Notes on the plant kingdom

Pyrenoids store protein and starch. Plant Kingdom Phylogenetic Classification: Pollen grain, after dispersal from the anthers, are carried by wind or various other agencies to the stigma of a pistil. Vegetative reproduction is by fragmentation. The common members are: The synergids and antipodals degenerate after fertilisation.

They are divided into two classes: The mosses have an elaborate mechanism of spore dispersal. On the other extreme, is the type wherein the diploid sporophyte is the dominant, photosynthetic, independent phase of the plant. It stores water in dead cells and creates acid conditions in peat bogs.

Union of gametes may take place in water or within the oogonium oogamous species. They are mainly aquatic organisms and live in freshwater and marine habitats.

It contains pollen grain. The sporophyte, in turn, produces haploid spores by meiosis which grow into another haploid gametophyte. The bryophytes are divided into liverworts and mosses. Anthoceros 3 Phylum Hepaticophyta Liverworts 6, species.

All bryophytes represent this pattern. As against this, natural classification systems developed, which were based on natural affinities among the organisms and consider not only the external features, but also internal features, like ultrastructure, anatomy, embryology and phytochemistry.

These are commonly called red algae. During these events the ovules develop into seeds and the ovaries develop into fruit.

They evolved from bacteria and represent the intermediate step in the evolution of the other three kingdoms. These are the non-vascular plants: The female sex organ called archegonium is flask-shaped and produces a single egg.

Characteristic features- Live in damp and shady habitats, found to grow during rainy season on damp soil, rocks, walls, etc.

CHAPTER 3 – PLANT KINGDOM

Asexual reproduction takes place by biflagellate zoospores. Each stamen consists of a slender filament with an anther at the tip. The plant body has a stalk, stipe and leaf-like fond.

There are 12 phyla in this kingdom, most of which live in water. Below is a list of the 12 phyla which are organized into three groups; plant-like, animal-like and fungi-like. The links are the scientific name, while the common name is in parentheses. At least some parts of a plant are green, thanks to pigment gabrielgoulddesign.comphyll absorbs energy from sunlight for plant to make glucose, using CO2 and H2O from gabrielgoulddesign.com is called photosynthesis.

Plant Kingdom Phylogenetic Classification: At present phylogenetic classification systems are the acceptable system among the scientific community. Phylogenetic systems of classification are based on evolutionary relationship between various organisms.

Chapter 20 : Plant Kingdom

This system is based on the assumption that organisms belonging to the same taxa have a. Chapter Plant Kingdom. Characteristics of the Plant Kingdom: 1) contain chlorophyll a and b 2) store carbohydrate as starch 3) have a cellulose cell wall 4) usually terrestrial (growing on land): waxy cuticle (reduces water loss) stomata in leaf to allow gas exchange.
