While out hiking in the woods, Ian sees several wild grapevines wrapped around some tree trunks and branches. He notices the broad leaves and curling, forking tendrils of the vines that loop around the tree branches. This makes him think about the factors that influence the way things grow. Which factors contribute to the way organisms grow and develop? Choose the three that apply.
genetics
size
response to stimuli
structures
access to resources
Chemicals that affect growth and development.
hormones
dormancy
auxin
tropism
hormone that speeds up the rate at which plant cells grow and controls a plant's response to light.

dormancy
auxin

Vivienne visits a botanical garden in a nearby city and sees a plant commonly called Touch-Me-Not. She touches the tip of the leaf of this plant, known as Mimosa pudica, with her finger and watches the leaves close. She later learns that chemicals trigger this reaction. Plants respond to stimuli in different ways. Grows toward light is an example of?
positive gravitropism
negative gravitropism
thigmotropism
phototropism
Which of the following is a genetic factor that affects an organism's growth?
Temperature
Nutrition
Genes inherited from parents
Amount of sunlight
How do environmental factors influence the growth of plants?
By altering their genetic makeup
By providing the necessary conditions for growth
By changing the color of the plants
They have no effect
Which of the following best describes how environmental factors and genetic makeup interact to determine the height of a human?
Environmental factors have no impact on height, which is determined solely by genetics.
Height is determined solely by environmental factors like diet and exercise.
Genetics set the potential for height, while environmental factors such as nutrition can influence whether this potential is reached.
Height is randomly determined and not influenced by genetics or environmental factors.
How can pollution affect the growth of organisms in an ecosystem?
By increasing their growth rate
By having no effect
By decreasing their growth rate or causing mutations
By improving their genetic makeup
What role does water play in the growth of plants?
It has no role
It acts as a genetic carrier
It is essential for photosynthesis and nutrient transport
It changes the genetic structure of plants
Which of the following environmental factors can cause stress that affects an organism's growth?
Genetic diversity
Social interactions
Extreme temperatures
Inherited traits
How does nutrition affect the growth of organisms?
It has no effect on growth
It only affects the organism's color
Adequate nutrition is necessary for proper growth and development
It changes the organism's genetic makeup
How do mutations affect an organism's growth?
They always result in positive growth
They have no effect on growth
They can either hinder or enhance growth, depending on the mutation
They prevent growth entirely
