What else can I help you with?
What is a cell wall for?
It keeps the cell "guts" in and other stuff out. The cell wall also acts as a transport system to move nutrients and needed molecules in and waste products out of the cell.
What structure holds the cell together?
The cell membrane is the structure that holds the cell together. It acts as a barrier between the cell's interior and its surrounding environment, allowing for selective transport of molecules in and out of the cell. Additionally, the cell membrane is involved in cell signaling and communication with neighboring cells.
How do products of the cell get out of the cell?
Diffusion, facilitated diffusion, passive transport, facilitated transport (?) and active transport ... unless we are referring to viral or bacterial products.
Transport proteins and cholesterol are embedded in this structure?
The Cell Membrane
These structure are passageways from the nucleus that transport proteins through the cell?
cell membrane
What part of a cell is a sac that stores excretory or secretory products?
The part of a cell that acts as a sac to store excretory or secretory products is called a vesicle. Vesicles are small membrane-bound sacs that transport and contain various substances within the cell, including proteins, lipids, and waste products. They play a crucial role in processes such as secretion, metabolism, and cell signaling.
Which structure in the cell membrane acts as a door controls what enters and leaves a cell?
Cell membrane
Which structure in the cell membrane acts as a door and controls what enters and leaves a cell?
Cell membrane
What is the structure that transport substances in a cell?
VesiclesCell walls are the small structure. This is what transports the substances.
Structure regulates the transport in and out of the cell?
The cell membrane is the structure that regulates the transport of molecules in and out of the cell. It is selectively permeable, allowing certain substances to pass through while restricting others. Transport proteins embedded in the membrane help facilitate the movement of specific molecules across the membrane.
What is the thin layer around the cell that acts like a gate for the cell?
The cell wall. This structure is made up of a phospholipid bilayer and is studded with transport proteins that help pump molecules in and out of the cell. Many molecules are small enough to pass through the cell wall unaided by these proteins.
Transport membranes and products to various locations in cell?
Vesicles, small membrane-bound structures, transport substances such as proteins and lipids to different places within the cell. This intracellular transport is essential for maintaining cell function and structure. Transport vesicles move along microtubules and actin filaments to deliver their cargo to specific destinations within the cell.
