Idea that: 1. ALL living things are composed of cells, 2. cells are the basic units of structure and function in living things, 3. new cells are produced from preexisting cells

very small simple cell that does NOT have a nucleus or other membrane-bound organelles ( Kingdoms Archaebacteria and Eubacteria)

Cell with a nucleus (surrounded by its own membrane) and other internal organelles ( Kingdoms: Fungi, Plantae, Protista, & Animalia)

Studied cork under the microscope and and named the structures he saw "cells", discovered cells, 1st to see cells

Dutch scientist who looked at teeth scrappings and pond water, called the organisms he saw "animicules", further advanced the microscope, 1st to see LIVING cells

German botanist who studied plant cells, he and Schwann contributed to cell theory by demonstrating that all living things are made of cells AND that cells are the basic structural unit of living things

German zoologist who studied animal cells, he and Schleiden contributed to cell theory by demonstrating that all living things are made of cells AND that cells are the basic structural unit of living things

A German doctor who stated that all living cells come from other living cells (part 3 of the cell theory)

a microscope that shines light through a specimen and has two lenses to magnify an image

A microscope that uses an electron beam to study the surface architecture of a cell or other specimen, expensive and requires training to operate

a microscope that passes an electron beam through very thin sections stained with metal atoms and is primarily used to study the internal structures of cells, expensive and requires training to operate

A part of the cell containing DNA and RNA and responsible for growth and reproduction, NOT FOUND IN PROKAYOTIC CELLS

ONLY eukaryotic cells have these, tiny organ like structures surrounded by a membrane

Made of a single cell, ALL prokaryotes are unicellular

organisms made of many cells, most eukaryotes are multicellular but many protists are not

have a cell membrane (plasma membrane), cytoplasm, DNA, and ribosomes

the MISTAKEN idea that living things arise from nonliving sources, in direct conflict with 3rd point of Cell Theory ( All cells come from preexisting cells)

Makes proteins, found in BOTH prokaryotes and eukaryotes

phospholipid bilayer that surrounds ALL cells and regulates what enters and leaves the cell

process in which a liquid is heated to a temperature that kills most bacteria and microorganisms to prevent spoiling of canned goods

located in the baseilluminates sample

Holds the microscope slide in position.

used to focus only on low power

Holds and turns the objectives into viewing position

Regulates the amount of light on the specimen

Contains a lens that magnifies about 10x

this part moves the stage slightly to help you sharpen or "fine" tune your view of the specimen

a small lens with low magnifying power (4x)

medium sized objective

a large lens with high magnifying power.

Used to support the microscope when carried

supports the microscope

Connects the eyepiece to the revolving nosepiece

holds the slide in place on the stage

objective lens x ocular (eyepiece) lens

a theory that states that certain kinds of prokaryotes began living inside of larger cells and evolved into the organelles of modern-day eukaryotes

strong, supporting layer around the cell membrane in plants, fungi, & prokaryotes, NOT found in animal cells
