Nutrition in plants

What is the process by which plants make their food using sunlight, carbon dioxide, and water?

• Sunlightation

• Waterification

• Chloroplastion

• Photosynthesis

Which pigment in plants absorbs light energy for photosynthesis?

• Chlorophyll

• Melanin

• Xanthophyll

• Carotene

What is the loss of water vapor from the aerial parts of plants called?

• Precipitation

• Evaporation

• Condensation

• Transpiration

In which part of the plant are stomata usually found?

• underside of leaves

• flower petals

• middle of stems

• top of roots

What is the main function of stomata in plants?

• Water absorption

• Gas exchange

• Seed dispersal

• Photosynthesis

What gas is taken in by plants through stomata for photosynthesis?

• Oxygen (O2)

• Nitrogen (N2)

• Hydrogen (H2)

• Carbon dioxide (CO2)

What is the primary function of chlorophyll in plants?

• Producing oxygen for respiration

• Capturing light energy during photosynthesis

• Regulating temperature in extreme conditions

• Absorbing water for hydration

Which organelle in plant cells is responsible for photosynthesis?

• Chloroplasts

• Nucleus

• Endoplasmic reticulum

• Mitochondria

What is the role of water in photosynthesis?

• Water helps in the production of glucose during the light-independent reactions.

• Water is responsible for the release of energy in the form of light during photosynthesis.

• Water is used as a source of carbon dioxide in the Calvin cycle.

• Water is split into oxygen and hydrogen ions during the light-dependent reactions, providing electrons for the photosystems and generating ATP and NADPH.

How does the process of transpiration benefit plants?

• Transpiration benefits plants by causing wilting, nutrient loss, and overheating.

• Transpiration benefits plants by reducing nutrient absorption, increasing water loss, and decreasing turgor pressure.

• Transpiration benefits plants by hindering growth, causing nutrient deficiency, and reducing water uptake.

• Transpiration benefits plants by facilitating cooling, nutrient uptake, and turgor pressure maintenance.
