What is behavoir

The way organism reacts to a change in the environment

100

what is stimuli

Any changes in an organism's environment that cause a change in behavior

100

Growth toward a stimulus is considered a

Positive Tropisim 

100

Growth away from a stimulus is considered a

 negative Tropism

100

What are plant horomons

Substances that act as chemical messengers within plants

200

What is Tropisim 

A response that results in plant growth toward or away from the stimuli 

200

What are the three types of potential stimuli

  • Light

  • Touch

  • Gravity 

200

what is phototropism

The growth of a plant towards or away from light

200

What is Photoreceptors

Chemicals in plants that allow it to detect light

200

What are auxins

Responsible for increased plant growth and play a part in positive phototropism

300

What direction do leaves and stems tend to grow

Towards the light. This allows them to maximize the amount of light they receive

300

Which part of the plant typically goes through negative phototropism

Roots

300

What is Thigmotropism

The positive or negative response of a plant to touch

300

what are Tendrils

Structures on plants that allow them to wrap around or cling on to objects

300

what are Ethylene

A gas that is produced by fruits, seeds, flowers, and leaves

400

Why might a trees growth look differently than the growth of a house plant

Because there is a even vs uneven distribution of sunlight

400

What plants are known to wrap around or cling to structures

Vines

400

When vines wrap around objects what type of thigmotropism is it

Positive thigmotropism

400

what is gravitropism

The response of a plant to gravity

400

what is Gibberellins

Present in rapidly growing areas of plants, such as roots and stems

500

Roots are an example of what type of thigmotropism

Negative thigmotropism

500

When roots grow TOWARD gravity it is 

positive Gravitropism

500

Three types of flowering responses are 

Long-day, Short-day, Day-neutral 

500

What are Flowering Plants

Plants that produce flowers in order to reproduce

500

What is Cytokinins

Increases the rate of cell division and slows the aging process of flowers and fruits
