19 Questions

1. Cells containing membrane enclosed compartments. Typically 10-30 micrometers.

2. A distinct structure or compartment within a eukaryotic cell that performs specific tasks.

3. In plants only - a membrane enclosed region that serves as a toxic waste dump. The deterioration of these hastens the death of the cell and the plant.

4. One of the three broad categories into which all organisms are grouped. Eukarya - Archaea - and Bacteria.

5. Scientist who successfully disproved spontaneous generation.

6. Organelle responsible for the synthesis of RNA into Proteins.

7. Unique to eukaryotic cells; anchors the organelles in place in the cell - includes three types of fibers Microfilaments - microtubules and intermediate filaments.

8. Discovered that plant tissues are made of cells.

9. Membrane enclosed sacs containing digestive enzymes that break down proteins - carbohydrates - and fats.

10. Discovered that animal tissues are made of cells.

11. Cells that do not contain membrane enclosed compartments. Single celled organsms roughly one micrometer long. Attached Flagellum gives the organism mobility.

12. Challenged the notion of spontaneous generation by postulating that cells come from pre-existing cells.

13. In plant cells only - this supports the cell shape and protects the cell.

14. The main sites of energy transformation in eukaryotic animal cells.

15. This type of cell is made up of dendrites and axons.

16. The simplest unit of biological organization. Term coined by Robert Hooke who invented the first microscope. Basic unit of life.

17. In plant cells only - this organelle is responsible for photosynthesis

18. The barrier between cells made of a bilayer or phospholipid molecules.

19. Organelle that sorts and modifies proteins from ER and prepares them for transport to specific parts of the cell.
