Cells

5. States that early eukaryotic cells were formed when a cell engulfed another, taking on a new job inside the cell
6. The genetic material of the cell, responsible for the development and function of an organism
9. An organelle present in eukaryotic cells that contains DNA and is surrounded by its own double membrane.
11. The difference in concentration of a material between either side of the cell membrane
12. The fluid inside a cell that surrounds the cell’s organelles.
14. The movement of cell materials into or out of the cell AGAINST the concentration gradient. Requires energy.
15. A semi-permeable phospholipid bilayer that surrounds ALL cells membrane

1. An organism made up of more than one cell
2. The general movement of substances across the cell membrane either into or out of the cell
3. structures that are surrounded by their own double membrane.
4. An organism made up of cells that do NOT have a nucleus or specialized organelles
7. An organism made up of only one cell.
8. An organism made up of cells that DO have a nucleus and specialized organelles
10. The passive transport of materials across the cell membrane. Materials move directly across the cell membrane
13. The movement of cell materials into or out of the cell DOWN the concentration gradient. Does not use energy.
