Study Notes
Multicellular Organisms
- Multicellular organisms grow by generating more small cells rather than enlarging existing cells.
- Benefits of being multicellular include increased size, extended lifespan, and the ability for cells to specialize in specific functions.
Tissues
- A tissue is defined as a collection of cells that collaborate to perform a specific task.
- In animals, there are four primary types of tissues:
- Nerve tissue
- Muscle tissue
- Connective tissue
- Protective tissue
Plant Tissues
- Plants consist of three fundamental tissue types:
- Transport tissue
- Protective tissue
- Ground tissue
Organs and Organ Systems
- An organ is a structure composed of two or more types of tissues working collaboratively.
- An organ system consists of a group of organs that work together to carry out a particular function.
Plant Organs
- Key examples of plant organs include:
- Leaf systems
- Root systems
- Stem systems
Life Processes and Organization
- Any entity capable of performing life processes is designated as an organism.
- Unicellular organisms are those that consist of a single cell.
- Cells represent the lowest level of biological organization, while organ systems constitute the highest level.
Structure and Function
- The arrangement of parts within an organism is referred to as its structure.
- The specific role of a part within an organism is known as its function.
Respiratory System
- The tiny air sacs in the lungs, crucial for gas exchange, are known as alveoli.
