Eukaryotic Cells
What makes a cell eukaryotic?
It has a nucleus enclosed by a membrane.
Who first used the word “cell” in 1665?
Robert Hooke
What organelle produces energy for the cell?
Mitochondria
In what environment are protists often found?
Water or moist soil.
Explain why eukaryotic cells represent a “remarkable step” in evolution.
Their complexity allows efficiency, specialization, and the diversity of multicellular life.
Name one type of organism that has eukaryotic cells.
Plants, animals, fungi, or protists.
Who observed living eukaryotic cells under a microscope?
Antonie van Leeuwenhoek.
What organelle is known as the “cell’s highway”?
Endoplasmic reticulum (ER).
Name two environments where animals live
Land, air, or water.
Give one reason why studying eukaryotic cells is important.
They form the basis of human biology, medicine, and biotechnology
What do eukaryotic cells have that prokaryotic cells lack?

Who discovered the nucleus in 1831?
Robert Brown.
What is the “control center” of the cell?
The nucleus.

Eukaryotic cells.
Which organelle controls cell activities?
The nucleus.
When was the term “eukaryote” officially coined?
Édouard Chatton.
Which organelle is responsible for photosynthesis?
Chloroplast.
True or False: Eukaryotic cells are only found on land.
False – they are found everywhere
What does “eukaryote” mean in Greek?
