Across4. A large organelle with a double membrane found in plant cells. Contain their own DNA. Involved in the synthesis and storage of different chemical compounds. Examples are chloroplasts and leucoplasts (7)
5. An external structure that surrounds the cell membrane for structural support and protection. Composed of cellulose (in plants) or peptidoglycan (in bacteria). (4,4)
6. A small cylindrical organelle consisting of a group of microtubules, and occurring as a pair in the centrosome in the cells of animals and some other organisms. (9)
10. Layers of intracellular membranes associated with ribosomes and is involved in protein synthesis. (5,11,9)
11. An organelle composed of a stack of cisternae in which proteins are assembled and then packaged in vesicles for exocytosis. (5,9)
12. An organelle that contains genetic information. (7)

Down1. A continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells. It is not associated with ribosomes and is involved in the synthesis of lipids. (6,11,9)
2. An organism with cells that do not have a membrane surrounding the nucleus and lack most organelles. Bacteria and Archaea. (10)
3. An organelle involved in storage in plant cells. (7)
7. A bilayer (double layer) of phospholipids that encloses the contents of a cell and controls the movement of substances into and out of the cell. (4,8)
8. The fluid cytosol of a cell, together with the organelles that it surrounds. (9)
9. The structure in prokaryotes that contains genetic material. (8)
13. A fragment of DNA that is outside the chromosomes, in the cytoplasm. Usually include genes and can replicate independently. (7)
15. An organism whose cells contain a membrane-bound nucleus and other membrane-bound organelles. Protists, fungi, plants, and animals. (9)
