These illustrations can be printed or imported into a digital note-taking app.

Comparative illustration of a prokaryotic and an eukaryotic cell. Basic cell organelles and components are labelled.

Illustration of a cell's nucleus, highlighting the nuclear pores, nuclear envelope, nucleolus and chromatin. On the right, an illustration of DNA, chromatin and a chromosome is shown.

Illustration of a cell's mitochondrion, highlighting the intermembrane space, inner and outer membranes, cristae, matrix and free ribosomes.

Illustration of a cell's chloroplast, highlighting main features like the thylakoids and its lumen, stroma, DNA, inner and outer membranes and intermembrane space.

Illustration of a cell's plasma membrane, highlighting the hydrophobic and hydrophilic regions as well as key proteins and lipids within the membrane. On the right, an illustration of a phospholipid highlighting the hydrophilic head and hydrophobic tail are shown.

Illustration of a phospholipid, highlighting the chemical structure of the polar head and nonpolar tails

Labelled illustration of the brain (lateral or side view), highlighting the four lobes, the cerebellum, pons and medulla oblongata

Labelled illustration of the human skull (lateral or side view), highlighting the main bones including the frontal, parietal, sphenoid, occipital, mandible, maxilla, nasal, lacrimal, zygomatic and ethmoid as well as some markings like the mental foramen and external acoustic meatus

Illustration of a neuron or never cell, highlighting the dendrites, cell body and axon.

Illustration of an anatomical heart, highlighting main vessels like the aorta and vena cava and the four heart chambers and their corresponding valves.

Illustration of crossing over between homologous chromosomes (one in pink and one in blue). The first step shows the homologous chromosomes aligning. The second step shows the chromosomes close together, indicating crossover. The last step shows the product of crossing over: the two chromosomes now have a recombinant chromatid and a non-recombinant chromatid.
