We think that the larger the organism, the more cells it will have. We will use three plants: coleus, pine-stem, buttercup; and two animals: pig, human cheek cells.

Organism

Description

Average Size

Coleus (medium)

Hairy, cactus shape @ 4x; Purple dots in the middle of blue walls (outlines) @ 10x; scales of a fish @ 40x

~38 microns

Pine-stem (big)

Multiple circle within a circular figure, multi-colored @ 4x; resembles an eye instead of brown eyes with black pupils, we have green eyes with pink pupils @10x; looks like a rainbow fish @ 40x

~ 20 microns

Buttercup (small)

Circular outer wall, inside filled with green space and a star-shaped figure in the middle @ 4x; more spacious than the other previous organism, the star is surrounded by a bunch of green spots @ 10x; more space between each cell

~109 microns

Pig (medium)

Shaped like an embryo with orange as the outside layer, and pink within @ 4x; @10x, we see the cells are much bigger and resembles a zebra but instead of black and white stripes, we see pink and white random stripes; @40x we could see the spaces between each cells

~46.6 microns

Human cheek cells (medium)

@4x small black circles with holes in them, resembling a black ring; @10x the cells are very spaced out and vary in shape and size, resembles blue crystals with black lines through it; @40x completely blue

~60 microns

Our initial hypothesis predicted that the bigger the organism, the more cells the organism will have. We proved this correctly because a small plant like a buttercup has very big cells, while a large organism like a pine has billions and billions of small cells.
