i just can say...it was amazing!!!

as usual, i have experiment for biology...

for this time, i had to observe the process of mitosis and the movement of chromosome itself...

we had learn about this starts from form 1 is it????

actually it was quite hard to get a very clear image of this cells...

sometimes,the cells were overlapping and we had to handle it carefully..

the process of maceration are very important to make sure that the chromosome of the cells are clear..

actually,my group did not get the real result because almost the cells were overlapping...

so the movement of chromosomes were not clear and we can't calculate its size

this images were from the others group and i just could say

'subhanallah' it was amazing!!!!

i could see the movement of chromosome in the cells by myself..

before this i just learn the theory of mitosis...

this is prophase

.

.

no pics for metaphase in which the chromosome are line up on the equator

anaphase...the centromere seperates and the chromosomes moves to opposite poles

.

telophase....new cell formed

these are the pics of garlic root cells...

interesting right???this is the images from a camera...

it was quite hard to take the pics through the microscope...

but,these are great enough...biology is fun

I LOVE BIOLOGY

p/s:credits to the group that prepare these cells,to the photographer &to toluidine blue which makes the chromosomes appear(can be seen)

our fibres was missing.....who's fault???? maybe someone had stolen it

i made an experiment about tensile strength last week...what is tensile strength???
Tensile strength is the maximum stress caused by a pulling force that a material can stand without failing. Tensile strength is measured in units of force per unit area. in this experiment,we use the pumpkin stem fibre to measure measure the tensile strength...


we also can prove that the tensile strength of plant fibre is stronger than concrete...is it a fact???yes!!actually it is proven through our experiment and based on the theory...we had to soak the pumpkin stem for about a week and this process is called retting..we could get the fibre inside the stem~


we had a sad story regarding this experiment actually...as we got one week holiday for CNY, we had no enough time to soak the the stem during the lab class,which was on Friday...so,we just took about half of an hour to soak it during our free time...as we had to dry it,we just left the fibre in the lab because the lab assistant promised to keep it inside the preparation room..


the next lesson,on friday
our fibre was missing!!!MIA!!!how to conduct this experiment without the fibre????the lab assistant said that she had kept our fibre safely,but she didn't know how it could be 'stolen'by others..sob..sob..luckily,there were a few fibres less..so we had to divide the fibre among ourselves equally..huh!!we also picked up the fibres on the floor..so pathetic is it?????


finally,we could finish our experiment successfully...although it was quite hard because we did not have enough fibres, but with our persistent,we could make it happen!!!i was so glad...we also need to measure thee diameter and length of the fibres to unsure that all of them were quite similar and  our result was reliable...


p/s=the process of making biology report is quite tough than doing the experiment

USE THE HOLIDAY TIME WISELY

this week is the mid-sem break and i got a week holiday....owww yeah!!!!!!!jaa,wake up...don't waste your time....this is not the time for relaxing and loitering anywhere....this is the time to make revision about the subjects that i do not understand before...i'll try my best.....

YOU CAN DO IT

friends forever

suddenly i thought about  them....my dorm-mates during form 4 and 5 at sesma.....friends forever okeh!!!
