Lab Unit 1

This is a chocolate diagram of DNA replicating

This is the chocolate model of tRNA

This is a model of a working cell made from a cake and chocolate. Besides the cake and colored frosting, each part of the cell is created with different chocolate in different colors. I wasn’t able to fit all parts of it into the cake, but what is included in the cake is its cell membrane, Endoplasmic reticulum, both rough and smooth ER, a nucleus, nucleolus, mitochondrion, Golgi apparatus, vesicles, lysosomes.
The cell membrane is the layer surrounding the cytoplasm and regulates what enters and exits the cell.
Endoplasmic reticulum is a system of saccules and channels in the cytoplasm.
The Nucleus is an organelle that has chromosomes and controls the structure and function of the cell.
The nucleolus produces ribosomal subunits.
Mitochondrion is membrane bound organelle in which ATP molecules are produced during the process of cellular respiration.
Golgi apparatus is also an organelle with saccules and vesicles that process, package and distribute molecules for the cell.
Vesicles are small membrane bound sacs that are substances with in the cell.
Lysosomes are vesicles that contain hydrolytic enzymes for digesting macromolecules.


It got a little mixed up, this is the second picture. I had finished some of the chocolates, only the cell membrane frosting was done. :)


Here is the start of the cell. A pretty simple little cake! :)





















The finished product!




I did find this to be slightly difficult, but I love baking and was happy to play around with making the various parts out of chocolate. Unforutnately no one can enjoy eating it because I was sick when I made it.
