Why do angiosperms have an advantage?
Those specialized flowers are able to attract organisms to help pollinate and distribute seeds. Another cool advantage is the fruit/seed packaging.
What are the characteristics of Angiospermophyta?
Angiospermophyta
- Has vascularisation.
- Have leaves, roots and stems (individual species may be highly variable in structure)
- Reproduce by seeds produced in ovules within flowers (seeds may develop in fruits)
- Examples include all flowering plants and grasses.
What are Angiospermophyta?
Angiospermophyta (an-ghe-o-sper-MA-fa-ta) is made of three Greek roots that mean a box (angos -ανγοσ); seed (sperma -σπέρμα); and plant (phyto -φυτό). The reference is to the enclosed seeds of the flowering plants.
What features distinguish Coniferophyta and Angiospermophyta?
Members of division coniferophyta have cones and needle- like leaves. They include conifers, pines, cedar and cypress. Division angiospermophyta has two classes namely; monocotyledonae and dicotyledonous. Members of class dicotyledonae have seeds with one cotyledon, tap root systems and leaves with netted venation.
Why angiosperms are more successful than gymnosperms?
Flowering plants are able to survive in a greater variety of habitats than gymnosperms. Flowering plants mature more quickly than gymnosperms, and produce greater numbers of seeds. The woody tissues of angiosperms are also more complex and specialized.
How does Angiospermophyta reproduce?
They have male and female cones for reproduction. Phylum Angiospermophyta are the flowering plants. These plants have roots, stems and leaves, they have xylem vessels to transport water within the stem and phloem to transport sugars. They have seeds produced inside an ovary inside a flower.
What are five important angiosperm families discussed in this chapter?
8.4: Angiosperm Families
- Orchidaceae, the Orchid Family.
- Asteraceae, the Aster Family or Composite Family.
- Fabaceae, the Legume Family.
- Poaceae, the Grass Family.
What are the characteristics of Pteridophytes?
Pteridophyta Characteristics
- Pteridophytes are considered as the first plants to be evolved on land:
- They are cryptogams, seedless and vascular:
- They are cryptogams, seedless and vascular:
- Spores develop in sporangia:
- Sporangia are produced in groups on sporophylls:
- Sex organs are multicellular:
How useful is division Coniferophyta?
Advantages of Conifers They have a large economic use as softwood in furniture. In temperate and tropical regions, they are fast-growing softwoods that will allow harvesting in close succession. Decoration and ceremony Many pine species make attractive ornamentals. They are planted in parks and larger gardens.
What are the characteristics of Filicinophyta?
Filicinophyta (Pterophyta) A phylum of mainly terrestrial vascular plants (see tracheophyte) – the ferns. Ferns are perennial plants bearing large conspicuous leaves (fronds: see megaphyll) usually arising from either a rhizome or a short erect stem.
