Amoebas are single-celled protozoans that move and feed via pseudopodia, while hydras are multicellular freshwater cnidarians with a simple tubular body and tentacles.
The green color arises from Chlorella-like cells, unicellular algae each occupying a vacuole in the endodermal cells of their hosts. Each endodermal cell contains 10–35 algae-laden vacuoles (Fig. 8). The precise number varies with species, but is nearly constant within a hydra strain and ...
Addition of short RNA leader sequences to the 5′ ends of messenger RNAs bytrans-splicing occurs in a subset of metazoans and unicellular eukaryotes9. Transcripts from at least one-third of EST-supported genes inHydraundergotrans-spliced leader addition (Supplementary Information section 10).Hydraha...

Multicellular animals must coordinate the activities of physically-separated effectors, such as the movements of multiple tentacles in Hydra. This coordination can be achieved in three ways. The first, a seemingly straightforward extension of the chemical communications of unicellular eukaryotes, is for ...
Budding is a type of asexual reproduction, commonly associated in both multicellular and unicellular organisms. Bacteria, yeast, flatworms, are a few species which reproduce through budding.
