Unit 4 Test Review

Front

What is the lytic cycle of viral replication?

Back

The lytic cycle is a process where a virus injects its genetic material into a host cell, hijacks the cell's machinery to produce new viruses, and ultimately causes the destruction of the host cell.

Front

What is the primary difference between prokaryotic and eukaryotic cells?

Back

Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

Front

What is the lysogenic cycle of viral replication?

Back

The lysogenic cycle is a process where viral DNA integrates into the host genome and remains dormant for a long time before potentially entering the lytic cycle.

Front

Which organelles are believed to have evolved from prokaryotic cells?

Back

Chloroplasts and mitochondria are believed to have evolved from prokaryotic cells.

Front

What is the significance of mitochondria and chloroplasts in eukaryotic cells?

Back

Mitochondria and chloroplasts are organelles that originated from symbiotic relationships between primitive eukaryotes and certain prokaryotes, playing crucial roles in energy production and photosynthesis.

Front

Define prokaryotic cells.

Back

Prokaryotic cells are unicellular organisms that lack a nucleus and membrane-bound organelles, such as bacteria.

Front

Define eukaryotic cells.

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles, found in organisms such as plants, animals, and fungi.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum is involved in the synthesis of proteins and lipids, and it plays a role in the transport of materials within the cell.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
