Science prokaryots and ekaryots quiz

If you were looking at a cell with a microscope, how would you know if you were looking at a prokaryotic cell or eukaryotic cell?

If you were looking a at cell with a microscope you would look for a nucleus to determine if it is a prokaryotic cell or a eukaryotic cell. If the cell has a nucleus, it is eukaryotic.

If you were looking at a multicellular organism with a microscope, would you be looking at a prokaryotic or eukaryotic organism? How do you know?

If you examine a multicellular organism with a microscope, you would know you were looking at a eukaryotic cell because prokaryotes are always unicellular.

Asexual

A reproductive process that involves only one parent and produces offspring that are identical to the parent. They include binary fission, fragmentation, and budding.

Sexual

A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents

What are two examples of organisms with prokaryotic cells?

Bacteria, archaea, and cyanobacteria (blue green algae) are prokaryotic cells.

How are prokaryotic cells and eukaryotic cells alike?

Both prokaryotic cells and eukaryotic cells are the basic building blocks of organisms. They both contain a cell membrane, cytoplasm, ribosomes, and DNA. Both types of cells need energy and carry out life functions like growth and reproduction. Unicellular organisms can be either a prokaryotic or eukaryotic cell.

If you were looking at a unicellular organism with a microscope, would you be looking at a prokaryotic cell or a eukaryotic cell?

If you were looking at a unicellular organism with a microscope, you could only tell if it were a prokaryotic or eukaryotic cell if you could see a nucleus; there are unicellular organisms that are prokaryotic and unicellular organisms that are eukaryotic. The eukaryotic cell would have a nucleus. You might also be able to predict the cell type based on the size of the cell.

What are two examples of organisms with eukaryotic cells?

Plants, animals, fungi, and protists (examples: amoeba, paramecium, euglena) are made up of eukaryotic cells.

How are prokaryotic cells and eukaryotic cells different?

Prokaryotic cells and eukaryotic cells are different in that eukaryotic cells have the DNA stored inside a membrane-enclosed nucleus, whereas, in prokaryotic cells, the DNA is free in the cytoplasm and is not membrane-enclosed. Eukaryotic cells are more organized and complex; they have more cell structures that are membrane-enclosed organelles, such as a nucleus, chloroplasts, endoplasmic reticulum, mitochondria, and vacuoles. Prokaryotic cells are less organized with fewer cell structures and do not have membrane-enclosed organelles. Prokaryotic cells are typically smaller and are only unicellular organisms, but eukaryotic cells are typically larger cells and can be found in either unicellular or multicellular organisms.
