Nutrition in plants

Name the gas needed by plants for photosynthesis

• Hydrogen
• Nitrogen
• Carbon dioxide (CO2)
• Oxygen

Name the green pigment found in plants important for photosynthesis

• Xanthophyll
• Carotenoid
• Melanin
• Chlorophyll

Name the organelle into which photosynthesis occurs in plants

• Mitochondria
• Chloroplasts
• Nucleus
• Ribosomes

State the importance of nitrate to plants

• Plants do not require nitrate for growth and development
• Nitrate is important to plants because it is a major component of amino acids, proteins, and chlorophyll, essential for photosynthesis, growth, and development.
• Nitrate is only used by plants for energy production
• Nitrate has a negative impact on plant photosynthesis

Name the gas produced during photosynthesis

• Hydrogen gas (H2)
• Oxygen gas (O2)
• Nitrogen gas (N2)
• Carbon dioxide (CO2)

State the importance of magnesium to plants

• Magnesium has a negative impact on plant health
• Magnesium is important to plants for photosynthesis, enzyme activation, and nutrient uptake.
• Magnesium is only needed for plant growth
• Plants do not require magnesium for any biological processes

What best describe a limiting factor of photosynthesis?

• Humidity level
• Soil pH level
• Environmental conditions such as light intensity, carbon dioxide concentration, and temperature
• Wind speed

Name the structure which transport water in plants

• phloem
• xylem
• stem
• chlorophyll

Name the structure which transport sucrose in plants

• Chloroplasts
• Stomata
• Phloem
• Xylem

Through which structure carbon dioxide enters a leaf for photosynthesis

• Chloroplasts
• Xylem
• Guard cells
• Stomata
