FILL-IN-THE-BLANK
cotyledon 16. The "embryonic leaf" in the seeds of seed plants - some have 1 and others have 2.
suberin 17. The wax in the cell walls of cork tissue - also in the casparian strips of endodermal cells.
thallus 18. The simple, poorly differentiated, plant body that is the liverwort gametophyte body.
fiddleheads 19. The young, coiled leaves of ferns that are edible.
generative cells 20. The cells found in pollen grains that divide to produce sperm cells.
sori 21. The "fruit dots" that are clusters of fern sporangia.
protonema 22. The threadlike, first gametophyte stage of mosses.
guard cells 23. The cells which control the opening and closing of stomata.
Equisetum 24. This is the oldest living genus of vascular plants - we have 400 million year old fossils identical to modern species.
rhizome 25. This is a "horizontal main stem that runs underground" - mistaken for a root by stupid people.
TRUE-FALSE
F 26.  The food-conducting cells of some mosses that resemble phloem cells are called mycorrhizae.
F 27. Grains and legumes are two examples of simple fleshy fruit types in flowering plants.
T 28. Double fertilization is one characteristic of the life cycle of the angiosperm type plants.
F 29. Staminate cones of pines are usually found on the upper half of the tree, while the ovulate cones are generally restricted to the lower half.
T 30. Fibrous root systems are often common in the sod-forming grasses.               
T 31. Flowering plants of the division Magnoliophyta outnumber all other species of vascular plants combined.
F 32. As a general rule, the meiosis of plants is gametic, while the meiosis of animals is sporic.
T 33.  Polyembryony sometimes results in two or more embryos in the seeds of pine trees.
F 34. Secondary meristems of the plant body produce elongation, while primary meristems produce an increase in thickness of the plant body.
F 35. The simple, heart-shaped gametophyte of the fern life cycle is called the annulus.
