What is the study of plants called?
Botany
Which tissue carries water upward in a plant?
Xylem
What is a plant’s growth response to a stimulus called?
Tropism
Which plants bloom when nights are longer?
Short-day plants
A plant bending toward a window is showing what tropism?
Phototropism
What type of plant completes its life cycle in one year?
Annual
A plant growing toward a light source is showing what type of tropism?
Positive Phototropism
What is a change in the environment that causes a plant to respond?
Stimulus
Which tissue carries food through a plant?
Phloem
What tropism is growth toward light?
Phototropism
Which plants bloom when days are longer?
Long-day plants
Roots growing downward is what type of gravitropism?
Positive gravitropism
What type of plant lives for more than two years?
Perennial
Roots growing downward into the soil show what tropism?
Positive Gravitropism
What is the main function of leaves?
To make food (photosynthesis)
Which type of plant has transport tubes?
Vascular plant
What tropism is growth in response to water?
Hydrotropism
What does “positive tropism” mean?
Growth toward a stimulus
A vine wrapping around a fence is what tropism?
Thigmotropism
What type of plant produces flowers and fruit?
Angiosperm
A plant growing toward water underground is showing what tropism?
Positive Hydrotropism
What part of the plant supports it and transports materials?
Stem
Which type of plant absorbs water through rhizoids?
Nonvascular plant
What tropism is growth in response to gravity?
Gravitropism
What does “negative tropism” mean?
Growth away from a stimulus
Why do roots grow toward water?
To absorb water (hydrotropism)
What type of plant produces cones instead of flowers?
Gymnosperm
A vine wrapping tightly around a pole is showing what tropism?
Positive Thigmotropism
What part of the plant absorbs water and anchors it?
Roots
Why are vascular plants able to grow taller than nonvascular plants?
They have transport systems (xylem and phloem)
What tropism is growth in response to touch?
Thigmotropism
What is a plant’s response to length of day and night called?
Photoperiodism
Why is a plant growing away from too much heat an example of?
Negative thermotropism
What is the main difference between vascular and nonvascular plants?
Vascular plants have transport tubes, nonvascular do not
A plant growing away from a harmful chemical is what type of response?
Negative chemotropism
