You are reading about a garden designer who has invented something called the "megagarden space" in which a few specimens are planted in a disturbed area and allowed to make a garden by self-propagation. Why might this designer choose to work with angiosperms rather than gymnosperms?
a. Angiosperms can produce flowers and fruits to aid in seed dispersal
b. Angiosperms produce pollen and do not require water to reproduce.
c. Angiosperms have alternation of generations
d. Angiosperms have a vascular system, which allows them to grow taller.

Explanation:

The garden designer chose to work with Angiosperms rather than gymnosperms because:

a. Angiosperms can produce flowers and fruits to aid in seed dispersal

Angiosperms are the only flowering plants. They are considered to be the most evolved groups of plants, because they produce flowers and seeds enclosed in the fruits. Flowers are considered  an advance character because they aid in pollination. seeds enclosed within an fruit is another advance character because the seeds can be protected and dispersed to long distances till they get suitable conditions for germination.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
