Which of the following statement about eiliates in incorrect_____________?
Correct answer: D. Diploid nucleus being smaller is responsible for cells metabolism and growth while polyploidy nucleus functions in sexual process.Biological Sciences
- A. Contain mainly unicellular organisms.
- B. Their contractile vacoule is respobsible for water regulation.
- C. They are even capable of sexual reproduction.
- D. Diploid nucleus being smaller is responsible for cells metabolism and growth while polyploidy nucleus functions in sexual process.Biological Sciences
Explanation
In ciliates, the diploid micronucleus is involved mainly in sexual reproduction, whereas the usually polyploid macronucleus controls metabolism, growth and everyday cell activities. Option d reverses these functions, so students may instead select b if they misunderstand that the contractile vacuole regulates water balance rather than respiration.
