The molecular data indicate the seed plants most closely related to the angiosperms are the gnetophytes and bennettitaleans, which, incidentally, is the same conclusion reached by some botanists using morphological and anatomical features 50 years ago. Haploid spores nwhich are produced by meiosis, are tiny and easily carried by wind and water; seeds, which contain a diploid sporophyte embryo 2n and its initial nutrient supply, are comparatively large; both spores and seeds are resistant to extremes of the plant’s environment, e.

Phylum Anthophyta—The Flowering Plants

What is the first generation produced in mosses? Chemical compounds produced by plants are either: There are more questions than answers in the phylogeny of the angiosperms. Angiosperms have stems; what are the two functions of stems?

When a bug lands on the hairs, the trap snaps shut and digestive juices digest the bug. Where do ferns grow best?

Fruits can be dry or fleshy, remain closed or split open at maturity, have hooks or divisioj that attach to fur or feathers.

Cladists in general favor a woody origin, but there are equally vociferous advocates for the herb hypothesis. Examine a dicot seed such as a peanut.

List two examples of this type of coevolution. These complex structures are produced by the sporophyte plants.

The endosperm is a nutrient tissue within the seed it is most of what you eat in corn. Within this is a special, triploid 3n nutrient tissue called endosperm that was formed by a separate divisioon from that of the egg.

The monocots are a monophyletic group with a common ancestor based on their single cotyledon and a few other features. Initially each contains a big, diploid megaspore mother cell in a chamber called the megasporangium. A Synopsis of the Living World Classification: One of the advantage that angiosperms hold against gymnosperms is their reproduction.

Some kinds of seeds are unable to germinate until the seed coat has been eroded by passage through an animal’s digestive system. Bamboos are in the same family ass grass, and thus marks them as monocts. These plants can include Roses to Daffodils and even Mango trees. Fill in the missing information for the chart below.

Where is the pollen left on angiosperms? The seeds of fruit that is eaten get free transportation dispersal and are deposited in a rich packet of fertilizer.

Phenolics are imporant secondary metabolites whose plant roles are still being discovered. Some, such as pitcher plants, are even insectivorous. Fertilization by the two sperm cells from the pollen is double.

Oak tree’s are dicots because they have netted vein structure s on their leaves have clustered vascular tissue. Also called Angiosperms, are common flowering plants that may produce fruit. The Anthophyta are divided into two major groups: What structure encases the fertilized egg cell? What group of gymnosperms has only one surviving species? In what type of environments are gymnosperms more successful than angiosperms?

The sporophyte consists of plumule embryonic leaveshypocotyl embryonic stemand radicle embryonic root.

Alkaloids produced as secondary metabolites include: Different types of plants have different characteristics. In advanced flowers, the carpel is folded inward and the seeds are enclosed.

Peace Lily’s have netted veins and clustered vascular tissue. The other sperm enters the central cell and the resulting polyploid tissue is called endosperm. Perennials though, persistx for many growing seasons without dying. Insects, frogs, and other small creatures are attracted to the nectar and bright colors on the pitchers and anthpohyta.

What are fern leaves called? Why are mosses usually restricted to moist habitats?
