4 Written Questions

1. Kingdom of multicellular photosynthetic autotrophs that have cell walls containing cellulose e.g. mosses or ferns.
2. - to bring order to the study of millions of living organisms
   - help communication by agreeing on unique names
   - to show relationships between organisms and groups so that evolutionary pathways can be more easily established
   - the help the study of living things by placing them in groups with similar characteristics
3. When stromatolites began performing photosynthesis in stromatolites, it changed the air from anoxic to oxic. This meant life could never again start up the way it did, ,many anaerobic bacteria died, the ozone layer developed and cellular respiration began occuring.
4. a kingdom of eukaryotic organisms. They are heterotrophic and digest their food externally, absorbing nutrient molecules into their cells. Yeasts, molds, and mushrooms are examples.

3. The procaryotic cell has a nuclear region, but no true nucleus and ribosomes in cytoplasm, but no membrane bound organelles, they are smaller, older and live in extreme conditions. The Eucaryotic cell has a nucleus and other organelles mad from or bound by membranes and is bigger and lives in environments with plants and animals.
   1. age of the earth
   2. significance of cell membranes to origins of the earth
   3. differences between a procaryotic and eucaryotic cell
   4. importance of fossils

3 True/False Questions

1. significance of cell membranes to origins of the earth → When stromatolites began performing photosynthesis in stromatolites, it changed the air from anoxic to oxic. This meant life could never again start up the way it did, ,many anaerobic bacteria died, the ozone layer developed and cellular respiration began occuring.

   True        False

2. importance of fossils → By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments and even predict what may happen in the future.

   True        False

3. protists → a kingdom of eukaryotic organisms. They are heterotrophic and digest their food externally, absorbing nutrient molecules into their cells. Yeasts, molds, and mushrooms are examples.

   True        False
