What kind of adaptation might be useful for a plant in a desert?

Answer explanation

Store large amounts of water

Spines to prevent predators from drinking water

Waxy skin to prevent water loss

Can shrivel or expand depending on rain

Which of the following plants grow on trees to help with sunlight absorption?

• MrLiphytes

• epiphytes

• absurdphytes

• biologyphytes

Which of the following environments would be better for bryophytes (non-vascular plants) and seedless plants?

• Moist/damp

• Dry/humid

• Any environment is good

A hormone that STIMULATES growth activity in plants is called a ___________ hormone

A hormone that INHIBITS growth activity in plant is called an ___________ hormone

Indoleacetic acid is an example of this type of stimulatory hormone. This hormone stimulates cell division and elongation in stems and roots

• ethylene

• cytokinin

• gibberellin

• auxin

This type of hormone inhibits growth and blocks CO₂ intake by closing the stomata

• cytokinin

• abscisic acid (ABA)

• gibberellin

• ethylene

This inhibitory hormone would be added to help ripen fruit since it weakens cell walls and breaks down complex carbohydrates into simple sugars

• ethylene

• abscisic acid (ABA)

• gibberellins

• auxins

This type of plant response is reversible and is NOT a growth response

• nastic response

• tropism

This type of tropism is where plants/vines wrap around objects that it comes into contact with

• phototropism

• hydrotropism

• gravitropism

• thigmotropism
