Tactic, Nastic and Tropic

What is phototropism?

• The growth of an organism in response to gravity

• The growth of an organism in response to light

• The growth of an organism in response to temperature

• The growth of an organism in response to sound

Explain the process of gravitropism in plants.

• Plants respond to gravity by growing in a way that allows them to adapt to their environment.

• Plants respond to gravity by moving towards the sun.

• Gravitropism in plants is the process of responding to sound waves.

• Plants respond to gravity by growing randomly in all directions.

Give an example of thigmotropism in plants.

• Venus flytrap closing its leaves when triggered by an insect

• Sunflower turning towards the sun

• Cactus growing towards the light

• Dandelion seeds dispersing in the wind

What is chemotropism and how does it work?

• Chemotropism is the movement of an organism in response to sound

• Chemotropism is the movement of an organism in response to light

• Chemotropism is the growth of an organism in response to temperature

• Chemotropism is the movement or growth of an organism in response to a chemical stimulus.

Describe nastic movement in plants.

• Non-directional response to a stimulus

• No response to a stimulus

• Movement away from a stimulus

• Movement towards a stimulus

What is a tactic response in animals?

• A type of shelter built by animals

• A specific behavior or action used to gain an advantage over a competitor or predator.

• A type of food that animals prefer to eat

• A specific mating call used by animals

Give an example of a tactic response in animals.

• A lion roaring to establish dominance

• A peacock displaying its colorful feathers to attract a mate.

• A bird building a nest to attract a mate

• A rabbit freezing to avoid detection by a predator

Explain the concept of response in organisms.

• The reaction or behavior of an organism to a stimulus from its environment.

• The process of photosynthesis in plants

• The process of digestion in animals

• The process of cell division in organisms

How do plants exhibit tropic movements?

• By growth responses to external stimuli

• By producing seeds

• By undergoing photosynthesis

• By absorbing water through roots

What are the different types of tropic movements in plants?

• phototropism, thermotropism, aerotropism, chemotropism

• heliotropism, hydrotropism, geotropism, thigmotropism

• aerotropism, thermotropism, thigmotropism, chemotropism

• phototropism, geotropism, hydrotropism, thigmotropism, and chemotropism
