Banana plantsBanana plants growing on a plantation. Each herbaceous trunk bears only one bunch of fruit and is cut down after harvest to encourage new growth from the rhizome (underground stem)
The banana plant is a gigantic herb that springs from an underground stem, or rhizome, to form a false trunk 3–6 metres (10–20 feet) high. This trunk is composed of the basal portions of leaf sheaths and is crowned with a rosette of 10 to 20 oblong to elliptic leaves that sometimes attain a length of 3–3.5 metres (10–11.5 feet) and a breadth of 65 cm (26 inches). A large flower spike, carrying numerous yellowish flowers protected by large purple-red bracts, emerges at the top of the false trunk and bends downward to become bunches of 50 to 150 individual fruits, or fingers. The individual fruits, or bananas, are grouped in clusters, or hands, of 10 to 20. After a plant has fruited, it is cut down to the ground, because each trunk produces only one bunch of fruit. The dead trunk is replaced by others in the form of suckers, or shoots, which arise from the rhizome at roughly six-month intervals. The life of a single rhizome thus continues for many years, and the weaker suckers that it sends up through the soil are periodically pruned, while the stronger ones are allowed to grow into fruit-producing plants.

The tiger (Panthera tigris) is a member of the genus Panthera and the largest living cat species native to Asia. It has a powerful, muscular body with a large head and paws, a long tail and orange fur with black, mostly vertical stripes. It is traditionally classified into nine recent subspecies, though some recognise only two subspecies, mainland Asian tigers and the island tigers of the Sunda Islands.
After a century of decline, overall wild tiger numbers are starting to tick upward. Based on the best available information, tiger populations are stable or increasing in India, Nepal, Bhutan, Russia and China. About 5,574 tigers remain in the wild, according to the Global Tiger Forum, but much more work is needed to protect this species if we are to secure its future in the wild. In some areas, including much of Southeast Asia, tigers are still in crisis and declining in number.
A road is a thoroughfare, route, or way on land between two places that has been surfaced or otherwise improved to allow travel by foot or some form of conveyance, including a motor vehicle, cart, bicycle, or horse. Roads have been adapted to a large range of structures and types in order to achieve a common goal of transportation under a large and wide range of conditions. The specific purpose, mode of transport, material[1][2] and location of a road determine the characteristics it must have in order to maximize its usefulness. Following is one classification scheme.
Access disruptions on roads following a disaster can cause significant social and economic losses. Risk informed infrastructure investment is critical to ensure the construction and maintenance of resilient road networks.
Plants tell time. Not the way we do – for example, it’s 3.40pm, time to pick up the kids. But like animals, plants can sense that winter is coming and it’s time to drop leaves.
A sunflower anticipates daybreak, much like a rooster does before starting to crow. At sunrise, sunflowers face east to greet the first rays and continue to move with the sun until it sets in the west. Overnight, the sunflower head swings back around so it faces east at dawn.
Dr Mike Haydon, a University of Melbourne plant scientist, says sunflowers only move until the flower bud opens. At that point they stop their daily dance and permanently face east. “This is where the controversy arises,’’ says Dr Haydon, from the School of BioSciences. “People say ‘my sunflowers don’t track the sun’. Well if they’re open sunflowers, then they don’t do that because that’s when they’ve stopped.”
Shaped like a shield, sap-sucking stink bugs are brown, green or mottled. They feed on a wide variety of edible plants, including various fruit trees and some ornamentals. Fruits become puckered, scarred and distorted as a result of the feeding. The eggs are light red to yellow-red and are found on the undersides of leaves. Read more about controlling stink bugs.
Somewhat flat in shape, squash bugs are dark brown or black and congregate at the base of plants or under dead foliage. They have piercing mouthparts that suck plant sap, causing yellow spots on leaves that will often later wilt, blacken, die and fall off. The eggs are long and yellow in color. Read more about controlling squash bugs.
Flying or jumping when disturbed, these small, thin, wedge-shaped insects come in shades of green, brown and yellow, depending on the species. Leafhoppers feed on a variety of edible and ornamental plants and cause leaves to lose color, turn brown and become stippled. They also leave behind black excrement. Read more about controlling leafhoppers.
Notorious for skeletonizing leaves of a wide variety of edible and ornamental plants, Japanese beetles have iridescent copper wings and a metallic-green thorax and head. Underneath they have small tufts of white hairs along the sides of their abdomens. The slightly curved, lawn-damaging larvae, also known as grubs, are gray-white with brown heads.
