Plant diversity, macroscopic structures Flashcards
rhizoids
structures that anchor bryophytes to a surface
vascular tissue
complex conducting tissue. Xylem and phloem
sporangium
enclosure in which spores are formed
calyptra
cap like covering of the fruit that detaches at maturity in flowering plants (enlarged archegonial venter protecting the capsule with the embryonic sporophyte)
spores
reproductive cell capable of developing into a new individual without fusion with another
adventitious roots
plant roots that form from nonroot tissue and are produced during normal development and nodal roots on strawberry
tap roots
primary root that grows vertically downward, gives of small lateral roots.
prothallus
gametophyte stage in the life of a pteridophyte

flowering plant with embryo bearing a single cotyledon. Parallel veins, leaves in multiples of 3
dicotyledonous
