a is wrong because only plant cells have cell walls
Answer:
angiosperms have flowers that attract organisms like insects, which aid in fertilization. The one evolutionary advantage of angiosperm over gymnosperm is the pressence of flowers. The pressence of flower makes it most successful among other plant group. The pressence of flower in the plant makes plant look more attractive and attracts insects for pollination. This property allows better transportation of flower.The more the insects are attracted towards the plant the transportation of seed will be more. Angiosperms contain both seeds and flowers, while gymnosperms only contain seeds.
Hope this helps!

Given;
W codes for a dominant white phenotype;
w codes for a colored squash;
the Y codes for a dominant yellow phenotype;
the y codes for a recessive green phenotype.
The phenotypes from the first locus mask the phenotype produced by the second locus.
A dihybrid squash, of Ww Yy, is self crossed
WwYy * WwYy
F1 are:
WWYY,WWYy, WWyy, WwYy, Wwyy,wwYy, Wwyy and wwyy etc
Due to dominant epistasis, the progeny are:
White:120
Yellow:30
Green: 10
