Study Notes
Plant and Animal Tissues
- Meristematic Tissue: Responsible for increasing the length of stems and roots through cell division.
- Coconut Husk: Main constituent is coir, a fibrous material.
- Muscle Tissue: Responsible for movement in the body, enabling locomotion and various bodily functions.
- Phloem Composition: Consists primarily of sieve tube elements and companion cells.
- Neuron Structure: Dendrites are found at the receiving end of neurons, transmitting signals to the cell body.
Functions of Tissue Types
- Apical Meristem: Found at the tips of roots and stems, its primary function is to enable plant growth in length.
- Areolar Tissue: Functions as a loose connective tissue that provides support and elasticity, filling spaces between organs.
- Cardiac Muscles vs. Skeletal Muscles: Cardiac muscles are involuntary and striated, with intercalated discs, while skeletal muscles are voluntary and also striated but lack intercalated discs.
Plant Transport and Structure
- Xylem Function: Responsible for transporting water and inorganic salts from roots to aerial parts of plants, supporting photosynthesis and growth.
- Complex Plant Tissues: Characterized by their composite structure, consisting of multiple cell types working together for specific functions.
- Xylem Composition: Composed mainly of vessel elements and tracheids facilitating water transport.
Tissue Location and Characteristics
- Areolar Tissue Location: Found throughout the human body, particularly around organs and in subcutaneous tissue.
- Functions of Simple Tissues: Primarily provide mechanical support, storage, and photosynthesis in plants.
- Complex Tissues in Plants: Comprised of different cell types, such as sclerenchyma, collenchyma, and parenchyma, each serving distinct roles in plant function.
