Pictures of Angiosperms

-
Mimosa
Feathery, fernlike leaves of the evergreen shrub Mimosa pudica curl inward when touched. Tiny, deep-pink flowers appear in the summer.








Mock Orange
The common mock orange, also called syringa, is a deciduous shrub covered with clusters of small, fragrant, cream-colored flowers. Syringa is the state flower of Idaho.









Musk Thistle
The musk thistle has decorative composite flowers but its spiny leaves and branches create a weedlike appearance. This species of thistle bears purple flowers and is common in fields in the northeastern United States.







Nail Polish Flowers
The nail polish plant, so-named because of the bright color of its flowers, belongs to the four-o’clock family. It grows best in sunny locations in fertile, well-drained soils.







Nightshade
All parts of the belladonna, or nightshade, Atropa belladonna, are poisonous. The drug atropine, used to dilate the pupils of the eyes, is one of several narcotics extracted from its leaves and roots.







Opium Poppy
The opium poppy’s green, unripe seed capsule, revealed when the flower petals drop, contains a milky sap that is the source of opium. To collect the sap, slits are made along the circumference of the seed capsules, enabling the milky sap to ooze out and dry. It is then scraped from the capsules, pressed into cakes, and dried to form the rubbery, yellow-brown opium. Natural derivatives of opium include morphine and codeine, used extensively in medicine as sedatives and pain killers. Heroin is a synthetic derivative of morphine. Morphine and codeine are habit forming. Heroin, which is especiallly addictive, is illegal in the United States.

Oxalis
Oxalis belongs to a group of subtropical and tropical tuberous or fibrous-rooted perennial or semievergreen plants commonly cultivated for their colorful flowers. Although some species are well suited for cultivation in rock gardens, others are considered invasive. In some cases the tubers and leaves are edible.






Passionflower
The passionflower, a close relative of the violets, is a woody-stemmed climbing plant that grows to a height of 10 m (30 ft). Passionflowers are cultivated for their unique flowers and edible fruits.








Peanut Plant
Although native to South America, the peanut plant is now cultivated in those parts of the United States, South America, Africa, and Asia having long, warm, growing seasons. A member of the pea (legume) family, the peanut is rich in protein, B vitamins, and oil. The plants themselves can be used as livestock feed.






Pear Tree
The pear tree is a member of the rose family. It is cultivated for its fruit throughout the cool, humid, temperate regions of the world. Pear juice is used in the production of a number of commercial fruit drinks.







Peony
Peonies have elaborate flowers, with five to ten petals and numerous stamens (male flower parts) and carpels (female flower parts). The plants are native to Europe, Asia, and the northwestern United States. Certain varieties are indigenous to wooded areas, while other varieties have been cultivated for decorative purposes in gardens.






Petunia
The petunia, a member of the nightshade family, is commonly cultivated as a garden plant. Petunias exist in a wide number of varieties, with flowers of different colors, shadings, and shapes.









Pimpernel
The pimpernel, cultivated for its flowers, grows best in sunny locations in moist, fertile soils. The blooms of certain species close at the approach of rainfall and open in bright sunshine. These species carry the nicknames shepherd’s barometer and poor man’s weatherglass.






Pineapple Mint
The pineapple mint is a perennial plant cultivated both as an ornamental and for its aromatic leaves, which are used as a culinary herb. It grows to a height of 45 cm (18in) and can become invasive in gardens.

Plant: Cell Structure And Function

-
Image
Plant Cell Plant cells contain a variety of membrane-bound structures called organelles. These include a nucleus that carries genetic material; mitochondria that generate energy; ribosomes and rough endoplasmic reticulum that manufacture proteins; smooth endoplasmic reticulum that manufactures lipids used for making membranes and storing energy; and a thin lipid membrane that surrounds the cell. Plant cells also contain chloroplasts that capture energy from sunlight and a single fluid-filled vacuole that stores compounds and helps in plant growth. Plant cells are surrounded by a rigid cell wall that protects the cell and maintains its shape. The tremendous variety of plant species is, in part, a reflection of the many distinct cell types that make up individual plants. Fundamental similarities exist among all these cell types, however, and these similarities indicate the common origin and the interrelationships of the different plant species. Each individual plant cell is at ...

Monocot and Dicot Seeds

-
Image
Monocotyledons (monocots) and dicotyledons (dicots) make up the two large groups of flowering plants, differentiated by their seed structures. Monocot seeds contain one cotyledon, or embryonic leaf. When these seeds germinate, the cotyledon remains below ground, absorbing nutrients from the endosperm, the starchy food supply in the seed. The coytledon transports these nutrients to the developing seedling. Dicot seeds contain two coytledons, which absorb and store the nutrients from the endosperm before the seed germinates. The cotyledons, thick with stored nutrients, emerge above ground during germination, and then transport the stored nutrients to the developing seedling. For a brief time, the cotyledons also serve as the first photosynthesizing leaves, but they wither and die when the true leaves emerge. related articles: flower flower variations in structure flower sexual reproduction flower pollination and fertilization flowering and the life cycle evolution of flowers angios...

Insectivorous Plants

-
Image
Insectivorous Plants, also carnivorous plants, plants that gain some of their nutrition from animals, especially insects, captured by the plants themselves. Most occur in bogs where the soil is acid and poor in available nitrogen; capturing insects is one way of getting nitrogenous compounds without manufacturing them. At the same time, the green leaves of these plants manufacture carbohydrates. The trapping mechanism of insectivorous plants is relatively small. Therefore, prey is almost inevitably limited to small insects. Insectivorous plants are diverse and represent members of three orders of dicots : Nepenthales, Scrophulariales, and Rosales. A majority are in the Nepenthales, including the pitcher plant , sundews and the Venus's-flytrap, and East Indian pitcher plants. Others include the bladderworts, butterworts, and the Australian pitcher plant. Discussed below are the sundews and bladderworts. Certain species of fungus are known to be carnivorous as well. Venus’s-Flytrap...
