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.

How is a mold fossil formed?
Its a Noun, and here is the definition:A fossil formed when an animal, plant, or other organism dies and is covered by sediment, it flesh decays and bones deteriorate due to chemical reactions, and a cavity remains below the ground surface; the cavity's interior surface is an 'impression in the general form of the original organism's exterior surface.
What forms when a fossil mold is filled?
When a fossil mold is filled, it forms a fossil cast. The cast is a replica of the original organism or object that created the mold, made of the same material as the original organism or object. Fossil casts are valuable in paleontology for studying the morphology of ancient organisms.
What fossil forms an empty space left in a rock?
A fossil mold forms when an organism's remains decay and leave behind an empty space in the rock where it was once located. This empty space can then be filled with minerals to create a fossil cast.
What is cast fossil?
A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.
How are mold and cast related?
The Cast is the fossil of the shell etc itself. The Mould is the hollow left in the surrounding rock if the fossil is removed artificially or by some natural event such as differential dissolution or mass-movement.
How do a fossil mold form?
it hardens and molds the shape
What kind of fossil leaves a body impression?
This is called a trace fossil. or a mold.
What are cast fossils?
One form of fossil forms when an organism dies and its body is covered by layers of sediment. As time passes, the organism itself, particularly when composed primarily of softer materials, is eroded and carried away, leaving a negative imprint of its body. This type of fossil is called a mold. A cast fossil forms when a mold fossil is filled with some form of mineral, usually through the seepage of water depositing the minerals within the mold. In time, the mold is filled and the materials deposited harden, creating a replica of the original fossil. This is called a cast fossil.
Is an animal footprint found is solid rock a mold fossil?
It is a mold fossil
What a mold fossil?
a mold fossil is a fossil formed in a rock by a dissolved organism that leaves an empty space, showing its outward space.
Can a fossil be a mold cast?
no
How can imprints form a fossil?
It takes several millions of years for a fossil to be created. First an animal may step in mud whichs dries over time and becomes hard. After it has that mold the conditions have to be right for it to form. If they are then it will form.
What is a mo fossil?
* A mold fossil is a fossil that is molded onto a rock or mud and other stuff like that considering that the object turns into a mold or fossil it has tofossilize into something wet the drys up into something hard. * A mold fossil could take up to a year to a month to dry up into a mold fossil so will its drying up or already dry it's laying in the ground or water waiting to be discovered you can tell how old a fossil is by looking at the layers so next time you find a mold fossil or any type of fossil look at the layers it has and you will no how old it is or how long its been siting there and that's what a mold fossil is so now you have your answer on what a mold fossil is.
Which forms first a fossil mold or a fossil cast?
First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
What are mold and cast fossils?
A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
How is the mold like the cast?
Mold is like cast in being a type of fossil .
What is a mold and cast fossil?
A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
