There was an interesting story by @sakshiconsultant2002
On 27/7/2022 she made a single line culture for one hydra ,later on 22/8/2022 that became 19 hydras .
Then the disscussion turned into the structure of hydra .
In this picture we can see a enlarged portion of gastric region , that is divided into
1)Outermost layer:Ectoderm
2)Middle :Mesogloea
3)Inner :Endoderm
Then we noticed that the Stem cells is distributed evenly in body column so that is helpful for the regeneration of hydra .
The previous experimental results are also showing that , if we cut the hydra in to three 1) head portion 2) middle portion and 3) tail portion each of them will regenerate because of this stem cells .
Yesterday the discussion was started with Hydra initiated by @SakshiThe Ratnam college group received Hydra and Moina from @dhanraj.tribhuvan@sakshi @Archita15 made a setup for observing feeding habit of Hydra .@dhanraj told them that ,one moina is enough to feed for one hydra .@Sakshi made a experimental setup that include 1:3 ratio for feeding .For 1 hydra 3 moina were added to the bottle .
The set up include :
Two seperate plastic container with 1:3 ratio of feeding ,marked as experiment and replicate .
One control is with 1:1 ratio (Dhanraj formula )for feeding .
For this experimental setup three plastic container were used .Also made some holes on the top of the aluminium foil for aeration .
The plastic container with 15 ml of dechlorinated water was used .one Container with 3 hydra each .
Then the disscussion was about the red moina . that, more than one drop of a milk make moina red .
This cause the increasing in the number of bacteria there by decrease the amount of oxygen .
In order to cope up this ,Moina will produce more hemoglobin .
