Which are structures in eukaryotic cells?
Select all that apply.
mitochondria
DNA
nucleus
plasmid
Eukaryotic cells do contain mitochondria, DNA, and plasmid, but lacks a nucleus. Therefore, all the options but 'nucleus' are correct.
It's actually everything but plasmid
HELP MEEEE ....please
AJ+L thats prokaryotic cells
Let's see, in the wild and wacky world of eukaryotic cells, the structures that you can find are:
1. Mitochondria - the powerhouses of the cell, also known as the little energy factories. They generate ATP, the cellular energy currency, making sure the cell doesn't run out of juice!
2. Nucleus - the mastermind behind all the cell's operations. It houses the DNA, the blueprint of life itself. It's like the cell's very own mission control center!
Sorry to burst your bubble, but plasmid isn't a structure typically found in eukaryotic cells. It's more of a special extra feature in bacteria. So, plasmids don't quite make the cut when it comes to eukaryotic cells.
So, to recap, the correct answers are: mitochondria and nucleus. Keep it up, cell explorer!
To determine which structures are present in eukaryotic cells, we can examine the characteristics of eukaryotic cells and identify their major components.
1. Mitochondria: Mitochondria are double-membrane-bound organelles responsible for energy production, specifically ATP synthesis, through cellular respiration. They are present in eukaryotic cells and not in prokaryotic cells.
2. DNA: DNA, or deoxyribonucleic acid, is the genetic material found in almost all living organisms. It contains the instructions for building and maintaining an organism. Eukaryotic cells contain DNA, which is organized into distinct chromosomes.
3. Nucleus: The nucleus is a membrane-bound organelle that contains the cellular genetic material, including the DNA. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. Eukaryotic cells have a well-defined nucleus surrounded by a nuclear envelope, whereas prokaryotic cells lack a nucleus.
4. Plasmid: Plasmids are small, circular pieces of DNA that can be found in some prokaryotic cells, such as bacteria. Eukaryotic cells typically do not contain plasmids, as they are more commonly associated with prokaryotes.
Based on the above information, the structures present in eukaryotic cells are:
- Mitochondria
- DNA
- Nucleus
Therefore, the correct answer is:
- Mitochondria
- DNA
- Nucleus
