CONCLUSION

Angiosperms (flowering plant) include in phylum Anthophyta.Angiosperms are plant that have flowers and fruit. Their part of the flower is a carpel which surrounds and protects the ovules and seeds. The fruit surrounds the embryo and aids seed dispersal. The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon), and pollen grains with a single groove while eudicots (true dicots) have two cotyledons, and pollen grains with three groove. Monocotyledons have leaf lamina with parallel vein. Their sepal, petal arranged in a series of 3s with adventitious root system only. Their vascular bundles scattered in cortex or irregular arrangement and they have no secondary development (non-woody and no annual rings).Whereas, dicotyledons have leaf lamina with netted vein. Their sepal, petal arranged in a series of 2, 4 or 5 with primary and adventitious root system. They have secondary growth in stem and vascular bundles extended via cambial activity (formation of ‘annual ring’ in cross section)

Based on the experiment diversity of angiosperms, the fixed slides is observed under light microscope, fresh specimens under direct observations, stereomicroscope and living specimens under direct observation with zero magnification. We will explore several fixed and fresh specimens of some selected angiosperms. Fixed slides under light microscope contributed by Helianthus sp, Hibiscus sp., Monocots stem (Monocotyledoneae), Dicots root (Dicotyledoneae), Monocots root (Monocotyledoneae), Triticum sp.root tip (‘wheat’, Monocotyledoneae), Capsella sp.carpel (Monocotyledoneae), Dicot leaf (Dicotyledoneae), Monocot leaf (Monocotyledoneae), Zea mays leaf (‘maize’, Monocotyledoneae),Fresh specimens under direct observation involved Vigna radiata Seedling and Sapling (‘kacang hijau,Dicotyledoneae), Zea mays Seedling and Sapling (‘jagung’,Monocotyledoneae),Crinum asiaticum Inflorescence...
