All Fungi do not have chlorophyll. What characteristic makes them like so?
GENERAL CHARACTERISTICS OF FUNGI
As __________, fungi digest dead animal and plant materials
GENERAL CHARACTERISTICS OF FUNGI
As parasites of plants or animals, fungi use the same mode of nutrition but they take up nutrients from the living cells of the plants and the animals they invade
MORPHOLOGY OF FUNGI
It is the tubular filament that exhibit apical (apex/tip) growth for fungi.
MORPHOLOGY OF FUNGI
A mass of hyphae/collection of hyphae
MORPHOLOGY OF FUNGI
It is the body/soma of fungi.
TYPES OF HYPHAE
Based on Septation
TYPES OF HYPHAE
Based on Function
OTHER STRUCTURES OF FUNGI
It is the outgrowth of somatic hypha in parasitic fungi. (Branch that grows elsewhere; for parasitic fungi only)
OTHER STRUCTURES OF FUNGI
Root-like structures of fungi
OTHER STRUCTURES OF FUNGI
Hypha that connects two rhizoids
OTHER STRUCTURES OF FUNGI
Formed by the nematode-trapping fungi (hyphae which are adapted for trapping/killing preys)
NUTRITION OF FUNGI
They are chemoheterotrophic (both E and C are from organic compounds)
NUTRITION OF FUNGI
Fungi are non-absorptive
NUTRITION OF FUNGI
The mode of nutrition of fungi can either be:
saprophytic (organisms feeding on dead or decaying organic matter in which hyphal tips release enzymes that cause enzymatic breakdown of substrate & products are absorbed back into the hyphae) OR ________
Nutrition of fungi wherein the products of enzymatic breakdown of substrate are absorbed back into the hyphae. To initiate enzymatic breakdown of substrate, the enzymes are released from the hyphal tips. Organisms feed on dead organic matter.
NUTRITION OF FUNGI
Growth Requirements
The carbon source of fungi (either 2)
NUTRITION OF FUNGI
Growth Requirements
Nitrogen Source of fungi are either organic or inorganic
NUTRITION OF FUNGI
Growth Requirements
Most fungi grow at 0 to 35 degrees Celsius, but the optimal temperature for their growth is approximately...
NUTRITION OF FUNGI
Growth Requirements
Optimal pH for Fungi
ENVIRONMENTAL INTERACTIONS OF FUNGI
Many fungi form symbiotic relationships with this eukaryotic kingdom
The association between fungi and algae or cyanobacteria in which these are used as biomonitors of atmospheric quality,
In the symbiotic relationship for lichens, which is the mycobiont and which is the photobiont?
What are the 6 Growth forms of lichens?
LICHEN GROWTH FORMS
A crusty Lichen on a rock
LICHEN GROWTH FORMS
Leafy lichen on a branch of a tree
LICHEN GROWTH FORMS
Wolf Lichen, Letharia vulpina. Grows like a multiple-branched tuft or leafless mini-shrub
what is the wolf lichen of fruticose?
LICHEN GROWTH FORMS
Caloplaca thallincola. Grows like a crust, and in a pattern that radiates outward from the center, so it has this growth form
LICHEN GROWTH FORMS
Lepraria incana. Grows like powder dusted on the rock.
what is the species of leprose lichen?
LICHEN GROWTH FORMS
Collema nigrescens. Without internalstructure for its parts.
Gelatinous lichen species
USES OF LICHENS
It is a source of food. Examples:
Wila (Bryoria fremontii) in North America
Iceland Moss (Cetraria islandica) in Northern Europe
Umbilicaria esculenta which is a traditional Korean and Japanese Food
USES OF LICHENS
To determine the age of exposed rock surfaces based on the size of the lichen thalli.
USES OF LICHENS
To degrade polyester resins and accumulate lead and copper.
USES OF LICHENS
Lichens can be used for the production of dyes which are utilized as antibiotics and indicators of __.
USES OF LICHENS
Acid that is used for the suppression of tuberculosis; bioactive compound mainly found as a secondary metabolite in lichens.
USES OF LICHENS
Lichens are also used for aesthetic appeal
A unique fungi genera that has the association between plant roots and fungi. The presence of this fungi makes it so that the roots of plants are longer.
MODE OF REPRODUCTION OF FUNGI
Type of reproduction of fungi that is more important for propagation of fungal species
MODE OF REPRODUCTION OF FUNGI
Asexual Reproduction is important for propagation of species because of the following except for:
MODE OF REPRODUCTION OF FUNGI
Methods of Asexual Reproduction
The hyphae break up into their component cells that behave as spores called arthrospores.
What do you call the broken hyphae which are spores from fragmentation?
MODE OF REPRODUCTION OF FUNGI
Methods of Asexual Reproduction
The simple splitting of a cell into 2 daughter cells by constriction and formation of a cell wall.
MODE OF REPRODUCTION OF FUNGI
Methods of Asexual Reproduction
The production of a small outgrowth from a parent cell

Methods of Asexual Reproduction
Most common method of asexual reproduction of fungi. It varies in color, size, shape, number, arrangement of cells, and manner by which they are borne.
Major Types of Asexual Spores
Asexual Spores Types Based on Spore Development:
Developed by septation and fragmentation. At the tip of hypha (as arthrospores) or either intercalary (as chlamydospores)
Asexual Spores Types Based on Spore Development:
Developed by budding and swelling. Single spores or chain of spores (e.g. blastospores or phialospores)
