In this unit for science we learned about sexual and asexual reproduction, mitosis, meiosis and many more interesting things on cells and how they work.
In class when we learned about asexual and sexual reproduction, we learned the many differences between the two. For example asexual reproduction is when there is a genetic of its parent, and there are many types of asexual reproduction like binary fission, budding, fragmentation and more. But sexual reproduction is where a male gamete must fertilise a female gamete and the organism is not an exact copy of the parent because it is a mix of both parents and none of the organisms look the same, they are all different.
When we learned about mitosis we used materials like string, beads and pipe cleaners to help us understand all the different stages of mitosis and we remembered the order by remembering PMAT which stands for prophase, metaphase, anaphase and telophase. Prophase is when the nucleolus disappears and spindle fibres form and attach to the centrometres of the chromosomes. During metaphase the spindle fibres bring the chromosomes to the middle of the cell on the equator. Anaphase is when the spindle fibres pull the sister chromatids to opposite poles of the cell. And in the final stage telophase the spindle fibres disappear and a nuclear membrane appears around each set of chromosomes.
When we learned meiosis we did the same thing as we did when we learned mitosis, using materials to help us learn about meiosis. Meiosis is when there is sexual reproduction and it has more stages than mitosis, there are two.
