There are about 300–315 thousand species of plants, of which the great majority, around 260,000 are flowering plants. The rest are green algae, mosses etc.
158,000 new plant species will be discovered during your lifetime.
So far only two percent of plants have has been thoroughly screened or investigated for phyto-chemicals with potential medicinal uses.
There are about 80,000 edible plants in the world but few are widely marketed as food. Edible flowers include chrysanthemum, carnation, cattail, chicory, cornflower, canna, honeysuckle, nasturtium, and sunflower.
The world’s food supply depends on about 150 plant species. Of those 150, more than half of the world’s food energy comes from a limited number of varieties of three “mega-crops”: rice, wheat, and maize.
There are more than 600 known species of meat-eating plants. Most eat insects but some eat frogs or small mammals.
The roots of plants perform two main functions. First, they anchor the plant to the ground. Second, they absorb water and various nutrients dissolved in water from the soil.

Before seeds, plants used to reproduce through spores. The only living ancestors of these plants are ferns, horsetails, and lycophytes.
In plant growth, it has been observed that each successive leaf on the stems of many plants is turned from the previous leaf by the golden angle, approximately 137.5°, an angle that purportedly maximizes leaves' sun-collecting power.
'Anemious' is the word for a plant that grows in windy conditions. It is one of the rare words that contain all five vowels once each in the right order.
Plants lose gallons of water every day through the process of transpiration, the evaporation of water through the pores in their leaves.
In the late 80s NASA studied house plants as a means of providing cleaner and purer air for their space stations. They found Peace Lilies and Chrysanthemums to be the best all rounders at air filtering.
Resin from the Gympie Gympie, a plant common to rainforest areas in the north east of Australia, is so toxic and horrible to the touch it can drive animals and people to craziness – even suicide in the case of the man using the leaves 'for toilet purposes'.

Switzerland is the only country in the world that has recognized the dignity of plants in its constitution. The Swiss Constitution was amended in 2004 in response to growing concerns about the ethical implications of biotechnology. The Swiss government felt that it was important to explicitly state that plants, as living beings, deserve to be treated with respect.
Plants that are not cared for will cry for help. A thirsty plant will make a high-pitched sound that is too high for us to hear.
