What is the primary pigment involved in photosynthesis?
Phycobilin
Chlorophyll
Xanthophyll
Carotene
Describe the overall equation for cellular respiration.
C6H12O6 + 3O2 -> 3CO2 + 3H2O + 2ATP
C6H12O6 + 6CO2 -> 6O2 + 6H2O + 36ATP
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
C6H12O6 + 6H2O -> 6CO2 + 6O2 + 18ATP
What are the two main types of nutrition in plants?
Photosynthesis and mineral absorption
Respiration and photosynthesis
Water absorption and carbon fixation
Nutrient storage and energy release
Explain the role of chlorophyll in photosynthesis.
Chlorophyll releases energy as heat during photosynthesis.
Chlorophyll absorbs light energy for photosynthesis, enabling the conversion of carbon dioxide and water into glucose and oxygen.
Chlorophyll converts sunlight into sound energy for plant communication.
Chlorophyll is responsible for the absorption of nutrients from the soil.
What is the function of the small intestine in the human digestive system?
The small intestine produces bile for fat digestion.
The small intestine stores waste before excretion.
The small intestine is primarily responsible for water absorption.
The small intestine absorbs nutrients and continues the digestion of food.
Name the organ responsible for detoxifying harmful substances in the body.
Heart
Liver
Lungs
Kidney
What is the process by which plants convert sunlight into chemical energy?
Transpiration
Photosynthesis
Fermentation
Respiration
Identify the main waste products excreted by humans.
Salts, proteins, and sugars.
Bile, hormones, and vitamins.
Carbon dioxide, water, and glucose.
Urea, creatinine, and undigested food.
How do plants obtain nitrogen for their growth?
Plants synthesize nitrogen from carbon dioxide.
Plants rely solely on animal waste for nitrogen.
Plants absorb nitrogen directly from the air.
Plants obtain nitrogen through nitrogen fixation and absorption of nitrates from the soil.
What is the significance of the large intestine in digestion?
The large intestine produces most of the digestive enzymes.
The large intestine is significant for water absorption, waste compaction, and housing beneficial bacteria.
The large intestine is primarily responsible for protein digestion.
The large intestine is where most nutrient absorption occurs.
