Across
- 2. a jelly-like substance that contains dissolved molecular building blocks such as proteins, nucleic acids, minerals, and ions
- 7. contains enzymes; they defend a cell from invading bacteria and viruses, and break down damaged or worn out cell parts (animal cells only)
- 8. controls most functions of an eukaryotic cell and it is surrounded by an envelope that allows certain things in and out
- 9. Tiny organelles that link amino acids together to form proteins
- 11. sacs used for the storage of water, food molecules, and ions
- 13. Carries out photosynthesis; coverts solar energy into energy-rich molecules that the cell wall can use (only in plant cells)
- 14. Structures specialized to perform distinct processes within a cell
- 16. a rigid layer that gives protection, support, and shape to the plant cell (only for plant cells)
Down
- 1. assists in cell division, provides strength to the cell, helps in cell movement, and gives the cell its shape
- 3. site for synthesis, storage and transport of melanin (animal cells only)
- 4. small region of cytoplasm that produces microtubules and helps with animal cell division (centriole is animal cells only)
- 5. takes up most of the space inside a plant cell, it is filled with watery fluid that strengthens and supports the entire plant; it has waste product and pigment that give color to the plant cell (only for plant cells)
- 6. layered stacks of membrane-enclosed spaces that process, sort, and deliver proteins
- 10. supplies energy to the cell by converting food molecules into usable energy
- 12. forms a boundary between a cell and the outside environment and controls the passage of materials into and out of a cell
- 15. makes lipids, breaks down drugs and alcohol; can have ribosomes or no ribosomes
