Multicellular vs. Unicellular
Which organism is more likely to survive in extreme conditions Unicellular or Multicellular?
Unicellular
What organism has more than one cell, AND more than one cell type.
A Multicellular organism.
Is a Unicellular organism's life span short or long?
Short, they live 12 hours to a few days.
What type of organisms uses organ systems to carry out the many functions of the organism?
Multicellular
Name a example of a multicellular organism.
Any complex organism (human, dog, whale, tree, insects flowers, mushrooms).
True or false? A unicellular organisms can carry out all of the basic functions of life within the one cell.
True
Name the 5 similarities between Unicellular and Multicellular organisms.
1.They are both alive.
2. They both eat and grow.
3. They both get rid of waste.
4. They both contain DNA.
How many Multicellular organisms are needed to reproduce?
2
How do Unicellular organisms reproduce?
Asexually.
You are looking at a specimen under a microscope. How do you decide if you're looking at a Unicellular or a Multicellular organism?
The number of cells that are in the specimen.
What happens to a Multicellular organism when its number of cells increase?
It grows.
Give at least 3 examples of a Unicellular organism.
Bacteria, Paramecium, Amoeba, Yeast.
If you went to a zoo, would there be more Unicellular organisms or Multicellular organisms?
Unicellular....
While a zoo is designed to showcase multicellular animals (mammals, birds, reptiles) and plants, the sheer number of bacteria, archaea, protists, and fungi in the soil, water, air, and inside the digestive tracts of the animals far outnumbers the creatures on display.
Name 3 of the 5 advantages of being a multicellular organism.
1. They have specialized cells for specific tasks.
2. They can grow larger and stronger than Unicellular organisms.
3. They can store nutrients.
4. Damaged cells can be replaced.
5. They can adapt to changes in their environment.
When a Unicellular organism takes in nutrients, what does it do first, grow or divide?
It grows.
After it grows, it divides.
