Question

1. match the plant tropisms with their respective definitions.

draggable item → corresponding item
thigmotropism → occurs when plants grow toward light, allowing leaves to capture more sunlight for photosynthesis
gravitropism → occurs when plants respond to touch, such as vines wrapping around a fence or pole for support
hydrotropism → occurs when plants respond to gravity, such roots growing downward into the soil and stems growing upward toward light
phototropism → occurs when plants grow in response to water, where roots grow toward moist areas to absorb more water for survival

Explanation:

• Thigmotropism: The term "thigmo-" relates to touch. So, plants responding to touch (like vines wrapping around a fence) is thigmotropism.
• Gravitropism: "Gravitro-" is related to gravity. Roots growing down and stems up due to gravity is gravitropism.
• Hydrotropism: "Hydro-" means water. Roots growing toward moist areas (water) is hydrotropism.
• Phototropism: "Photo-" means light. Plants growing toward light for photosynthesis is phototropism.

Answer:

• Thigmotropism → Occurs when plants respond to touch, such as vines wrapping around a fence or pole for support
• Gravitropism → Occurs when plants respond to gravity, such roots growing downward into the soil and stems growing upward toward light
• Hydrotropism → Occurs when plants grow in response to water, where roots grow toward moist areas to absorb more water for survival
• Phototropism → Occurs when plants grow toward light, allowing leaves to capture more sunlight for photosynthesis
