-Yeast produces spores. The mature spores are known as ascospores. Yeast is the most common one-celled fungi. -Molds are Hyphomycetes, which are characterized with having filamentous hyphae, and producing airborne spores.

Taxonomically speaking, microsporidians are fungi, but medically speaking, they are protists. So the answer to your question is… it depends on your definition of fungi. Unicellular fungi are generally referred to as yeasts.

Kingdom Fungi

Yeasts reproduce via budding. Protists undergo either sexual or asexual reproduction. Fungi have cell wall made of chitin, none of the Protists exhibit chitinous wall. Yeasts also perform extra cellular digestion, but not all protists do this.

Although yeast are single-celled organisms, they possess a cellular organization similar to that of higher organisms, including humans. This classifies them as eukaryotic organisms, unlike their single-celled counterparts, bacteria, which do not have a nucleus and are considered prokaryotes.

The genes with the most similarities shared between humans and yeast, are the MSH2 and MLH1 genes.

Yeast is a living organism. Yeast consists of single cells. They are smaller than animal and plant cells, but slightly larger than bacteria. These cells also have several similarities with cells of (green) plants and animals, but lots of differences, which is why they are put into a kingdom of their own.

According to John Palmer one can harvest yeast from the primary and store it in a sanitized jar in the refrigerator for up to a couple of months. The yeast will turn brown as it ages.

Step 1: Mix together equal parts flour and water in a small bowl. Step 3: Twice a day, in the morning and evening, add one to two tablespoons each of flour and water. By doing this, you’re actually feeding the yeast. In about three to five days, your starter will begin to bubble.

Normally bread is made of the ingredients like flour,yeast, water and sugar. Nowadays bread also contain animal products like Egg,milk,casein and gelatin.So, bread cannot be called as a completely vegetarian food.

Strict Jains do not eat root vegetables such as potatoes, onions, roots and tubers as they are considered ananthkay. Ananthkay means one body, but containing infinite lives. Mushrooms, fungi and yeasts are forbidden because they grow in unhygienic environments and may harbour other life forms.

The thinking seems to be that since mushrooms don’t have brains they can’t feel pain so they’re fair game.
