What are the 3 types of cellular extensions?

The types are: 1. Cilia and Flagella 2. Pseudopodia 3. Microvilli.

What types of cellular extensions are there?

Terms in this set (5)

  • Cilia. -are whiplike, motile extensions on surfaces of certain cells (such as respiratory cells)
  • Flagella. longer extensions that propel the whole cell (example: tail of sperm)
  • Cilia and Flagella.
  • Microvilli.
  • Cellular extension.

What are cellular extensions?

The cellular extensions of a neuron are called axons and dendrites and they transmit electrical impulses between neurons and from neurons to other cells of the nervous system. A neuron usually receives electrical impulses through its dendrites and it transmits them to other cells via its axon.

Which cell extension can move the cell?

Flagella
Flagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena). When present, the cell has just one flagellum or a few flagella.

What cellular extension increases absorption?

microvilli
Cells may have slender extensions of the cell membrane to form cilia or the smaller extensions called microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions.

What is cell membrane extensions?

The cytoskeleton is able to form appendage-like organelles, such as cilia, which are microtubule-based extensions covered by the cell membrane, and filopodia, which are actin-based extensions.

What is the name of the long cellular extension?

The discovery of long cellular extensions called cytonemes was intriguing because it suggested a novel means of cell communication within the disc (Ramirez-Weber and Kornberg, 1999).

What helps the cell move?

The cytoskeleton is the component of the cell that makes cell movement possible. This network of fibers is spread throughout the cell’s cytoplasm and holds organelles in their proper place. Cytoskeleton fibers also move cells from one location to another in a fashion that resembles crawling.

Which cellular extensions can increase the surface area?

Cells may have slender extensions of the cell membrane to form cilia or the smaller extensions called microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions.

What is another cellular extension which is often confused with cilia that increases the surface area for absorption eg of nutrients in the digestive system?

Microvilli function as the primary surface of nutrient absorption in the gastrointestinal tract.
