Duckweeds (water lenses) rank among the smallest plants in nature. The tiny green leaf is also called as “frond” and may be mistaken for algae. Excessive population growth of all the weed will reduce the oxygen level in a pond and can kill the fish and good algae. These plants fall under the family Lemnoideae. Duckweed is devoid of leaves and stems and has a very simple structure. Its population makes grow fast when there are a lot of nutrients present in the pond water. If there is organic matter available at the bottom of the plant in the form...

The plants belong to the family Lemnaceae, has a very simple structure, and are devoid of leaves and stem. Duckweed population spreads very fast and may double itself only in a matter of days.

Watermeal has no roots and looks like floating grass seed about the size of a pin-head. Duckweed and Watermeal reproduce by budding on the margin or base of the frond. Each frond can only do this a limited number of times before dying. Both survive freezing and...
