Eukaryotic kingdom dichotomous key 1a. no cell 1b. cell to 2 2a. has chloroplasts and a large central 2b. no chloroplasts or large central to 3 3a. has flagella and 3b. no flagella and question: using the dichotomous key, identify the kingdoms of cells a-d, and explain how you know the identity of each.

Dichotomous Key for Animal and Plant Cell, this is a kind of messy key, but it will give you an example of what to do. You're Welcome!
If you need more help with cytology, just ask me, I'm a A+ in Biology. 
1. Has a cell wall                                                           Go to number 2
    Has no cell wall                                                          Go to number 3
2. Has a central vacuole                                                Go to number 4
    Has no central vacuole                                        Than it can't be a plant or animal cell
3. Has a cell membrane                                                  Go to number 5 
    Has no cell membrane                                All eukaryotic cells have a cell membrane
4. Has chloroplasts
Has to be a plant cell because it has a cell wall, a central vacuole and chloroplasts 
    Has no chloroplasts                                     Than it can't be a plant or animal cell
5. Has a nucleus                                                          Go to number 6  
    Has no nucleus                                            Than it can't be a plant or animal cell
6. Has more than one lysosome                    Has to be an animal cell because it has no cell wall or central vacuole or chloroplasts and it has more than one lysosome. 
   Has only one lysosome                                    Plant cells only have one lysosome

Maybe haha
