The angiosperm life cycle consists of
sporophyte phase and a gametophyte phase.
typical plant body that one sees when one looks at an angiosperm
sporophyte
e arises when cells of the sporophyte, in preparation for reproduction, undergo miotic division and produce reproductive cells that have only half the number of chromosomes or haploid (n)
gametophyte
full complement of chromosomes
diploid
half complement of chromosomes
haploid
two-celled (two celled) gametophyte called a
pollen grain
An eight-celled eight celled megagametophyte called the(blank) that produces the egg
embryo sac
occurs when the fusion of a sperm and an to produce a zygote which eventually develops into an embryo and after fertilization the ovule develops into a seed and the ovary develops into a fruit.
Fertilization
a broad group of the most primitive flowering plants.
basal angiosperms
They do not belong to either the monocots or eudicots but were for, a long time lumped together with the eudicots into a well-known group called the dicots. T
Basal Angiosperms
number of basal angiosperm species currently existing on Earth that can be separated into two categories:

9000 basal angiosperm species currently existing on Earth that can be separated into two categories
ANITA basal angiosperms
Magnoliids
Basal angiosperms have a number of characteristics that show their primitive evolution
lack any real differentiation between their petal and their sepals
multiple, flattened stamens and multiple carpels, and their fruits are typically single-chambered and dry
less advanced vascular system
Basal angiosperms are found all around the world, with a few exceptions in extreme climates such as
Antarctica and the Saharan desert
A number of the ANITA basal angiosperms are confined within
Australia, Asia and Oceania
majority of the basal angiosperms
Magnoliids
black pepper, avocado, cactus, nutmeg pawpaw and of course the Magnolias.
Magnoliids
e aromatic plants that include several orders in Anita basal angiosperm such as
Magnoliales, Laurales, Piperales. Canellales and Caryophyllales.
are commonly trees are shrubs that produce scented, simple flowers and have dry aggregate fruits
Magnoliales
the most diverse order of Magnoliids and includes aromatic trees or shrubs such as cinnamon and the laurels
