Plants have existed on Earth for around 400 million years. The largest individual flower is the Rafflesia arnoldii, which can reach 1 meter wide and weigh 10 kg. Trees help soil by reducing erosion and creating suitable conditions for microorganisms, while grass can absorb hundreds of pounds of automobile exhaust pollution per acre. There are both male and female pine cones, with males being soft and small and females being the typical cones associated with pines.

2. The largest individual flower on Earth is from a plant
called Rafflesia arnoldii. Its flowers reach up to 1 metre
(3 feet) in diameter and weigh around 10kg.

3. Plants on the surface of the Earth have existed for around 400 million years.

4. Trees help our soil remain healthy by reducing soil
erosion and by creating a soil climate suitable for
microorganism to grow.

5. Around three quarters of the increase in CO2 levels from human activity over the last
20 years is from the burning of fossil fuels. The rest is made up largely of land use
changes such as deforestation.

6. One acre of grass can absorb and assimilate hundreds
of pounds of sulfur dioxide created by automobile
exhaust.

7. There are both male and female pine cones. Male pine cones are soft and small.
Female cones are the ones we generally associate with pine cones.
