How did one-celled organisms form?
One-celled organisms are believed to have evolved from simpler molecules in the primitive Earth environment, eventually forming into structures capable of self-replication and metabolism. Over time, these structures evolved into more complex organisms through processes like natural selection and genetic mutations.
Where do you find orgenelles?
Organelles are found within the cells of living organisms. They are specialized structures that perform distinct functions, such as mitochondria for energy production, ribosomes for protein synthesis, and the nucleus for storing genetic material. Both eukaryotic cells (like those in animals and plants) and prokaryotic cells (like bacteria) contain organelles, although prokaryotes have fewer and simpler structures.
Is a beet root prokaryotic or eukaryotic?
Beet root is eukaryotic. It is a part of the plant kingdom, which consists of eukaryotic organisms characterized by complex cells with a nucleus and membrane-bound organelles. Prokaryotic organisms, such as bacteria, lack these features and have simpler cell structures.
Are snails prokaryotic?
No, snails are not prokaryotic; they are eukaryotic organisms. Snails belong to the phylum Mollusca and possess complex cellular structures, including a defined nucleus and membrane-bound organelles. Prokaryotic organisms, such as bacteria, lack these features and have a simpler cellular organization.
Do more-complex organisms always have more chromosomes than simpler organisms do.?
Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
Do more-complex organisms always have more chromosome than simpler organisms do?
Yes
Do more complex organisms always have more chromosome than simpler organisms do?
Yes
What is deference between protozoans and bacteria?
Protozoans are eukaryotic, single-celled organisms with complex cellular structures and can be parasitic or free-living, while bacteria are prokaryotic, single-celled organisms that are much smaller in size compared to protozoans and have simpler cellular structures. Additionally, some bacteria can cause diseases in humans and other organisms, whereas protozoans are generally not known to cause diseases.
Are flowers prokaryote?
No, flowers are not prokaryotes; they are part of the plant kingdom, which consists of eukaryotic organisms. Eukaryotes have complex cells with a nucleus and membrane-bound organelles, unlike prokaryotes, which are simpler and lack a nucleus. Flowers are the reproductive structures of flowering plants (angiosperms), which are eukaryotic organisms.
Are salmon eukaryote or prokaryote?
Salmon are eukaryotes. Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles, which is characteristic of all animals, including fish like salmon. In contrast, prokaryotes are simpler organisms, such as bacteria, that lack a nucleus.
What is a small single celled organisms that do not contain nuclei?
A small single-celled organism that does not contain nuclei is known as a prokaryote. Prokaryotes include bacteria and archaea, which are simpler in structure compared to eukaryotic cells that have a nucleus. These organisms have genetic material that is not enclosed within a membrane-bound nucleus.
Which is simpler a protist or a sponge?
Protist, which are mainly one-celled organisms.
