Study Notes
Tissues in Organisms
- All living organisms consist of cells; unicellular organisms perform all life functions with one cell, while multicellular organisms have specialized cells.
- In multicellular organisms, cells are grouped to efficiently carry out specific functions, resulting in a division of labor.
Differences Between Plant and Animal Tissues
- Plants are stationary and have more supportive tissue to maintain upright structure, predominantly composed of dead cells.
- Animals are mobile, consume more energy, and have primarily living tissues.
- Growth patterns differ; plants grow in specific regions (meristematic tissues), while animal growth is uniform throughout the body.
Types of Plant Tissues
- Vascular tissues, including phloem and xylem, are responsible for transporting food and water.
- Simple tissues include:
- Parenchyma: Contains chlorophyll in certain types, aids in photosynthesis, and may have air cavities for buoyancy in aquatic plants.
- Collenchyma: Provides flexibility and mechanical support, found in leaf stalks beneath the epidermis, with living, elongated cells.
- Sclerenchyma: Composed of dead cells, provides rigidity and strength to plant parts like coconut husks; cells have thickened, lignified walls.
Epidermal Tissue
- Forms a protective barrier for various organs and cavities, tightly packed with minimal intercellular space.
- Important for material exchange through permeability regulation; found in skin, blood vessels, and organs.
Types of Animal Tissues
- Connective Tissue: Includes areolar, adipose, bone, tendon, ligament, cartilage, and blood.
- Muscle Tissue:
- Striated muscle: Voluntary muscles with striped appearance; involved in body movements.
- Unstriated muscle: Involuntary, non-striated; found in organs.
- Cardiac muscle: Involuntary muscle specific to the heart, responsible for pumping blood.
Nervous Tissue
- Composed of neurons, which are specialized cells for receiving and transmitting impulses.
Examination Activities
- Use microscopy to compare plant tissue types, looking for differences in structure and function.
- Identify and differentiate various plant and animal tissues based on location and specific functions.
Key Functions of Stomata
- Allow gas exchange in plants, regulating water loss and CO2 intake for photosynthesis.
Summary of Epithelial Tissue Role
- Provides coverage and protection, forms barriers to maintain separate environments, and is integral in regulating material exchange.
Exercises
- Review definitions and differences between tissue types, and illustrate distinctions between muscle fibers.
- Identify specific tissues based on function and structure in practical contexts.
