Flashcard Content Overview

Cells are the basic unit of life and can be thought of as the building blocks of life. They can be eukaryotic or prokaryotic and contain tiny structures called organelles. These organelles work together to perform jobs, like the organs in our bodies. Some of the organelles you will learn about are: nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, and vacuoles.

Depending on whether a cell has, or doesn't have, a nucleus affects which organelles will be inside. Also, plant cells and animal cells have different organelles.

Remember, cells, cells, they're made of organelles!

Nucleolus
The center of the nucleus where ribosomes are formed

Microfilaments
One of the components that make up the cytoskeleton; thin threads made of protein that help the cell keep its shape
Ribosomes
Small pieces of RNA found throughout the cytoplasm and on rough endoplasmic reticulum; their function is to make proteins
Endoplasmic reticulum
The transport system of the cell; made of lipid membranes that move proteins from one location to another
Rough endoplasmic reticulum (ER)
The transport system in the cell that contains ribosomes, which make proteins
Smooth endoplasmic reticulum (ER)
Transport system in the cell that does NOT contain ribosomes; main function is to assemble the lipid part of the cell membrane
Golgi apparatus (Golgi bodies)
The organelle that changes, sorts, packages, and ships proteins as they leave the endoplasmic reticulum
Lysosomes
Organelle that is filled with digestive enzymes that break down toxic cell waste; also breaks down proteins, lipids, and carbohydrates into more useful forms for the cell
Mitochondria
The powerhouse of the cell that makes energy by converting food into more usable forms for the cell
Vacuoles
Large, sac-like structures that store water, proteins, carbohydrates, and salts in a cell; these are larger in plants
Vesicles
Smaller structures found in eukaryotic cells that store and move things between the different organelles and between the cell and the outside environment
Chloroplasts
Plastids that contain chlorophyll
If a cell is like a factory, what would the nucleus be?
This organelle would function like the main office.
If a cell is like a factory, what would the Golgi apparatus be?
This organelle would be like the mail room of the factory.
If a cell is like a factory, what would the mitochondria be?
This organelle would be like the power plant of a factory.
If a cell is like a factory, what would the endoplasmic reticulum be?
This organelle would be like the internal delivery system, or post office, of the factory.
Cell wall
The rigid covering of plant cells that support the plant cell and give it structure; made of large carbohydrates called cellulose
Turgor pressure
Created when plant cells fill with water; prevents wilting
