6. Vasculature of a mouse placenta

7. Rotifers are tiny multicellular organisms found commonly
in freshwater environments around the world.

8. Fibroblasts are cells that help maintain
tissue structure by secreting proteins
like collagen and elastin.

9. Vascular smooth muscle cells

10. Gastropods like this marine snail use their radula, a
rake-like feeding organ, to scrape food from surfaces.

11. Pyramidal neurons and their dendrites from a mouse brain.

12. Developing muscles in a limb from a mouse embryo.

13. Human Immunodeficiency Virus

14. Peripheral nerves of a mouse embryo

15. Leaf cells from a genetically engineered tobacco
plant made to produce fluorescent proteins.

16. Fluorescently glowing rat hearts

17. Adhesive pad of a ladybug

20. Appendage of an amphipod

21. High-magnification cross section of an aloe plant.

22. The Arabidopsis thaliana plant was the first plant to have its entire genome
sequenced and is commonly used to study basic plant biology.

23. Plankton are, by definition, aquatic organisms that cannot swim against a current.

24. By supplying oxygen and nutrients, blood vessels are
necessary for a healthy and functional retina.

25. Ferns first appeared some 360 million years ago.

26. The brain of a Drosophila larva (fruit fly), with pre-mature eye
structures (spotted red structures in the top right and left).

27. High-magnification view of an antenna from a moth.

28. The midbrain vasculature of a zebrafish larva.

29. Blood vessels in the brain of a live zebrafish embryo.

30. Just before the fruit fly Drosophila enters metamorphosis to become an adult fly, the
developing eye begins to form a furrow where specialized light-sensitive cells will develop.

31. Daphnia, commonly known as the water flea, are mostly transparent plankton less than 5 mm
in length. One can be seen here playing with a colony of Volvox, a type of green algae.

32. Hair follicles, shown here from the skin of a mouse, are the site of new hair growth.

33. The intestinal mucosa of a 7.5 day-old chick embryo.

34. Filaments from the green algae Spirogyra, so named for
the spiral arrangement of chloroplasts within each cell.

35. A mouse embryo at 40-times magnification 13.5 days after fertilisation.

36. A cut across the central vein of a leaf from Acrostichum
aureum, a mangrove fern, at 20-times magnification.

37. A transverse section of a stem from Arabidopsis at 200-times magnification.

38. A 40-times magnified view of the trachea from a silkworm.

39. A section from the mouse cerebellum

40. A sagittal cut and view of the rat cerebellum.

41. A 400-times magnified view of diatoms.

42. The hippocampus of a mouse

48. A fluorescence and differential interference
contrast image of a tick feeding on its cattle host.

49. Actinoptychus heliopelta, a marine centric diatom.

50. Diatoms from the Pleurosigma genus

51. Scales from the wing of a sunset moth.

52. Micrasterias, unicellular green algae from the
order Desmidiales, undergoing mitosis.

53. Mitotic spindles (red) pulling chromosomes (blue) in a
dividing Xenopus (clawed frog) egg in vitro.

54. A view of Xenopus tadpoles with confocal microscopy.

55. A developing wing of a butterfly

56. A confocal image showing the aerial root of an orchid, Phalaenopsis sp.

57. A cross-section of a mouse small intestine.

58. Light-perceiving cells called photoreceptors

59. Ebola virus

60. Plant meristem

61. Gecko feet

62. Desmids are single-cell algae
found mostly in freshwater
environments.
