The function of sporopollenin is to protect the pollen grains from external damages such as rain,high temp. Sporopollenin forms the outercovering of the exine & it is the most resistant organic material on the Earth ever known.
Where do algae blooms occur?
Algae and cyanobacteria can form blooms Algae and cyanobacteria can rapidly grow out of control, or “bloom,” when water is warm, slow-moving, and full of nutrients. Blooms can occur in fresh water, marine (salt) water, and brackish (a mixture of fresh and salt) water around the world.
Where are zooplankton found?
Where are freshwater zooplankton found? Freshwater zooplankton are found in the water in wetland areas such as lakes, tarns, streams and swamps. They are most abundant nearer the surface as they eat phytoplankton (microscopic plants) which need light to photosynthesise. Many species move into shallower waters at night.
