Plant Nutrition 1
Plants need to absorb TWO things to be able to perform photosynthesis.
Name ONE thing for 100 points. Name BOTH things for 200 points.
Water and minerals
True or false: Carbon dioxide enters the leaves through phloem.
False (Carbon dioxide enters the leaves through STOMATA.)
True or false: Hormones regulate processes such as growth, leaf shedding, and fruit ripening.
TRUE
True or false: Crude sap moves around the plant and reaches every single cell using conductive vessels called phloem.
False (PHLOEM sap moves around the plant and reaches every single cell using conductive vessels called phloem)
True or false: Phloem sap is a watery fluid containing sugars while crude sap is a mixture of water and minerals.
TRUE
If plants move TOWARD the stimulus, we call it ______ tropism. If plants move AWAY from the stimulus, we call it ______ tropism.
positive; negative
Conductive vessels called ______ take crude sap to the leaves.
xylem
Leftover water from photosynthesis is released into the environment as a vapor in a process called ______.
Transpiration
______ is when some carnivorous plants close their leaves when they detect an insect has landed on them.
a) thermonasty
b) photonasty
c) thigmonasty
Thigmonasty
(Bonus points for correct teams: Can you explain photonasty or thermonasty?)
Cell respiration takes place in what organelle?
(Double points! +800 points for right answers and -800 points for wrong answers)
Mitochondria
After photosynthesis and cell respiration, what THREE substances do plants release through their stomata? Name ALL THREE to get points.
CO2, oxygen, water vapor
True or false: PHOTOtropism is the reaction to GRAVITY. HYDROtropism is the reaction to WATER. GEOtropism is the reaction to LIGHT.
False (PHOTOtropism is the reaction to LIGHT. HYDROtropism is the reaction to WATER. GEOtropism is the reaction to GRAVITY.)
