Plant and Animal Cells 2

Lesson 2

September 23rd, 2010

Plant and Animal cell diagrams

  • We will refer back to these diagrams all lesson

  • Every time we go back to the diagram add the organelle name to your diagram

From Yesterday -Add these to your diagrams


Cell Membrane


  • Chromatin

Cell Membrane


Vacuoles and Vesicles

  • Membrane-bound organelles that store nutrients, wastes, and other substances used by the cell

  • In plant cells, the central vacuole stores water for the cell. When water the cell, the central vacuole swells, causing the plant cell to become firm.

  • Vesicles transport substances throughout the cell.

Vacuoles and Vesicles

Central Vacuole




  • Powerhouses of the cell.

  • Reactions occur in these organelles to convert the chemical energy in sugar into energy that the cell can use. (Part of cellular respiration)



  • Where digestion takes place.

  • Small and round

  • Filled with enzymes (natural catalysts)

    • A protein that can speed up chemical reaction in the cell.

  • Break down invading bacteria and damaged cell organelles


Golgi Apparatus

  • Receives proteins from the endoplasmic reticulum.

  • modifies, sorts, and packages proteins for delivery throughout the cell or outside of the cell.

  • Looks like a stack of flattened membranes

Golgi Apparatus

Golgi Apparatus

Endoplasmic Reticulum (ER)

  • Made of a series of interconnected small tubes that carry materials through the cell.

Endoplasmic Reticulum (ER)

  • Rough endoplasmic reticulum is associated with making proteins

    • ER that contains ribosomes

  • Ribosomes are small, dense-looking organelles that may be attached to the rough endoplasmic reticulum or free in the cytoplasm.

    • Sites where proteins are assembled.

Endoplasmic Reticulum (ER)

  • Smooth endoplasmic reticulum

    • Associated with the production of fats and oils

    • Does not have ribosome's

Rough endoplasmic reticulum

Smooth endoplasmic reticulum


(small dots)


  • Internal network of fibres of protein filaments.

  • Maintains the cell’s shape.


Organelles in Plant Cells

  • Some organelles are found only in plant cells.

    Cell Wall

  • Only plant cells, bacteria, fungi, and some algae have a cell wall.

  • The Rigid frame around the cell that provides strength, protection, and support

Cell Wall


  • Only in plant cells and some algae.

  • Contain a green substance called chlorophyll.

    • Uses energy from the Sun to convert carbon dioxide and water into sugar and oxygen in a process called photosynthesis.



  • Made up of little sacs known as thylakoids.

    • Resemble a stack of coins.

    • Surrounded by a thick fluid called stroma.

  • A stack of thylakoids is called a granum

Differences between Plant and Animal Cells - Plants

  • Contain Chlorophyll – photosynthesis

  • Large central Vacuole

  • Store energy in the forms such as cornstarch and oil

Differences between Plant and Animal Cells - Animals

  • Small Vacuole

  • Store energy in form of glycogen, carbohydrates, and lipids (fat)

  • Some have specialized compounds for haemoglobin and cholesterol

Differences between Plant and Animal Cells - Animals

  • Centrioles – Paired structures used in cell division.

  • Cilia or flagellum –used for movement


  • Finish Lab and hand in

  • Finish and hand in questions 1-5
