    • What are angiosperms?  Angiosperms are the flowering, vascular and seed bearing plants  They produce seeds contained in fruits  The fruit is developed from the parts of reproductive structure, the flower  This group of plants is the dominant form of plant life on the planet  They are the major source of food for humans and other mammals  About 260,000 species are known http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Habit and Habitat The plants of this group are mostly shrubs, herbs, and most familiar trees They may be very large tress. e.g. Eucalyptus Or may be tiny plants. e.g. Duckweed (1mm in diameter) They are found everywhere except the polar regions, highest mountain tops, and the deep oceans They may occur as terrestrial plants, epiphytes, floating and rooted aquatics, parasites and saprophytes http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Euclayptus Duckweed http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Morphology Flower is the most significant part of the angiosperms It is the reproductive part of the plant which produces seeds http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Parts of the flowerMale Parts1. Stamen Made up of filaments and anther Produces pollens Number of stamens is usually same as the number of petals Anther Part of the stamen that produces and stores pollen It is usually found at the tip of a stalk Filament This is the stalk that the anther sits on top of http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Parts of the flowerFemale Parts1. Stigma Receives pollen from the male part2. Style Long stalk like structure between ovary and stigma3. Ovary Is usually found at the bottom of the flower Produces seeds inside and turns into fruit upon ripening4. Ovule The part of the ovary that becomes seed http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Carpel http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Other parts of flower Petals They are modified and colorful leaves of a flower They attract pollinators towards the flower Sepals They are also modified leaves but are green in color They cover the petals and protect them http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Evolution of Angiosperms The closest relatives of the angiosperms remain a mystery but the unique angiosperm flower probably evolved from an extinct angiosperm group that insect pollinated cones, combining male and female reproductive parts http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Evolutionary Adaptations1. The development of the flower The male and female structures are now in the same location on the plant, with a few exceptions, before in angiosperms, http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Evolutionary adaptations2. Pollination aided by biotic factors. Most plants have used abiotic factors such as water or wind. http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Evolutionary adaptations3. The development of a seed that contains energy as well as the development of a fruit for protection and dispersal Most of the fruits we eat allow the seed to be dispersed away from the parent plant http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Two kinds of flowering plants Monocots – Mono – meaning one Cotyledon - seed leaf http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Monocots Continued. Primary food source for much of the planet Whether we eat them or we feed them to other animals so we can eat the animals http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Monocots – even more Maiz Wheat http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Dicots Di – meaning two Cotyledon – seed leaf http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Dicots Most of our fruits and vegetables are dicots. Lots of energy here as well, but they usually don’t store. http://www.heavengb.com. The Biology Website. Visit and learn for free
    • Other dicots… Some that contain wood Some that don’t Lots that are in between. http://www.heavengb.com. The Biology Website. Visit and learn for free

    • 1- Apple (Malus domestica) Apple juice is used as anti-inflammatory for the digestive tract It decreases the acidity of the stomach Apple acts as both antidiarrheal and soft laxative Its juice helps to dissolve access fats, thus decreasing obesity It is also used to treat cough and bronchitis Decreases the risk of cancer, esp. of digestive tract Reduces fever Enhances the hearing ability Apple juice is a good skin conditioner http://www.heavengb.com.

    • 2. Grapes (Vitis vinifera)  Grapes are source of many essential metals (cobalt, iron) and vitamins (B1, B2,В6, В12)  Its juice has been used to treat metabolism disorders  Grapes are also beneficial in treating the disorders of liver, kidney, lungs as well as cardiovascular problems  This fruit is anti-inflammatory and laxative  Grapes help with nervous disorders, hypertension, high blood pressure and bronchitis  It helps to get rid of anemia  It has also been proved beneficial in treating tuberculosis http://www.heavengb.com. The Biology Website. Visit and learn for free
    • 3. Apricot (Prunus armeniaca) Contains vitamin B-17 and many other useful nutrients Decreases the risk of cancer Boosts the immune system It acts as a laxative and also adds in digestion It has been proved useful for treating anemia It is useful in treating respiratory disorders It treats the cough Apricot is used to make medicines for the skin diseases http://www.heavengb.com. The Biology Website. Visit and learn for free
    • 4. Pomegranate (Punica granatum) Pomegranate juice is cardio-protective, as it regulates the level of LDL and cholesterol Thus it is a good tonic for the heart It enhances the function of liver and kidneys It is a good laxative and also treats stomach inflammation It has been proved as anticancer and inhibitor against TB Its juice inhibits the replication of many viral genomes including herpes simplex virus Juice of pomegranate decreases fever due to its antiseptic properties It is also beneficial in diarrhea Biology Website. http://www.heavengb.com.
