Are members of Kingdom Protista prokaryotic or eukaryotic?
The kingdom Protista contains the single-celled eukaryotes in contrast to the bacteria which are examples of the prokaryotic cell type. Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues.
Are protists considered prokaryotes?
All living organisms can be broadly divided into two groups — prokaryotes and eukaryotes — which are distinguished by the relative complexity of their cells. Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes.
Are all prokaryotes are part of the Protista kingdom?
All prokaryotes are part of the Protista kingdom. Mushrooms and yeast belong to the Plantae kingdom. Organisms in the Eubacteria kingdom do not have membrane bound organelles. Most of the organisms in the Animalia kingdom are unicellular.
What one characteristic do all members of the Kingdom Protista share?
Paragraph 3 states, “Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles.” What common trait do all protists share? They are all eukaryotic. They are all photosynthetic.
What do protists and bacteria have in common?
Both bacteria and protists have cell membranes made of chemicals called phospholipids. A phospholipid in a bacterium or a protist has a water-soluble group at one end and a water-insoluble tail at the other, so the cell membranes of bacteria and protists are constructed from a bilayer of phospholipids….
Do protists eat bacteria?
Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter. The animal-like protists must “eat” or ingest food. Some animal-like protists use their “tails” to eat. The protist wraps around its prey, which is usually bacteria.
What do all protists have in common?
What do all protists have in common? They have a nucleus and other complex organelles. They lack some characteristics that prevent them from being classified as plants,animals, or fungi.
What is the difference between a protist and a prokaryote?
Prokaryotes are usually single-celled organisms. They have plasma membrane surrounding the cell but no membrane bound organelles such as the mitochondria, nucleus or Golgi bodies. Protists are all eukaryotes and therefore all have cell organelles, most of them are single-celled but multi-celled form exists.
Why is Protista no longer a kingdom?
Explain why the kingdom Protista is no longer considered a legitimate taxonomic group. Protista polyphyletic: some protists are more closely related to plants, fungi or animals than they are to other protists; it was too diverse, so it no longer a single kingdom.
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 similarities and differences between prokaryotes and eukaryotes?
|Prokaryotic Cell||Eukaryotic cell|
|Nucleus is absent||Nucleus is present|
|Membrane-bound nucleus absent.||Membrane-bound Nucleus is present.|
|One chromosome is present, but not true chromosome plastids||More than one number of chromosomes is present.|
What do both prokaryotic and eukaryotic cells have in common?
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus.
What are some genetic differences between prokaryotic and eukaryotic cells?
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell’s genetic material, while prokaryotic cells don’t have a nucleus and have free-floating genetic material instead….
Is red algae a plant or protist?
Red algae are a very large group of protists making up about 5,000–6,000 species. They are mostly multicellular and live in the ocean. Many red algae are seaweeds and help create coral reefs. Most plant-like protists live in oceans, ponds, or lakes.
Is algae a plant or an animal?
Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Is algae a Heterotroph?
In other words, most algae are autotrophs or more specifically, photoautotrophs (reflecting their use of light energy to generate nutrients). However, there exist certain algal species that need to obtain their nutrition solely from outside sources; that is, they are heterotrophic.
How is algae reproduce?
Algae regenerate by sexual reproduction, involving male and female gametes (sex cells), by asexual reproduction, or by both ways. Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by spores.
How fast does algae multiply?
Microalgae grow fast, and some can double in size in 24 hours. The other type of algae, macroalgae, are more commonly known as seaweed. They are fast-growing marine and freshwater plants that can grow to considerable size.
Do algae have DNA?
The algal cell. The nucleus contains most of the genetic material, or deoxyribonucleic acid (DNA), of the cell. In most algae, the molecules of DNA exist as linear strands that are condensed into obvious chromosomes only at the time of nuclear division (mitosis).
Is algae a cell?
Algae are eukaryotic organisms, which are organisms whose cells contain a nucleus and other structures (organelles) enclosed within membranes. They live in moist environments, mostly aquatic, and contain chlorophyll.
Why are algae green?
Cellular structure. Green algae have chloroplasts that contain chlorophyll a and b, giving them a bright green color, as well as the accessory pigments beta carotene (red-orange) and xanthophylls (yellow) in stacked thylakoids.
