What is the specialized joint responsible for the rapid movement of leaflets in leguminous plants?
- A. Pulvinus
- B. Stipule
- C. Node
- D. Phloem
- Answer: A. Pulvinus
- Explanation: The pulvinus is the specialized joint at the base of leaflets that orchestrates rapid movements.
Which term refers to the unique movement in leguminous plants triggered by touch or mechanical disturbance?
- A. Seismonastic movement
- B. Phototactic movement
- C. Epinasty
- D. Nutation
- Answer: A. Seismonastic movement
- Explanation: Seismonastic movement is the rapid response triggered by touch or mechanical stimuli.
Which leguminous plant is renowned for its rapid leaf-folding in response to touch?
- A. Sunflower
- B. Venus flytrap
- C. Mimosa pudica
- D. Morning glory
- Answer: C. Mimosa pudica
- Explanation: Mimosa pudica, also known as the sensitive plant, exhibits rapid leaf-folding upon touch.
What role do motor cells play in the rapid movement of leaflets in leguminous plants?
- A. Photosynthesis
- B. Turgor pressure changes
- C. Pollination
- D. Transpiration
- Answer: B. Turgor pressure changes
- Explanation: Motor cells undergo changes in turgor pressure, facilitating the movement of the pulvinus.
Why does Mimosa pudica display rapid leaflet movement?
- A. Attracting pollinators
- B. Herbivore deterrence
- C. Enhancing photosynthesis
- D. Water conservation
- Answer: B. Herbivore deterrence
- Explanation: The rapid movement deters herbivores and protects the plant.
Which environmental stimuli can trigger the rapid movement of leaflets in leguminous plants?
- A. Light changes
- B. Temperature fluctuations
- C. Mechanical disturbances
- D. All of the above
- Answer: D. All of the above
- Explanation: Leguminous plants respond to various stimuli, including light changes, temperature fluctuations, and mechanical disturbances.
What is the primary function of the pulvinus in leguminous plants?
- A. Nutrient storage
- B. Rapid movement coordination
- C. Water absorption
- D. Photosynthesis
- Answer: B. Rapid movement coordination
- Explanation: The pulvinus coordinates rapid movements through turgor pressure changes.
How does the rapid leaflet movement contribute to herbivore deterrence?
- A. By attracting predators
- B. by startling herbivores
- C. By releasing toxins
- D. By mimicking other plants
- Answer: B. By startling herbivores
- Explanation: The sudden movement startles herbivores, discouraging them from feeding.
What term is used to describe the overall adaptability of leguminous plants in response to environmental changes?
- A. Seismonasty
- B. Environmental sensitivity
- C. Botanical ballet
- D. Adaptation
- Answer: D. Adaptation
- Explanation: Leguminous plants exhibit adaptation in response to environmental changes.
Which plant part is directly affected by the rapid movement in leguminous plants?
- A. Stem
- B. Root
- C. Leaflet
- D. Flower
- Answer: C. Leaflet
- Explanation: The rapid movement occurs in the leaflets, controlled by the pulvinus.
What does the term "seismonastic" specifically refer to in leguminous plants?
- A. Rapid leaf unfolding
- B. Touch-induced movement
- C. Flower blooming
- D. Phototactic response
- Answer: B. Touch-induced movement
- Explanation: Seismonastic movement is specifically triggered by touch or mechanical stimuli.
Which of the following is not a function of the pulvinus in leguminous plants?
- A. Coordinating rapid movements
- B. Energy conservation
- C. Nutrient storage
- D. Photosynthesis
- Answer: D. Photosynthesis
- Explanation: The pulvinus is not directly involved in photosynthesis.
What purpose does the rapid leaflet movement serve during unfavorable conditions?
- A. Maximizing exposure to stressors
- B. Optimizing resource utilization
- C. Preventing water loss
- D. Energy conservation
- Answer: D. Energy conservation
- Explanation: Rapid movement helps conserve energy during unfavorable conditions.
In Mimosa pudica, what does the folding of leaflets signify during the evening or in response to touch?
- A. Pollination readiness
- B. Water conservation
- C. Defensive mechanism
- D. Exposure to sunlight
- Answer: C. Defensive mechanism
