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