What is the primary function of the digestive system?

What is breaking down food to absorb nutrients?

100

This is the main molecule produced during cellular respiration that cells use for energy.

What is ATP?

100

These are the primary photosynthetic pigments in plants that absorb light energy.

What are chlorophylls?

100

This organ filters waste from the blood and produces urine.

What is the kidney?

100

This rigid outer layer is found in plant cells but not in animal cells, providing structural support.

What is the cell wall?

200

Which digestive organ releases acid to help break down food?

What is the stomach?

200

This is the first stage of cellular respiration and takes place in the cytoplasm.

What is glycolysis?

200

This is the gas taken in by plants from the atmosphere through small pores on their leaves, essential for photosynthesis.

What is carbon dioxide?

200

This tube carries urine from the kidneys to the bladder.

What is the ureter?

200

Name one organelle that is present in both animal and plant cells and is responsible for generating energy for the cell.

What is the mitochondrion (or mitochondria)?

300

In what order does food pass through the first three main parts of the digestive tract?

What are the mouth, esophagus, and stomach?

300

This gas must be present for the Krebs cycle and electron transport chain to proceed.

What is oxygen?

300

These are the organelles within plant cells where photosynthesis takes place.

What are chloroplasts?

300

This muscular sac stores urine before it is expelled from the body.

What is the urinary bladder?

300

These are the basic structural and functional units of all living organisms, including both animals and plants.

What are cells?

400

In which part of the digestive system does most nutrient absorption occur?

What is the small intestine?

400

When oxygen is not available, human muscle cells perform this type of respiration, producing lactic acid.

What is anaerobic respiration (or lactic acid fermentation)?

400

This is the source of energy that drives the process of photosynthesis.

What is sunlight (or light)?

400

This is the tube through which urine is expelled from the urinary bladder out of the body.

What is the urethra?

400

Name one organelle involved in protein synthesis that is found in both animal and plant cells.

What are ribosomes?

500

Why doesn’t the stomach digest itself even though it contains strong acid and enzymes?

What is because the stomach is protected by a thick layer of mucus?

500

These two waste products are released during aerobic cellular respiration.

What are carbon dioxide and water?

500

Plants release this gas as a byproduct of photosynthesis, which is essential for animal life.

What is oxygen?

500

This is the general term for the fluid that is filtered from the blood in the kidneys and eventually becomes urine.

What is filtrate (or glomerular filtrate)?

500

Describe a key difference in how animal and plant cells obtain energy.

What is that animal cells obtain energy by consuming organic molecules, while plant cells can produce their own energy through photosynthesis in chloroplasts?
