Question

Choose the correct answers from the alternatives given.
Press a sponge through a coarse cloth bag and extrude the whole cells through the holes. The cells then:

• A. reproduce sexually
• B. die from being separated
• C. form spicules in the pattern of the cloth
• D. reassemble into a new organised sponge with each cell resuming its original job

Answer 1

The correct option is D reassemble into a new organised sponge with each cell resuming its original job

The extraordinary capacity of sponges to regenerate is manifested not only by restoration of damaged or lost parts but also by complete regeneration of an adult from fragments or even single cells. Sponge cells may be separated by mechanical methods e.g., squeezing a piece of sponge through fine silk cloth.The dissociated cells then settle, migrate, and form active aggregates in which the archaeocytes play an important role.

So the correct answer is "reassemble into a new organised sponge with each cellresuming its original job".
