Cellular Organelles Overview
- What is the composition of a cell’s plasma membrane?
- List all the non-membrane-bound and all the membrane-bound cellular organelles in a eukaryotic cell.
- Composition of a Cell’s Plasma Membrane: The plasma membrane of a cell is primarily composed of:
- Phospholipid bilayer: Consisting of phospholipids arranged with hydrophilic (water-attracting) heads facing outward and hydrophobic (water-repelling) tails facing inward.
- Proteins: Integral proteins span the membrane, while peripheral proteins are attached to the membrane’s surface. These proteins serve various functions, including transport, signaling, and structural support.
- Cholesterol: Provides stability and regulates fluidity of the membrane.
- Glycolipids and glycoproteins: Involved in cell recognition and communication.
- Non-membrane-bound and Membrane-bound Cellular Organelles in a Eukaryotic Cell:
Non-membrane-bound organelles:
- Ribosomes: Sites of protein synthesis, found free in the cytoplasm or bound to the endoplasmic reticulum.
- Centrioles: Involved in organizing microtubules during cell division (present in animal cells)…
