Bacteria
This type of microscopic, single-celled organism is a prokaryote because it does not have a nucleus.

Animal cells, and Human cells
This man observed cork under his microscope and named the tiny, box-like structures "cells".
Robert Hooke
This part of the microscope is what you look through, usually containing a 10x magnification lens.
eyepiece
Unlike bacteria, these tiny infectious agents are not considered alive because they cannot reproduce without a host cell.
virus
What does Bacteria do
Bacteria are tiny, single-celled living organisms that break down food, recycle nutrients in nature, and support human health, though some types can cause disease
How many types of cells are there?
All living cells fall into two main types: prokaryotic cells and eukaryotic cells.
He discovered bacteria and protozoa, which he originally called "animalcules"
Anton van Leeuwenhoek
He is widely considered the "Father of Microbiology" for improving the microscope and being the first to observe bacteria.

He was the first scientist to note that all plants were made of cells.
Matthias Schleiden
This adjustable part of the microscope regulates the amount of light that passes through the stage and reaches the specimen

Unlike bacteria, viruses cannot reproduce on their own and require this type of organism or cell to replicate

Why do some Bacteria have tails?
Bacteria have tail-like structures called flagella so they can swim and move through liquids
What controls the cell?

Discovered in 2003, this gargantuan virus genus shattered previous size records and contains a double-stranded DNA genome larger than that of many bacteria
Mimivirus
What is the most Deadly Bacteria?
Mycobacterium tuberculosis is the deadliest single bacterial pathogen in human history
how many cells are in a human body
estimated 30 to 37 trillion cells
This fundamental biology concept states that all living things are composed of one or more cells, cells are the basic unit of life, and cells arise only from pre-existing cells.
The Cell Theory
Developed in 1893 to eliminate uneven glare, this precise method of aligning a microscope's optical elements acts as the gold standard for optimizing specimen illumination.
Köhler illumination
Discovered in 2020, this bizarre 30-nm circular virus found in human tissue samples completely baffled scientists because it possesses zero recognizable genes matching any known biological database.
