Please HELP ! :(

Biology
1 answer:
Degger [83]3 years ago
5 0

Cells are small because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume.

Hope this helps!

Which shows the correct order of processes for fungi to reproduce sexually? a fungus that is genetically identical to the parent
slavikrds [6]

The right order for the fungi to reproduce sexually is:

<u>hyphae exchange genetic material, a spore forms, and the spore grows into a genetically unique fungus.</u>

<h3>What is fungus?</h3>
  • Any member of the eukaryotic group of organisms, which also includes the more well-known mushrooms and microbes like yeast and mold, is referred to as a fungus.
  • Some of the examples for Fungi are rusts, yeasts, molds, stinkhorns, truffles, mushrooms
<h3>Where can you find fungi?</h3>
  • Fungi can be incredibly sophisticated multicellular organisms or single-celled critters.
  • They can be found in almost any location, but the majority of them prefer to dwell on land, primarily in soil or on plant matter, as opposed to the sea or fresh water.
<h3>Reproduction in Fungus:</h3>
  • Most fungi have sexual and asexual reproduction abilities.
  • This enables them to adapt to environmental changes.
  • When the environment is stable, they can spread swiftly through asexual reproduction.
<h3>Asexual reproduction in fungi:</h3><h3>fragmentation </h3>
  • Hyphae fragments can sprout new colonies.
  • A fungal mycelium fragments as it splits into pieces, with each piece developing into a new mycelium.
<h3>budding</h3>
  • Most yeasts and some filamentous fungi engage in budding, which is an additional asexual reproduction strategy.
  • This process results in the development of a bud, whose cytoplasm is continuous with that of the parent cell, on the surface of either the yeast cell or the hypha.
<h3>producing spores.</h3>
  • The majority of fungi reproduce by producing spores, which can endure harsh conditions including extreme cold and a lack of water.
  • Depending on the species and environmental factors, asexual and sexual meiotic spores can both be formed during mitosis.
  • A diploid and haploid stage coexist in the majority of fungi's life cycles.
<h3>Sexual reproduction in fungi:</h3>

Plasmogamy, karyogamy, and meiosis are the three successive steps of sexual reproduction in fungi.

<h3>Plasmogamy:</h3>

Plasmogamy unites two compatible haploid nuclei by joining two protoplasts, or the contents of two cells.

<h3>Karyogamy: </h3>
  • These haploid nuclei fuse together during karyogamy to form a diploid nucleus (i.e., a nucleus containing two sets of chromosomes, one from each parent).
  • The zygote is the name for the cell created during karyogamy.
  • In the majority of fungus, the sole diploid cell throughout the whole life cycle is the zygote.
<h3>Meiosis:</h3>
  • Meiosis (reduced division) starts the haploid phase, which generates the gametes, and restores the haploid amount of chromosomes.
  • With the exception of the zygote, all structures in the bulk of fungi are haploid.
  • At the time of zygote formation, nuclear fusion occurs, and meiosis immediately follows.
