Kingdom Fungi

Member of the kingdom Fungi include fairly familiar organisms such asmushrooms, toadstools and bracket fungi.

There are also less obvious but veryimportant members such as mold, which grow on bread, ripe fruits and otherfood.

The General and Distinctive Features of the Kingdom Fungi
Explain the general and distinctive features of the kingdom Fungi
General features of kingdom fungi

Fungi are found in damp or wet places

They have eukaryotic cells with a rigid protective wall made of chiti

They are heterotrophs, some are saprophytic where others are parasitic

They store food as glycogen

They reproduce using spore

They are non-mobile

Distinctive features of kingdom fungi

They have chitin in their cell wall

They have septate

The Phyla of the Kingdom Fungi

Ascomycota

Zygomycota

Basidiomycota

Ascomycota
Ascomycota
are also called sae fungi.
They produce spore in sae-like cell
calledasei.
These spores are called ascopores. Examples of Ascomycota
are bakers’yeast, cup fungi and ringworm fungi.
Characteristics of phyla Ascomycota

Their cell wall is not made by chitin but cetin polysaccharide component of phosphoric acid

Have granulated cytoplasm

Store food in form of glycogen

Reproduce asexually by budding and sexually by means of ascospores.

Distinctive features

Reproduce sexually by means of ascospores

The Structure of Mosses
Describe the structure of mosses
Mosses
are small, softplantscalledbryophytes, that are typically 1–10 cm
(0.4–4 in) tall, though some species are much larger.
They commonly grow
close together in clumps or mats in damp or shady locations.
They do
not haveflowersorseeds, and their simple leaves cover the thin wiry
stems.
At certain times mosses produce spore capsules which may appear
as beak-like capsules borne aloft on thin stalks.
Advantage and Disadvantages of Mosses
Outline advantage and disadvantages of Mosses
On
the advantage side, it can help to hold thebonsai soilin place and
prevent it from washing out of the container.
Moss can increase the
water retention capability of the soil by slowingevaporation.
On
the disadvantage side, a thick carpet of moss can reduce the diffusion
of gases into the soil and to theroots, which can result inroot
rotorpoor drainageconditions.

Moss can grow up onto thesurface
