Study Notes

Cell Morphology

Prokaryotic and eukaryotic cells are the two main types of cells in terms of morphology.
Prokaryotic cells lack a nucleus and other membrane-bound organelles, while eukaryotic cells have both.

Reproduction in Prokaryotes

Prokaryotic cells reproduce asexually through binary fission.

Structural Differences Between Prokaryotes and Eukaryotes

A nucleus is absent in prokaryotic cells but present in eukaryotic cells.

Nomenclature in Microbiology

The scientific naming of microorganisms is known as taxonomy.

Bacterial Cell Wall Function

The primary function of the bacterial cell wall is to provide structural support and protect the cell from osmotic pressure.

Classifying Bacteria

Eukaryotic bacteria are characterized by the presence of a nucleus, which is not a feature of bacteria.
All bacteria possess a cell wall.

Bacterial Cytoplasmic Membrane

The cytoplasmic membrane in bacterial cells is composed of a phospholipid bilayer.

Purpose of the Bacterial Cell Wall

The bacterial cell wall plays a crucial role in maintaining the cell's shape and preventing lysis in hypotonic environments.
