What are the short hair-like projections on the surface of some cells?
Cilia, tail-like projections found on the surface of cells, are perhaps best known as molecular flippers that help cells move around.
Which of the following are small hair-like projections on the cell membrane?
Cilia are long, slender, hair-like projections found on nearly all of our cells. They are involved in a range of tasks, including cell proliferation, receiving sensory information, and communication between cells.
Which structures are hairlike projections on the cell surface?
These hair-like projections that extend from the cell membrane surface are not found on all cells. When they are present they can serve various functions. A centriole is a structure made up of nine groups of microtubules. They are found in pairs within animal cells and are located near the nucleus.
What structures are short hair-like projections emanating from the cell surface that aid in the movement of fluids along the cell surface?
Cilia and flagella. Cilia and flagella are motile, hair-like projections of the cell surface. They create currents in the surrounding fluid or movements of the cell to which they are attached, or both. There are two categories of cilia: single non-motile primary cilia and multiple motile cilia.
What are the small hair-like structure that serve a sensory function in eukaryotic cells?
Most eukaryotic cells possess one or more unique organelles known as cilia, membranated projections that regulate cell motility and environmental sensing, and serve important roles in human health and disease [1]. Cilia are commonly classified as nonmotile (primary) or motile.
What is the function of these hair-like structures?
Hair-like structures are prevalent throughout biology and frequently act to sense or alter interactions with an organism’s environment. The overall shape of a hair is simple: a long, filamentous object that protrudes from the surface of an organism.
Which of the following is a hair-like structure?
The correct answer is Cilia.
What is the hair-like structure in cell?
Tiny hairlike organelles called cilia cover many cells from single-celled microorganisms to mammalian tissue. Motile cilia beat actively generating cilia-driven flows.
What are short projections that help with movement?
Cilia are short projections from the cell surface that are filled along their length with microtubules. Sliding microtubules past one another provides a bending action that causes the whole cilia projection to change its shape.

What is small hair?
“Baby hairs” are the thin, wispy hairs that sometimes grow around your hairline. Also called “peach fuzz” or “vellus,” these hairs have a much different texture than the hair around the rest of your head. Despite their name, baby hairs often stay with you past adolescence and late into adulthood.
Is a short hair-like structure?
Cilia are short, hairlike structures that can move a cell or move molecules away from a cell. Most water in a cell is in the cytoplasm, a fluid that contains salts and other molecules. The cytoskeleton is made of a network of threadlike proteins that are joined to form a framework inside a cell.
