Fungi are hetrotrophic organisms. They obtain C from other organisms
Fungi are heterotrophic as they lack chlorophyll .
They are fungi.
The group of seedless plants that does not have chlorophyll is fungi. Fungi are heterotrophic organisms that obtain nutrients by breaking down organic matter in their surroundings. They do not photosynthesize like plants, which is why they lack chlorophyll.
Photosynthetic pigments or chlorophyll
Chlorophyll has nothing to do with fungi. Fungi is a type of simple plant that does not have any chlorophyll, which is a green pigment that is used in photosynthesis.
Mushrooms and other fungi
They are plant-like heterotrophs(don't produce their own food) that lack chlorophyll. They are decomposers.
Yes. I don't know the full extent of plants without chlorophyll, but one example is the Indian pipe (http://en.wikipedia.org/wiki/Monotropa_uniflora). I'd be surprised if there weren't others.
A multicellular organism with cell walls but no chlorophyll would be classified as a fungi. Fungi are eukaryotic organisms that obtain nutrients through absorption, and their cell walls are made of chitin or other substances. They do not perform photosynthesis as they lack chlorophyll.
Plants cells contain chloroplasts, allowing them to make their own food through photosynthesis. Fungi do not have chloroplasts. The cell walls of plants are made up of cellulose while the cell walls of fungi are made up of chitin. Those are only a few of the many differences between plants and fungi.
All animals lack chlorophyll and also several plants like croton or ornamental plants and also fungi and other saprophytes( who depend on dead organic matter for food).
Fungi have no chlorophyll.
