Yes
Why yes, a single celled organism can contain tissue. The Armillaria ostoyae, popularly known as the honey mushroom, is one of the worlds largest living organisms and it is made up of alot of tissue, and is still considered a single cellular organism.
Tissues are made of cells that are all the same type and one cell can't be a tissue.
Not by the definition of tissue. Tissue is a group of specialized cells with a dedicated purpose that usually leads to organs. Unicellular organisms can not have tissue because they would need more than the one cell.
Tissue system
yes
In animals, tissues are made from many specialized eukaryotic cells. Each different type of tissue is made from a slightly different type of cell. Heart is made of cells that have special properties that make them heart cells, the liver is made of liver cells, the skin is made of skin cells, and so on. If you look at cells from different tissues under the microscope, you can see that they look different.
The most basic form of organism is a single-celled microorganism, such as bacteria or archaea. These organisms consist of just one cell that performs all necessary functions for survival.
Multi celled of course! Atoms make up molecules. Molecules make up organelles. Organelles make up cells. cells make up tissue. Tissue makes up organs. organs make up organ systems. Organ systems make up organisms.
No, because remember that there are some one celled organism. That don't even have enough cells to make a tissue
No. Tissues are composed of a variety of cells. A single-celled organism is composed of only one cell. Some unicellular organisms may be colonial, but they do not form true tissues.
Cells make up all organisms, from single-celled to multi-cellular organisms. The order of complexity in a multi-cellular organism is, in order, cell, tissue, organ, system, organism.
A single-celled organism is a living thing made up of only one cell. These organisms can carry out all necessary functions for life within that single cell, including reproduction, metabolism, and responding to stimuli. Examples of single-celled organisms include bacteria, archaea, and protists.
