Intro to Cells quiz 1.1
This is a quiz of multiple choice style questions well-nigh the introduction for cells topic one.1.
They are self-marking questions, so you can click on 'check' to see whether yous take the answer correct.
Each question has a helpful note written past an examiner. Slap-up for revision.

The 'Cell theory' states that all living things are made of cells.
Which of the statements below besides class part of the 'prison cell theory'?
According to jail cell theory, living organisms are composed of cells.
Cells come from pre-existing cells and cells are the smallest using of life.
Some people say that the cell theory isn't a good theory because at that place are exceptions.
Which of the following could be considered an exception to cell theory?
Exceptions to prison cell theory are : multinucleated striated musculus the behemothic single celled Acetabularia algae?
Likewise, organisms consisting of but one prison cell acquit out all functions of life in that cell. eastward.chiliad. Paramecium, Chlorella.
There are seven processes which are said to be possessed by all living things.
This venus wing trap has just caught an unfortunate wing. The wing is trying to escape from the trap.
Which characteristic of living things, shared by both plants and insects, is illustrated past the action in this photo?
The characteristics of living things (Mr H. Gren - metabolism, response, homeostasis, growth, reproduction, excretion & nutrition)
The wing is responding to the closing trap, and the trap has responded to the presence of the fly.
Which ratio is thought to limit the size of cells?
Surface area to volume ratio is important in the limitation of cell size.
When musculus cells form cardiac muscle tissue in the centre they tin can pump blood.
If you but ever studied individual cardiac muscle cells you would never see the claret pumping properties.
What is this type of holding called?
Multicellular organisms have properties that sally from the interaction of their cellular components. (Emergent properties)
A single stalk cell can form a range of different daughter cells.
Which of the statements best describes how this happens?
Specialised tissues tin can develop by cell differentiation in multicellular organisms.
Differentiation involves the expression of some genes and not others in a jail cell.
Which of the following are special properties of stalk cells which make them so useful for new medical treatments?
Stem cells can carve up and this aid researchers to grow them in the lab.
They can differentiate along different pathways in embryonic development which makes stalk cells useful for therapeutic uses (due east.g. Stargardt'southward illness) because they can be grown into many different tissues.
The electron microscope image below shows a scale bar marked with 10µm.
Information technology has been measured to exist 3.5cm (i.e. 35 mm) long by a educatee using the rule shown.
What is the magnification of the paradigm?
Calculate the magnification of an electron microscope image from a scale bar?
Convert the ruler measurement to the same units written on the calibration bar,
so divide the ruler measurement past the number on the scale bar.
The image beneath shows a small food vacuole in a cell.
Using the scale bar, approximate the bore of the vacuole. Which reply is the all-time estimate
Calculate specimen size using a scale bar?
You tin often estimate the size using the scale bar and your thumb?
The erythrocytes below were imaged using an electron microscope.
The magnification is x3000 and the ruler measures the central cell as existence 2 cm in diameter.
Estimate the actual size of this erythrocyte.
Summate specimen size using magnification?
Beginning change the size measurement into µm units = 20000µm
Then divide by the magnification. 20000 / 3000 = twenty / iii = 6.half-dozen µm
Some people are excited most the potential benefits from stem cell research and other people have deep concerns.
Which of the following is not a potential benefits of the apply of stem cells?
In that location are ethical concerns about the utilise of embryo stalk cells.
The research is expensive, and potential treatments are also probable to exist expensive, and probably not available to all.
Many people who are confronting stem cells say that information technology is because cells are taken from human embryos, which have the potential for man live, and should be protected. There are other sources of stem cells, they argue.
