Animal Cell

9. A cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; Consists of rRNA and protein molecules
10. A dense region of DNA in a prokaryotic cells.
11. One of a family of closely related plant organelles, including chloroplasts, chloroplasts, and amyloplasts
12. An organelle in eukaryotic cells that serves as the site of cellular respiration.
13. A threadlike, gene-carrying structure found in the nucleus.
16. A network of microtubules, microfilaments, and intermediate filaments that branch throughout the cytoplasm and serve a variety of mechanical and transport functions.
17. A protective layer external to the plasma membrane in plant cells.
18. An organelle found only in plants and photosynthetic protists that absorbs sunlight of organic compounds from carbon dioxide and water.
19. An organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum.
20. The membrane at the boundary of every animal cell and acts as a selective barrier.

1. A hollow rod of tubulin protein in the cytoplasm of all eukaryotic cells and in cilia, flagella, and the cytoskeleton
2. A membranous sac in a mature plant cell with diverse roles in reproduction, growth, and development.
3. An extensive membrane network in eukaryotic cells, composed of ribosome-studded (rough) and ribosome-free (smooth) regions.
4. The entire contents of the cell, exclusive of the nucleus, and bounded by the plasma membrane.
5. A sac made of membrane inside of cells
6. The complex of DNA and proteins that make up eukaryotic chromosome.
7. A membranous sac formed by phagocytosis.
8. A solid rod of actin protein in the cytoplasm of almost all eukaryotic cells.
14. A specialized structure in the nucleus, formed from various chromosomes and active in the synthesis of ribosomes.
15. The chromosome-containing organelle of a eukaryotic cell.
