Study Notes
Cells and Tissues Overview
- Prokaryotic cells lack a nucleus; eukaryotic cells possess one.
- Mitochondria serve as the energy-producing organelles in both plant and animal cells.
- Ribosomes are essential for protein production within cells.
- Fimbriae are bristle-like appendages that allow prokaryotes to adhere to surfaces.
- Plasmids are structures commonly found in bacteria and can carry genetic information.
Learning Competencies and Objectives
- Classify different cell types in plant and animal tissues.
- Differentiate between parenchyma, sclerenchyma, and collenchyma cells in plants.
- Describe the functions of dermal, ground, and vascular tissues in plants.
- Identify various animal cell types, including blood, nerve, and bone cells.
- Explain the functions of the four major animal tissue types.
Plant Tissues and Histology
- Histology is the study of cells and tissues.
- Plant tissue is divided into meristematic and permanent types.
- Meristematic tissue comprises young, immature cells that continuously divide, contributing to plant growth in length and girth.
- Permanent tissue arises from meristems and comprises mature, non-dividing cells.
Types of Plant Meristems
- Primordial Meristem: Earliest tissue, arises from embryonic origin.
- Primary Meristem: Develops into three types:
- Protoderm: Forms the epidermis.
- Procambium: Develops into primary xylem and phloem.
- Ground Meristem: Forms cortex and pith.
- Secondary Meristem: Lateral meristems that include:
- Vascular cambium: Produces secondary xylem and phloem.
- Cork cambium: Produces periderm, replacing the epidermis.
Types of Permanent Plant Tissues
- Dermal Tissue: Protective outer covering of plants, includes:
- Epidermis: A single layer of parenchymatous cells containing stomata and cuticle.
- Periderm: Multilayered, replaces epidermis during secondary growth.
- Ground Tissue: Fills soft parts of plants, involved in photosynthesis and storage.
- Vascular Tissue: Transport system for water and nutrients throughout the plant.
Types of Ground Tissue
- Parenchyma: Thin-walled living cells, involved in photosynthesis and storage.
- Collenchyma: Elongated cells with thicker walls, provide flexible support.
- Sclerenchyma: Dead cells with thick, rigid walls, provide mechanical support.
Vascular Tissue Components
- Xylem: Composed of non-living cells; transports water and minerals from roots to leaves.
- Phloem: Complex tissue responsible for nutrient transport throughout the plant.
Functions of Meristematic Tissue
- Differentiate into specialized structures, responsible for growth and development.
- Help in tissue formation, leading to plant structure maturity.
Summary of Major Plant Tissue Functions
- Dermal tissue: Provides a protective layer for plants.
- Ground tissue: Fulfills storage, photosynthesis, and support needs.
- Vascular tissue: Transports water and nutrients across plant systems.
Key Terms
- Meristematic Tissue: Undifferentiated cells for growth.
- Permanent Tissue: Mature cells that have established specific functions.
- Xylem and Phloem: Primary transport tissues in vascular plants.
