Protists

What types of cells are these?

Plant

What type of cell is this?

Animal cell

What type of cell is this?

Light microscope

A microscope where visible light is passed through a specimen and then through glass lenses

Scanning electron microscope

A microscope where an electron beam is used to study the surface details of a cell or other specimens

Transmission electron microscope

A microscope that uses an electron beam to study the internal structure of thinly sectioned specimens

Robert Hooke

The person who first identified cells in 1665 by using an early compound microscope by looking at a thin slice of cork (plant material)

Anton van Leeuwenhoek

A person who observed a sample of pond water using a single lens (simple) microscope

Schleiden in 1838

Came to the conclusion that plants are made of cells

Schwann in 1839

Came to the conclusion that animals are made of cells

Virchow in 1855

Came to the conclusion that cells come from pre-existing cells

1. All living things are composed of cells

2. Cells are the basic units of structure and function

3. New cells are produced from existing cells

What are the three parts of the cell theory?

SA/V ratio

The ratio where cells need a surface area large enough to service volume of cell

Are surrounded by a barrier called the cell membrane and at some point contain DNA

What are two things all cells have

Prokaryote

A type of cell that has no nucleus present, no membrane-bound organelles, is smaller in size, has a simple form. Ex: bacteria

Eukaryote

A type of cell that has a nucleus, has membrane-bound organelles, is larger in size, is more complex. Ex: plants, animals, fungi, protists
