In a mycorrhizal association, the fungal mycelia use their extensive network of hyphae and large surface area in contact with the soil to channel water and minerals from the soil into the plant. In exchange, the plant supplies the products of photosynthesis to fuel the metabolism of the fungus. Ectomycorrhizae (“outside” mycorrhiza) depend on fungi enveloping the roots in a sheath and a net of hyphae that extends into the roots between cells.

Bees are also drawn to flowers by nectar guides, which are patterns on the petals that direct them to the center of the flower where the pollen and nectar are located. Nectar guides resemble a bull’s-eye or stripes near the flower’s center, and they often involve UV coloration. Bees and wasps usually sting in defense of their colonies, and thus social bees and wasps are more likely to sting than their solitary counterparts, especially near their hives. Most wasp stings occur because wasps are attracted to sweet foods and their nests are hidden. Flowers can be arranged singly or in clusters attached to a central stem.

Use these resources to teach students about the regional economies found throughout the world. Sometimes, water rights include the amount of water a consumer is allowed to use. Arid area found near the Tropic of Cancer and the Tropic of Capricorn, formed by the circulation of air masses. Small flow of water flowing naturally from an underground water source. Method of agriculture where trees and shrubs are cleared and burned to create cropland. Dry land on the side of a mountain facing away from prevailing winds.

Nonvascular plants lack a water-conducting system of tubular cells , and do not have true roots, stems and leaves. Like algae and fungi, the plant body of some nonvascular plants is often called a thallus. Nonvascular plants are all placed in the Division Bryophyta, including the mosses and liverworts. The vast majority of the plant kingdom are vascular, with tubular, water-conducting cells called xylem tissue. Like a microscopic pipeline system, they are arranged end-to-end from the roots to the leaves. Unlike nonvascular plants, they have true roots, stems and leaves.

For all of these plants, one of the biggest risks is frost. Because they bloom in the spring, a late frost could kill their flowers before the plants are successfully pollinated. Another risk is that many pollinators, such as bees, often have not had a chance to build up their populations by the time these early blooming plants flower. Therefore, spring bloomers for businesses facing complex and turbulent business environments, which of the following is true? run the risk of not getting enough visits from pollinators to reproduce. This information will be instrumental background knowledge as you educate others about the role and value of native pollinators in farm and garden environments. Table 7 summarizes traits of a good pollinator and provides examples of pollinators that have or lack each trait.

This species typically grows on outcrops of serpentine in the Coast Ranges of central and northern California. It varies in color from creamy white and shades of green to black. In California, many species of rare and endangered plants are endemic to serpentine outcrops. Genetic drift has undoubtedly occured in isolated cypress groves such as this one, which are often referred to as “arboreal islands.” New evidence from DNA sequencing has further complicated the number of cypress species, including the transfer of other conifer genera into the genus Cupressus.
