Study Notes

Microbiology Basics

Microbiology is the study of microorganisms, which are tiny, often single-celled organisms.
Microorganisms play crucial roles in various environments, including human health, ecology, and industry.

Prokaryotic Cells (Bacteria and Archaea)

Cell Wall: rigid, outermost layer that maintains cell shape and provides protection.
Plasma Membrane: semi-permeable membrane that regulates the flow of substances in and out of the cell.
Cytoplasm: jelly-like substance where metabolic processes occur.
Nucleoid: region where genetic material is found, but lacks a true nucleus.
Ribosomes: site of protein synthesis.
Flagella: whip-like structures used for movement.
Pili and Fimbriae: hair-like structures used for attachment and DNA transfer.
Plasmids: small, self-replicating circular DNA molecules that can be exchanged between cells.

Eukaryotic Cells (Fungi, Protozoa, Algae)

Cell Wall: varies in composition and function depending on the organism.
Plasma Membrane: similar to prokaryotic cells, regulates the flow of substances in and out of the cell.
Cytoplasm: similar to prokaryotic cells, where metabolic processes occur.
Nucleus: membrane-bound organelle that contains genetic material.
Ribosomes: site of protein synthesis.
Endoplasmic Reticulum (ER): network of membranous tubules and cisternae involved in protein synthesis and transport.
Golgi Apparatus: complex of flattened sacs and tubules involved in protein modification and transport.
Mitochondria: site of cellular respiration.
Chloroplasts (in algae): site of photosynthesis.
Lysosomes: membrane-bound organelles containing digestive enzymes.
Cytoskeleton: network of filaments that provides structural support and shape.

Key Functional Processes

Metabolism: conversion of energy and nutrients into cellular components.
Reproduction: process by which microorganisms produce new cells.
Genetic Variation: changes in genetic material that occur through mutation, gene transfer, and recombination.
Response to Environment: adaptation to changes in temperature, pH, and other environmental factors.
