Dutch tradesman and scientist, Antoine Philips Van Leeuwenhoek is considered by many to be the Father of Microbiology, and the first scientist to ever see a unicellular life form through a microscope. His discoveries helped develop the microscope and lay the foundations for the modern science of microbiology.
Anton Philips van Leeuwenhoek (in Dutch also Anthonie, Antoni or Theunis, in English Antony or Anton) [1] (born on October 24, 1632 -- baptized on November 4, and buried on August 30, 1723) was a Dutch tradesman and scientist from Delft, the Netherlands. He is commonly known as "the Father of Microbiology", and considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes he was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries (small blood vessels). Van Leeuwenhoek never wrote a book, just letters.

The microscope
Organism that have one cell (single celled) are so small, you would need a microscope to see them. So, orchids are multicellular.
Yes. One celled or unicellular organisms are so small you would need a strong microscope to see one.
one-celled organisms like amoebas don't "see" they detect changes in their environment
Microscopes
A one celled organism is something you see in a microscope like a virus. A bald eagle is a many celled organism.

Anything that you can see (and is alive).
Yes. One celled or unicellular organisms are so small you would need a strong microscope to see one.
Single means 1... multi means more.... lets see if we use common sense a single cell organism has one cell and a multicellular organism has more than one cell.
Every organism you can see. Animals,plants are examples

Amoeba are single-celled organisms which are very often large enough to see with the naked eye, and are sometimes as large as grapes.As the term "single-celled organism" implies, the entire creature is in fact one cell.an eukaroytic cell
No. Single-celled organisms are too small to see without a microscope. An anteater can be mroe than 2 metres head to tail.
one-celled organisms like amoebas don't "see" they detect changes in their environment
The statement which best compares a multicellular organism to a single-celled organism is their functions. While multicellular organisms use organ systems to perform life functions, single-celled organisms do not use organs for the life functions.
