Study Notes
Phloem
- Composed of sieve tubes, companion cells, phloem parenchyma, and phloem fibres.
- Transports food in both directions.
- Phloem fibres are the only dead cells in phloem.
Xylem
- Made up of vessels, tracheids, xylem parenchyma, and xylem fibres.
- Vessels and tracheids conduct water and minerals from the soil.
- Xylem parenchyma stores food.
- Xylem fibres provide mechanical support.
Epithelial Tissues
- Found on the outer layer of a body or organ surface.
- Form the outermost protective layer of most animals.
Squamous Epithelium
- Extremely thin and flat layer of cells.
- Semi-permeable, ideal for gaseous exchange.
- Found in the lining of the esophagus and mouth.
Cuboidal Epithelium
- Cuboidal in shape.
- Lines salivary glands and kidney tubules.
- Provides mechanical support.
- Forms glandular epithelium when they form glands.
Columnar Epithelium
- Lines organs involved in absorption and secretion, such as the intestines.
- Made up of elongated cells.
- Forms ciliated columnar epithelium when cilia are present, found in the respiratory tract.
Stratified Squamous Epithelium
- Multiple layers of squamous epithelium arranged in a pattern.
- Forms our skin.
Muscular Tissue
- Makes up muscles responsible for body movements.
Striated/Skeletal Muscles
- Responsible for voluntary movements.
- Attached to bones.
- Long, cylindrical, unbranched, striated, and multinucleated.
Unstriated/Smooth Muscles
- Responsible for involuntary movements.
- Found in places like the alimentary canal and blood vessels.
- Long, smooth, spindle-shaped, and uninucleated.
Cardiac Muscles
- Make up the heart.
- Involuntary, with rhythmic contractions and relaxations.
- Branched, uninucleated, contains intercalated discs.
Connective Tissues
- Connect different parts of the body.
- Examples include blood, bones, cartilages, tendons, ligaments, areolar tissues, and adipose tissues.
Nervous Tissue
- Makes up the brain, spinal cord, and nerves.
- Responsible for sensations, consciousness, memory, and emotion.
Neurons
- Cells that form the nervous system.
- Composed of a cell body, axon, and axon terminals.
