Ho Ho Ho.
biochemist here.
your missing a hell of alot of organells classicaly found in microbes of the eukaryote (with a nucleous) kind.
Example: endoplasmic reticulum -internal transport system and vastly more efficient protein production system-
Golgy Organell: A protein modification Organell that allows you to modify proteins and allows more complex ones to be created
You could also just nick some Chloroplasts -the light absorbing molecules in Chlorophyl- that will allow you to harness light for energy, albeit at a slow and inefficient rate, untill you evolve Chlorophyl to be more efficient. Right now you should up your mitochondria in the inner cell body and try get a few Chloroplasts, easly from the fungal forms if their reliant on the light, or any other proto-plant life.
I suggest you look up other Organells in google or such.
it will be usefull.
Suggestion for future reference: Octo-Helix DNA
Why? with the current double-helix only allows for a certain number of Amino acids, by increasing the strands from 2 upwards to 3 you vastly increase the data storage in the strands that relate to the number of Amino acids, and because proteins are made from hundreds of amino acids, the number and uses/power of the proteins you can create. Also has the added side effect of making you essentialy virus proof on things that work on 2 strands. the downside is that if you go from 2 strands to 3 strands then anything you pick up DNA wise will decrease in value, its alot more reasource intensive.
Octo-Helix DNA is the Tyranid strand of DNA in warhammer 40k ^^
Just to note: i forgot wich way round the chlorophyl and chloroplats are, so, take that with a grain of salt.
