Science this week

In science this week, we started to learn the funcutions of each cell organell.

We learnt there were two types of cells, a Eukaryotic cell and a Prokaryotic cell.

Eukaryotic cell- a cell that has a nucleas and more parts.

Prokaryotic cell- a cell that has no nucleas{ususly bacteria cells}.

Some of the parts of the Eukaryotic cell are labled on this website.

Some parts of a Prokaryotic cell are labled in the website below.

This is a picture comparing a prokaryotic cell and an eukaryotic cell.{right}

We also studied DNA. DNA is made up of Dioxyribos nuclear acid. There is two strands of sugar strands and the middle is made up of hydrogeon bonds. The DNA is spiraled and makes a doubel helix. This is how it looks:{below}
