WebNov 1, 2003 · The first mitotic division induces furrowing at the spindle midzone, but no cleavages are observed at positions distant from the spindle. The second mitotic divisions induce furrowing at the two spindle midzones, but, in addition, furrowing appears between the two spindle poles in the absence of metaphase chromosomes or anaphase movements.

Attach drawings of all 5 stages of mitosis (interphase, prophase, metaphase, anaphase, telophase/cytokinesis) from both the whitefish blastula and the onion root tip. Images should be hand-drawn. You should not use the images found in your exercise. 2. WebOne difference between cell division in plants and animals is that plant cells form a cell wall after mitosis to separate the nuclei and cytoplasm of the two new identical cells. After animal cells undergo mitosis, the cell membrane pinches together along along a cleavage furrow during cytokinesis.
