This cellular structure controls the movement of matter into and out of the cell

Cell Membrane

This basic unit represents the least complex level of biological organization.

cell

This body system works closely with the muscular system to send signals to enable movement.

Nervous

This is the critical first biological step in information processing in an organism.

Sensory receptor detects stimulus

Known as the "powerhouse", this organelle converts stored energy into a usable form for the cell.

Mitochondria
200

This level of organization is defined as a group of similar cells working together to perform a specific function.

tissue

200

This critical body system is primarily responsible for bringing essential oxygen into the body through lungs.

Respiratory

300

This structure captures energy from sunlight and converts it into stored chemical energy.

Chloroplast

300

Directly preceding an organ system in complexity, this is a group of different tissues working together (e.g., the stomach).

organ
300

This system coordinates with the respiratory and digestive systems to deliver oxygen and nutrients throughout the body.

Circulatory

300

An advantageous genetic trait (like a stronger jaw for eating coral) makes organisms more likely to do these two things over time.

400

This structure provides support for the cell.

Cell Wall

A group of similar tissues working together

organ

This system is mainly responsible for carrying sensory signals to the brain and controlling quick responses.

Shared embryonic characteristics—like gill slits and tails found in frog, turtle, rabbit, and pig embryos—suggest this about the evolutionary history of vertebrates.
