In animal cells, the spindle moves during cell division. The cells divide where it comes to rest. ... Under the microscope the researchers observed mitosis in moss plants without the TPX2 genes.

Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the ...

Plant cells do not have centrioles and their mitosis is frequently likened to the chromosome-based mechanism seen in acentriolar animal cells. However, this is a false analogy. Although plants can ...

During mitosis, many of the spindle fibers attach to chromosomes at their kinetochores (Figure 6), which are specialized structures in the most constricted regions of the chromosomes.

In animal cells, the centrosomes, which contain centrioles, migrate to opposite poles of the cell, forming the spindle poles.

Mitosis: Meiosis: Prometaphase The centrioles are now at opposite ends of the cell. The spindle fibers from both of the centrioles attach to each one of the chromosomes.

Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae. Until now, little was known about ...
