How do multicellular organisms begin?
multicellular organisms begin as a single cell.
How are cells in multi-celled organism similar and different in cell in a single cell organism?
Both!All cells in a multicellular organism are identical genetically. This is because they are all formed from a single original cell (in humans, for example, the zygote) by mitosis.However, as the organism develops, some cells will become different in shape and function; this is called differentiation, and it allows different cells to specialize for different roles. Some examples in humans: nerve cells, muscle cells, white blood cells (and there is more than one kind of each of these).
When did the most complex forms of life begin to appear in earth's history?
The most complex forms of life, such as animals, began to appear during the Cambrian period around 541 million years ago. This period is often referred to as the "Cambrian Explosion" due to the rapid diversification and emergence of various complex organisms.
Why is water to living organisms?
with out water you dehydrate and the you begin a small fever then it gets bigger and it can kill you
All living organisms begin the breakdown of their food by?
All living organisms begin the breakdown of their food by digesting it through a process called hydrolysis, which involves breaking down large molecules into simpler ones with the help of water and enzymes. This allows organisms to extract essential nutrients and energy from their food for survival and growth.
How do multicellular organisms begin?
multicellular organisms begin as a single cell.
Do plants and animals begin their lives as multicellular organisms?
yes
Do all organisms begin as a single cell-?
Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
How do all multicellular organisms begin?
Multicellular organisms begin as a single fertilized cell called a zygote. The zygote undergoes repeated rounds of cell division and specialization to form different cell types, ultimately developing into a multicellular organism. This process is known as embryogenesis.
What are some dinosaurs that begin with the letter U?
Ultrasauros dinosaur fossils date from the late Jurassic period. Utahraptor dinosaur lived during the early Cretaceous period.
Are ciliates unicellular or multi cellular?
Protists include unicellular, colonial and multicellular organisms Most protists are unicellular although (only one group) can be multicellular. There are types of algae, green algae known as Ulva, that are multicellular protists. They begin as colonies of unicellular protists known as Volvax, but the ones that break away are the multicellular version. The multicellular protists are without any specialized tissues. Protists used to be considered soley unicellular. Now that the molecular information has been redifined, protists are both unicellular and multicellular. .
When did large numbers of fossils first appear in the geologic record?
Large numbers of fossils begin to appear around 530 million years ago. It is called the Cambrian Explosion, because it occurred in the Cambrian period. The Cambrian period was the first part of the Paleozoic era.
Which Unicellular or multicellular organisms in fresh or salt water begin with A?
Unicellular organism: Amoeba is a common freshwater organism belonging to the phylum Protozoa. Multicellular organism: Algae are a diverse group of aquatic organisms found in both fresh and saltwater environments, serving as an essential component of many ecosystems.
Did birds first begin to fly in the pre-Cambrian period?
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.
What types of organisms have specialized cells?
mutlicellular
When did Mississippian period begin?
At the end of the Wood land period begin
What are some examples for index fossils that begin with the letter T?
trilobites
