Microbes in the Environment
"[The] ability to inactivate microbes in the environment on a continuous basis is important because bacteria, including MRSA, can survive in a variety of conditions for long periods of time and can spread via dust particles, clothing, furniture, or hospital equipment that have been in contact with infected patients..."

Daisy pollen (Helianthus sp.). The outer wall (exine) has many small spiky projections. The pollen gets caught in the body hairs of insects visiting the flower. Cross pollination occurs when insects fly to another similar flower and pollen is left behind. Pollen contains the male reproductive cells of a plant. When the pollen grain, containing the male gametes, lands on the stigma of a flower, it germinates. A pollen tube grows out from the germinal pore, down through the stigma, to the ovary. The male nuclei pass down the tube, fertilize the ovules and seed is formed. Humans can also be allergic to daisy pollen.
