Multiple choice movement in plants living world of plants - plant physiology biology

Shock movement in Touch me not plant is

  1. Seismonasty

  2. Photonasty

  3. Chemonasty

  4. Thermonasty
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seismonasty or thigmonasty is the nastic movement induced in plants where the stimulus is touch. Touch-me-not plant, which has the scientific name as Mimosa pudica is sensitive to touch and is thus called as seismonastic.

Sleep movement of Papaya/Balsam is

  1. Autonomic movement

  2. Tropic movement

  3. Movement of locomotion

  4. Growth movement
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tropic movement is growth movement shown by plant in response to a unidirectional external stimulus. Leaves and leaflets shows nyctinastic movement, that is movement in night or in dark. This is also called as sleep movement. In this, the leaves become vertical during night. This is growth movement. Leaf shows daily rhythmic movement due to differential growth of upper and lower halves of the petiole. It is seen in papaya and balsam. 

Thus, the correct answer is option D.

Movements caused by internal factors are

  1. Paratonic

  2. Intrinsic

  3. Autonomic

  4. Rheotropism
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A movement shown by a plant part in response to an external factor is called as paratonic movement. In this, the direction of movement is controlled by the direction of the stimulus. Autonomic movement is the spontaneous movement of the protoplasm seen in aquatic plants due to internal factors. Growth of plant in response to the current of water is called as rheotropism.

Thus, the correct answer is option C.

Movement of plant part in response to touch is

  1. Seismonasty

  2. Thigmonasty

  3. Nutation

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nastic movements are responses of plant parts to stimuli. Seismonastiy is the nastic response of a plant to touch or vibration. Dropping of leaves of Mimosa pudica upon touching is due to seismonasty. Thigmonasty is the nastic response of a plant to touch. The movements of tentacles of Drosera when comes in contact with insect is due to thigmonasty. Nutation is the bending movements shown by some plant parts due to the unequal rate of growth of different parts of plants.  

Thus, the correct answer is option B.

Skototropic movements are induced by

  1. Night

  2. Light

  3. Touch

  4. Heat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Phototropism is the growth of plant part in response to lights. Aphototropism is movement of plant part away from the light. It is also called as negative phototropism. Skototropic movement is negative phototropism shown by vines in response to light.
Thus, the correct answer is option B.

Ongoing scanning at an almost unconscious level is ________.

  1. indirect scanning

  2. passive scanning

  3. active scanning

  4. directed scanning
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Scanning of opportunities is emerging as an important area in the topic of entrepreneurship. Continuous scanning of the operating environment needs to be done in order to stay competitive.

        Ongoing scanning at an almost unconscious level is called Passive Scanning. No effort is made to select a particular information to scan. It is a continuous process.
