The drfinite shape to ciliates is given by____________?
Correct answer: A. Pellicle
- A. Pellicle
- B. Penicle
- C. Calcium
- D. Cell wall
Explanation
A pellicle is a firm but flexible protein-rich covering beneath the cell membrane of ciliates, and it maintains their definite shape while allowing movement. Students may choose a cell wall because walls also provide shape in many organisms, but ciliates do not have a typical cellulose cell wall. The submitted key matches.
