Q. Explain about eukaryotic organism or Fungi?
Fungi are eukaryotic organisms. This means that their DNA-containing chromosomes are enclosed within a nucleus inside their cells. (The chromosomes of bacteria and archaea are not walled off inside nuclei, making them prokaryotic organisms). Molds are multicellular, filamentous fungi, which are devoid of chlorophyll. They are larger than yeasts. They are strict aerobes and require oxygen for growth and multiplication and tend to grow more slowly than bacteria.
Fungi are lower thallophytes but do not make their own food via photosynthesis like green plants. They feed on organic matter like rotting leaves, wood, and other debris, or upon the tissues of living plants and animals.
Fungi, along with bacteria, are the planet's major composters and recyclers. Although fungi may seem like a nuisance when they grow in your fruit bowl or refrigerator, their ability to degrade some of the toughest organic materials, including tree wood and insect exoskeletons, means that our planet is not cluttered with a mass of debris. Fungi secrete digestive enzymes in order to break down complex food sources, such as animal corpses and tree stumps, into smaller components they can absorb.
