About This Presentation

Slide 1 - Cell Division in the Onion Root Tip RS: Ms. Alvarez CT: Mrs. Rojas Adapted from M. Arias
Slide 2 - Cell Division in the Onion Root Tip RS: Ms. Alvarez CT: Mrs. Rojas Adapted from M. Arias The Cell Cycle Cells grow and divide. As one cell enters Mitosis, two cells exit which are exact replicas or clones of the original “parent” cell. Cells that no longer need to divide exit the cell cycle in G1(ex. neurons, muscle cells, fat cells do this). Purpose: to replenish dead or dying cells, to allow an organism to grow and develop
Slide 3 - Cell Division in the Onion Root Tip RS: Ms. Alvarez CT: Mrs. Rojas Adapted from M. Arias The Cell Cycle Cells grow and divide. As one cell enters Mitosis, two cells exit which are exact replicas or clones of the original “parent” cell. Cells that no longer need to divide exit the cell cycle in G1(ex. neurons, muscle cells, fat cells do this). Purpose: to replenish dead or dying cells, to allow an organism to grow and develop Interphase A cell spends the majority of its lifetime in interphase. Cell grows and carries out normal cell processes DNA replicates Prepares for cell division Onion root tip Plant cell

Cell grows and carries out normal cell processes DNA replicates Prepares for cell division Onion root tip Plant cell 4 Stages of Mitosis: Plants & Animal Cells Prophase: Chromosomes condense and form visible bodies. Nuclear envelope breaks down. Onion root tip whitefish Metaphase: Chromosomes line up in the middle of the cell. Spindle fibers attach to the centromeres. Anaphase: Centromeres split. Sister chromatids separate and are pulled to opposite sides of the cell. Telophase: Nuclear envelope reappears. Cytokinesis The cytoplasm and all its contents divide

Add a very small drop of 1M HCL acid to the root tip on the slide and let it sit for 4 min. Using a paper towel soak the HCL away from the root tip. Cover the root tip with a drop staining solution and let stand for 2 minutes.

Add one drop of water and gently lay a coverslip over the root tip. Using a pencil eraser, carefully apply pressure to the coverslip area to squash and spread the root tip tissue. Use the low power objective on your microscope to look for thin layers of cells and then use the 40X power objective to observe mitotic stages in individual cells. Identify chromosomes at the various stages of mitosis in the water treated root tips. Make sketches of the stages observed.
