Centrioles Sites for active RNA synthesis.
Lysosomes Optimally active at a pH of about 8.5.
Thylakoids Flattened membranous sacs forming the grana of chloroplasts.
Ribosomes Those on chloroplasts are larger (80S) while those in the cytoplasm are smaller (70S).
The ribosomes of a polysome translate the mRNA into protein.
Mitochondria divide by fragmentation.
All cell arise from pre-existing cells.
The lipid component of the membrane mainly consists of phosphoglycerides.
Glycocalyx May be capsule or slime layer
