Answer 2

Hi there :)
A is the rough endoplasmic reticulum. It is called rough because it is covered with ribosomes, which make proteins for secretion out of the cell or transport into other organells.
B seems to be the cytoplasma. This is the gelly-like filling of the cell, where all of the organelles, many enzymes and the cytoscelletton are located.
G should be the smooth endoplasmic reticulum. Fatty components for example as building blocks for membranes are made there.
D is probably the nucleolus, it is not an organelle, bacause it's not separated by a membrane. It is more like a part from the nucleus where the ribosomal RNA(rRNA, which makes the ribosomes) is transcribed.
E is the nucleus itself. Here lies all the DNA, genetic information, that defines an organism.
F is a mitochondrium. It is an organelle inolved in the cellular respiration. Here the biggest amount of ATP is generated.
C is the Golgi Apparatus. It modifies, packages and labels proteins for secretion out of the cell or into other cell compartments.
H is a ribosome. This is an RNA-protein complex that carries out the translation(protein biosynthesis). The RNA plays the main part in this process, the protein have an importance for the structure.
P.P. Sorry that I mixed C and G..
