Why are protists disgusting groups such as animal-like plant-like and fungus-like protists?
Protists are often considered "disgusting" due to their diverse and sometimes peculiar characteristics, which can include slimy textures, unusual shapes, and the presence of harmful pathogens. Animal-like protists, like amoebas, can exhibit behaviors that resemble parasites, while some plant-like protists, such as algae, can bloom excessively, resulting in harmful algal blooms. Fungus-like protists, such as slime molds, can appear decayed or mushy, further contributing to their unappealing reputation. Overall, their varied forms and functions can evoke a sense of discomfort or disgust in many people.
What are true statements of the kingdom Protista?
Protists are eukaryotic organisms that do not fit into the plant, animal, or fungal kingdoms. They exhibit a wide range of diversity in terms of size, shape, and habitat. Many protists are unicellular, but there are also multicellular protists like algae.
Which kingdoms organism have no cell walls?
Animal cells do not have cell walls. Many animal-like protists also lack cell walls.
How are protists like both plants and animals?
All animal-like protists are heterotrophs (can not make their own food) and are able to move in their environment in order to find their food. Animal-like protists are all unicellular. Plant-like protists are autotrophic (make their own food like plants). Many are unicellular (single cells) but some are many cells.
Discuss how protists are categorized Why are these categories debatable and how might analyzing the DNA change the classification system?
Protists are categorized into one of the following three groups: Plant like, Animal like and Fungus like. It is debatable because they are group based on any common features rather than on how they have evolved over the years.
Is animal like protists a decomposer?
Yes, some animal-like protists can act as decomposers by breaking down organic matter to obtain nutrients. These protists play a crucial role in nutrient recycling in ecosystems by recycling organic material into simpler compounds that can be used by other organisms.
Is plankton a protists?
Yes, plankton can include protists. Protists are a group of diverse eukaryotic organisms that do not fit into the plant, animal, or fungi kingdoms, and many species of plankton fall under this category.
Can protists move from place to place?
Yes, many protists have structures like flagella, cilia, or pseudopods that allow them to move from place to place. This movement helps protists find food, avoid predators, and locate optimal environmental conditions.
Why is the kingdom protista difficult to classify what is the basis of their grouping in kingdom protista Give examples of each of its groups?
The kingdom Protista is difficult to classify due to the vast diversity of organisms it includes, which are not closely related and can exhibit both plant-like and animal-like characteristics. Protists are typically grouped based on their nutritional modes and cellular structures, leading to classifications such as protozoa (animal-like), algae (plant-like), and slime molds (fungus-like). For example, amoebas represent protozoa, diatoms are a type of algae, and slime molds like Physarum polycephalum exemplify the fungus-like protists. This diversity complicates a clear taxonomic structure, as many protists do not fit neatly into traditional categories.
Do a live plant or animal may be made of only one cell?
Part of the definition of both the plant and animal kingdom is multicellularity. Technically, no plant or animal under the current definition can be unicellular. However, the protist kingdom contains one-celled organisms with plant or animal characteristics. In fact, animal-like protists and plant-like protists used to be referred to as animals or plants. Many types of green algae are single-celled, as are amoeba and paramecia.
What are the phyla of animal like protists that have only free living members?
The phyla of animal-like protists that consist solely of free-living members include Ciliophora (ciliates), which are characterized by their hair-like structures called cilia used for movement and feeding, and Euglenozoa, which includes euglenids that often have flagella for locomotion. Other examples include the Amoebozoa, particularly those with free-living amoebas that move and feed using pseudopodia. In contrast, many other protist groups may include both free-living and parasitic species.
What protists move by means of many short-hair like projections?
Ciliates are protists that move by the means of many short hair-like projections, called cilia.
