A change in the environment that causes a plant to react is called a ___________________.
A change in the environment that causes a plant to react is called a STIMULUS.
What are the three main things plants need to survive?
Sunlight, water, and soil nutrients
__________________ carries water upward from the roots to the rest of the plant.
XYLEM carries water upward from the roots to the rest of the plant.
During ____________________, plants use sunlight, water, and carbon dioxide to make food.
During PHOTOSYNTHESIS, plants use sunlight, water, and carbon dioxide to make food.
How do plants and animals depend on each other?
What is: Plants provide animals with food and oxygen, while animals help plants by spreading seeds and pollinating flowers?
___________________ is the way a plant responds to light.
PHOTOTROPISM is the way a plant responds to light.
What are an example of a plant defense?
Thorns, spines, and bad-tasting chemicals
__________________ carries sugars made by the plant to other parts of the plant.
PHLOEM carries sugars made by the plant to other parts of the plant.
During ____________________, cells break down glucose using oxygen.
During CELLULAR RESPIRATION, cells break down glucose using oxygen.
How are the amounts of oxygen and carbon dioxide related to each other?
What is: Plants take in carbon dioxide and release oxygen, while animals breathe in oxygen and release carbon dioxide, creating a balanced cycle?
___________________ is the way a plant responds to gravity.
GRAVITROPISM is the way a plant responds to gravity.
What is the process called when plants use sunlight to make food?
Photosynthesis
Nonvascular plants absorb water and nutrients directly into their __________________.
Nonvascular plants absorb water and nutrients directly into their CELLS.
One important product of cellular respiration is ____________________, which gives cells usable energy.
One important product of cellular respiration is ATP, which gives cells usable energy.
Why don’t we run out of the important gases that we need to stay alive?
What is: Plants constantly produce oxygen while animals produce carbon dioxide, so these gases are continuously recycled and replaced in a never-ending cycle?
Some plants wrap around objects when they sense ___________________.
Some plants wrap around objects when they sense TOUCH.
How do some plants reproduce without using seeds?
Through runners, tubers, rhizomes, and bulbs
Vascular plants can usually grow taller because they have __________________ that move water and nutrients.
Vascular plants can usually grow taller because they have TISSUES that move water and nutrients.
What is transpiration in plants?
What is: The process where plants release water vapor from their leaves into the air, similar to how animals sweat?
DOUBLE JEOPARDY!!!!!!!! TIMES 2 POINTS!!!!
6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do these equations explain why the total amount of O2 and CO2 remains the same?
What is: The first equation shows plants using carbon dioxide to make oxygen during photosynthesis, and the second equation shows animals using that oxygen and releasing carbon dioxide back during respiration, so the gases stay balanced?
___________________ is the way a plant responds to touch.
THIGMOTROPISM is the way a plant responds to touch.
Which animal helps pollinate flowers while looking for food?
Bees, butterflies, and hummingbirds
