Yes some cells can be seen without the use of a microscope. According to Beyond Books.com (2007.), "Most cells are very small and can't be seen without magnification. [However,] An ostrich egg, which may weigh up to two pounds, is actually a single cell. A neuron, is also a single nerve cell that can be seen without a micrscope." (Beyond Books.com, 2007.)

Yes, cells can be seen with a microscope.
No, human cells are too small to be seen with the naked eye. A microscope is needed to magnify the cells in order to see them.

Single cells are the smallest cells that can preform all of the function in life and cannot be seen without a microscope. The above answer should say most cells can not be seen without a microscope. There are exceptions to this rule as say a chicken egg or 2 foot long strands of neurons are also single cells.
Most protists are microscopic and cannot be seen without a microscope due to their small size. However, some protists, such as giant kelp, are macroscopic and can be seen without the aid of a microscope.
All animals can be seen without a microscope.

Impossible* Hooke's discovery dealt with cells, which are extremely tiny that it is impossible to be seen with the naked eye. So, without the microscope, he would not have been able to see it.
No, most bacteria are not visible to the naked eye due to their small size, which typically ranges from 0.2 to 2 micrometers. A microscope is required to observe individual bacterial cells.
Cork Cells!
Just 'bateria'; it is commonly-understood that samba percussionists can be seen without a microscope.
