Pearson Chapter 14 Review

Front

What is the evolutionary milestone shown in the transition from prokaryotes to eukaryotes?

Back

The transition from prokaryotes to eukaryotes represents a significant evolutionary milestone where more complex cellular structures and functions developed.

Front

Which domain of life includes organisms that can thrive in extreme environments, such as high-temperature water?

Back

The Archaea domain includes organisms that can thrive in extreme environments, such as high-temperature water.

Front

Why do leftovers in your refrigerator eventually grow mold?

Back

Leftovers grow mold because fungi are widespread and reproduce quickly, allowing them to colonize food.

Front

What organelle is believed to have developed as a result of a symbiotic relationship?

Back

The mitochondrion is believed to have developed as a result of a symbiotic relationship between early eukaryotic cells and engulfed prokaryotic cells.

Front

What is a key difference between prokaryotes and eukaryotes?

Back

Prokaryotes lack a nucleus that separates their DNA from the rest of the cell, while eukaryotes have a defined nucleus.

Front

Define prokaryotes.

Back

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

Front

What are eukaryotes?

Back

Eukaryotes are organisms whose cells contain a nucleus and membrane-bound organelles, including animals, plants, fungi, and protists.

Front

What is symbiosis?

Back

Symbiosis is a close and long-term interaction between two different biological species, which can be mutualistic, commensalistic, or parasitic.

Front

What role do fungi play in ecosystems?

Back

Fungi play a crucial role in ecosystems as decomposers, breaking down organic matter and recycling nutrients back into the environment.

Front

What is the function of the mitochondrion?

Back

The mitochondrion is known as the powerhouse of the cell, responsible for producing ATP through cellular respiration.
