How many plantes are there?

Answer 1

How many species of plants are there? We don't even know how many species there are. Somewhere between 20 million and 100 million different kinds, at the present time.

Plants occupy a wide variety of niches. The most common type of terrestrial plant today is grass, which is a flowering plant. Grass did not exist in the mesozoic (during the age of the dinosaurs) or before. Plants range in size from very tiny to giant sequoias, which are larger than whales. There are some even bigger plants than those.

Large parts of earth's surface are covered in desert, where the number of plants per acre is small. My guess is that counting each individual blade of grass as a separate plant (and many grasses grow in clumps or clusters from one root system or rhyzome), grasslands might have the highest average plant density. There are also many plants in the oceans. Plant density on the south pole would be the smallest, followed by Greenland and the north pole. Rain forests have plants living on plants. Alpine forests may have lots of baby trees in one area, but the big trees litter the ground with needles, so that one tree (and its lichens, mosses, and other plant parasites) will occupy many square feet.

If we assume an average of 10 plants per square foot over the entire surface of the earth, that gives us 5.5 quadrillion feet. So roughly 55 quadrillion plants, altogether, on our planet.
