The kingdom that humans belong to

What is Animalia? 

100

This organelle is known as the control center of the cell. 

What is the nucleus? 

100

This is the correct order of cellular organization from smallest to largest:

What is cell, tissue, organ, organ system, organism? 

100

This system is responsible for bringing oxygen into the body

What is the respiratory system? 

100

A cell would need this organelle to survive because it provides energy.

What is the mitochondria? 

200

The main difference between plants and fungi is this ability plants have but fungi do not.  

What is making their own food?

200

This organelle is responsible for producing energy. 

What is the mitochondria? 

200

Groups of similar cells working together form this

What is a tissue? 

200

This system transports nutrients and oxygen throughout the body.

What is the circulatory system? 

200

If an organism can make its own food, it may belong to this kingdom.

What is the plant kingdom? 

300

This is the main reason scientists classify organisms into groups.

What is to make it easier to study and compare living things?

300

This organelle removes waste and breaks down worn-out cell parts. 

What is the lysosome? 

300

The heart belongs to this level of organization. 

What is an organ? 

300

These two systems work together to allow the body to move.

What are the muscular and nervous systems? 

300

These two systems are affected first when oxygen levels in the body drop.

What are the respiratory and circulatory systems? 

400

These are the two kingdoms that contain prokaryotes. 

What are Archaea and Bacteria?

400

This organelle is essential for survival because it controls what enters and exits the cell. 

What is the cell membrane? 

400

This is the main difference between organs and organ systems

What is organs have one main job while organ systems are groups of organs working together?

400

This explains how the digestive and circulatory systems depend on each other.

What is one breaks down nutrients and the other transports them? 

400

This describes the alleles in an organism that has two of the same letters for a trait

What is homozygous? 

500

A scientist finds an organism in the forest. Instead of describing how it looks, she studies its cell type and how it works to decide which kingdom it belongs to. This shows why classification depends on these characteristics.

What are cell structure and function?

500

This would happen to a plant cell if it lost its chloroplasts. 

What is it could not make food and would eventually die? 

500

After eating lunch, different parts of the body work together to break down the food and use the nutrients. This teamwork represents this level of organization.

What is an organ system? 

500

After running laps, a student is breathing fast and their heart is beating quickly. These two systems are working together to help their body recover.

What are the respiratory and circulatory systems? 

500

This term describes an organism with two different alleles for a trait

What is heterozygous?
