Why Is It More Useful To Stain Eukaryotic Cells?
Why is it generally more useful to stain eukaryotic cells than prokaryotic cells? Specific stains can reveal certain compounds or structures within a cell. Eukaryotic cells are more complex then prokaryotic cells and have more structures that can take in the stains.
Why is it generally more useful to stay in eukaryotic cells and prokaryotic cells?
To study cells with a light microscope different types of stains are usually available. Why is it generally more useful to stain eukaryotic cells than prokaryotic cells? L Stains work better for eukaryotic Cells because they have more internal structures z to hold the stain more to see.
What methods would you use to study the structure of eukaryotic cells?
The two most common methods for visualizing living cells are phase-contrast microscopy and differential interference-contrast microscopy (Figure 1.26).
What is a difference between prokaryotic and eukaryotic cells?
Which cell looks more clear when it is observed through a microscope Why?
In practical terms bacteria and mitochondria which are about 500 nm (0.5 μm) wide are generally the smallest objects whose shape can be clearly discerned in the light microscope details smaller than this are obscured by effects resulting from the wave nature of light.
Why are eukaryotic cells more complex than prokaryotic cells?
What are the advantages of eukaryotes over prokaryotes?
The major structural advantage of eukaryotes over prokaryotes is the ability to form advanced multicellular organisms. While eukaryotes can survive as both single-cell and multicellular organisms prokaryotes don’t have the ability to form complex structures or organisms.
What are eukaryotic cells used for?
What is the importance of a microscope in the study of the cell structures?
A cell is the smallest unit of life. Most cells are so small that they cannot be viewed with the naked eye. Therefore scientists must use microscopes to study cells. Electron microscopes provide higher magnification higher resolution and more detail than light microscopes.
Why are microscopes important when studying cells?
What characteristics do eukaryotes have that prokaryotes lack?
Eukaryotic cells contain membrane-bound organelles such as the nucleus while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts the cell wall and the structure of chromosomal DNA.
How are eukaryotic cells different from prokaryotic cells select the two answers that are correct?
How are eukaryotic cells different from prokaryotic cells? Select the TWO answers that are correct. Prokaryotic DNA is contained in the cytoplasm whereas eukaryotic DNA is contained in the nucleus. How does the DNA of prokaryotic cells differ from the DNA of eukaryotic cells?
How do prokaryotic and eukaryotic cells differ quizlet?
What is the difference between Prokaryotic and Eukaryotic cells? Eukaryotic cells have a true nucleus and have membrane bound organelles Prokaryotic doesn’t. … Both contain DNA has a cell membrane has cytoplasm has ribosomes and cell wall (eukar-plant only).
How does a microscope help in viewing cells?
In general a “microscope” consists of a series of lens that helps us to magnify an image many times. This high magnification enables us to focus and see clearly the images of micro organisms. The cells have to be prepared in such a way that they will be visible under the microscope.
Which microscope achieves the highest magnification and greatest resolution?
What stain is used to observe mitochondria?
Why eukaryotic cell is structurally more complex and compartmentalized than a cell that is prokaryotic?
Prokaryotic cells are in fact able to be structurally more simple because of their small size. … That is why eukaryotic cells require a variety of specialized internal organelles to carry out metabolism provide energy and transport chemicals throughout the cell. Both however must carry out the same life processes.
What are the advantages to being eukaryotic?
The major advantage of being eukaryotic is that of having compartments (organelles) with specialized functions (and thus division of labor). Another advantage is that cells can be much larger without surface area-to-volume considerations being critical because of compartmentalization.
What is an advantage of eukaryotic cells having internal membranes?
Membrane-bound organelles offer several advantages to eukaryotic cells. First cells can concentrate and isolate enzymes and reactants in a smaller volume thereby increasing the rate and efficiency of chemical reactions.
Which is an advantage of eukaryotic cell structure over prokaryotic cell structure quizlet?
Which is an advantage of eukaryotic cell structure over prokaryotic cell structure? Different cell functions are compartmentalized and kept separate from one another in membrane-bound organelles in eukaryotic cells.
Why are prokaryotic cells important?
What is the function of prokaryotic cell and eukaryotic cell?
| Cell Component | Function | Present in Prokaryotes |
|---|---|---|
| Nucleoid | Location of DNA | Yes |
| Nucleus | Cell organelle that houses DNA and directs synthesis of ribosomes and proteins | No |
| Ribosomes | Protein synthesis | Yes |
| Mitochondria | ATP production/cellular respiration | No |
Why should plant and animal cells need to be eukaryotic cells?
Both plant and animal cells are eukaryotic so they contain membrane-bound organelles like the nucleus and mitochondria. The nucleus of eukaryotic cells is similar to the brain of the cell. … For example plant cells contain chloroplasts since they need to perform photosynthesis but animal cells do not.
How did the microscope help lead scientists to develop the cell theory?
It made it possible to actually see cells. Explanation: With the development and improvement of the light microscope the theory created by Sir Robert Hooke that organisms would be made of cells was confirmed as scientist were able to actually see cells in tissues placed under the microscope.
How does electron microscope affect cells?
Electron microscopes are the most powerful type of microscope capable of distinguishing even individual atoms. However these microscopes cannot be used to image living cells because the electrons destroy the samples. … Damage would be avoided because the electrons would never actually hit the imaged objects.
Why do scientists use stains to study cells?
The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope. Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample.
Why is microscope important in microbiology?
The microscope is absolutely essential to the microbiology lab: most microorganisms cannot be seen without the aid of a microscope save some fungi. And of course there are some microbes which cannot be seen even with a microscope unless it is an electron microscope such as the viruses.
Why is it important for multicellular organisms to have specialized cells?
Multicellular organisms need many different types of cells to carry out the same life processes. Each of these special types of cells has a different structure that helps it perform a specific function. … Cell differentiation is the process by which cells become specialized in order to perform different functions.
What do eukaryotic cells have that prokaryotic cells lack quizlet?
What do eukaryotic cells have that prokaryotes lack? A nucleus and other internal organelles. … At a molecular level the members of the two domains of prokaryotes—the archaea and bacteria—differ as much from each other as either does from the eukaryotes.
What are the main features of a eukaryotic cell?
Which if the following are found in eukaryotic cells but not prokaryotic cells?
Does a prokaryotic cell or eukaryotic cell seem more simple?
Prokaryotic cells (Figure below) are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles.
Why are eukaryotic cells unaffected by streptomycin and similar antibiotics quizlet?
These antibiotics interfere with DNA replication. Why are eukaryotic cells unaffected by streptomycin and similar antibiotics? A.) Eukaryotic cells are unaffected by these antibiotics because eukaryotic cells lack cell walls.
Why are eukaryotic cells unaffected by streptomycin and similar antibiotics?
b.
Streptomycin does not stop protein synthesis in eukaryotic cells because it does not bind to eukaryotic ribosomes. Penicillin and vancomycin inhibit enzymes required for formation of the bacterial cell wall a structure that bacterial cells have but animal cells do not.
