Which of the following correctly describes the spatial arrangement and composition of the cells in a typical mature angiosperm embryo sac, progressing from the micropylar end to the chalazal end?
Options
- AThree antipodal cells One large central cell Two synergids and one egg cell
- BTwo synergids and one egg cell One large central cell Three antipodal cells
- COne synergid and two egg cells One large central cell Three antipodal cells
- DTwo synergids and one egg cell Two distinct central cells Two antipodal cells
Correct answer
B. Two synergids and one egg cell One large central cell Three antipodal cells
Step-by-step solution
A typical mature angiosperm embryo sac is 7 -celled and 8 -nucleate. At the micropylar end, the egg apparatus is present, which consists of two synergids and one egg cell. In the middle, there is one large central cell containing two polar nuclei. At the chalazal end, there are three antipodal cells. Therefore, the correct sequence from the micropylar end to the chalazal end is: Two synergids and one egg cell One large central cell Three antipodal cells. Answer: Two synergids and one egg cell One large central cell
