Robert Hooke first observed cells in cork.
Robert Hooke was the first person to observe cells.
Antonie van Leeuwenhoek is likely the first person to observe a cell nucleus. To the best of my knowledge, no human has actually a seen an atomic nucleus. Cameras and microscopes aren't yet powerful enough to observe those.
Yes, Robert Hooke was the first person to observe cells under a microscope in 1665. He coined the term "cell" after observing the compartments of a cork sample, which reminded him of cells in a monastery.
Robert Hooke was the first person to observe and identify the cork cell in 1665 using a simple microscope he designed. He described the cell structure as resembling small rooms or compartments, giving rise to the term "cell."

The first person to watch something fall. OR The first person to live.
Antonie Van Leeuwenhoek is the first who observe the tiny, unicellular living things but Robert Hooke is the one who confirmed Leeuwenhoek's observations and was the first to use the term cell. Robert Hooke was also the first person to observe non-living cells.
The first person to use the term "cell" was Robert Hooke in 1665. He used a simple compound microscope to observe thin slices of cork, describing the small box-like structures he saw as cells.
The first person to observe living cells in a drop of pond water was Antonie van Leeuwenhoek, a Dutch scientist, in the 17th century. He used a single-lens microscope of his own design to make this discovery.
