Plant Tropisms
What is a plant’s growth response to light called?
Phototropism
What gas do plants take in for photosynthesis?
Carbon dioxide
What is the main purpose of cellular respiration?
To produce energy for the cell (ATP)
Name one example of a non-vascular plant.
Moss
The thorns of a cactus would be an example of which adaption? Survival, Defense, or Reproduction
Defense
Which tropism describes a plant’s roots growing downward due to gravity?
Geotropism/ Gravitropism
What part of the plant cell does photosynthesis?
Chloroplast
What gas do plants release during respiration?
Carbon dioxide
What do vascular plants have that non-vascular plants do not?
Tubes to transport water and nutrients — xylem and phloem
What plant part often adapts to attract pollinators?
Flowers
How does thigmotropism help a plant survive?
It helps the plant climb or cling to surfaces for support
Name the two products of photosynthesis
Glucose and oxygen
Where does respiration occur inside the cell?
Mitochondria.
Whats an example of a vascular plant?
Trees, bushes, grass, flowers
Name an adaptation of a plant that lives in a rainforest.
Large, broad leaves to capture more sunlight.
Give an example of a plant showing negative geotropism.
A stem growing upward against gravity
Write the basic equation for photosynthesis using words.
Carbon dioxide + water + sunlight → glucose + oxygen.
How is respiration related to photosynthesis
They are opposites. The products of photosynthesis are the reactants of respiration.
What is the job of xylem in a vascular plant?
Transport water
What type of plant adaptation allows seeds to travel by wind?
Lightweight or winged seeds.
A plant grows toward a water source underground. What two types of tropisms are involved?
Positive Hydrotropism and positive geotropism
Why is photosynthesis important to most living things on Earth?
It produces oxygen for animals to breathe and glucose for energy in food chains.
If a plant is sealed in a container with no sunlight, what will happen to its oxygen and carbon dioxide levels over time?
Oxygen will decrease and carbon dioxide will increase.
Which grow taller? Vascular or Non Vascular Plants
Why do venus flytraps capture insects?
Because they grow in poor soil.
