This sequence describes the process where a cell grow, prepares for division, and divides to form two identical daughter cells

What is the cell cycle?

100

This baseline structural level of biological organization is followed sequentially by tissues, organs, organ systems, and the whole organism.

What is a Cell?

100

This basic, simple sugar molecule acts as the primary starting food source from which cells extract usable energy

What is Glucose?

100

This general term refers to any organism that is capable of creating its own food supply in the form of glucose.

What is an Autotroph? (or a Producer)

100

These three compounds represent the final outputs, or products, of a standard cellular respiration reaction.

What are carbon dioxide, water, and ATP (energy)?

200

These are the four primary biological functions or purposes of cell division in multicellular organisms.

What are growth, reproduction, replacement (of old cells), and repair (of damage)?

200

This body system consists of roughly 650 individual parts and controls all mechanical movements, including standing, smiling, and breathing.

What is the Muscular System?

200

This specific organelle is widely referred to as the "powerhouse of the cell" because it is the primary site where cellular respiration reactions occur.

What is the Mitochondrion? (plural: Mitochondria)

200

This green-colored chemical compound, located inside chloroplasts, absorbs the light energy required to fuel photosynthesis.

What is Chlorophyll?

200

Unlike animal cells which pinch inward, a plant cell must form this specialized, rigid structure across its middle to achieve cytokinesis.

What is a Cell Plate?

300

During this first major stage of the cell cycle, a cell grows to full size, produces necessary organelles, and creates an exact copy of its DNA.

What is Interphase?

300

Comprising the skin, hair, nails, and sweat glands, this system acts as a waterproof shield to safeguard the body against external injuries and infections.

What is the Integumentary System?

300

Represented by the abbreviation ATP, this molecule functions as the primary power currency that cells use to execute work

What is Adenosine Triphosphate?

300

This is the primary plant organ where Stage 1 of photosynthesis—capturing light energy—takes place

What is the leaf? (or leaves)

300

These three distinct types of muscle tissue comprise the muscular system to handle distinct voluntary and involuntary movements throughout the body.

What are skeletal, smooth, and cardiac muscles?

400

This specific term refers to the process where a cell makes a perfect copy of its DNA inside its nucleus before it splits.

What is Replication?

400

This control system relies on a complex network of glands—such as the thyroid and pancreas—to secrete chemicals that dictate mood, digestion, and temperature.

What is the Endocrine System?

400

This biochemical process allows organisms like yeast and bacteria to release energy from nutrients without utilizing any oxygen.

What is Fermentation?

400

These small, specialized pores on the underside of a plant's leaves allow carbon dioxide to enter the interior of the plant.

What are Stomata?

400

This type of fermentation takes place inside human muscle cells during intense exercise when oxygen cannot be replaced fast enough.

What is Lactic Acid Fermentation?

500

These threadlike structures, which contain two identical copies of DNA, are what chromatin condenses into during prophase.

What are Chromosomes?

500

This critical physiological process describes the passive mechanism by which oxygen and carbon dioxide cross into and out of the lungs.

What is Diffusion?

500

This first phase of respiration occurs strictly in the cytoplasm, requires zero oxygen, and breaks glucose down into pyruvate.

What is Glycolysis?

500

These two chemical compounds serve as the essential raw ingredients, or reactants, for the photosynthesis equation.

What are Carbon Dioxide (CO2) and Water (H2O)?

500

This type of consumer organism cannot generate its own food and must explicitly depend on the sun's energy indirectly by eating plants or plant-eating animals.

What is a Heterotroph?
