Study Notes
Plant Cell Structures and Functions
- Plants are essential for maintaining Earth’s ecosystems and provide numerous benefits.
Learning Objectives
- Distinguish between meristematic and permanent tissues in plants.
- Identify functions of different plant tissues and their locations in plant parts.
Plant Tissues
-
Meristematic Tissues: Found in growing areas, capable of cell division.
- Apical Meristems: Located at root tips and shoots, responsible for primary growth (length increase).
- Lateral Meristems: Responsible for secondary growth (diameter increase) and includes vascular cambium and cork cambium.
- Vascular Cambium: Produces secondary xylem (wood) and phloem.
- Cork Cambium: Replaces epidermis with cork cells in mature plants, contributes to bark.
-
Permanent Tissues: Comprised of non-dividing cells.
-
Simple Permanent Tissues: One cell type.
- Epidermal Tissue: Covers plant surfaces; protects against water loss and pathogens.
-
Ground Tissue: Includes parenchyma, collenchyma, and sclerenchyma.
- Parenchyma: Functions in storage and photosynthesis.
- Collenchyma: Provides flexible support to young plant parts.
- Sclerenchyma: Provides rigid support, consists of sclereids (seed coats) and fibers (commercial use).
-
Complex Permanent Tissues: More than one cell type.
-
Xylem: Transports water and minerals; composed of tracheids and vessel elements.
- Tracheids: Long, thin cells facilitating water flow.
- Vessel Elements: Have perforated plates for efficient water transport.
- Phloem: Transports nutrients (sucrose) throughout the plant via sieve-tube elements.
-
Xylem: Transports water and minerals; composed of tracheids and vessel elements.
-
Simple Permanent Tissues: One cell type.
Plant Growth
- Primary Growth: Increases the height of plants (driven by apical meristems).
- Secondary Growth: Increases the girth of plants (driven by lateral meristems).
Ground Tissues
- Often referred to as fundamental tissues due to their critical roles in plant growth, development, and overall function.
Summary of Functions
- Meristematic tissues initiate the formation of permanent tissues responsible for various functions, including photosynthesis, structural support, and nutrient transport.
