I can place in order pictures that show chromosome movement during cell division. I can classify methods of reproduction as sexual or asexual.
How do little elephants grow up to be BIG elephants?
Single parent produces offspring that are identical to the parent Organisms with eukaryotic cells reproduce by mitosis and cell division
1. Growth 2. Repair 3. Replacement
Budding – using mitosis and cell division to form a bud which will become a new organism Regeneration – using mitosis and cell division to regrow body parts
Cell division occurs in a series of stages, or phases.
Cell Cycle Interphase Prophase Metaphase Anaphase Telophase & Cytokinesis
Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils ( chromatin ) at the start, but each chromosome and its copy( sister chromosome) change to sister chromatids at end of this phase CELL MEMBRANE Nucleus Cytoplasm
Animal Cell Plant Cell Photographs from:
Mitosis begins (cell begins to divide) Centrioles (or poles) appear and begin to move to opposite end of the cell. Spindle fibers form between the poles. Centrioles Sister chromatids Spindle fibers
Animal Cell Plant Cell Photographs from: Spindle fibers Centrioles
Chromatids (or pairs of chromosomes) attach to the spindle fibers. Line up along the center of the cell Centrioles Spindle fibers
Animal Cell Plant Cell Photographs from:
Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers
Animal Cell Plant Cell Photographs from:
Two new nuclei form. Chromosomes appear as chromatin (threads rather than rods). Mitosis ends. Nuclei Chromatin
Animal Cell Plant Cell Photographs from:
Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes. Same # as original Plants form a cell plate to divide cytoplasm
