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.
