Which of the following is true about sponges and placozoans? a. They are both bilaterally symmetrical with endoderm, ectoderm, and mesoderm.
b. They are both asymmetrical. Placozoans have endoderm and ectoderm while sponges have no tissue.
c. They are both asymmetrical with endoderm and ectoderm.
d. They are both radially symmetrical with no tissue.

d. They are both asymmetrical. Placozoans have endoderm and ectoderm while sponges have no tissue.

Explanation:

Placozoans and sponges are both animals with asymmetrical body plans. They differ in that placozoans are slightly more complex than sponges because placozoans have embryonic tissue layers: endoderm and ectoderm. Sponges have no tissue.
