[Eukaryote] Animal and Plant cell differences

Here are differences between Plant and Animal cell: Cell Wall (not found in animal cell) This is rigid strong outer layer that protects cell from osmosis (bursting) and supports the cell by maintaining the shape. In prokaryotes, it is often made out of peptidoglycan In eukaryotes, (fungi, plants) it is often made out of cellulose … Continue reading [Eukaryote] Animal and Plant cell differences

Eukaryotic cell components

Here are basic cell components of eukaryotes:   All cells have: (also found in Prokaryotes) Cell Wall (not found in animal cell) This is rigid strong outer layer that protects cell from osmosis (bursting) and supports the cell by maintaining the shape. In prokaryotes, it is often made out of peptidoglycan In eukaryotes, (fungi, plants) … Continue reading Eukaryotic cell components

Prokaryotic cell components

Usually prokaryotes are unicellular (but not always). Although microbes are commonly unicellular, these grow in colony and some types of bacteria can form biofilm that enhances their survival. Note: word "cyto" - refers to "cell", a word originated from Greek. (Dictionarycom.) Here are the basic cell components of prokaryotes: All cells have: (also found in … Continue reading Prokaryotic cell components

What is Microbiology

Microbiology is the study of interaction between microorganisms and their surroundings, such as humans, animals, plants and our environment. (Belisle) Microorganisms also known as microbes, which are very small organisms that are often too small to be seen with naked eye. Some examples are bacteria, viruses, single celled eukaryotes etc.┬áThere are also some microorganisms that … Continue reading What is Microbiology

Peptidoglycan synthesis

Cell wall (Peptidoglycan synthesis) PG synthesis is important because: - To provide cell wall structure for protecting the cell from cell lysis (burst) due to high osmotic pressure - To provide cell wall structure to maintain the shape of cell - To replace old/matured or spliced PG during cell division For details, refer to: Peptidoglycan … Continue reading Peptidoglycan synthesis

Peptidoglycan structure and function

Peptidoglycan Bacterial cell wall is composed of peptidoglycan (also called murein) - Peptid -> peptide chains - oglycan -> polysaccharide Gram Negative Cell wall structure - Blue: outer membrane - Pink: Peptidoglycan (safranin - pink after gram staining) - Big white box: cell (cytoplasmic membrane) - green: lipopolysaccharide (LPS) - orange: lipoprotein - small white … Continue reading Peptidoglycan structure and function
