When ripe pollen from an anther of the same kind of flower catches on the stigma, each pollen grain sends out a tiny threadlike tube. The tube grows down through the style and pierces one of the ovules in the ovary. This process is called fertilization. Each ovule must receive the contents of the pollen tube before it can develop into a seed. It usually takes the tube from two to five days to reach…

This drawing shows a lily cut open down one side. The sticky stigma at the top has caught a pollen grain. The grain will send a pollen tube down through the pistil of the style, into the ovary, and then upward into the center mass, called the ovule. The male cell carried by the pollen grain down the pollen tube will join the female cell in the ovule. After this fertilization takes place, the seed will soon form." data-credit="Encyclopædia Britannica, Inc." data-media-type="IMAGE" href="https://kids.britannica.com/students/article/flower/274354/media?assemblyId=53333" title="fertilization"></a>

the process by which excess

water from plants are removed to the atmosphere by the plants is known as transpiration

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil.

A canopy is defined as the uppermost trees, or branches of the trees, in a forest, forming a more or less continuous layer of foliage. A canopy is the topmost layer of bioactivity in a forest setting.

A canopy is the portion of a plant community found above ground formed by the crowns of individual plants. Within the garden, the canopy is where you will most likely find both the fruits of plants (the edible portion), as well as the insects that prey on those fruits and the plants’ leaves. However, a canopy can also refer to a physical structure raised to provide shade or to block rainfall or other precipitation in a particular area.

1. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point. 
2. A real image is that image which is formed when the light rays coming from an object actually meet each other after reflection or refraction.
3. A real image can be obtained on the screen.
4. The real image is always inverted.
5. The common example of real image is the image formed on the cinema screen.

• DO NOT pour fat from cooking or any other type of fat, oil, or grease down the sink. Keep a “fat jar” under the sink to collect the fat and discard in the solid waste when full.
• DO NOT dispose of household chemicals or cleaning agents down the sink or toilet. Simsbury has a Hazardous Waste Collection day usually from 8:00am to 1:00pm at Henry James School. Connecticut Resource Recovery Authority lists all collection dates.
• DO NOT flush pills, liquid or powder medications or drugs down the toilet. For recommendations on proper disposal for all types of medical wastes, visit the CT DEP publication here.
• Avoid using the toilet as a wastebasket. Most tissues, wrappers, dust cloths, and other paper goods should be properly discarded in a wastebasket. The fiber reinforced cleaning products that have become popular should never be discarded in the toilet.
• Avoid using a garbage disposal. Keep solid wastes solid. Make a compost pile from vegetable scraps.
• Install a water efficient toilet. In the meantime, put a brick or 1/2 gal container in the standard toilet tank to reduce water use per flush.
• Run the dishwasher or clothes washer only when you have a full load. This conserves electricity and water.
• Use the minimum amount of detergent and/or bleach when you are washing clothes or dishes. Use only phosphate free soaps and detergents.
• Minimize the use of pesticides, herbicides, fertilizers. DO NOT dispose of these chemicals, motor oil, or other automotive fluids into the sanitary sewer or storm sewer systems. Both of them end at the river.
• If your home has a sump pump or cellar drain, make certain it does not drain into the sanitary sewer system. If you are unsure, please call Simsbury Water Pollution Control at (860) 658-1380 and we can assist in determining the discharge point.

The hand moves in various and complicated ways and there is a complex array of articulations that allow flexibility of movement. The joints of the hand and wrist include hinge, gliding, condyloid and saddle joints. A hinge joint allows movement back and forth. In a gliding joint, the two surfaces of the bones are nearly flat. In a condyloid joint, an ovoid surface is received into an elliptical cavity. In a saddle joint, the opposing bone surfaces are concave-convex.

Fingers

The joints of the fingers (interphalangeal articulations), including the thumb, are hinge joints that allow for flexion and extension only.

Proximal Knuckles

The knuckles of the hand or metacarpal-phalangeal joints (MCP) are condyloid joints that allow flexion and extension as well as limited lateral deviation.

The Wrist and Palm

The internal joints of the wrist and palm (metacarpal-carpal and inter-carpal joints) are sometimes classified as gliding joints. The wrist and hand are better understood as an irregular collection of gliding, condyloid, and saddle joints allowing for the complex motions of the wrist, which includes varying combinations of flexion, extension and lateral deviation.

The joint between the carpal and metacarpal bones of the thumb (where the thumb joins the wrist) is the classic example of a saddle joint.

The Wrist and Arm

The wrist has a condyloid joint between the radius, ulna and carpal bones allowing for smooth movement in flexion, extension, and lateral deviations.

A plant of a group that comprises those that have seeds unprotected by an ovary or fruit, including the conifers, cycads, and ginkgo.

When the object is close to a convex lens (closer than the focal length of the lens), the lens behaves as a magnifying glass.

A virtual image is one which cannot be formed on a screen as the rays of light do not actually meet after passing through the lens. This happens when the object is closer to the lens than its focal length.

The lens is not powerful enough to bring the light to a focus behind it, so to see the image you have to look through the lens. The image formed will be erect (the same way up as the object), virtual and magnified.

The closer to the focal length the object is the greater the magnification will be. This is why magnifying glasses only work when they are placed at the right distance from the object being viewed.
