Across
  1. 2. modify, sort, & package molecules from ER for storage or transport out of cell
  2. 4. creates ATP, has its own DNA, site of cellular respiration
  3. 6. contains pores for materials to enter & leave the nucleus
  4. 8. all organisms are composed of cells, the cell is the basic unit of structure, all cells come from prexisting cells
  5. 11. an organism with many cells
  6. 14. lacks ribosomes on its surface, makes cell products that are used inside the cell like special lipids called steroids
  7. 15. is the nucleus, makes mRNA
  8. 16. stores water, food, and waste
  9. 18. an organism with only one cell
Down
  1. 1. contain digestive enzymes
  2. 3. only found in plant cells, uses energy from sunlight to make glucose in a process called photosynthesis, contains its own DNA
  3. 5. an organelle in plant cells that supports and protects the cell
  4. 7. controls the activities in the cell, contains DNA in the form of chromatin
  5. 8. function in moving cells, fluids, or in small particles across the cell surface, shorter and more numerous on cells
  6. 9. has ribosomes on its surface, makes membrane proteins, and helps export these proteins out of the cell
  7. 10. function in moving cells, fluids, or in small particles across the cell surface, longer and fewer (usually 1-3) on cells
  8. 11. a membrane around the cell that controls what enters and what leaves the cell
  9. 12. an organelle that provides a medium for chemical reactions to take place
  10. 13. join amino acids to make proteins, made of special proteins and rRNA
  11. 17. appear during cell division and help pull chromosome pairs apart to opposite sides
  12. 19. an organelle that makes up the cytoplasm, helps the cell maintain shape and helps organelles move around
