What are the different parts of a eukaryotic cell?
What are the different parts of a eukaryotic cell?
Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells.
How do eukaryotes differ from each other?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.
What are most eukaryotic cells made up of?
Eukaryotes and prokaryotes
| Feature | Eukaryotic cell |
|---|---|
| Outer layers of cell | Cell membrane, surrounded by cell wall in plants and fungi. |
| Cell contents | Cytoplasm, cell organelles include mitochondria, ribosomes and chloroplasts in plants. |
| Genetic material | DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. |
What parts of cells are unique to eukaryotes?
Eukaryotic cells contain 80S ribosomes in the rough endoplasmic reticulum (membrane bound-ribosomes) and cytoplasm (free ribosomes). They contain 70s ribosomes in mitochondria and chloroplasts. Eukaryotic cells have evolved an endomembrane system, containing membrane-bound organelles involved in transport.
What are the 2 types of eukaryotic cells?
Eukaryotic cells may be classified into two groups based on the number of cells that make an individual organism: (1) unicellular eukaryotic cells and (2) multicellular eukaryotic cells. Unicellular eukaryotes include the protists. Multicellular eukaryotes include a variety of plant, fungal, and animal species.
Do viruses only target animals?
Viruses require a host to reproduce. Viruses only target animals (which includes humans). All of these viruses would still have genetic material, either in the form of DNA or RNA. They also would have a protein coat known as a capsid.
