Study Notes
Types of Meristematic Cells
- Apical Meristems: Located at root and stem tips; promote vertical growth and lengthening of plants.
- Lateral Meristems: Found in the radial areas of stems and roots; responsible for increasing plant thickness.
- Intercalary Meristems: Located at the bases of leaves; contribute to the variation in leaf size.
Functions of Meristematic Cells
- Critical for overall plant growth in height and width.
- Responsible for leaf size variation.
- Differentiate into permanent tissues, aiding in plant development.
Types of Plant Cells
-
Epidermal Cells: Protective external layer against water loss and pathogens; densely packed with a waxy cuticle.
- Pavement Cells: Help regulate internal temperature of the plant.
- Stomatal Guard Cells: Control water availability and gas exchange through stomata.
- Trichomes: Hair-like structures that deter herbivores and provide protection from pathogens.
Plant Tissues
- Dermal Tissue: Outer protective layer made up of epidermal cells, preventing water loss.
- Ground Tissue: Comprises parenchyma, collenchyma, and sclerenchyma cells; involved in photosynthesis, storage, and structural support.
Types of Parenchyma Cells
- Palisade Parenchyma: Columnar cells in leaves, crucial for light absorption and gas exchange.
- Ray Parenchyma: Found in wood; assists in material transport and horizontal arrangement for support.
Types of Sclerenchyma Cells
- Fiber Sclerenchyma Cells: Provide structural support due to thickened cell walls; essential for tree trunks and protection against herbivores.
- Sclereid Sclerenchyma Cells: Protect other plant tissues; consumed by herbivores may harm digestive systems.
Xylem and Phloem Cells
- Xylem Cells: Complex cells that transport water and nutrients from roots to other plant parts; remain alive at maturity.
- Phloem Cells: Carry food from leaves to other parts of the plant; rely on osmotic pressure for transport.
Meristematic Cells
- Continually divide throughout a plant's life.
- Possess self-renewal capabilities and high metabolic activity.
Cell Modification
- Specialization occurs after division, where new cells undergo structural adaptations for specific functions.
