FLASHCARD QUESTION
Front
Homeostasis Noun
[hoh-mee-oh-stey-sis]
Back
Homeostasis
The process by which organisms maintain relatively constant internal physical and chemical conditions necessary for survival.
Example: This diagram shows how the body maintains a stable internal temperature (homeostasis) by reacting to heat (sweating) and cold (shivering and constricting blood vessels).

FLASHCARD QUESTION
Front
Unicellular Adjective
[yoo-ni-sel-yuh-ler]
Back
Unicellular
Describing an organism that consists of a single cell, which must perform all essential functions of life.
Example: This image shows three examples of unicellular organisms (Amoeba, Euglena, Paramecium), which are living beings made of just one single cell.

FLASHCARD QUESTION
Front
Multicellular Adjective
[muhl-tee-sel-yuh-ler]
Back
Multicellular
Describing an organism composed of many cells, which are typically specialized to perform different, coordinated functions.
Example: This diagram shows that a large muscle is made of many smaller, specialized muscle cells, which is the definition of a multicellular structure.

FLASHCARD QUESTION
Front
Prokaryote Noun
[proh-kar-ee-oht]
Back
Prokaryote
A unicellular organism that lacks a nucleus and other membrane-bound organelles, such as a bacterium.
Example: This diagram shows a bacterium, a type of prokaryote. It highlights key parts like the free-floating DNA in the nucleoid, showing it lacks a nucleus.

FLASHCARD QUESTION
Front
Eukaryote Noun
[yoo-kar-ee-oht]
Back
Eukaryote
An organism whose cells contain a nucleus and other organelles that are enclosed within membranes.
Example: This diagram shows a eukaryotic cell, which has a true nucleus containing its DNA and other specialized parts called organelles, all enclosed by a membrane.

FLASHCARD QUESTION
Front
Cell Specialization Noun
[sel spesh-uh-luh-zey-shuhn]
Back
Cell Specialization
The process in multicellular organisms where cells develop in different ways to perform particular, distinct tasks.
Example: This diagram shows how unspecialized stem cells can develop into many different types of specialized cells, like muscle, nerve, and blood cells.
7.
FLASHCARD QUESTION
Front
Chloroplast Noun
[klawr-uh-plast]
Back
Chloroplast
An organelle in plant and algal cells that captures light energy and converts it into chemical energy.
Example: This diagram shows a chloroplast, the part of a plant cell inside a leaf where photosynthesis happens, and labels its key internal structures.
