science

1. - a short hairlike extension of a cell used either for movement or as a sensory organelle.
3. - a nonpigmented cellular organelle found plant cells whose functions include storing starches, lipids, and proteins.
5. - the cellular organelle that directs the protein-building process.
7. - a cellular organelle that functions in the organization of microtubules.
8. - one of the fundamental models of biology that states that cells are the smallest form of life, come from preexisting cells, are the basic building blocks of all life forms and carry out life processes to maintain homeostasis.
9. - the diffusion of water molecules through a semipermeable membrane.
11. - a stack disk - shaped thylakoids within a chloroplast
12. - the movement of substances across a cell membrane from regions of low concentration to regions of high concentration by any means that requires the use of energy.

1. - an organelle found in plant cells that hold materials and helps maintain the cell’s shape through turgor pressure.
2. - the internal balance within the systems of living organisms that must be kept stable in order to maintain life.
4. - a cellular organelle that contains digestive enzymes.
6. - a rigid structure made by cells of plants, fungi, and most bacteria to surround the cell membrane
7. - the genetic material of eukaryotic cells consisting of DNA and associated proteins.
8. - a group of individual organisms of the same species living closely together.
10. - the cellular organelle in which aerobic respiration takes place to produce energy from food.
