Haploid tube cells:
Correct answer: C. Produce proembryos
- A. Quinine
- B. Direct way to produce plants
- C. Produce proembryos
- D. Releasing haploid embryos
Explanation
The haploid tube cells with in the pollen grains divide, producing proembryos consisting of as many as 20 to 40 cells. Finally the pollen grains rupture releasing haploid embryos. The experimenter can now generate a haploid plant, or chemical agent can be added that encourages chromosomal doubling.
