6 FLOWER CHOICES OF BEES Bees choose flowers by color and scent. They are attracted to flowers by scents that are attractive to them. Flowers have patterns (nectar guides) that show bees where to look for nectar. Bees see blue-green, blue, violet, and ultraviolet. UV patterns create a landing zone attracting the bees to the nectary. When the nectar diminishes so does the attraction, and the bees move on to other flowers.

20 Pollen Young bees must consume large quantities of pollen in the first two weeks of their adult life. The consumption could last up to five days of age. 20

21 21 Pollen is a fine to coarse powder containing the microgametophytes of seed plants, which produce the male gametes (sperm cells). Pollen grains have a hard coat that protects the sperm cells during the process of their movement between the stamens to the pistil of flowering plants or from the male cone to the female cone of coniferous plants. When pollen lands on a compatible pistil of flowering plants, it germinates and produces a pollen tube that transfers the sperm to the ovule of a receptive ovary. The individual pollen grains are small enough to require magnification to see detail. POLLEN

24 24 Nursing duties are normally finished and field duties are undertaken when bees are days old. At the time the requirement for pollen decreases and the chief dietary need becomes carbohydrates. Carbohydrates are obtained from nectar and honey.

25 Nectar 25 Nectar is the sugar rich liquid produced by the flowers of plants in order to attract pollinating insects. It is also the principal raw ingredient of honey.

26 26 Although its main ingredient is natural sugar (i.e., sucrose (table sugar), glucose, and fructose), [4] nectar is a brew of many chemicals. For example, the Nicotiana attenuata, a tobacco plant native to the US state of Utah, uses several volatile aromas to attract pollinating birds and moths. The strongest such aroma is benzyl acetone, but the plant also adds bitter nicotine, which is less aromatic and therefore may not be detected by the bird until after taking a drink. Researchers speculate the purpose of this addition is to drive the bird away after only a sip, motivating it to visit other plants to fill its hunger, and therefore maximizing the pollination efficiency gained by the plant for a minimum nectar output.sucroseglucosefructose [4]Utahvolatilenicotine

27 Nectary Gland of a Flower The nectary is the gland that secretes nectar. It is usually located at the base of the f lower. This forces pollinators to brush against the flowers reproductive structures to reach it.

28 WATER 28 Honey bees will consume water daily It is best if the beekeeper supplies the water and not the neighbors swimming pool or horse trough. WATER JUG WITH STONES FOR BEES TO LAND ON POND
