FLASHCARD QUESTION
Front
Organelle Noun
[or-guh-nel]
Back
Organelle
A specialized structure inside a cell with a specific job, contributing to the overall function of the cell.
Example: This image shows a cutaway view of a chloroplast, which is an example of an organelle found inside plant cells.

FLASHCARD QUESTION
Front
Cell Membrane Noun
[sel mem-brayn]
Back
Cell Membrane
A thin, flexible barrier around a cell that controls which substances are able to enter and leave the cell.
Example: This diagram shows the cell membrane is a barrier with proteins embedded in it that act as channels, allowing it to control what enters and leaves the cell.

FLASHCARD QUESTION
Front
Cytoplasm Noun
[sy-toh-plaz-uhm]
Back
Cytoplasm
The entire region of a cell between the nucleus and the cell membrane, including the cytosol and organelles.
Example: This diagram shows that the cytoplasm is the jelly-like substance that fills the entire cell and holds all the organelles in place.

FLASHCARD QUESTION
Front
Cytosol Noun
[sy-toh-sol]
Back
Cytosol
The jelly-like fluid portion of the cytoplasm that fills the cell and supports various essential chemical reactions.
Example: This image shows a simple diagram of a cell, with an arrow pointing to the jelly-like fluid that fills the cell and surrounds the organelles.

FLASHCARD QUESTION
Front
Nucleus Noun
[noo-klee-uhs]
Back
Nucleus
The large organelle that contains the cell's genetic material and acts as the command center, directing cell activities.
Example: This diagram shows a cutaway view of the cell's nucleus, labeling its key parts like the chromatin (genetic material) and the central nucleolus.

FLASHCARD QUESTION
Front
Nucleolus Noun
[noo-klee-oh-luhs]
Back
Nucleolus
A small, dense structure found inside the nucleus that is responsible for building the parts of ribosomes.
Example: This diagram shows the nucleolus as a round structure located inside the cell's nucleus, along with other nuclear parts like chromatin.

FLASHCARD QUESTION
Front
Nuclear Envelope Noun
[noo-klee-er en-vuh-lohp]
Back
Nuclear Envelope
The double membrane surrounding the nucleus that contains pores to regulate traffic of molecules in and out.
Example: This diagram shows the nuclear envelope as the protective outer layer of the cell's nucleus, with small openings called nuclear pores.
