1. Two types of food mold, bacteria and fungus.
2. Some are green because that's the color they are, some are blue-ish and some are white like the mold on cheddar. There are also black molds like mildew, and many other colors. Some molds are beneficial like the mold that makes blue cheese. Some are bad, making peaches get green mold before they get ripe.
3. You are feeling the bacterial or fungal growths. There are also slime molds that feel slimy.
4. yeast is a fungus, not a bacteria. It does not have bacterial parts or reproduce like bacteria. Yeast is in the same family as mushrooms.

1. what causes mold?
well mold is actually a microorganism. It grows on surfaces kind of like bacteria does. It reproduces by creating spores and releases them like flowers release pollen. The spores land on a surface and if the environment is right, the spores turn into mold. Most mold like moist environments. Not all molds are green. Some are black, some are red, white,blue, orange just to name some colors. Not all molds feel like a sponge. Some molds are hard, some molds are liquidy. When you eat blue cheese you are eating a mold. (the blue part is mold)
Yeasts are unicelled organisms. They are a special type of fungii with the ability to ferment. Thats how you get beer and yogurt and stuff.

Mold is a type of fungus. It's not always green. You can have blue mold, white mold, black mold, etc. Some of them are even good to eat. (Blue cheese)
Mold feels spongy because it's not a solid mass, but a colony of mold mycelia, which does resemble a sponge when you look at it under magnification.
Yeast is an organizm that's closely related to mold, being a fungus itself.
If you want more detaled information, look up mold and yeast on wikipedia.

Mold is fungus which feeds on stuff like bread and cookies. When the molds reproduce, they release spores and when it land s on bread it grows. It is green as it contains a certain pigment in it which is not chlorophyll. It feels spongy as there is moisture on it. Even its nature is of a spongy type. Yeast is also a microscopic fungi used in making breads. these yeast respire and release co2 in the bread and when it is baked the air gaps make it soft to eat and chew.got ur answer now
