One of the main differences between plants and animals, according to the Oxford University Press, is that almost any plant tissue can be regenerated in the correct cultures. The use of embryo cultures in plants helps seeds mature, grow faster, rescue a dying plant, produce large quantities of regenerable cells or create modified variations.
Lilies, azaleas, oleanders and cyclamens are all known for their showy flowers. These popular plants also have something else in common — they can cause serious illness and even death if your pet eats them. According to the Humane Society of the United States, more than 700 plants are toxic to pets. Symptoms of poisoning may range from nausea and vomiting to seizures and breathing difficulties. Some animals are more sensitive than others. Take a second look at the plants around your home to determine if they might be hazardous to your four-legged family members.
A new feature of HTML 5 is support for offline Web forms. This allows your computer to access an interactive Web form in the event of network disconnection. There are several categories of Web form files that HTML 5 can provide access to in offline mode. They each serve a distinct purpose and you should understand what each Web form file does before deciding whether or not to make it available offline.
The genus Juniperus provides landscapers with a huge assortment of plants for an array of functions. Some of the larger trees and shrubs stand out as specimen plants, while others serve as windbreaks, hedges and privacy screens. Smaller forms of juniper work as ground cover, preventing erosion on slopes and banks. Plenty of nonnative junipers adapt to North America to go along with the native types, giving you abundant options. These plants typically are cold hardy, with some able to withstand winters in frigid U.S. Department of Agriculture plant hardiness Zone 2.
Business transactions transactions can be small, such as buying and selling on a local consumer level, or they can be large, such as one company buying the global rights to a computer chip patent. Mergers are a type of financial transaction that can have major ramifications for customers, investors and workers.
A curriculum vitae, or CV, serves as a document for the presentation of a large volume of details such as your academic, research and affiliation information. With so much information to present, you should organize the CV in a way that makes it easy for the reader to digest. Including a license on your CV requires listing it in a separate section. In addition, include all the relevant details of your license to ensure that the reader easily recognizes your area of expertise.
For almost 40 million years, plant life on Earth was dominated by the lycophytes. During the Carboniferous era, about 354 to 290 million years ago, these seedless plants -- the oldest on the planet -- grew up to 115 feet tall. Today, only 10 to 15 genera of lycophytes remain. Plants in this family share common characteristics, including vascular stems and roots, reproduction through spores and small leaves with a single vein, called microphylls. Lycophytes are separated into three classes.
Horticulturalists, botanists and gardeners propagate certain plant species through budding, or methods of grafting in which vegetative buds of one plant are attached to another plant, known as rootstock. Budding, also known as bud grafting, is often employed in nurseries and greenhouses, though amateurs can do it themselves with a bit of practice. Budding can be used to combine cultivars from compatible species or create a clone of a single species.
Daphnes are small to medium-sized shrubs prized as foundation plants and for use in such scenarios as rock gardens. They generate fragrant flowers, with the different types producing blooms of various shades, depending upon the species or cultivar. Daphne shrubs have a reputation for performing well in shady sites, giving them versatility in the landscape. Cold hardiness is not a common trait in the daphnes, but several types exist for planting in U.S. Department of Agriculture plant hardiness zones warmer than zone 3.
There are two divisions of plants growing on land: vascular and non-vascular. Vascular plants are tracheophytes having stems and leaves containing vessels to carry water and nutrients through the plant. The vascular system is composed of the xylem, which carries water up from the roots to the leaves, and the phloem, which carries food down from the leaves to the roots. Non-vascular plants are bryophytes which absorb water and nutrients through the process of diffusion from environmental moisture. Both vascular and non-vascular plants use photosynthesis to produce energy. There are four broad categories of plants within the two divisions: mosses,…
Hidden within the thorny brambles or canes of blackberry plants are the luscious, jewel-like fruits of summer. To enjoy their own freshly picked blackberries, those without garden space might consider container gardening for blackberries, but the answer as to whether or not blackberries can be grown successfully in containers is a provisional one, depending on the plant, growing conditions and the gardener.
Brian Capon in "Botany for Gardeners" states, "In Nature's balance, the blessings the environment bestows on living things outweigh the afflictions capable of destroying them." Aerial shoot, or stem, modifications are Mother Nature's way of fulling a plant's basic needs. Five categories of aerial stem modifications are classified and can be used to better understand how plants survive in an unforgiving world.
Mealybugs are a major pest to numerous plants, trees and crops. These insects get their name from their white powdery appearance. Because they infest numerous types of plant hosts, gardeners must monitor their plants during the growing season for these pests and their damage.
American visas are issued by the State Department, which includes foreign U.S. embassies and consulates. There are different types of military visas available, and these visas are classified according to the length, nature and purpose of stay in the United States. Extensions are available for most types of visas
Veterans are individuals who spent time serving their country in the armed services. The years of service, willingness to put themselves in danger of injury or death, grueling training and surrender of liberty to protect their country gives military service a special significance. While departing under honorable circumstances gives the soldier special government benefits and recognition with future employers as a veteran, even soldiers that the military kicks out dishonorably deserve to call themselves veterans.
Herbicides and fungicides are two types of pesticides, aimed at reducing or eliminating the presence of plants and fungi harmful to desired plantings or crops. While there are other means of preventing unwelcome plants and fungi from growing, one common and fast-acting method uses chemicals that selectively inhibit growth or kill off specific species.
Limestone is a sedimentary rock composed mainly of calcium carbonate. Sedimentary rocks are formed when weather processes break down rocks into a fine material that eventually forms a sediment deposit. The sediment undergoes compaction and cementation over time, and eventually is turned into rock. Limestone is formed by both inorganic and biochemical processes.
Tress, bushes and shrubs all have one thing in common: they need to be pruned regularly to grow strong and healthy. If you would like to improve the appearance of your landscaping and outdoor space, then you should consider creating a pruning calendar for your plants and trees. A pruning calendar will help you keep track of when each plant or tree was last pruned, as well as when they should be pruned again. This system can help to make maintaining your outdoor space much simpler.
From the prairies of the Midwestern United States, to Rocky Mountain river banks and the Oregon Pacific Coast, the Lewis and Clark Expedition detailed plant life never before recorded by science or the white man.
With their shiny red berries and spiked, glossy leaves, holly marks the Christmas season, and is perhaps best known for being fashioned into wreathes and winter flower displays. The evergreen shrub comes in about 350 different species and is native to North America, Europe and Asia. Hollies are attractive and easy to grow, which makes them popular with gardeners. They are often seen in landscapes as foundation plantings, hedges, screens or accent plants.
