Cell Theory and Levels of Organization
100

This body system is responsible for transporting blood, gases, and nutrients throughout the body

What is the circulatory system

100

This organelle is found in all eukaryotic cells and is the control center for the cell.

What is the nucleus.

100

This 3 lettered acid is the genetic material held inside the nucleus passed down from parent to offspring

What is DNA

100

According to cell theory, this is the smallest unit of life.

What is a cell

200
This body system acts as a barrier between the body and the outside world.

What is the integumentary system

200

Organelle present in both plant and animal cells, responsible for energy production

What is the mitochondria

200

An organism that reproduces quickly in a stable environment and produces uniform offspring is most likely using this type of reproduction.

What is asexual reproduction

200

All cells come from these type of cells

What are pre-existing cells

300

These TWO body systems work together to help the body move.

What are the muscular and skeletal systems

300

These two organelles are found only in plant cells

What are cell wall and chloroplasts

300

Because offspring are genetically different from one another, this type of reproduction is more common in changing environments.

What is sexual reproduction

300

All living things are made of these

What are cells

400

These TWO body systems work together to transport and absorb nutrients.

What are the digestive and circulatory system

400

These organelles are responsible for protein synthesis and are found in both plant and animal cells.

What are ribosomes. 

400

Budding, binary fission, fragmentation, and parthenogenesis are examples of this type of reproduction.

What is asexual reproduction 

400

A group of similar muscle cells working together to contract is an example of this level of organization.

What is tissue

500

These TWO body systems work together to regulate water balance in the body.

What are the nervous and urinary/excretory system.

500

This organelle contains the genetic material that makes you, you!

What is the nucleus 

500

This is one disadvantage of asexual reproduction: a disease could wipe out an entire population.

What is lack of genetic variation

500

This is the correct order from smallest to largest: cell → tissue → organ → ___ → organism.

What is organ system
