Prokaryotic Cells
What is a prokaryotic cell?
Small cells that don't have a nucleus.
What are the main characteristics of a eukaryotic cell?
The Nucleus
Where is DNA found?
Inside the nucleus of cells.
What is a virus?
It is a small, submicroscopic particle that causes infections.
What is photosynthesis?
It is the process by which green plants, algae, and some bacteria use sunlight, water, and carbon dioxide to make their own food (glucose) and release oxygen.
What is the main type of prokaryotes?
Bacteria.
What is the main function of the nucleus?
It acts as the control center.
What is the shape of DNA?
A double helix, which looks like a twisted ladder.
How do viruses make you sick?
They enter your body, attach to healthy cells, and take over.
Where does photosynthesis take place?
Inside specialized, tiny structures called chloroplasts found in plant cells, particularly in the leaves.
How do prokaryotes reproduce?
Binary Fission.
Where is most of the cell's DNA located?
Inside the nucleus.
What is a gene?
A specific section of DNA that tells the cell how to make a specific protein.
What is a "host"?
A host is a living cell (human, animal, plant, or bacteria) that the virus infects to survive.
What is chlorophyll?
Chlorophyll is the green pigment in chloroplasts that absorbs light energy from the sun.
Are prokaryotic cells unicellular or multicellular?
Unicellular
What defines a eukaryotic cell?
They have a true nucleus.
What is the job of DNA?
It acts as an instruction manual or blueprint for building and operating an organism.
How are viruses spread?
They spread through coughing, sneezing, contaminated water/food, or by touching contaminated surfaces.
What do plants do with the glucose?
Plants use glucose for energy to grow, and they store extra glucose as starch.
True or False Prokaryotes make up a clade?
False
How do eukaryotic cells divide?
Through mitosis
What does DNA stand for?
Deoxyribonucleic acid.
Are viruses living organisms?
No.
Why is photosynthesis important?
It provides food for plants and animals, and releases oxygen into the air, which humans and animals need to breathe.
