Biology- e-learning portal --cells, organelles and organisation of living things

Hi Students,

Here is the second 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.

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
