The function of above-ground buttress (wall-like) roots in tropical trees is:
-To stop animal moving and attacking trees
-To provide more surface area for water and nutrient uptake
-To physically support the tree
-To have more xylem for water uptake
Give this one a try later!
to physically support the tree
Which one of the following is NOT a function of stems?
-communication between leaves and roots
-elevate reproductive structures
-exclude unwanted nutrients
-support leaves
-transport water and sugar
, Give this one a try later!
exclude unwanted nutrients
Three major tissue systems make up the plant bodies do NOT include:
-Ground tissue
-Vascular tissue
-Support tissue
-Dermal tissue
Give this one a try later!
Support tissue
Why do vascular plants have to 'pull hard' to bring water from the soil to the leaves?
-water is held by capillarity in the spaces between soil particles and plants must
overcome this force to get the water out of the soil
-moving water through the 'pipes' of the xylem creates frictional resistance that the
plants must overcome
-plants must lift the water against gravity
-all of the above
Give this one a try later!
all of the above
Which of the following is a FALSE comparison between the xylem and phloem:
-Xylem vessels are usually larger than phloem sieve tubes
-Xylem supplies water to the leaves; phloem transports food from leaves to the rest
-To stop animal moving and attacking trees
-To provide more surface area for water and nutrient uptake
-To physically support the tree
-To have more xylem for water uptake
