Good EM Drawings Show Structure and Annotate Function

Nucleus

Seen in EM: spherical or oval, with a double membrane pierced by pores.
Annotation: holds the chromosomes and controls cell activities.

Chromosomes

Seen in EM: dense, darkly staining regions inside the nucleus when condensed.
Annotation: carry the genetic information as DNA.

Mitochondria

Seen in EM: oval, with a double membrane whose inner layer folds into cristae.
Annotation: site of aerobic respiration, where ATP is made.

Chloroplasts (plants only)

Seen in EM: oval, with a double membrane, stacks of thylakoids (grana) and surrounding stroma.
Annotation: the thylakoid membranes and stroma are the sites of photosynthesis.
