Life Processes

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.
