Characteristics of Phylum Angiosperm
| Characteristics of Phylum Angiosperm |
Characteristics of Phylum Angiosperm- Angiosperm is a phylum that found in the classification of plant world. Angiosperm is also called as
flowering plant (the other name). An angiosperm definition is a flowering plant
that produces a seed enclosed by a fruit. The flower function of angiosperm is
to allow the plant to reproduce. Within the flower, the male and female
reproductive parts of an angiosperm is located.
The flower of
angiosperm have many part (organ). The stamen is the part of the flower contains the male
reproductive parts. The pistil is the part of the flower contains the female
reproductive part. In anther (the part of stamen) the pollen produce by the
flower. The pollen that produce by the flower stuck to the stigma. The stigma
is sticky so the pollen can adhere to the female reproductive part.
The ovary is located in
hollow base of the pistil that contains one or more ovules. To be able to
attract the attention of pollinators, the flower have some characteristic like
bright color petals, the smell is usually sweet, and the shape is fools the
male insect. The organism that pollinator for the flowers are bird, insect, and
bat. The relationship between the flower and insect named symbiotic
relationship, because the flower get benefit that the pollen is transferred to
the stigma and the insect get benefit that it’s receives food (nectar) from the
flower. The ovary is also the part of the plant develops into a fruit.
This is the cycle of
angiosperm. 1) The plant produces a flower. 2) Anther produces pollen grains;
Egg is produced in each ovule. 3) The pollen stick to the stigma. 4) The pollen
grows a tube to the ovary; Sperm cell moves down the tube to fertilize egg. 5)
The ovule develops into the seed. 6) The ovary develops into seeds and fruit.
7) The seed grows into a new plant.
The angiosperm divide
by two class, that are monocots (liliopsida) and dicots (magnoliopsida). The
monocot has one cotyledon and dicot has two cotiledon. The monocot leaves has
veins are parallel and the dicot leaves has veins are braching. The monocot
flowers has multiples of three petals on each flower and the dicot flowers has
multiple of four or five petals on aech flower.
The monocot has
vascular tissue scattered throughout the stem, but the dicot has vascular
tissue arrange in ringed bundels. The angiosperm has many benefit like it
produce fruits, vegetables, cereals, beans, rubber, hardwood furniture, cotton
fibers, maple syrup, etc.
