CELLS

2. is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
3. is the specialized DNA sequence of a chromosome that links a pair of sister chromatids.
10. are a type of leucoplast that is specialized for the storage of lipids in plants.
14. are tiny, numerous organelles that are bounded by 2 membrane
15. is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
18. any of a class of substances which occur as constituents of the cell walls of plants
19. are the food producers of the cell.
20. invloved in the architecture of cells and internal movement.
23. found in zones of the plant where growth can take place.
24. Within the __________, proteins are stored, modified, sorted, and packed into vesicles (which are then closed off as Golgi vesicles) for further transport.
27. a narrow thread of cytoplasm that passes through the cell walls of adjacent plant cells and allows communication between them.
28. is the phase of the cell cycle in which a typical cell spends most of its life.
29. contended that every cell comes from a preexisting cell

1. discovered in 1955 by George E. Palade nd described them as small particles in the cytoplasm.
4. organisms whose cells have a nucleus enclosed within membranes
5. the material or protoplasm within a living cell, excluding the nucleus.
6. one cell divides once to form two identical cells.
7. a substance formed in or necessary for metabolism.
8. is a naturally occurring substance (a polysaccharide) found in berries, apples and other fruit.
9. component of the cytoplasm of a cell, within which various organelles and particles are suspended.
11. a carbohydrate whose molecules consist of a number of sugar molecules bonded together.
12. dense region composed of protein complex, located in the outer region face of each centromere
13. a colorless organelle found in plant cells, used for the storage of starch or oil.
16. a narrow thread of cytoplasm that passes through the cell walls of adjacent plant cells and allows communication between them.
17. are specialized peroxisomes found in plants and also in filamentous fungi
21. are the pigments that give red, purple, and blue plants their rich coloring.
22. any of a number of organized or specialized structures within a living cell.
25. tiny, keg-shaped structures
26. concluded that all living tissue is composed of cells
