Study Notes
Tissues
- Tissues are groups of similar cells that work together to perform a specific function.
- Plants and animals both have a variety of tissues.
Plant Tissues
-
Meristematic Tissue: Actively dividing cells with thin cell walls, dense cytoplasm and no vacuoles. Responsible for growth in plants.
- Apical Meristem: Found at the tips of roots and stems, responsible for increase in length.
- Lateral Meristem: Found in the cambium layer and responsible for increase in girth.
- Intercalary Meristem: Found at the base of leaves and internodes, responsible for increasing the length of internodes.
-
Permanent Tissue: Cells that have stopped dividing and are specialized for a specific function.
- Parenchyma: Thin-walled cells with large vacuoles. Involved in storage, photosynthesis, and gas exchange.
- Collenchyma: Thick-walled cells with uneven thickening at corners. Provide flexibility and support.
- Sclerenchyma: Thick-walled cells with lignin. Provide strength and support.
Animal Tissues
- Epithelial Tissue: Forms coverings and linings of organs and cavities. Function is protection, absorption, secretion, and excretion.
-
Connective Tissue: Provides support, connects different tissues, and aids in transport.
- Areolar Tissue: Loose connective tissue with collagen and elastin fibers. Found beneath the skin and around organs.
- Adipose Tissue: Fat-storing tissue, acts as insulation and energy reserve.
- Skeletal Tissue: Includes cartilage and bone. Offers support, protection, and movement.
- Blood: Fluid connective tissue that transports oxygen, nutrients, and waste products.
-
Muscle Tissue: Specialized for contraction and movement.
- Striated Muscle: Attached to bones and responsible for voluntary movement.
- Smooth Muscle: Found in the walls of internal organs and responsible for involuntary movement.
- Cardiac Muscle: Found in the heart and responsible for the heart's beating.
-
Nervous Tissue: Composed of neurons and glial cells. Responsible for communication and coordination in the body.
- Neurons: Conduct nerve impulses. Have dendrites and an axon.
Key Points
- The girth of the stem increases due to Lateral Meristem.
- The length of the stem increases due to Apical Meristem.
- Plants have more living tissues compared to animals.
- The human body stores fat in Adipose Tissue.
- Cartilage is found in the nose, ear, and trachea.
- Involuntary muscles are smooth and cardiac muscle.
- Xylem Parenchyma helps in sideways conduction of water.
