It is also more complex than aesxual reproduction and thus requires a more detailed description to establish an understanding of how the process differs between Protists and Fungi. During Fungal sexual reproduction the nuclear membrane and the nucleolus usually remains intact throughout the entire process [9].
Plasmogamy, karyogamy and meiosis comprise the three sequential stages of fungal sexual reproduction [9]. Plasmogamy entails protoplasmic fusion between the mating cells which brings the distinct haploid nuclei into the same cell [9]. The fusion of these haploid nuclei and formation of a diploid nucleus occurs in the karyogamy stage [9]. Near the end of karyogamy a zygote exists and meiosis proceeds by the formation of spindle fibers within the nucleus.
This reestablishes the haploid state via diploid chromosome separation [9]. Fungal strategies for haploid nuclei interaction during sexual reproduction are more varied in Fungi compared to Protists. These strategies include gamete formation and release from gametangia sex organs , gametangia interaction between two organisms and somatic hyphae interaction [9]. Protist sexual reproduction strategies are nearly entirely dissimilar to those employed by Fungi.
These strategies entail unique processes that differ as a result of the cellular structure, particularly cellular appendages available for contact with other Protists [8]. Gamete formation and release is a sexual reproductive method among the highly motile flagellated protists [8].
Conjugation is a method used by ciliated Protists which entails the fusion of gametic nuclei rather than the formation and release of independent gametes [8].
Autogamy, a process of self-fertilization that is still considered a form of sexual reproduction, produces homozygosity among the progeny of a self-fertilized parent cell [8]. As summarized above, the differences between Protists and Fungi are vast and can be observed at every level of structure and throughout all of their behavioral interactions with their environments. This review is merely a summary of differences. The references cited provide more in-depth explanations for those interested in learning more.

Cell Membrane Protists can contain plant-like cell walls, animal-like cell walls and even pellicles providing protection from the external environment [3]. Intracellular Organization Fungi are comprised of convoluted system of hyphae compartmentalized by a partitioning system of septa [1]. Cellular Appendages Unlike the mostly stationary Fungi, protists are motile [1,3] and this motility differentiates Protists morphologically from fungi by the addition of cellular appendages.
Respiration Protist Respiration i Protist Aerobic Respiration Protists obtain oxygen by diffusion and this limits their capacity for cellular growth [3].
Somatic cells in yeast form buds. All mushrooms are fungi , but not all fungi are mushrooms. For those fungi that produce them, the mushroom plays a similar role to a flower or a fruit in plants. Some part of each mature mushroom produces microscopic spores that are similar to pollen or seeds, sometimes numbering in the trillions [1].
Fungi are heterotrophic - they obtain their organic material from external sources, their environment. They have no chlorophyll; they are not green in color.
In comparison, most plants are autotrophic, they are able to manufacture their food from solar radiation and water. The primary difference between them is their cellular organization. Bacteria are single-celled microbes and are prokaryotes, which means they're single-celled organisms lacking specialized organelles. In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi , or animals.
Asexual reproduction is the most common among protists. Protists can reproduce asexually through binary fission, one nucleus divides; multiple fission, many nuclei divide; and budding. Budding occurs when a new organism grows from the body of its parent. They can, however, also reproduce by sexual reproduction. What do Fungi and Animals have in Common? Both fungi and animals are without chlorophyll. Both are having heterotrophic mode of nutrition not self synthesizers like plants In both, the cells are eukaryotic with organelles like mitochondrion, ER, Golgi etc.
Both store carbohydrate as glycogen reserve food. The most important difference between plants and fungi is that plants can make their own food, while fungi cannot. As you know, plants use carbon dioxide, sunlight and water to create their own food.
This process is known as photosynthesis. Fungi , on the other hand are incapable of making their own food. The most obvious similarity between fungi and animals is their trophic level, that is, their place in the food chain. Neither fungi nor animals are producers as plants are. Both must use external food sources for energy. Fungi and animals share a molecule called chitin that is not found in plants.
Seeds are absent Reproduction takes place through seeds They have filamentous bodies made of long slender filaments woven together to form the fungus reproductive structures They have a variety of cell and tissue types. General Characteristics of Fungi: Eukaryotic. Decomposers — the best recyclers around. No chlorophyll — non photosynthetic. Glomeromycota are parasites in plants. They invade roots of plants by their fungal hyphae. Basidiomycota produce meiospores in basidia.
Chytridiomycota, Neocallimastigomycota and Blastocladiomycota produce zoospores, which are mobile. Figure 2: Sarcoscypha occidentalis fruit bodies. Protists: Some protists like molds and algae have a cell wall. But, others do not have a cell wall like protozoans.
Fungi: Fungi contain a cell wall made up of chitin. Protists: Protists are either autotrophs, heterotrophs, parasites or saprotrophs. Protists: Asexual reproduction is observed in protists through binary fission. Sexual reproduction occurs viathe production of gametes. Fungi: Asexual reproduction occurs by producing spores. Fungi: Septa are found in fungi, separating fungal hyphae into compartments.
Protists: Protozoans, algae and molds are the three types of protists. Fungi: Microsporidia, Ascomycota, Glomeromycota, Basidiomycota, Chytridiomycota, Neocallimastigomycota and Blastocladiomycota are the seven phyla of fungi.
Protists: Green algae, slime molds, euglena and amoeba are the examples of protists. Fungi: Yeast, Pichia, Basidiomycota and Eomycota are the examples of fungi. Protista and fungi are lower level organisms, which are classified into the kingdom Protista and Fungi, respectively. Protists are mostly unicellular organisms, whereas the fungi are mostly multicellular organisms. Protozoans, algae and molds are the three types of protists. Protozoans are animal-like, engulfing food particles from the environment by phagocytosis.
Algae contain chloroplasts. Molds are fungus-like giant structures. Protists can be either heterotrophs or autotrophs.
