All of the following are found in both plant and animal cells except..
a) cell membrane
b) mitochondria
c) cell wall
d) golgi bodies

The best answer is C.

The outermost covering of plant cells is called the cell wall.  It is made up cellulose, is rigid  and can be seen under a light microscope. It is absent in animal cells.

The outermost covering in animal cells is the cell membrane. It is made up of lipids, proteins, and small amounts of carbohydrates. It is a thin and delicate structure that can only be seen under an electron microscope.

Plant cells  have  both cell wall and cell membrane 

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

not sure if this what   you'r looking for would be percent composition
