Growth and Development of Plants

What is the process by which plants make their own food?

• Photosynthesis

• Respiration

• Transpiration

• Digestion

What part of the plant is primarily responsible for absorbing water and nutrients from the soil?

• Stems

• Leaves

• Flowers

• Roots

What is the term for the increase in size of a plant?

• Growth

• Decay

• Stagnation

• Diminution

Which hormone is primarily responsible for plant growth?

• Gibberellin

• Auxin

• Cytokinin

• Ethylene

What is photosynthesis and why is it important for plants?

• Photosynthesis is the method by which plants absorb nutrients from the soil.

• Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen, which is vital for their growth and for life on Earth.

• Photosynthesis occurs only at night when plants are dormant.

• Photosynthesis is the process of respiration in plants.

What are the two main types of plant growth?

• Root growth and leaf growth

• Lateral growth and horizontal growth

• Seasonal growth and perennial growth

• Primary growth and secondary growth

How do environmental factors like sunlight and water affect plant growth?

• Plants grow faster in the dark without water.

• Sunlight has no impact on photosynthesis in plants.

• Water is only necessary for flowering plants.

• Environmental factors like sunlight and water significantly affect plant growth by influencing photosynthesis and nutrient transport.

What is the role of roots in plant development?

• Roots are mainly responsible for flower production.

• Roots serve as the main site for gas exchange in plants.

• Roots primarily function for photosynthesis in plants.

• Roots are essential for anchoring, nutrient absorption, and energy storage in plants.

What is germination in the context of plant growth?

• Germination is when a plant absorbs nutrients from the soil.

• Germination is the process of a seed developing into a new plant.

• Germination is the stage where a plant begins to photosynthesize.

• Germination is the process of a plant producing flowers.

How do plants adapt to their environment to ensure survival?

• Plants rely solely on soil nutrients for survival.

• Plants adapt to their environment by modifying their structures and behaviors to optimize water usage, light absorption, and protection from threats.

• Plants can survive without any water or sunlight.

• Plants do not change their structures regardless of the environment.
