a) Screenshot from the animation where the image shows the cell membrane, i.e. a double layer of fat molecules with membrane proteins (NTA Skolutveckling, 2021). b) Screenshot from the animation where the image at the top left shows how the nutrient molecules are transported through the cell membranes in the intestinal cell and the capillaries and into the blood capillary (the image at the bottom right). The background image is intended to give an overview of one enlarged microvilli (NTA Skolutveckling, 2021).

Analytical tool for identification of everyday and scientific terms based on organizational levels.
| TYPE OF TERM | MESO | SUBMICRO |
|---|---|---|
| 10–6 – 10–8 m | 10–8 – 10–10 m | |
| Scientific term | Microvilli | Nutrient molecules |
| Corresponding everyday expression | Fluff on fluff/protrusion on protrusion | Building blocks |
| Scientific term | Membrane proteins | Phospholipid molecule |
| Corresponding everyday expression | Gate/Channel/Entry/Door/Transport thing | Cotton swabs |
