How does a mold fossil form?
There are thousands of known species of molds. Like all fungi, molds derive energy not through photosynthesis but from the organic matter in which they live. Typically, molds secrete hydrolytic enzymes, mainly from the hyphal tips. These enzymes degrade complex biopolymers such as starch, cellulose and lignin into simpler substances which can be absorbed by the hyphae. Molds reproduce through small spores, which may contain a single nucleus or be multinucleate. Mold spores can be asexual (the products of mitosis) or sexual (the products of meiosis); many species can produce both types. Mold spores may remain airborne indefinitely, may cling to clothing or fur, or may be able to survive extremes of temperature and pressure.
What is sporolysis?
The definition of sporolysis is the destruction or dissolution of spores. Spores being the beginnings of fungal species, mushrooms, molds, etc...
Who named the cuttlefish?
Ooh, good question. While I doubt anybody could say precisely who named it, the etymology of the word cuttlefish could be interesting. My guess would be that the animal gets its name from the cuttlebone rather than the other way round - cuttlebones can be carved to make molds for metal castings. I reckon they were used by cutlers - people who made knives and forks, cutlery - to produce molds which the cutlery was then cast inside. Anyone else got any ideas?
What do molds produce that kills bacteria?
Since molds don't have an immune system, they produce antibiodics that kill bacteria.
Can mushrooms yeast and molds produce their own food?
yes
What do some molds produce?
Some molds produce allergenic spores or mycotoxins, which can cause allergic reactions or toxic effects in humans and animals. Additionally, certain molds can also break down organic matter, aiding in the decomposition process.
What are called certain molds and soil bacteria produce bacteria killing substances?
antibioitcs
What are two foods that you rely on molds and yeasts to produce?
The the foods are Bread and Beer
What molds produce substances that kill bacteria?
Penicillium and Streptomyces molds produce substances known as penicillin and streptomycin, respectively, which are able to kill bacteria. These substances are used as antibiotics to treat bacterial infections in humans and animals.
Beneficial and harmful aspects of molds?
Molds are necessary in making soy sauce and blue cheeses like Roquefort. A mold called Rhizopus is used to produce the steroid drug cortisone. Molds and other fungi play a critical role as environmental decomposers, working to break down organic materials such as dead trees. Some molds are used in the industrial process because of the chemicals they produce. For example, the mold Aspergillus terreus is used in making plastic.
Which is NOT true of the slime molds?
Slime molds are not true molds as they belong to a separate group of organisms called the Myxomycetes. They are not plants or fungi, but actually belong to the kingdom Protista. Some species of slime molds can move and exhibit a form of simple intelligence in their foraging behavior.

The fruiting bodies in cellular slime molds and sporangia in a cellular slime molds?
The fruiting bodies in cellular slime molds serve as structures for spore formation and dispersal, allowing the organism to reproduce. Sporangia in cellular slime molds are specialized structures that contain spores, which are dispersed to new environments to colonize and continue the life cycle. Both structures are essential for the reproductive success of cellular slime molds.
Why do plants have molds?
Plants have molds because molds depend on them for foods. That's why molds have plants.
