What are two major differences between prokaryotic bacterial and eukaryotic protist cells?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
What are the three most common types of protists?
Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia.
What are 10 protists?
Protist
- Archaeplastida (in part) Rhodophyta (red algae) Glaucophyta.
- SAR. Stramenopiles (brown algae, diatoms, oomycetes.) Alveolata. Apicomplexa. Ciliophora. Dinoflagellata. Rhizaria. Cercozoa. Foraminifera.
- Excavata. Euglenozoa. Percolozoa. Metamonada.
- Amoebozoa.
- Hacrobia.
- Hemimastigophora.
- Apusozoa.
- Opisthokonta (in part) Choanozoa.
Which best describes the offspring of protists?
Asexual binary fission in protists is one major mechanism of reproduction. A single-celled protist’s body is separated into two parts, or halves. After this process, there is no longer a “parental” body, but a pair of offspring. These offspring are called daughter nuclei.
Which characteristic is used to categorize the different kinds of animals like protists?
Like animals, animal-like protists are heterotrophs, and are able to move from place to place to obtain food.
Which best describes the offspring of protists always genetically identical to one parent?
Answer Expert Verified. Protists are the rare and lucky sexual and asexual. asexual always means same, like homologous. because there’s no one else to mate with, so it takes on the exact same genetic material, but sexual reproduction does the opposite.
Are the parents and the offspring identical?
In asexual reproduction all the genes in the offspring come from one parent. In sexual reproduction one full set of the genes come from each parent. Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents.
Why do offspring produced sexually look similar to their parents but not identical?
Answer: In the process of sexual reproduction, haploid gametes produced by the meiotic division fuses to form a diploid zygote. A child inherits half of the genetic material from each parent. So, it may be they look alike but they are not identical to their parents.
Which best explains why it is so difficult to classify protists?
What is an animal-like, unicellular protist called? Why is it difficult to classify protists? There is a lot of diversity between the organisms. They are unicellular.
Why kingdom Protista is considered an artificial grouping?
That is, all plants evolved from one ancestral plant, all animals from one ancestral animal, and all fungi from one ancestral fungus. The protista, however, are not; they are almost certainly polyphyletic and did not arise from a single ancestral protist. Hence, protista is an artificial grouping of organisms.
What are some human diseases caused by protists?
Most protist diseases in humans are caused by protozoa. Protozoa make humans sick when they become human parasites. Trypanosoma protozoa cause Chagas disease and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.
How do protists affect humans?
Some severe diseases of humans are caused by protists, primarily blood parasites. Malaria, trypanosomiasis (e.g., African sleeping sickness), leishmaniasis, toxoplasmosis, and amoebic dysentery are debilitating or fatal afflictions.
What are 3 examples of harmful or pathogenic protists?
We looked at a number of examples, including protists that cause:
- Malaria.
- African sleeping sickness.
- Giardiasis.
- Cryptosporidiosis.
- Trichomoniasis.
- Toxoplasmosis.
- Amoebic dysentery.
