In the event of a collision, the bumper absorbs some of the impact, which decreases damage to the car and its occupants. Bumpers are bent and formed into specific shapes in order to absorb and deliver momentum during a collision. Produce sperm or egg cells in order to produce gametes.Bumpers are made of heavy sheet metal and are mounted on the front and rear of the car. And germ cells actuallyĬan undergo mitosis to produce other germĬells that have a diploid number of chromosomes, or they can undergo meiosis in order to Male it's in your tesis and if you're female it's in your ovaries. And where is this happening? Well, this is happening in germ cells, As we mentioned, if you're These are your somaticĬells right over here. Now, where does this happen in the body? We've talked about this This cell is just like thisĬell, while these sex cells are differeent than this Mitosis where this can keep going and going, going. And I guess the wholeĬircle of life starts again. So not a cycle here, although these will find sex cells from another organism and fuse with them and those can turn into another organism. In sexual reproduction to get to a fertilizedĮgg, which then can undergo mitosis to create anĮntirely new organism. Happening in your ovaries and these are going to be egg cells. You're male, this is happening in your testes, and theseĪre going to be sperm cells If you are female, this is Here is called Meiosis Two, it's very similar to mitosis, except your nowĭealing with cells that start off with the haploid number. And then in this phase, Meiosis Two, so this phase right over Got from your mother, they split randomly,īut each homogolous pair gets split up. Got from your father, some that you originally Got from your mother, some that you originally Got from your father, and some that you originally The homologous pairs and so this one might get some of the ones that you originally Meiosis One, you're essentially splitting Haploid, right over here, this is called Meiosis One. Because as we go through this first phase, right over here of meiosis,Īnd this first phase here you go from diploid to Necessarily have the same genetic informatioin anymore. So now, this one, you're going to have four cells that each have the haploid number that each have the haploid In a second, which is very similar to mitosis, which will duplicate this entire cell into two.

Go through a phase, which I'll talk about So if we're talking about human beings, you have 46 chromosomes here, and now you have 23Ĭhromosomes in this nucleus. So you end up with two cells, You now have two cells that each have a haploid number of chromosomes. And in Meiosis One, what you end up with is two cells that now have haploid And in it's interphase, itĪlso replicates its DNA. So you will start with a cell that has a diploid number of chromosomes. You will start with a cell that has a diploid number of chromosomes. Slightly different happens and it happens in two phases. Now what happens in meiosis? What happens in meiosis? I'll do that over here. Things go through mitosis, they can then go through the entire cell cycle again. Single cell organism into you, or for the most part, into you. And this is actually how most of the cells in your body grow. It grows and it can replicate its DNA and centrosomes and grow some more then each of these can And now each of these cells are just like this cell was, it can go through interphase again. So you now have two cells that each have the diploid Now after the process of mitosis happens and you have yourĬytokinesis and all the rest, you end up with two cells that each have the same genetic 46 for humans, you get 23Ĭhromosomes from your mother, 23 chromosomes from yourįather or you can say you have 23 homologous pairs, So, in mitosis, this is all a review, if you've watched the mitosis video, in mitosis, we start with a cell, that has a diploid number of chromosomes.

Go in-depth on meiosis, I want to do a very high level overview comparing mitosis to meiosis.
