Mobility is not a characteristic of a plant. They are multicellular eukaryotes that have chloroplasts.
Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True
The map of earth has changed over millions of years, but it is now set: False
No fossils from the precambrian era have been found because there were no organisms that time: False
hope these are correct :)
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells.
A. Scientific ideas are changed when better ones are found.
Simple epithelium is a tissue that forms the outer protective layer of the skin of the animal body, it is composed of squamous epithelium cells.
<h3>What is simple epithelium? </h3>
The simple epithelium has only one layer of cells. In this type of tissue, every cell is in direct contact with the basement membrane that is under the cell.
Generally, this type of epithelium is found in the inside areas of the body. This is probably due to its fragile nature. It forms the lining of various body cavities. These are blood and lymph vessels, heart and respiratory system, etc
Because it's a thin layer, it has some physiological advantages as well. These are faster absorption and filtration. This is useful especially when it lines the digestive tract and exchanges surfaces of the lungs.
The simple columnar epithelium is a type of epithelium that has a protective function.
Therefore, it is a tissue that forms the outer protective layer of the skin of the animal body, it is composed of squamous epithelium.
