all eukaryotic cells have mitochondria but only plants and some photosynthesis process of chloroplast? what can be inferred?
kumpel [21]
You may know that your body is made up of cells (trillions and trillions of them). You may also know that the reason you need to eat food—such as veggies—is so that you have the energy to do things like play sports, study, walk, and even breathe.But what exactly happens in your body to turn the food energy stored in broccoli into a form that your body can use? And how does energy end up stored in the broccoli to begin with, anyway?The answers to these questions have a lot to do with two important organelles: mitochondria and chloroplasts.

Why did you cut out the chromosomes in pairs
Debora [2.8K]
Well, I don't fully understand your question. I think I know what you're getting at though.

In a system of sexual reproduction, you have genes coming from both an egg and the sperm. Therefore, it'll only contain half the total amount of chromosomes (46 in humans). A sperm will have 23, and the egg will have the other 23. Is that what you meant why the chromosomes are cut out in pairs? If that wasn't your question, please elaborate and I'll return to answer it to the best of my capabilities.
