Movement of Substances..

Reminder:

Favourite chapter : Has been frequently asked in Paper 2 from 2006 - 2010 .

Please go through the content checklist which you might need for your final revision prior SPM 2011.

PAPER 2:

§Qs7 2006-Define plasma membrane exhibits fluidity and Interpret graph related to different concentration.(ESSAY)

§Qs2 2007- Plasma membrane Diagram-active and passive transport/ characteristics of phospholipid bilayer

§OSMOSIS-HYPO/HYPER/ISO- Paper 3 Qs2- (2005&2006)

§Plant cell in concentrated salt solution (2009, 2010)

§Similarities and differences between facilitated diffusion and active transport

(2008- 8m)

Take Note:

Discuss the processes of passive transport and active transport in living organisms:

i. gaseous exchange in the alveoli and blood capillaries (simple diffusion).

ii.absorption of digested food in the villus (facilitated diffusion)

iii. absorption of water by root hairs of a plant ( osmosis)

iv.ion intake by root hairs of a plant ( active transport)

*Compare and contrast passive transport and active transport.

* **Explain the effect of hypotonic, hypertonic and isotonic solutions on plant cell and animal cell.

* ***Explain plasmolysis, deplasmolysis, heamolysis and crenation.

♠ Study Tips

Early Morning hours is the best time to study as you wake up refreshed away from all sorts of disturbances. The ions in the environment is said to be lower in the early mornings hours (3 am - 6 am ) which makes the morning hours the best time to study more things in the least possible time. Here are 3 other reasons why morning hours is the best to study.

1.You wake up refreshed - Early in the morning you wake up refreshed and stays clear headed. I advise this based on my experience as I was able to learn any amount of topics in the morning compared to evening hours.

2.Helps better memory - After sleep, processing and learning is said to improve based on recent studies. Revising your lessons early morning helps to remember the contents on a specific topic better.

3.Helps better focusing - There will be very less distractions in the morning compared to any other time of the day and a focused learning is possible in the morning.
_______________________________

The ideal time of morning hours of 3 am - 6 am is said to be the best time. A half an hour nap afterward will help you to better refresh your mind. Avoid learning for more than 3 hours in a stretch and take some short breaks of 10 minutes in between your study time.
