• Response

• Reception

• Post Translational

Which of the following is NOT a type of stimulus that affects plants?

• Light

• Sound

• Electricity

• Chemicals

How do signaling molecules in plants behave differently from those in animals?

• They require blood to transfer

• They only act locally

• They are synthesized in large quantities

• They are inactive at resting positions

Which statement is true about plant based hormones?

• A single hormone can control all processes in a plant

• Hormones in plants need blood to be effective

• Multiple hormones can control a single process

• Hormones are only involved in the growth of plants

Which hormone is primarily responsible for cell elongation, branch growth, and the development of the vascular cambium?

• Cytokinins

• Gibberellins

• Auxin

• Ethylene

What is the main function of abscisic acid in plants?

• Seed germination

• Fruit ripening

• Slows growth, seed dormancy

• Cell division

Which hormone is known for its role in fruit ripening and as a stress hormone?

• Brassinosteroids

• Strigolactones

• Abscisic Acid

• Ethylene

What process is induced by cytokinins in plants?

• Leaf abscission

• Apoptosis

• Bolting

• Senescence

Which hormone promotes stem elongation and fruit growth, and is also involved in seed germination?

• Auxin

• Gibberellins

• Ethylene

• Cytokinins

What is the effect of photomorphogenesis on plants?

• It decreases plant growth.

• It has no effect on plants.

• It triggers plant growth, development, and photosynthesis.

• It only affects plant pigmentation.
