All biological drawings should be titled. Shading specific areas of a diagram might look aesthetic to the eye, but this practice is not acceptable in biology . Hence, the advice is to AVOID at all cost.
What are the rule of drawing in biology?
Drawings (or diagrams) should be as simple as possible with clean cut lines (do not sketch) showing what has been observed. All drawings should be done on unlined (blank) paper and should be also neatly labelled. 4. Drawings must be large enough to show all parts without crowding .
What makes a good biological drawing?
Technique: Lines are clear and not smudged . Avoid ‘feathery’ pencil lines and gaps. There are almost no erasures or stray marks on the paper. Color is used carefully to enhance the drawing.
What rules do you need to follow to produce a biological drawing of what you see down the microscope?
- Drawn in pencil. Lines should be firm and continuous with no gaps (not sketchy).
- Large with the same proportions as the observed cell.
- Labelled using separate ruled lines. ...
- Given a title that includes its magnification or size.
Why is shading not allowed in biology?
All biological drawings should be titled. Shading specific areas of a diagram might look aesthetic to the eye, but this practice is not acceptable in biology. Hence, the advice is to AVOID at all cost . Try to draw the diagram on a single stroke of the pencil.
What’s a biological drawing?
Biological illustration is the use of technical illustration to visually communicate the structure and specific details of biological subjects of study . This can be used to demonstrate anatomy, explain biological functions or interactions, direct surgical procedures, distinguish species, and other applications.
How do you title a scientific drawing?
Scientific drawings are labeled to show the different features. Title your drawing at the top center of the page with a descriptive title . Include what view is being shown in your title (for example, Top View of a Thermos, Side View of a Thermos, Inside View of My Thermos, etc).
What is the difference between a drawing and a scientific diagram?
Main Difference – Drawing and Diagram
Drawing is the art or technique of representing an object or outlining a figure, plan, or sketch by means of lines. Diagram is a simplified illustration showing the appearance, structure, or workings of something.
What are some branches of biology?
Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology .
How is the beam focused in a light microscope?
The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses , which first focus a beam of light onto or through an object, and convex objective lenses to enlarge the image formed.
What are three rules for drawing specimens from a microscope?
1) Look at the specimen carefully and examine the significant features that will be included in the drawing. 2) DRAW ONLY WHAT YOU SEE!! Do not include what you think you should see. 3) All drawings must be done in pencil ONLY.
What is biology practical?
Biology is a practical science . ... It provides a collection of experiments that demonstrate a wide range of biological concepts and processes. Experiments are placed within real-life contexts and have links to carefully selected further reading.
How do you use a light microscope to observe and draw cells?
- Move the stage (the flat ledge the slide sits on) down to its lowest position.
- Place the glass slide onto the stage. ...
- Select the lowest power objective lens.
- Turn the coarse focus knob slowly until you are able to see the cells.
What are the 5 rules for annotating diagrams?
- Provide an explanation.
- Use simple outline drawings.
- Use a magnifier to show things too small to see.
- Use labels, arrows, and a color key.
- Add notes to explain important ideas.
Why scientific drawing is important?
For public education, scientific illustration is extremely important. It provides a way to share ideas in an engaging and educational way . Artists have the skill necessary to translate scientific information into accessible and understandable artwork that bypasses difficult scientific terms and explanations.
What is Diagramatic drawing?
(dī′ə-grăm′) 1. A plan, sketch, drawing, or outline designed to demonstrate or explain how something works or to clarify the relationship between the parts of a whole.
What is difference between graph and diagram?
Graph is a representation of information using lines on two or three axes such as x, y, and z, whereas diagram is a simple pictorial representation of what a thing looks like or how it works.
Is biology hard to study?
Biology is certainly a hard major but not quite as difficult as other STEM majors such as physics or chemistry. Most students find a biology degree difficult to pursue because it has an extensive syllabus, lots of lab work, several challenging concepts, unfamiliar vocabulary, and lots of things to memorize.
What is the difference between a label and a diagram?
As nouns the difference between label and diagram
is that label is a small ticket or sign giving information about something to which it is attached or intended to be attached while diagram is a plan, drawing, sketch or outline to show how something works, or show the relationships between the parts of a whole.
Which branch of biology is best?

What is light microscope in biology?
A light microscope is a biology laboratory instrument or tool , that uses visible light to detect and magnify very small objects and enlarge them. They use lenses to focus light on the specimen, magnifying it thus producing an image. The specimen is normally placed close to the microscopic lens.
Is light microscope illuminated only with sunlight?
Microscopes are designated as either light microscopes or electron microscopes. The former use visible light or ultraviolet rays to illuminate specimens. ... This is similar to the ordinary light microscope; however, the condenser system is modified so that the specimen is not illuminated directly .
How does a light microscope work a level biology?
The Light Microscope
Light from the Condenser Lens , and then through the Specimen where certain wavelengths are filtered to produce an image. ... Finally, the light passes through the Eyepiece Lens, which can also be changed to alter the magnification, and into the eye.
Can light microscope see viruses?
Standard light microscopes allow us to see our cells clearly. However, these microscopes are limited by light itself as they cannot show anything smaller than half the wavelength of visible light – and viruses are much smaller than this. But we can use microscopes to see the damage viruses do to our cells .
What can’t you see with a light microscope?
You can not see the very smallest bacteria, viruses , macromolecules, ribosomes, proteins, and of course atoms.
How many required practicals are there in biology?
Use of apparatus and techniques
These apparatus and techniques are common to all A-level Biology specifications. Carrying out the 12 required practicals in section 8.2 means that students will have experienced use of each of these apparatus and techniques.
What is spotting in biology practical?
Spotting in practicals means to observe some specimen, identify them and write their important features . In practical examination, you will be provided with different specimen like fishes, bacteria, birds etc. You have to observe (spot) them carefully, then identify them and write their characters. answer. Ad.
How do I prepare for a biology practical exam?
- Study pollen germination on a slide.
- Collect and study soil from at least two different sites and study them for texture, ...
- Collect water from two different water bodies around you and study them for pH, ...
- Study the presence of suspended particulate matter in air at two widely different.
