Biology

1. The clear, yellowish, fluid part of the blood that carries the blood cells.
2. Diffusion diffusion of solutes through transport proteins in the plasma membrane.
9. biological structure that performs a distinctive function inside a cell
10. (a type of white blood cell) surrounds and destroys foreign substances
12. containing a lower amount of solute in comparison to the solute concentration in other solutions
13. the movement of ions or molecules across a cell membrane into a region of higher concentration
14. transport and fusion of secretory vesicles with the plasma membrane and the extracellular space.
15. within all living things
17. the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
18. single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
19. process by which cells take in substances from outside of the cell by engulfing them in a vesicle.

1. an active, energy consuming process where extracellular fluid and solutes are taken up into a cell via small vesicles.
3. the intermingling of substances by the natural movement of their particles.
4. All animals, plants, fungi,
5. all forces acting on the body are balanced with an equal and opposite force
6. the theory that all living things are pre existing
7. capable of being permeated. especially : having pores or openings that permit liquids or gases to pass through.
8. external solution that has the same solute concentration and water concentration compared to body fluids.
11. a thin polar membrane made of two layers of lipid molecules.
12. Having a greater degree of tone, tension or tonicity.
16. net movement of water across a semipermeable membrane.
