Cells
-
-
-Chloroplast-
Contains chlorophyll to trap sunlight for photosynthesis to make food and oxygen. Cells with chloroplast do not depend on other organisms for food/energy.
-
-
Root Cell VS Lead Cell
Root cells do not have chloroplast as they are not exposed to light and do not undergo photosynthesis
Cell
A cell is a basic unit of life that can control it own activities.A cell is a living thing and can grow, needs food and responds to changes and reproduce
Digestion
Digestive juices
The Amount of digested food is more when leaving small intestine than large intestine
All the digested food will be absorbed into the bloodstream at the small intestine
Hence there is no digested food present at the large intestine
Gullet
No digestion occurs here
No digestive juices are added Helps to bring practically digested food from the mouth to the stomach
-
-
Small intestine
Digestion is complete here
Digested food is absorb into the bloodstream
Undigested food is passed to the large intestine
-
Teeth
We chew our food into smaller pieces to increase the surface area for digestive juices to work on
This allows digestion to happen faster
Experiment
-
Control Set-Up
This is to compare and confirm that any changes in the (dependent variable) is only due to changes in the (independent variable) and not any other other variables
Dark Room
Carrying out the experiment in a dark room ensures that (light source) is the only light source and that the amount of light remains the same as this affects the (results)

Float
GF vs MF
the magnetic force of repulsion must be greater than the weight of the object, pulling it down

-
Electricity
-
Bulb in parallel
Advantage
-
iI one bulb fuse, other will still light up
-
Batteries in parallel
-
Disadvantage
When one is removed, others will still continue to power the bulbs to shine
