Match the following: a. tiny structures which synthesize proteinsb. round structure within the cellc. contain genes with the information controlling celld. produce and package cell secretionse. channel through which molecules move in cytoplasmf. produce the spindle fibers for cell divisiong. produce r-rna to make ribosomes1. centrioles2. nucleolus3. nucleus4. endoplasmic reticulum5. golgi bodies6. ribosomes7. chromosomes

1. Centrioles can be correctly matched with F, that is, produce the spindle fibers for cell division.

2. Nucleolus can be correctly matched with G, that is, produce r-RNA to make ribosomes.

3. Nucleus can be correctly matched with B, that is, round structure within the cell.

4. Endoplasmic reticulum can be correctly matched with E, that is, channel through which molecules move in cytoplasm.

5. Golgi bodies can be correctly matched with D, that is, produce and package cell secretions.

6. Ribosomes can be correctly matched with A, that is, tiny structures which synthesize proteins.

7. Chromosomes can be correctly matched with C, that is, contain genes with the information controlling cell.

the answer is:

carbon dioxide
