true or false if false correct statement fungi do not contain chlorophyll
if anyone tell me correct answer I would make u as brainlist​

Answer 1

Answer:

$\pink{✧</p><p>ANSWER✧</p><p>}$

$\sf \:True$

$\pink{REASON}$

Fungi do not have chlorophyll in their cells. Therefore they cannot produce food and must depend upon other living or dead things for food. They are heterotrophic and can be classified as saprophytes, parasites, symbionts.

They live as saprophytes getting their nourishment from the surroundings and play key role in nature by decomposing dead organisms and releasing their nutrients for reuse by the living. Some live in a mutually beneficial symbiotic relationship with another organism, often a plant. The association of fungus and plant root is called a mycorrhiza.

Some fungi are parasitic, causing serious damage to their host.

✯What is Fungi?

Fungi are eukaryotic organisms that include microorganisms such as yeasts, moulds and mushrooms. These organisms are classified under kingdom fungi.

The organisms found in Kingdom fungi contain a cell wall and are omnipresent. They are classified as heterotrophs among the living organisms.

✯Structure of Fungi

The structure of fungi can be explained in the following points:

• Almost all the fungi have a filamentous structure except the yeast cells.

• They can be either single-celled or multicellular organism.

• Fungi consist of long thread-like structures known as hyphae. These hyphae together form a mesh-like structure called mycelium.

• Fungi possess a cell wall which is made up of chitin and polysaccharides.

• The cell wall comprises protoplast which is differentiated into other cell parts such as cell membrane, cytoplasm, cell organelles and nuclei.

• The nucleus is dense, clear, with chromatin threads. The nucleus is surrounded by a nuclear membrane.

✯Characteristics of Fungi

Following are the important characteristics of fungi:

• Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.

• They may be unicellular or filamentous.

• They reproduce by means of spores.

• Fungi exhibit the phenomenon of alternation of generation.

• Fungi lack chlorophyll and hence cannot perform photosynthesis.

• Fungi store their food in the form of starch.

• Biosynthesis of chitin occurs in fungi.

• The nuclei of the fungi are very small.

• The fungi have no embryonic stage. They develop from the spores.

• infect the host.

• Fungi produce a chemical called pheromone

• Examples include mushrooms, moulds, yeast.

✯Classification of Fungi

Kingdom Fungi are classified based on different modes. The different classification of fungi is as follows:

☆Based on Mode of nutrition

On the basis of nutrition, kingdom fungi can be classified into 3 groups.

• Saprophytic – The fungi obtain their nutrition by feeding on dead organic substances. Examples: Rhizopus, Penicillium and Aspergillus.

• Parasitic – The fungi obtain their nutrition by living on other living organisms (plants or animals) and absorb nutrients from their host. Examples: Taphrina and Puccinia.

• Symbiotic – These fungi live by having an interdependent relationship association with other species in which both are mutually benefited. Examples: Lichens and mycorrhiza. Lichens are the symbiotic association between algae and fungi. Here both algae and fungi are mutually benefited as fungi provide shelter for algae and in reverse algae synthesis carbohydrates for fungi.

☆Based on Spore Formation

Kingdom Fungi are classified into the following based on the formation of spores:

• Zygomycetes – These are formed by the fusion of two different cells. The sexual spores are known as zygospores while the asexual spores are known as sporangiospores. The hyphae are without the septa.

• Ascomycetes – They are also called as sac fungi. They can be coprophilous, decomposers, parasitic or saprophytic. The sexual spores are called ascospores. Asexual reproduction occurs by conidiospores. Example – Saccharomyces

• Basidiomycetes – Mushrooms are the most commonly found basidiomycetes and mostly live as parasites. Sexual reproduction occurs by basidiospores. Asexual reproduction occurs by conidia, budding or fragmentation. Example- Agaricus

• Deuteromycetes – They are otherwise called imperfect fungi as they do not follow the regular reproduction cycle as the other fungi. They do not reproduce sexually. Asexual reproduction occurs by conidia. Example – Trichoderma.

✯Reproduction in Fungi

Reproduction in fungi is both by sexual and asexual means. The sexual mode of reproduction is referred to as teleomorph and the asexual mode of reproduction is referred to as anamorph.

• Vegetative reproduction – By budding, fission and fragmentation

• Asexual reproduction – This takes place with the help of spores called conidia or zoospores or sporangiospores

• Sexual reproduction – ascospores, basidiospores, and oospores

Answer 2

Answer:

Fungi do not contain chlorophyll. The given statement is correct.

Explanation:

Fungi is a eukaryotic organism which is classified as a individual kingdom. Fungi are heterotrophs, therefore they depend upon other organisms for food. They do not perform photosynthesis process due to the absence of chlorophyll in them.

Chlorophyll is basic requirement in converting the light energy to chemical energy via photosynthesis process.

• Fungi contributes in the decomposition of the organic matter. So, they provide nutrients back to the soil.

• Fungi consists spores for the process of asexual reproduction.
• In fungi, sexual reproduction process occurs through meiosis.
• In fungi for the process of reproduction. the bud is formed by budding.
