Page 2: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

It all begins with CORK in 1665.

Page 3: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures which he called “animalcules.”

History of CellsHistory of Cells

Page 4: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Today, we know that they were not animals, but single-celled organisms.

Three scientists, Schleiden, Schwann, and Virchow put together what we know today as the cell theory.

Page 6: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

1. All living things are made of one or more cells.

2. Cells are the basic unit of structure and function in living things.

3. All cells arise from existing cells.

PROKARYOTES◦The smallest and simplest cells are prokaryotes.

◦They are single-celled organisms that lack a nucleus and other internal compartments.

EUKARYOTES◦The first cells with internal compartments.

◦Evolved about 2.5 billion years ago. ◦Eukaryotes include plants and animals and have a nucleus and other membrane bound organelles.

Page 11: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures
Page 12: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Without separate compartments (organelles), prokaryotes cannot carry out many specialized functions.

Page 13: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

They are very simple and very small. “Pro” rhymes with “NO”…they have NO nucleus.

Page 14: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

The familiar prokaryotes that cause infection and food to spoil belong to a class commonly called bacteria.

They also have vitally important roles in earth’s ecosystems.

Page 15: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

They can live in a range of environments: some do not even need oxygen to survive, some make their own food, some live in extreme hot or extreme cold.

Page 16: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

They can grow and divide very rapidly.

Page 17: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

There are no internal organelles, so the cell’s enzymes and ribosomes are free to move around in the cytoplasm.

Page 18: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures
Page 19: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Genetic material (DNA or RNA) is a single circular molecule. This loop is located near the center of the cell.

Page 20: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Cell Membrane (Cytoplasmic Membrane) that allows certain materials in/out of the cell.

Page 21: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

There is a cell wall that surrounds the cell membrane, providing structure and support.

Page 22: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

They lack the internal supporting skeleton, so they depend on a strong cell wall to give the cell shape.

Page 23: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Some have flagella, long threadlike structures that protrude from the cell’s surface and enable movement.

Page 24: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Some may have cilia for movement.

Page 25: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Ribosomes to make proteins.

Page 26: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Prokaryotes are BACTERIA. Prokaryotes have NO nucleus. PRO rhymes

with NO….NO NUCLEUS! Prokaryotes have CELL WALLS.

Page 27: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

EUKARYOTE – an organism whose cells have a nucleus and membrane bound organelles.

COMPARTMENTALIZATION COMPARTMENTALIZATION COMPARTMENTALIZATION

Compartmentalization allows for specialization.

Page 28: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Eukaryotes include Plants and Animals.

Page 29: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

EU rhymes with Do….Eukaryotes DO HAVE A NUCLEUS!

Page 30: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Cell wall – only in plants. Composed of proteins and carbohydrates, including cellulose, it helps support and maintain the shape of the cell, protects it from damage, and connects it with adjacent cells.

Page 31: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Chloroplast – only in plants. Organelles that use light energy to make carbohydrates from CO2 and H2O.

Page 32: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Central Vacuole – only in plants. Stores water. When the central vacuole is full, it makes the cell rigid, which enables the plant to stand upright.

Page 33: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Cytoplasm – includes everything inside the cell membrane, but outside the nucleus.

Page 34: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Flagella and Cilia – only in some animal cells. Both are used for movement. Flagella is like a long tail. Cilia are short, hair like structures.

Page 35: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Cytoskeleton – provides the internal support for animal cells, much like a human skeleton.

Page 36: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Cell Membrane – a fluid barrier separating the inside from the outside of the cell. This barrier allows only certain substances into the cell and out of the cell.

Page 37: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Nucleus – contains DNA. It is like the brain of the cell and regulates the cells functions.

Page 38: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Nucleolus – small dense region in the center of the nucleus that puts together ribosomes.

Page 39: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Ribosomes – make proteins.

Page 40: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Endoplasmic Reticulum – the highways system of the cell that transports proteins. If it has ribosomes stuck to it, its known as rough E.R. If it does not have ribosomes stuck to it, it is known as smooth E.R.

Page 41: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Golgi Apparatus – packaging and distribution center of the cell.

Page 42: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Lysosomes – digestion center of the cell.

Page 43: It all begins with CORK in 1665. 10 years later, Anton van Leeuwenhoek viewed pond water under a microscope and discovered many tiny, living creatures

Mitochondria – The powerhouse of the cell. By breaking down big molecules, the mitochondria makes ATP for the cell. ATP is energy!
