History of the Cell• The Cell

–The basic unit of an organism–The discovery of the cell was made possible by the invention of the microscope.

Glue in your scientists!

Anton van Leeuwenhoek

Robert Hooke

Microscopes and Cells

• 1600’s- Anton van Leeuwenhoek first described living cells as seen through a simple microscope.

Microscopes and Cells–Robert Hooke used the first compound microscope to view thinly sliced cork cells.

• Compound scopes use a series of lenses to magnify in steps.• Hooke was the first to use the term “cell”.

Microscopes and Cells• 1830’s - Mathias Schleiden

identified the first plant cells and concluded that all plants are made of cells.

- Thomas Schwann made the same conclusion about animal cells.

Jot down some notes about Cell Theory on the back of your foldable as you listen

1. What discovery is Robert Hooke responsible for?

Robert Hooke observed empty spaces in a slice of cork and called them “cells”.

2. Who identified that all animals are made of cells?

Thomas Schwann concluded that all animals are made of animal cells.

Cell Theory1. All organisms are made up of one or more cells.

2. The cell is the basic unit of organization of all organisms.

3. All cells come from other cells already in existence.

Two Basic Cell Types1. Prokaryote

– Lacks internal compartments.

– No true nucleus.– Most are single-celled

(unicellular) organisms.– Examples: bacteria

Two Basic Cell Types2. Eukaryote

– Has several internal structures (organelles).

– True nucleus.– Either unicellular or

multicellular.•unicellular example:

yeast•multicellular examples:

plants and animals

Levels of Organization

https://www-brainpop-com.sled.idm.oclc.org/science/cellularlifeandgenetics/cells/

Did you know that you have 75 trillion cells that make up your body?! (that is thousands of times more than the number of people on the planet!)

5 Levels of Organization

Cells

Tissues

Organs

Organ Systems

Organism

Organism

• A living system that has several organ systems that function together.

• Examples: Animals, plants, and bacteria

Organ System

• A group of organs that carries out more generalized set of functions.

• Examples: digestive system and circulatory system.

Organ• Organs are two or

more types of tissues that work together to complete a specific task.

• Examples: heart or stomach.

Tissue• Groups of cells with

similar functions.

• Examples: Connective (bone, blood) and muscle tissue.

Cells

• The smallest unit of life. Cells preform specific functions.

• Example: muscle cell or skin cell

Levels of Organization Foldable Small

1. What is the definition of a tissue?

A tissue is a group of cells, found within an organism, that share similar functions.

2. What is the definition of an organ system?

An organ system is a group of organs that carries out more generalized set of functions.

3. What organism are you going to use in your foldable?
