Title: Angiosperms Phylum Anthophyta


1
AngiospermsPhylum Anthophyta
  • Largest group of plants

2
Angiosperms are flowering plants.
  • They have true roots, stems, leaves and
    flowers...
  • Angiosperms are more highly evolved that the
    algae, mosses, fungi and ferns. Their advanced
    structures allow angiosperms to thrive on land.

3
Angiosperm
  • Angeion vessel or carpal
  • Sperma seed
  • The carpal which contains the ovule that develop
    into seeds after fertilization
  • The carpal itself develops into the fruit wall.

4
Angiosperms are the biggest group in the plant
kingdom.And very diverse!

Angiosperm
  • They have roots that hold the plant in place and
    take in needed minerals and water. They have
    leaves that are the major food makes for the
    plant. They have stems that hold the plants up
    and move the nutrients and water about the plant.

7
  • They also have seeds.The seeds are formed when an
    egg or ovule is fertilized by pollen in the
    ovary. The ovary is within a flower. The flower
    contains the male and/or female parts of the
    plant. Fruits are frequently produced from these
    ripened ovaries.

Angiosperm benefits
  • Angiosperms the primary food source for animals-
    grains, beans, nuts, fruits, vegetables, herbs
    and spices almost all come from plants with
    flowers, as do tea, coffee, chocolate, wine,
    beer, tequila, and cola.
  • They provide lumber for buildings and other
    objects, fibers for clothes, are the basis for
    many drugs, etc
  • provides oxygen for us to breathe.

10
Compare to other seed plants
  • Like other seed plants, angiosperms are
    heterosporangiate-producing pollen and ovules in
    different organs.
  • Unlike most seed plants, however, the pollen and
    ovule-bearing organs are usually produced
    together in a bisporangiate strobilus called a
    flower.

11
The flower
  • In the center of a typical flower are the
    carpels, modified leaves which enclose the
    ovules. These are often fused to form a single
    pistil in the center of the flower.
  • Surrounding the carpels are several narrow stalks
    topped by pollen sacs these pollen-bearing
    stalks are called stamens.
  • Around these reproductive organs is the perianth,
    usually consisting of an outer whorl of sepals
    and an inner whorl of petals.

Collectively Sepals form the calyx Petals form
the corolla Both form perianth
15
Contains microsporangia
16
  • In monocots and "primitive" dicots, the sepals
    and petals may be indistinguishable, in this case
    the perianth parts are called tepals.

17
Angiosperm
  • Monophyletic
  • Include two large classes
  • Monocotyledones (monocots)
  • Grasses, lilies, irises, orchids, cattails, and
    palms
  • Eudicotyledones (eudicots)
  • Almost all familiar trees, and shrubs other than
    the conifers and many nonwoody plants (herbs).

Eudicots
  • Saguaro cactus
  • Thick fleshy stem store water
  • Contain chloroplast
  • Taken over photosynthetic function
  • Round lobed hepatica
  • Flower on deciduous woodlands
  • No petals
  • 6-10 sepals
  • Numerous spirally arranged stamens and carpels
  • California poppy

Most are free living but some are Parasitic
  • Dodder (Cuscuta salina)
  • Member of the morning glory family
  • Rafflesia arnoldii
  • Parasitic on the roots of a member of the grape
    family

Some Angiosperm are Saprophytic
Indian pipe (Monotropa uniflora)
29
Inflorescences
  • In many angiosperms, the flowers are arranged in
    clusters called inflorescences.
  • The flowers may be attached along a tall stalk,
    arranged in broad open clusters, or pressed
    tightly together so that the cluster looks like a
    single flower.
