Animal Cells


Mitochondria

• Power house of the cells.
• Process of Respiration takes place here.

Respiration Equation

C6​H12​O6​+6O2​→6CO2​+6H2​O+ATP

GLUCOSE + OXYGEN → CARBON DIOXIDE + WATER + ENERGY

• Cells from your muscles has more mitochondria than those for example in your cheek.
• Where more energy is needed, there will be more mitochondria in the cells.

Cell Membrane

• Controls what enters and leaves the cell.
• Partially Permeable.
• Gives cell its Shape.

Cytoplasm

• Clear like jelly substance made up of 70% water with dissolved salts and minerals,
• All chemical reactions take place here.

Nucleus

• The brain of the cells
• Controls all activities of the cell.
• Contains genetic information for reproduction.

Ribosomes

• Important for synthesis of protein molecules.

Endoplasmic Reticulum

Rough Endoplasmic Reticulum (RER)

• Contains ribosomes attached to it.
• Packages and assembles proteins.

Smooth Endoplasmic Reticulum (SER)

• Have no ribosomes attached to it.
• Responsible for packaging fats and lipids.

Animal Cells have an irregular roundish shape

Plant Cells

ALL ANIMAL CELL ORGANELLES ARE FOUND IN A PLANT CELL.


Cell Wall

• Made up of Cellulose (tough material).
• Fully Permeable.

Chloroplast

• Has a green pigment called chlorophyl.
• Absorbs energy from sunlight to carry out a process called photosynthesis.

Large Permanent Vacuole

• Filled with cell sap.
• Animal Cells have vacuoles which are normally small and temporary.

Plant Cells have a Box Like Shape

Differences

Unicellular Organisms

• Organisms that only has 1 type of cell.
• Examples: Amoeba & Bacteria.

Multicellular Organisms

• Organisms that have more that 1 type of cell.
• Examples: Plants & Animals
