Study Notes
Objectives of the Lesson
- Identify various cell types in plant and animal tissues.
- Classify these cells and describe their functions.
- Understand how cells, tissues, organs, and organ systems work together to sustain life.
Levels of Organization
- An organ consists of multiple tissues working collaboratively for a specific function.
- An organ system comprises different organs that perform related functions.
- Tissues are made up of similar cells that work together.
- Cells are the fundamental units of life, forming all living organisms.
Plant Tissues
- Types of Tissues:
- Collenchyma, parenchyma, sclerenchyma (support and storage).
- Meristematic tissues (apical, ground, procambium) for growth.
- Apical Meristems:
- Regions capable of cell division and growth at root and shoot tips.
- Contribute to the primary plant body and root/shoot extensions.
- Non-Meristematic Tissues:
- Parenchyma is involved in photosynthesis, respiration, and protein synthesis.
Transportation Tissues in Plants
- Xylem:
- Transports water and dissolved minerals from roots to stems and leaves.
- Phloem:
- Distributes food made in leaves to all plant parts.
Types of Tissues in Multicellular Animals
- Major Types:
- Connective, epithelial, muscular, and nervous tissues.
- Epithelial Tissues:
- Cover external and internal surfaces, including the digestive and respiratory tracts.
- Nervous Tissues:
- Responsible for receiving and transmitting impulses throughout the body.
Muscle Tissues
- Cardiac Muscle:
- Involuntary muscle found exclusively in the heart.
- Types of Muscle Tissue:
- Includes cardiac, skeletal, and smooth (visceral) muscles.
Importance of Connective Tissues
- Connective tissues bind and support different body parts.
- They serve as a packing material and help in excretion and secretion.
- Provide structural support and strength to bodily structures.
Nervous Tissues Functions
- Motor neurons transmit signals away from the central nervous system to effectors.
