Cell

• Meiosis produces four non-identical daughter cells from a single parent cell.
• Epithelial tissue is a covering or protective tissue.
• Epithelial tissue is the simplest tissue.
• Epithelial tissue covers the animal body externally and internally.
• The cells in epithelial tissue are tightly packed with no intercellular space.
• The cells in epithelial tissue form a continuous sheet.
• A small amount of cementing material is present between the cells in epithelial tissue.
• Permeability plays an important role in epithelial tissue, both internally and externally.
• Epithelial tissue has an extracellular fibrous basement membrane underneath it.
• Epithelial tissue is present at the skin, lining of mouth, lining of blood vessels, lung alveoli, and kidney tubules.
• Epithelial tissue comes in four types: simple squamous, stratified squamous, simple cuboidal, and simple columnar.
• Simple squamous epithelium is present at the lining of blood vessels, lung alveoli, and oesophagus, and forms a delicate lining.
• Stratified squamous epithelium is found in the skin.
