Plant Response Flashcard

Front

What is geotropism?

Back

Growth of a plant in response to gravity.

Front

What is phototropism?

Back

Growth of a plant in response to light.

Front

What type of response is phototropism?

Back

A plant growth response.

Front

Which hormone is primarily responsible for phototropism in plants?

Back

Auxin.

Front

What is an example of phototropism?

Back

A plant growing towards a window.

Front

Which part of the plant is most involved in phototropism?

Back

Stems.

Front

What is the role of auxin in plant growth?

Back

Auxin promotes cell elongation, particularly on the side of the plant that is away from light.

Front

How does gravity affect plant growth?

Back

Roots typically grow downward (positive geotropism) while stems grow upward (negative geotropism).

Front

What is the difference between positive and negative tropism?

Back

Positive tropism is growth towards a stimulus, while negative tropism is growth away from a stimulus.

Front

What environmental factors influence plant tropisms?

Back

Light, gravity, and water.
