Pollen - Study guides, Revision notes & Summaries

temperatures, food production will be destabilized by drought, air pollution will lead to an increase in allergies and asthma, and warmer waters and floods will increase the risk of waterborne diseases. Climate changes affect social and environmental health determinants such as clean air, ecosystem health, safe drinking water and sufficient healthy food. Temperature-related death and illness, extreme events, and polluted or stressed ecosystems represent important issues of increasing conc...

Define the following Terms: 1. Allergy: An excessive reaction that leads to an inflammatory response when a person comes into contact with a substance (allergen) to which he or she is sensitive. It is common immune response to substances such as pollen, animal dander, food, or dust. Also known as hypersensitivity. 2. Antihistamine: Drugs that stop histamines from attaching to histamine receptors in the tissues and producing inflammatory and allergic symptoms. This action counteracts the re...

Pre-lab 5: Introduction to Plant Diversity II Question 1. In contrast to Bryophytes, Lycophytes, and Monilophytes what specific advantage does pollen provide to seed plants in terms of their reproductive biology? Pollen is advantageous because it does not need water for the male cell to reach the female cell. Instead, pollinators transfer the different cells. Question 2. In contrast to Bryophytes, Lycophytes, and Monilophytes what specific advantage do seeds provide to seed plants in terms...
