Angiosperms - First Plants with Flowers

Angiosperms are seed-bearing vascular plants. Their reproductive structures are flowers in which the ovules are enclosed in an ovary. We asked it before.

Characteristics

Angiosperms are able to grow in a variety of habitats. They can grow as trees, shrubs, bushes, herbs, and small flowering plants. Some of the characteristics of angiosperms include:

All angiosperms have flowers at some stage in their life. The flowers serve as the reproductive organs for the plant, providing them a means of exchanging genetic information.
Angiosperms have small pollen grains that spread genetic information from flower to flower. These grains are much smaller than the gametophytes, or reproductive cells, used by non-flowering plants. This small size allows the process of fertilization to occur quicker in the flowers of angiosperms and makes them more efficient at reproducing.
All angiosperms have stamens. Stamens are the reproductive structures found in flowers that produce the pollen grains that carry the male genetic information.
Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.
Angiosperms have carpel that encloses developing seeds that may turn into a fruit.
A great advantage for angiosperms is the production of endosperm. Endosperm is a material that forms after fertilization and serves as a highly nutritional food source for the developing seed and seedling.

Looking Good for the Birds and Bugs

As stated earlier angiosperm has flower and most angosperms species use wind for pollination just like the gymnosperms.

The specialized flowers are able to attract organisms to help pollinate and distribute seeds. Another cool advantage is the fruit/seed packaging. Would you rather eat a pine cone or an apple? A lot of animals would go for the apple. When they do, they are able to spread the seeds across wide areas after the animal poops out the seeds.

Some With One Cotyledon

There are two kinds of seeds in the angiosperms, monocots and dicots . Monocot is short for monocotyledon. A cotyledon is the seed leaf. When you are a monocot, your seed only has one package of food. "Mono" means one or a single cotyledon . Monocots are made up of simple flowering plants like grasses, corn, palm trees, and lilies. Two of the characteristics of monocots are that their flowers have petals in numbers of three and their leaves are made of long strands. Think of the leaves of grass or a palm frond.

And Some with Two

The other kind of plant in the flowering plant world is called a dicot. Dicot is short for dicotyledon. "Di" means two or a double cotyledon. These plants have seeds that have two cotyledons, two seed leaves of food for the embryo. Most of the flowers you see every day are dicots. They have flowers with petals in numbers of four and five. They also have really complex leaves with veins all over, not long like monocots. Some examples of dicots are roses, sunflowers, cacti, apple, and cherry plants.
