Organisms composed of many specialized cells working together.

Cells designed to perform specific functions within an organism.

Cells that capture prey using stinging mechanisms.

Single-celled organisms can survive and function on their own.

Specialized animal cells cannot survive independently.

A ranking system in biology from least to most complex.

Different animals show varying levels of body complexity.

The structured layers in animal bodies, from cells to systems.

The smallest unit of organization, consisting of individual cells.

Groups of similar cells working together to perform a specific function.

Structures composed of two or more tissue types that work together for specific functions.

Groups of organs that work together to perform complex functions for the body.

The complete living entity that can function independently; all organ systems work together.

An organ system that transports nutrients, gases, and wastes through the body.

An organ that pumps blood throughout the circulatory system.

Functions including nutrient acquisition, waste elimination, and reproduction that all organ systems perform.

A thin sheet of tightly packed cells that covers body surfaces and lines internal organs and cavities.

A specialized tissue that provides support and protection for various parts of the body.

A group of specialized tissues containing proteins that can contract and enable the body to move.

Specialized tissue that conducts electrical signals from one part of the body to another.

The four major types of tissue in animals are epithelial, connective, muscle, and nerve tissue.

Supports the body and enables movement.

Takes in oxygen and removes carbon dioxide.

Sends messages around the body.

Breaks down food for nutrient absorption.

Produces eggs and sperm for reproduction.

Excretes waste and regulates water balance.

Specialized structures that perform functions.

Epithelial, connective, muscle, and nerve are the four main tissue types in animals.

Organ systems are composed of multiple organs that work together, making them more complex than specialized cells.

All living things must perform basic functions like nutrient acquisition, waste elimination, and reproduction.

There is no hierarchy of organization in single-celled organisms as they function independently.

Protection from dehydration and creates low-friction surfaces.

Provides support, insulation, and binds other tissues.

Facilitates movement by contracting muscles.

Involved in sensory perception and coordination of body functions.

Four primary types: epithelial, connective, muscle, and nerve.

Organization of body structures from cells to systems.
