flowering plants show sexual reproduction. A look at the diversity of structures of the inflorescences‚ flowers and floral parts‚ shows an amazing range of adaptations to ensure formation of the end products of sexual reproduction‚ the fruits and seeds. In this chapter‚ let us understand the morphology‚ structure and the processes of sexual reproduction in flowering plants (angiosperms). 2.1 FLOWER – A FASCINATING ORGAN OF ANGIOSPERMS Human beings have had an intimate relationship with flowers

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

ALMONDS IN WATER BEFORE CONSUMING? Dry almonds contain an enzyme inhibitor in the skin which is basically meant to protect the seed till it gets moisture for germination. When the almonds are soaked in water this enzyme inhibitor is released. Eating pre-soaked almonds is easier to digest and also makes more nutrients available for digestion. In fact‚ most nuts and seeds are easier to digest and have better nutrient availability

Just as humans have essential needs for survival‚ all plants require several basic elements to grow and thrive‚ including… Soil minerals (the more nutrient-rich the soil‚ the better the plant will grow) Water Air (carbon dioxide‚ hydrogen and oxygen) Sunlight Proper soil temperature Proper air temperature How much a plant needs of each element initially depends on the plant’s original habitat. For example

studies have asserted that phenotypic traits such as shade tolerance‚ rapid growth‚ high rates of photosynthesis and its wide tolerance of moisture and drought have aided R. cathartica’s success as an invading species. In addition to so‚ its high germination rates and high fecundity‚ bird dispersed fruit and secondary metabolite production have also contributed to its ability to rapidly increase in abundance and its impacts on the invaded ecosystem.

EXERCISE 5 PHYTOGRAPHY: THE FRUIT Name: JOHN REY CORPUZ Score: Date:APRIL 2‚ 2013 Section: I. INTRODUCTION The fruit is a matured ovary containing one or more seeds. It is composed of the exocarp‚ mesocarp and the endocarp. Many floral parts aside from the ovary are persistent and therefore could still be seen in mature fruits. Some examples are the receptacles (apple‚ sepals (eggplant)‚ style (corn) and many more. There are several variations of the

Known to many as japgrass‚ cogongrass was accidentally introduced into Alabama near Grand Bay about 1911 as seed in packing materials from Japan (4). Purposeful introductions soon followed in other areas of Alabama‚ Mississippi‚ and Florida‚ with the primary intent for forage production (1‚4). Horticultural varieties of cogongrass continue to be sold under the
