Chemotectic movement is a type of

  1. autonomic locomotion movement

  2. paratonic locomotion movement

  3. autonomic variation movement

  4. paratonoic variation movement


Correct Option: B
Explanation:

Chemotectic movement is paratonic locomotion movement as it requires an external stimulus for movement. Here, external stimuli is a chemical.

The movement in the staminal hairs of tradescantia is

  1. amoeboid movement

  2. rotation cyclosis

  3. circulation cyclosis

  4. oscillatory movement


Correct Option: C
Explanation:

The streaming movement in staminal hairs of tradescantia is circulation cyclosis movement.

Which of the following types of movements is exhibited by plasmodia of slime molds?

  1. Oscillatory movement

  2. Ciliary

  3. Streaming

  4. Amoeboid


Correct Option: D
Explanation:

Plasmodia of slime molds exhibit amoeboid movement.

The processes of apostrophe and epistrophe are associated with

  1. chemotectic movement

  2. thermotectic movement

  3. phototectic movement

  4. phototrophic movement


Correct Option: C
Explanation:

The processes of apostrophe and epistrophe are associated with phototectic movement. They are movements of chloroplasts in bright and weak light.

In blue-green algae oscillatoria, the apex moves sideways as the base of the algae is attached to a rock. Which type of movement is this?

  1. Streaming

  2. Amoeboid

  3. Ciliary

  4. Oscillatory


Correct Option: D
Explanation:

In blue-green algae oscillatoria, the apex moves sideways as the base of the algae is attached to a rock. This type of movement is called oscillatory movement.

The swimming movement of the antherozoids towards the archegonial tip in response to sugar is an example of

  1. thermotectic movement

  2. chemotectic movement

  3. phototectic movement

  4. chemotropism


Correct Option: B
Explanation:

The swimming movement of the antherozoids towards the archegonial tip, in response to sugar, is an example of chemotectic movement. Here, sugar acts as a chemical stimuli.

What happens in thigmotropism movement?

  1. Movement of curvature, in which a plant organ, i.e. roots, turn away from water current

  2. The movement of plants, in response to touch or physical contact

  3. Plant movement in response to one sided injury

  4. Plant movement, in which the organs of plants track the sun across the sky


Correct Option: B
Explanation:

The movement of plants in response to touch or physical contact is known as thigmotropism.

The bending of an organ, such as petioles, leaves, and peduncles towards the ground, not due to gravity, is called

  1. hyponasty

  2. epinasty

  3. nyctinasty

  4. haptonasty


Correct Option: B
Explanation:

The bending of an organ, such as petioles, leaves, and peduncles, towards the ground, not due to gravity, is called epinasty.

Which of the following is not an autonomic locomotary movement?

  1. Ciliary

  2. Oscillatory

  3. Cyclosis

  4. Nastic


Correct Option: D
Explanation:

Nastic movement is an autonomic growth movement.

Rapid plant movement in response to insect stimuli is observed in

  1. mimosa pudica

  2. telegraph plant

  3. bladderwort

  4. sandbox tree


Correct Option: C
Explanation:

Bladderwort exhibits rapid plant movement in response to insect stimuli.

The curvature movement of plants due to the external stimulus of sunlight is known as

  1. hydrotropism

  2. phototropism

  3. thigmotropism

  4. geotropism


Correct Option: B
Explanation:

The curvature movement of plants due to external stimulus of sunlight is known as phototropism.

Which of the following plant organs show(s) thigmotropism?

  1. Shoot apex

  2. Root apex

  3. Tendrils of climbers

  4. Leaf apex


Correct Option: C
Explanation:

Tendrils of climbers, like cucurbits, exhibit thigmonastic responses.

What kind of tropisms are observed in stems and roots, respectively?

  1. Negative geotropism and positive geotropism

  2. Positive geotropism and negative geotropism

  3. Negative phototropism and positive phototropism

  4. Negative phototropism and negative geotropism


Correct Option: A
Explanation:

Stem is negatively geotropic and root is positively geotropic.

Which of the following plants exhibits dancing movement?

  1. Oxalis

  2. Indian telegraph plant

  3. Mimosa pudica

  4. White mulberry


Correct Option: B
Explanation:

Indian telegraph plant exhibits dancing movement. The lateral leaves are always in rotatory movement during the day time.

Which movement is found only in dead parts of the plants?

  1. Nyctinastic movement

  2. Geotropic movement

  3. Hydrotropic movement

  4. Hygroscopic movement


Correct Option: D
Explanation:

Hygroscopic movement is found only in dead parts of the plants, which are hygroscopic in nature and result either due to loss or gain of water by them from the atmosphere.
