BSC 1005 Lecture Notes - Lecture 4: Cell Membrane, Lipid Bilayer, Micrometer
Document Summary
Bacteria, archaea: organelles comparable to eukaryotic cells are absents, organelles: membrane-bound structures with a specific function, dna is coiled into a nucleoid region. The blue is the dna in the nucleoid region with no defined nucleus, the outside is the plasma membrane and the inside of the capsule is the cytoplasm. Sometimes bacteria have an extra membrane called a cell wall. On the outside of the cell wall there are capsules. The long hair-like structure coming out of the cell is known as flagellum which helps the bacteria cells to move. The smaller hair-like structures are known as pilus, and help with getting the cell attached to the surface. Ribosome is a small round body that are inside the cytoplasm and involved in the synthesis of protein: eukaryotic cells, the dna is organized and contained within the nucleus, eu=true, different membrane-bound organelles are present, ex. Animal cell (heterotroph: defining features of eukaryotic cells, 1.
