Question

1) name the group of organisms where a pulsatile organ pumps blood ?

2) in which organism, highly branched digestive system transport the materials ?

3) what is the difference between pseudocoelom and eucoelom.

4) why do you think unicellular organisms lack special organs for transport ?​

Answer 1

Answer:

2nd one is platyhelimenthis

4th one is because the work which we do is with all the body parts but unicellular organisms only have one cell to do these all works

Answer 2

1) Anthropods are the group of organisms where pulsatile organ to pump the blood directly to the tissues.

2) Platyhelminthes organisms have a highly branched digestive system to transport the materials.

3) Pseudocoelom is related to the phylum Nematoda.

Eucoelom is related to the phylum Annelids.

Pseudocoeloms are the triploblastic animals. The body cavity divided into three layers. Those are ectoderm, endoderm, and modern.

In Eucoelom the body cavity is lined by mesoderm.

4) Unicellular organisms lack special organs to transport because they have only one cell so special organs are not formed.

Unicellular organisms have a type of transport system that is Brownian movements.
