In sponges fertilization takes place in____________?
Correct answer: B. Mesenchyme
- A. Ectoderm
- B. Mesenchyme
- C. Endoderm
- D. Uterus
Explanation
In sponges, sperm released into the water are captured and carried into the mesenchyme or mesohyl, where fertilization occurs. This internal gelatinous region contains the reproductive cells and amoeboid transport cells. Students may choose c by assuming fertilization occurs in the digestive lining, but sponge fertilization takes place in the mesenchyme.
