Changing Biodiversity
What is biodiversity?
The sum of the different forms of living things in a given area or population
What are natural disasters?
A force of nature that results in catastrophic consequences
What is a cell?
The basic structural and functional unit of living organisms
What is the cell membrane?
A lipid bilayer that surrounds the cytoplasm of a cell, separating the inside of the cell from the environment and controlling what enters and leaves the cell
What is an organelle?
A structure inside a cell that performs a specific function or set of functions
What is deforestation?
Removal of a forest or stand of trees, which are then used for nonforest purposes
What are human activities?
Things that people do or cause to happen
What is a prokaryotic cell?
An organism that lacks a true nucleus and membrane-bound organelles
What is the cell wall?
A tough, protective barrier that surrounds the outer membrane of some types of cells
What is the cytoplasm?
The jellylike material inside the outer membrane of a cell that holds the nucleus, organelles, and other components of the cell
What are invasive species?
An alien (non-native to the ecosystem) species, usually brought to an area by humans, that competes for resources and causes problems for the native species within an ecosystem
What is climate change?
A long-term change in the temperature range and related environmental variables for regions of Earth
What is the nucleus?
The organelle where a eukaryotic organism's genetic material is located; the control center of the cell
What is the chloroplast
The organelle where photosynthesis occurs in plant cells
What is deoxyribonucleic acid (DNA)?
The carrier of genetic information present in nearly all organisms; forms a double helix
What is ocean acidification?
The process that decreases the pH of the ocean due to an increase in the absorption of carbon dioxide
What is global warming?
An increase in the average temperature of Earth's atmosphere, especially a sustained increase great enough to cause changes in the global climate
What is a ribosome?
A structure made of protein and rRNA that converts messenger RNA sequences into amino acid sequences with the help of transfer RNAs
What is the mitochondrion?
An organelle in the cytoplasm of eukaryotic cells that functions in energy production; the power factory of the cell
What is the golgi body?
An organelle that packages and sorts materials for transport outside of the cell
Deforestation, Invasive Species, Human Activities, Climate Change, Global Warming, Ocean Acidification, Natural Disaster
How does human activity cause biodiversity to be lost?
Answer may vary
What is a eukaryotic cell?
An organism whose cells contain a true nucleus and membrane-bound organelles
What is the endoplasmic reticulum?
A system of membrane-enclosed sacs and tubes in the cytoplasm of eukaryotic cells where proteins and lipids are synthesized
What is the Endosymbiotic Theory?
The theory that several key organelles found in eukaryotes originated as a symbiosis between separate single-celled organisms
