Biology- e-learning portal --Photosynthesis and plant organs

Hi Students,

Here is the fifth list of sites you can go to to learn science in a fun way.
The site is good for quick revisions and introductions to the topics.


Topic: Photosynthesis and plant organs

1 experiments to see if chlorophyll and light are needed to make starch

2 the role of the leaf in photosynthesis

Photosynthesis- energy in a plant, by Leslie Samuel

Hi,

Watch this video for a very detailed description of the process.

Why is the sky blue?

Hi,

All children ask this question sometime in their lives.
The sky is blue as more of the blue colour in the light spectrum is scattered by the atmospheric gases.
Why is leaf green? Why is the sea blue?
Get the explanations from this Discovery News video.

Sea slug that could do photosynthesis?


Hi,


Look at this marine slug, a shell-less snail. It is green as it has chloroplasts. It can make its own food by photosynthesis.


Read how this organism has accomplished this marvelous feat. Click on the link below to find out more about it. Green sea slug is part animal, part plant.


Scientists led by Dr Sidney Pierce found that this slug contained chloroplasts containing chlorophyll taken from an algae by the name of Vancheira. Once the slug has enough chloroplasts under its skin, it does not have to eat for the rest of its life. Just like a plant does not eat food.


Why cannot we also have chlorplasts so that we do not have to eat, but just absorb energy for all our needs from the sun like greeen plants?


Bizarre.


Cheers
