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.
The cell membrane exhibits selective permeability, allowing it to control which substances can enter and exit the cell. This characteristic is primarily due to its phospholipid bilayer structure, which is embedded with proteins that facilitate transport. Small, nonpolar molecules can easily pass through, while larger or charged substances require specific transport proteins or channels. This selective control is essential for maintaining homeostasis within the cell.
A small space or cavity within the cytoplasm of a cell is called a vacuole. Vacuoles are membrane-bound organelles that can store various substances such as water, nutrients, and waste products. They play a crucial role in maintaining cell structure and function.
A vesicle is an organelle. It is a small, membrane-bound sac that transports and stores substances within a cell. Vesicles are involved in various cellular processes, such as secretion, transport, and storage of molecules.
Molecules embedded within the lipid bilayer that help substances cross the membrane include proteins such as channel proteins and carrier proteins. Channel proteins facilitate the passage of ions and small molecules through pores, while carrier proteins undergo conformational changes to transport specific substances across the membrane. Additionally, glycoproteins and glycolipids play roles in cell recognition and signaling, further assisting in the transport and communication of substances.

VesiclesCell walls are the small structure. This is what transports the substances.
A small spherical phospholipid bilayer (for polar substances) or monolayer (for hydrophobic substances). They also have embedded, enclosing or attached proteins for targeting, structure and transport.
