Topic: Cells

3 main concepts I have learnt. You may list more. You are encouraged to use mutlti-media to enhance the post. ·         How to differentiate the smooth endoplasmic reticulum and the rough endoplasmic reticulum. ·         Difference between the nucleus and nucleolus. ·         Ribosomes are found in the endoplasmic reticulum and they make proteins from amino acids. http://student.ccbcmd.edu/~gkaiser/biotutorials/eustruct/u1fig31.html	Identify 3 links this topic/concept has with something I have learnt before (can extend beyond Science) Learnt about chromosomes only in the past but now, we learnt about chromatin. The two are similar but chromosomes are twisted, curled and coiled while chromatin is not. Learnt only about the nucleus in the past but now we learn about the nuclear pores, which are pores that allow exchange of materials between the nucleus and the cytoplasm. Mitochondrion supplies most of the cell’s chemical energy.
2 things/(questions) I am unsure about/(have). You may list more. (a)   Not that clear about what the secretion vesticles are for. (b)   Unclear about the function of the lyosome.	Where is this topic/concept applied in daily living? (Give at least 2) Applied in daily life as cells are responsible for our growth, repairing and reproduction of new cells. Transporting molecules throughout our body.
1 extended concept I am interested to research on /read more about: -       How cells communicate.	Common misconceptions(mistakes) OR scientific phrases that are important (Give at least one) Differentiating the smooth endoplasmic reticulum and rough endoplasmic reticulum.

What I am going to do to clarify my doubts? List the steps you are going to do and date you intend to complete them:

Concepts/Things I am still unsure about	What I am going to?	Date I intend to get it done	Completed (J when its done!)
(a)   Unclear about the function of the lyosome.	-       Read through again the notes my teachers gave, research online and ask the teacher if I am still unsure.	09/08/2011
(b) Not that clear about what the secretion vesticles are for.	-       Read through again the notes my teachers gave, research online and ask the teacher if I am still unsure or seek help from peers.	09/08/2011

My feelings and thoughts about class today: interesting as everything we learn about is related to our body.  And we get to see things we cannot see with the naked human eye.
