things don't freely move from one end of the cell membrane to the other. The Sodium-Potassium pump is a major ion channel in the plasma membrane, and regulates the intake of potassium and export of sodium (3 molecules sodium out, 2 molecules potassium in.)

Is facilitated diffusion?
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane
When the cloud of plasma reaches the earth what is formed?
Aurora borealis (aka "Northern Lights")

Is it true that proteins at the inner surface of the plasma membrane attach the membrane to the cells support structure making the cell rigid?
The primary proteins of cellular structure (such as in microfilaments or intermediate tubules) is myosin and actin, and sometimes collagen, and all of these are proteins in the cell. Because proteins generally connect to similar structures (aka other proteins), and the cellular membrane must SOMEHOW be attached to the primary cell structure, and it is easier to connect to the inner membrane than outer, the answer is yes.
