During what process do two haploid nuclei within a heterokar

During what process do two haploid nuclei within a heterokaryotic fungal cell fuse? Fertilization Gametogenesis Plasmogamy Karyogamy This process does not occur in fungi Which of the following best describes the role of fungi in an ecosystem? Producers Herbivores Carnivores Decomposers Autotrophs Which of the following statements comparing fungal and animal nutrition is/are correct? Select all correct choices. Fungi and animals are both heterotrophs. Fungi and animals both actively move through the environment in search of food. Fungi digest and then absorb food, whereas animals absorb and then digest food. Fungi are able to break down cellulose, whereas animals can\'t break down cellulose. Fungi and animals both absorb the nutrients that can cross their cell walls. Fungi and animals both ingest their food prior to digestion.

Solution

Q.4 Ans-C plasmogamy

Plasmogamy is life cycle stage in fungi sexual reproduction. During plasmogamy the cytoplasm of the 2[two] parent cells are fuses together without a fusion of the nuclei and effectively bringing 2[two] haploid nuclei near together in same cell, next stage is karyogamy,in this stage two nuclei fudsed together & undergo meiosis, so that they produce spores. dikaryotic state comes after the plasmogamy stage, and dikaryotic stage frequently persist for too many generations,and before fungi undergoes for karyogamy. And lower fungi group plasmogamy is immediately & usually followed by the karyogam

Q.5 Ans-D decomposer

Fungi play important role in ecosystem in several ways, like-Decomposer- is very important to decomposition of plant and animal dead organic matter in ecosystem, by using degradative enzyme to hydrolysis of complex organic matter. It this process Saprophytic fungi play important role, and decomposition necessary for life, Such as oxygen carbon nitrogen cycles. By the breaking-down dead organic matter,the fungi release [oxygen carbon nitrogen ] into soil &a tmosphere.Another role is Mutualistic relationship-for example-Lichen [fungal + algae] algae provide food for fungi by photosynthesis and fungi absorbed essential nutrient to algae for complete mutualistic life of liches. Another fungi also grow in plant root, they absorbed nutrient for plant and in exchange sugars and amino acide fungi take from palnt.

Q.6 Ans

1. correct-Fungi and animals both are heterotrophs because they depend on plant for obtaining nutrient and energy and oxygen for survival.

2. wrong- only animal can move actively not fungi because in fungi they using hyphae or mycelium to reach to food, that’s way fungi is in different category in domain

3.wrong statement-, in animal mode of nutrient is ingestion than digestion than absorb through stomach wall cell, fungi usually decomposition of dead organic matter and digestion and mode of nutrient in fungi are absorption

4.correct- fungi are capable in degrading plant cellulose because they secrete cellulase enzyme to break-down of cellulose into less complex form but in animal can not produce cellulase enzyme to break-down cellulose but ruminant animal use bacterial cellulase enzyme to digest plant cellulose in ruminant animal stomach.

5.wrong- only animal first-ingestion than digestion than absorption by stomach wall cell, but in case of fungi first they break-down or digest than absorb nutrient
