Cells and Biological Molecules

Assignment brief

Task 1: Cells and Biological Molecules workbook (1.1-7.2) 2000 words

The workbook should be fully completed using Calibri font size 11. Answer questions as fully as you can, in detail and try to find additional information to add breadth and depth to the work. Relate structure to function where relevant. Remember to reference the work correctly in-text, and include a reference list at the end (ask if you are unsure). You will need to either scan or photograph your microscope drawings and insert them into this document in the appropriate place. You should ensure they are high quality and clear to see. A reference list should be added on a separate page at the end of this workbook. Any additional diagrams referred to, to help with explanations, must be referenced and placed in appendices (ask if you do not know how to use appendices).

Task 2: DNA and RNA structure, and the process of protein synthesis Presentation (8.1-8.2) 500 words

You will create and present a presentation using detailed scientific diagrams and pictures which are referenced correctly. The presentation should aim to describe the structure and function of DNA and RNA. It should also explain the process of protein synthesis, including the enzymes involved. Your teacher will mark your presentation primarily on the quality of the content and diagrams used, however, your ability to convey this information to an audience in a professional manner will also be assessed.

Hand in

The assignment should be uploaded onto Moodle no later than 9am on the deadline day. Late submissions will be automatically capped at a pass.

For this assignment you will be graded on the following grade descriptors: 1, 2, 7.

There are no descriptor statements for a Pass. Students achieve a Pass by meeting the requirements of all the assessment criteria of a unit.

If work is submitted after the formal deadline has passed, and no extension has been granted, all grade indicators relating to this assignment are capped at a Pass.

(1.2) Use comparisons of particular cell components to specify the key differences between prokaryotic and eukaryotic cells. An example has been given.

Prokaryote cell Eukaryotic cell

Mesosome for energy production Mitochondria for energy production

DNA in prokaryotes is just one primary circular chromosome with various plasmids and is stored within the cytoplasm Have a membrane-bound nucleus where DNA is stored and is condensed into double-stranded chromosomes

Prokaryotes are unicellular (incoude def) Eukaryotes are multi-cellular

Locomotive structures in this cell compose of repated flagellin, hook and motor complex All eukaryotes undergo mitosis and the sexually reproducinhg eukaryotes undergo meisos

(250 words for a) and b)).

For two of the prokaryotic cell components you have identified, explain how their structure is related to their functions.

For two of the eukaryotic cell components you have identified, explain how their structure is related to their functions

Animal and Plant Cells

(2.1) Add ticks to the table to show whether these features apply to plant cells/animal cells or both.

Feature Animal cell Plant cell Both

Cell wall Cell membrane Lysosomes Chloroplast Mitochondria Starch granules Ribosome Golgi body Permanent vacuole (2.2) (4.3) For a specialised animal cell and plant cell of your choice, explain how the structural features, specific to that cell type, relate to the cells function within the organism (200 words).
