Why are angiosperms called flowering plants?
Angiosperms are also known as “flowering plants” because flowers are a characteristic part of their reproductive structure – though again, you may not always recognize their flowers as the pretty, colorful petaled things you think of when you hear the word. Angiosperms evolved between 250-200 million years ago.
How did gymnosperms achieve sexual reproduction?
While gymnosperms relied primarily on the wind to achieve sexual reproduction by transferring pollen – which contain the male reproductive cells for plants – into the ovaries of female plants, angiosperms used sweet-smelling, brightly-colored flowers and sugary nectar to attract insets and other animals.
Why do angiosperms attract animals?
Many angiosperm’s fruits, like their flowers, were designed to attract animals to eat them. In many cases the seeds would then pass safely through the animals’ digestive tracts, getting carried far from the parent plant in the process.
What is the unit of reproduction of a plant?
Seed – A plant’s unit of reproduction, which includes the genetic material and any necessary nutrients to start the development of a new plant.

What are the characteristics of angiosperms?
Angiosperms are the most advanced and beneficial group of plants on the planet. They have diverse characteristics. The characteristics of angiosperms are:#N#1. Occurrence: Angiosperms are found in all environments, up to 6000 m height (from mean sea level). They are found in high temperature, cold deserts, freshwater, saline water, tropical and temperate climates.#N#2. Size: Smallest Angiosperm is Wolffia ( 0.1 m m), and the tallest is Eucalyptus.#N#3. Plant Body: The plant body is sporophytic and diploid.#N#4. Habit: Angiosperms show various habits, like herbs, shrubs, trees, liana, climber, creeper, twinner, etc.#N#5. Life Span: The life span varies to a large extent. Boerhaavia repens of the Sahara desert live for only two weeks, while Lomatia tasmanica has been reported to survive for more than 300 years.#N#6. Roots: They have roots developed from radicles and form tap root systems. In some Angiosperms, adventitious roots are formed from other body parts, like leaves, stems.#N#7. Stems: The first stem develops from plumule. Angiosperms have various modifications of stem, underground, sub-aerial, aerial.#N#8. Leaves: They are for photosynthetic activities and develop from nodes on the stem. Some plants also show a modification in leaves.#N#9. Xylem: In most cases, the Xylem of Angiosperms have vessels, tracheid, xylem parenchyma and xylem fibres (Wood). The Winteraceae have no vessels in their xylem.#N#10. Phloem: In most cases, Phloem of Angiosperms have sieve elements, companion cells, phloem parenchyma, and phloem fibres (Bast).#N#11. Flower: These are the most attractive, complex reproductive structures of Angiosperms. These are most peculiar in Angiosperms only. It is, in most cases, an aggregate of both microsporophylls (stamens) and megasporophylls (carpels). The flower in the plant is a reproductive organ.#N#12. Flowers are modified shoots specialised for reproduction.#N#13. Microsporophyll: It is called the stamen. This has three parts, microsporangium, connective, and filament.#N#14. Megasporophyll: It is called carpel. This has a stigma, style, and ovary that has ovules.#N#15. Pollination: It is unique in Angiosperms as it involves various biotic and abiotic agents for the transfer of pollen from the anther to the stigma of the flower.#N#16. Gametophyte: This stage is highly reduced and represented by cells. Male gametophyte is represented by single cells. The female gametophyte is called an embryo sac which contains female gametes.#N#17. Double fertilization: This is a unique feature that is not present in any other plant group. One of the two male gametes proceeds for syngamy, and the second proceeds for triple fusion and produces primary endosperm nucleus (PEN), which develops into endosperm.#N#18. Endosperm: This is a product of double fertilization which produces triploid tissue for the nourishment of the growing embryo.#N#19. Fruits: They are the ripened and fertilised ovary. They cover the seed. Unlike Gymnosperms, all Angiosperms have covered seeds.#N#20. Seeds: These are the fertilised ovules that are inside the fruit. Seeds develop into a new plant.
Why is angiosperm important?

What are the two classes of angiosperms?
Angiosperms can be classified into two classes: Dicotyledonae and Monocotyledonae.#N# 1. Dicots are those angiosperms that have a pair of leaves or cotyledons present in the embryo of the seed.#N#2. Monocots are the angiosperms that have only one embryonic leaf or cotyledon present in the seed.

What is the purpose of pollination in angiosperms?
2. Pollination is one vital step in the reproduction of Angiosperms, as it brings the male and female gametes together.
What are the structures that make up angiosperms?
Reproduction in angiosperms is mainly sexual. Flowers are considered to play a significant role in the process of reproduction as they contain the reproductive structures called stamen and pistil that produce the haploid male and female gametes.
What are the characteristics of angiosperms?
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: 1 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. 2 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. 3 All angiosperms have stamens. Stamens are the reproductive structures found in flowers that produce the pollen grains that carry the male genetic information. 4 Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly. 5 Angiosperms have carpels that enclose developing seeds that may turn into a fruit. 6 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.

Angiosperms Definition
What are Angiosperms plants? An angiosperm is a flowering plant that produces seeds enclosed in an ovary. Angiosperm comes from the Greek words “Angio” which means a vessel, and “Sperma,” which means seed. They are three broad groups within the plant kingdom, the other two being gymnosperms and cryptogams.
Angiosperm Anatomy
Angiosperms have four primary organs: the root, the stem, the leaves, and the flower.
Angiosperm Flower Anatomy
An angiosperm flower contains four flower parts: sepals (which protect the inner organs during development), petals, stamens, and carpels.
Reproduction in Angiosperms
Angiosperms reproduce in two ways: by self-pollination or cross-pollination.
