A Tour of the Cell

What was the belief of spontaneous generation?

• Life arises from pre-existing life.

• Non-living matter can create living organisms.

• Life is created by a unified stork theory.

• Cells are the basic building blocks of life.

Who first observed and named 'cells' and what did they resemble to him?

• Theodor Schwann, tiny animals.

• Matthias Schleiden, plant structures.

• Robert Hooke, small rooms in monasteries.

• Rudolf Virchow, multiplying organisms.

Which statement is NOT part of the Classical Cell Theory?

• All organisms are made of cells.

• The cell is the basic building block of life.

• All cells come from pre-existing cells that have multiplied.

• Life can arise spontaneously from non-living matter.

What is a key difference between eukaryotic and prokaryotic cells?

• Eukaryotic cells are always single-celled, while prokaryotic cells are always multicellular.

• Prokaryotic cells have a defined nucleus, while eukaryotic cells do not.

• Eukaryotic cells have a defined nucleus and membrane-bound organelles, while prokaryotic cells do not.

• Prokaryotic cells are larger and more complex than eukaryotic cells.

In the "Cellular City" analogy, what role does the nucleus (City Hall) play?

• It packages proteins into vesicles at the Golgi

• It transports cargo along protein filaments

• It sends genetic instructions out in the form of RNA

• It modifies proteins in the rough ER

What cellular component is responsible for translating RNA instructions into proteins?

• Nucleus

• Mitochondria

• Ribosome

• Golgi Apparatus

Which organelle is primarily responsible for manufacturing lipids, including components of the cell membrane and hormones?

• Rough Endoplasmic Reticulum

• Golgi Apparatus

• Smooth Endoplasmic Reticulum

• Mitochondria

Why are chloroplasts not included in the animal cell tour?

• Chloroplasts and mitochondria are the same organelle with different names

• Chloroplasts are too small to see with current microscopes

• Chloroplasts are only found in plant cells, not animal cells

• Animals lost chloroplasts during evolution and never had them

The hypothesis that mitochondria and chloroplasts originated from prokaryotic cells merging in a symbiotic relationship was significantly advanced by which scientist?

• Robert Hooke

• Lynn Margulis

• Anton van Leeuwenhoek

• Matthias Schleiden

What is the primary factor that limits the maximum size a cell can attain?

• The amount of DNA in the nucleus

• The number of ribosomes available for protein synthesis

• The surface-area-to-volume ratio

• The availability of ATP
