What is the difference between brain organoids and the real brain?
how might studying these brain organoids patients with these disorders?

Brain organoids is the anatomical resemblance of the mammal brain. It is formed by culturing the stem cells in three dimensional rotational bioreactors. The main difference between the organoids and real brain is the real brain has the connection to outside world to mature in good manner.

The brain organoids are used to apply the genuine experimentation on the brain disorders. It helps in directly studying the tissues and neurons to study disease present in any patients.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
