Plant Hormones

Front

What plant hormone is responsible for promoting cell elongation?

Back

Auxin

Front

Which plant hormone is known to cause the enlargement of fruits?

Back

Gibberellin

Front

What is the gaseous plant hormone that plays a role in fruit ripening?

Back

Ethylene

Front

In the context of plant hormones, what effect do gibberellins have on seed germination?

Back

Gibberellins promote seed germination by breaking dormancy and stimulating growth.

Front

What role does auxin play in phototropism?

Back

Auxin promotes cell elongation on the side of the plant that is away from the light, causing the plant to bend towards the light.

Front

How do ethylene levels affect leaf and petal drop in plants?

Back

Increased levels of ethylene promote the abscission of leaves and petals, leading to their drop.

Front

What is the primary function of gibberellins in plant growth?

Back

Gibberellins promote stem elongation, seed germination, and flowering.

Front

Which plant hormone is involved in the response to stress conditions, such as drought?

Back

Abscisic acid (ABA) is involved in stress responses, particularly in closing stomata during drought.

Front

What is the effect of auxin on root development?

Back

Auxin promotes root growth and development, particularly in response to gravity.

Front

How do gibberellins affect flowering in certain plants?

Back

Gibberellins can induce flowering in some plants, especially those that require specific environmental conditions.
