Across 3. Contains Smooth and Rough ER 8. Structure for DNA storage and coordination of cell activity 11. Mixture of water, minerals, and proteins that surround a cell and provide structural support 12. Regulates what enters and exits cell via pores; continuous with Rough ER 15. Membrane-bound sacs of digestive enzymes used to deconstruct macromolecules for recycling in the cytosol 16. Associates with ribosomes; completes process of Ribosomes by receiving protein, confirming it, and package it for transport to Golgi Apparatus 17. refers to the way that organelles in Eukaryotic cells live and function in isolation, away from other organelles, within cells. Important because it allows for efficiency. The organelles get to have their own perfect environments allowing for an optimal work environment. 18. 1µm-10µm size; No membrane-bound organelles; possesses a single circular chromosome and non-membrane-bound ribosomes

Down 1. Recipient of proteins from transport vesicles > sorts and sends proteins to destination within cell 2. MORE surface area; LESS volume is the most efficient because cells get resources through the plasma membrane. Cell size is limited due to the ratio becoming less favorable as cell size increases. 3. The process of a unicellular organism becoming a cell host by engulfing other smaller cells. 4. The theory that organelles within eukaryotic cells originated as individual prokaryotes that were engulfed by an ancestral eukaryotic cell. This ancestral eukaryote eventually evolved into a single cell organism. 5. 10µm-100µm size; has membrane-bound organelles; possesses multiple linear chromosomes and both bound and unbound ribosomes 6. Site of photosynthesis 7. Synthesizes lipids, metabolizes carbs, detoxifies drugs/poison, stores calcium 9. Site of cellular respiration 10. Membrane-bound sac of cytoplasm that stores and disposes of nutrients and proteins 13. “Protein Factories”; Site of protein synthesis; consists of small and large subunits 14. Thick solution of water, protein, and lipids; provides cell structure and aids in metabolic activity
