BIO-1116 Tutorial Lab 2 Terms Exam
Questions And Answers
What is the purpose of the spiral leaf arrangement in mosses? - answer retains water,
conduit for water
What is the function of rhizoids in moss? - answer anchorage to substrate
What is the function of the stem in moss? - answer support of leaves, storage of
nutrients, and some transport (diffusion)
Why do mosses grow in clumps? - answer rely on support from neighbouring plants,
able to retain water
Why is height growth so restricted in moss? - answer because there is no vascular
tissue, nutrients and water are transported by diffusion which only works short
distances
What type of support allow mosses to remain upright and tall? - answer some
sclerenchyma present, turgidity of the parenchyma, grows in clumps
Is there a cuticle present on the surface of the leaves in mosses? - answer yes, but very
thin
Do the leaves of mosses have stomata? - answer no
Why is fragmentation an inefficient means of reproduction? - answer requires an
external factor to initiate the process, doesn't produce many offsprings
What type of cell division occurs in the moss capsule? - answer meiosis
How does the moss sporophyte obtain its organic nutrients and water? - answer by
relying on the female gametophyte's seta and foot
What does the presence of flagellated male sperm cells suggest about the means of
gamete transfer? - answer requires water
In mosses, what advantage does the embryo have by being enclosed by the female
gametophyte? - answer embryo is easily protected and nourished
What is the main method of spore dispersal in mosses? - answer wind
Why is it advantageous for ferns to posses vascular tissue? - answer provides more
efficient transportation of material and support for the plant
What is the advantage of increased size in plants? - answer can obtain more nutrients
