Answer:

What are stinkhorns?  Stinkhorns are mushrooms that are found from the tropics to more temperate regions such as Wisconsin.  They can suddenly appear in mulch, lawns, and areas with bare soil.  These visually-shocking fungi get their common name from their characteristic, unpleasant odor.  Although they are often unwanted additions to home gardens, stinkhorns do not cause plant disease.  Because stinkhorns can grow on dead organic material, they actually are beneficial in that they contribute to the recycling of plant debris into nutrients that improve soil fertility and can be used by garden plants.

What do stinkhorns look like?  Stinkhorns grow into various shapes, but they are bestknown for looking like horns or penises.  A few species grow several appendages, resulting in an octopus-like appearance.  Some species have a veil attached below the cap that resembles a lacey skirt flowing from the mushroom’s hollow stalk.  Stinkhorns can range in color from white, beige, and olive to bright orange or red with black accents.  The tips of mature stinkhorns are usually coated in a spore-containing slime.  Gardeners often discover immature stinkhorns as they dig in the soil.  The immature forms appear as whitish to pink or purple, egg-shaped masses.  Stinkhorns develop rapidly sometimes growing up to four to six inches per hour, and can generate enough force to break through asphalt.

Where do stinkhorns come from?  Stinkhorns are often first introduced into a garden in organic materials (e.g., soils and mulches) that contain microscopic hyphae (i.e., fungal threads) of stinkhorn fungi.  Once stinkhorns mature, they produce a pungent, off-putting odor that is reminiscent of rotting flesh or dung.  This smell may disgust people, but it attracts insects, particularly flies.  Flies and other insects eat the slimy material at the tips of stinkhorns and carry spores in this slime to new locations as they move around in the environment.  In many ways, this process is comparable to the distribution of pollen by bees (but of course without the more appealing scents associated with most flowers).

Westkost [7]

Answer:

Endosteum plays an important role in bone repair, bone remodelling and appositional bone growth.

Explanation:

Endosteum consists of a soft and thin connective tissue that lines the cavity of femur and humerus. Some of the major functions of endosteum are as follows:

Bone remodelling: Endosteum can stimulate the bone resorption that leads to the formation of new bone from the outside.

Bone repair: Hematoma, at the time of bone injury causes the division of endosteal cells and helps in bone repair.

Appositional bone growth: Endosteum that line the osteoblast cell can secrete bone matrix and increases the bone diameter.
