Front

What type of cells do animals have?

Back

Eukaryotic cells are the type of cells that animals have, characterized by a nucleus and membrane-bound organelles.

Front

What is passive transport?

Back

Passive transport is a type of cellular transport that does not require energy, allowing substances to move across cell membranes along their concentration gradient.

Front

Who contributed to the cell theory?

Back

Key contributors to the cell theory include Robert Hooke, Anton Van Leeuwenhoek, and Matthias Schleiden.

Front

What is a characteristic of cancer cells?

Back

Cancer cells do not respond to growth inhibitors, allowing them to grow uncontrollably.

Front

Who gave the name 'cells' to the basic unit of life?

Back

Robert Hooke is credited with coining the term 'cells' after observing cork under a microscope.

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, unicellular organisms without a nucleus or membrane-bound organelles, such as bacteria.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.
