The scientific study of plants, known as </span><span style="font-size: large; text-decoration: none;">botany</span><span style="font-size: large;">, has identified about 350,000 </span><span style="font-size: large; text-decoration: none;">extant</span><span style="font-size: large;"> </span><span style="font-size: large; text-decoration: none;">species</span><span style="font-size: large;"> of plants. </span><span style="font-size: large; text-decoration: none;">Fungi</span><span style="font-size: large;"> and non-green </span><span style="font-size: large; text-decoration: none;">algae</span><span style="font-size: large;"> are not classed as plants.</span></div><div style="color: white;"><span style="font-size: large;">Most plants grow in the ground, with </span><span style="font-size: large; text-decoration: none;">stems</span><span style="font-size: large;"> above, and </span><span style="font-size: large; text-decoration: none;">roots</span><span style="font-size: large;"> below. Water and some nutrients come from the roots. The evaporation of water from pores in the </span><span style="font-size: large; text-decoration: none;">leaves</span><span style="font-size: large;"> pulls water through the plant. This is called </span><span style="font-size: large; text-decoration: none;">transpiration</span><span style="font-size: large;">.</span></div><div style="color: white;"><span style="font-size: large;">A plant needs </span><span style="font-size: large; text-decoration: none;">sunlight</span><span style="font-size: large;">, </span><span style="font-size: large; text-decoration: none;">carbon dioxide</span><span style="font-size: large;">, minerals and </span><span style="font-size: large; text-decoration: none;">water</span><span style="font-size: large;"> to make food. A green substance in plants called </span><span style="font-size: large; text-decoration: none;">chlorophyll</span><span style="font-size: large;"> traps the </span><span style="font-size: large; text-decoration: none;">energy</span><span style="font-size: large;"> from the Sun needed to make food. Chlorophyll is mostly found in leaves, inside </span><span style="font-size: large; text-decoration: none;">plastids</span><span style="font-size: large;">, which are inside the </span><span style="font-size: large; text-decoration: none;">leaf</span><span style="font-size: large;"> </span><span style="font-size: large; text-decoration: none;">cells</span><span style="font-size: large;">. The leaf can be thought of as a food factory. Leaves of plants vary in shape and size, but they are always the plant organ best suited to capture solar energy. Once the food is made in the leaf, it is transported to the other parts of the plant such as stems and roots. </span></div><div style="color: white;"><span style="font-size: large;">The word "plant" can also mean to put something in the ground.
