It controls the cells functions
What is protoplasm?

What are the common characteristics of all body cells?
Ability to absorb nutrients, which are used for growth and repair
Ability to utilize oxygen and nutrients in order to release heat and energy, which as a result product CO2 and H2O
Ability to increase size and multiply
Ability to respond to environmental change
What is cytoplasm?
Substance which contains the nutrients necessary for growth, reproduction and repairation
What is the mitochondria?
Provides the energy the cell needs
What is cellular respiration?
Glucose + oxygen ➡️ carbon dioxide + water + energy
What types of tissue are there?

Examples of parts of the body that are made up of epithelial tissue:
Skin
Lining of the heart
Blood and lymphatic vessels
Respiratory organs
What does stratified mean?
Many layers
What do we call a tissue with a single layer of cells?
Simple tissue
What do we call a tissue with several layers of cells?
Compound tissue
What type of simple epithelial tissue is this?
Squamous epithelium
