In a Prokaryotic cell, these structures are the flagella.
The cytoskeleton provides structure and support to cells, helps with cell motility by facilitating movement within the cell, and plays a role in intracellular transport by aiding in the movement of organelles and molecules.
When a gas moves in and out of a cell it is called diffusion.
The circulation of the cytoplasm is called cytoplasmic streaming. It is a process in which cytoplasm flows around within the cell, aiding in the distribution of molecules and organelles. This movement is often driven by the cytoskeleton and motor proteins.
The phloem parenchyma cell contains a nucleus which helps in regulating its metabolic activities. These cells are involved in maintaining the osmotic pressure gradient within the sieve cell, aiding in the movement of sugars and nutrients in the phloem.
This type of movement is called simple diffusion.
Cilia are short, thin, hair-like projections found on the surface of some cells that wave in a coordinated back-and-forth movement. They are involved in various functions such as moving fluids over the cell surface or aiding in the movement of the cell itself.
The movement in and out of a cell is called active transport. Liquids inside cells contain different substances and there is movement in and out to maintain a proper balance of ions and molecules.
Microtubules are part of the cytoskeleton and are involved in intracellular transport by facilitating the movement of vesicles and organelles within the cell. They are not directly responsible for transport of materials into or out of the cell, but rather play a role in maintaining cell shape and aiding in cell division.
endocytosis
Cytoplasmic streaming helps distribute nutrients, organelles, and other cell components throughout the cell, aiding in cellular processes such as growth, development, and repair. It also helps in the movement of signaling molecules within the cell.
It is called passive diffusion.
Diffusion is the simplest movement.
