Do your best and ask questions about anything that you don't understand BEFORE you write the unit test. 6.1 Introduction to Plants Why are plants so important? If plants hadn't evolved to _________________, life on this planet would be very different. Plants _________________________________, and the most important waste product of this process is _________ - something that most of the animal life on this planet can't live without! As the first plants began photosynthesizing, the amount of __________ in the _________________. Some of the oxygen in the ______________________________________ ______. Eventually there was enough ozone in the upper atmosphere to effectively ________ the ____________________ that are highly destructive to living organisms. This allowed organisms to _______________________________________. Having an abundant supply of oxygen in the atmosphere also allowed other organisms to __________________________________________ _______________________________________________________________. This yields much ______________ than can be obtained in an atmosphere without oxygen. Plants are also ___________________________ because they form the basis of _____________. Most plants are ___________, creating their own food using _____________________________ through a process called _______________. Some of the earliest fossils found have been aged at ______________.
