Meiosis is the process by which the nucleus divides in all sexually reproducing organisms during the production of spores or gametes. This Meiosis concept map depicts the subject from a bird's eye perspective. The central concept was highlighted in green, while the other elements were highlighted in grey. It can be difficult for beginners to understand how each node is connected. As a result, you can use colors to classify elements and make them more understandable. EdrawMind is the perfect tool to draw the Meiosis concept map as it allows you to instantly create topics and subtopics, which can easily be connected.

A centrosome is an organelle near the nucleus of a cell that contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division.
