LABORATORY ACTIVITY ANGIOSPERMS-MONOCOTS: ALISMATALES, ASPARAGALES, LILIALES, ARECALES AND POALES I. OBJECTIVES After the activity, the student should be able to, i) describe the monocots, i) enumerate the orders comprising the monocots and ii) mention the economic importance of several monocots II. MATERIALS Live or herbarium specimen of monocots: Alismatales, Asparagales, iliales, Arecales and Poales; reproductive structures of any representative species for each group, any reference materials for angiosperms monocots, internet, newspapers, pencil, oslo paper, erasers, coloring materials III. INTRODUCTION The monocots are characterized as having parallel veins, scattered vascular bundles, and a single cotyledon. Alismatales, Asparagales, Liliales, Arecales and Poales are important orders. Many are food and oil sources and some are ornamentals. The order Poales includes the families Cyperaceae, Eriocaulaceae, Juncaceae, Poaceae, Restoniaceae, Sparganiaceae, Typhaceae…

Which angiosperm lineage includes the most species? a. magnoliids b. eudicots c. monocots d. water lilies
items in bullet are options for the question above it When gymnosperms arose during the late Carboniferous era, around 300 million years ago, they were the first true seed-bearing plants. The word comes from gymno-, meaning "naked," and -wsperm, which refers to "seeds" not actual sperm. Gymnosperms have "naked seeds," because they do not encase their seeds in fruits as do angiosperms. 1. Gymnosperms were also the first plants to develop pollen. Which of the following statements correctly describes one of the advantages of pollen? The development of pollen means that gymnosperms no longer require sporophytes for reproduction. The development of pollen means that gymnosperms are not dependent on water for reproduction. Pollen is created by the sperm of the plant. 2. In gymnosperms, where are the female gametophytes located? In the ovulate cones The gametophyte stage no longer exists in gymnosperms In the needles or leaves…
