Study Notes
Main Differences Between Plant and Animal Tissue
- All multicellular organisms, including plants and animals, consist of groups of specialized cells called tissues.
- Plant tissues consist of both living and non-living cells, leading to lower energy demands compared to animal tissues, which are made solely of living cells.
- Primary function of plant tissue is structural support; for animal tissue, it facilitates locomotion.
Plant Tissue Overview
- Definition: Specialized group of cells performing specific functions in plants.
- Cell Structure: Contains a cellulose cell wall, vacuoles, and photosynthetic pigments like chlorophyll.
- Types: Divided into meristematic and permanent tissues.
Meristematic Tissue
- Characteristics: Capable of continuous division throughout a plant's life.
-
Types:
- Apical Meristem: Located at shoot and root tips, responsible for primary growth.
- Intercalary Meristem: Involved in increasing girth in monocots.
- Lateral Meristem: Gives rise to vascular cambium.
Permanent Tissue
- Definition: Composed of cells that do not divide further.
-
Categories:
- Simple Permanent Tissue: Made of similar cell types—includes parenchyma (thin-walled, living), collenchyma (thick-walled, living), and sclerenchyma (thick, secondary walls).
- Complex Permanent Tissue: Composed of multiple cell types—includes xylem (conducts water and minerals) and phloem (conducts organic substances).
Plant Tissue Systems
- Dermal Tissue: Forms protective outer layer, includes epidermis (prevents water loss and facilitates gas exchange) and periderm (stem bark).
- Ground Tissue: Supports photosynthesis and stores food; includes parenchyma, collenchyma, and sclerenchyma.
- Vascular Tissue: Consists of xylem and phloem; essential for transport of water, minerals, and nutrients throughout the plant.
Animal Tissue Overview
- Definition: Specialized groups of similar cells that perform specific functions in animals.
- Cell Structure: Lacks cell walls and vacuoles, differing from plant cells.
Key Terms
- Animal tissue includes: Connective Tissue, Epithelial Tissue, Muscle Tissue, Nerve Tissue.
- Plant tissue includes: Meristematic Tissue, Permanent Tissue, Epidermal Tissue, Ground Tissue, Vascular Tissue.
