Welcome

This is Key Stage 4 Biology ~ GCSE.

Welcome to my new look Gondar Design Biology website. This is just one of seven sections at Gondar Design Science. In the move from NetBenefit to Easyspace I have altered the settings and code to remove “wordpress” from the URLs, so the facebook like buttons have been reset to zero. If a seach engine points you to a URL with “/wordpress/” the server will strip this out, but if it points to an HTML page, ie “….htm” you can delete the filename to get to the subject folder. Here you can post comments or ask questions on almost every page. Please register first.

We do NOT use your email for any purpose other than
to send you a password or password reminder.

Use the links on the right of any page to navigate the separate sections of the site.

The photograph at the top of each page in the Biology section of my site was taken here at Mitchell’s Elm House. What a lot of biology is going on here! Think about all the tiny worms, insects and other creepie crawlies in these leaves, not to mention the photosynthesis in the trees above.

    excellent site

    explain why are sugars stored as starch and not as simple sugar?

  2. Nigel says:

    Hi Nazneen,

    Firstly, starch is not soluble, so it cannot get out of the cell: glucose is soluble so it would leak out of the cell. Storing glucose in a cell would be like trying to fill a bag made of netting with water.

    Secondly one molecule of starch has the same osmotic effect as one molecule of glucose, but many thousands of glucose molecules are joined together to make a molecule of starch. So a cell full of glucose (many thousands of molecules) would swell up by osmosis and burst, but a few starch molecules will not do this. i.e joining all the glucose molecules together takes the osmotic effect away.

    Great website!

    hi im new and i would like to know how to work the raspberry pi because its totally lost me.

    • Well this is not a biology GCSE question even though it is a raspberry!
      If you have connected the display, keyboard and a mouse, all you need to do is plug in your SD card. You can also connect the Raspberry Pi to the internet via your modem or router. The SD card can be purchased already loaded with suitable software, or you can download a software image to a blank SD card from the internet.

      Have a look at my section on Investigations. This site is intended for GCSE students NOT Advanced level: even so the investigations section will give you some guidance.
