Mitochondria (The Power Plant)
Endomembrane System (The Mum)
Nucleus (The Brain)

Click and drag
- This is the name given to a cell’s network of internal membranes - The endomembrane system regulates protein traffic and performs metabolic functions in the cell - Overall function is to produce, store, and export biological molecules - Degrade potentially harmful substances
The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).
- Oblong shaped organelles that are found in the cytoplasm of every eukaryotic cell. In the animal cell, they are the main power generators, converting oxygen and nutrients into energy. - Organelles where energy is generated in the form of adenosine triphosphate (ATP). - ATP is the ‘energy currency’ of the cell. Cells breakdown this molecule to release energy wherever and whenever it is needed, - They contain their own DNA and are self-replicating organelles and divide by fission - The number of mitochondria in a tissue reflects the energy requirement of that tissue. For example cardiac muscle has a high number of .......................... (as the heart is continuously beating).
These straight, hollow cylinders are found throughout the cytoplasm of all eukaryotic cells (prokaryotes don't have them) and carry out a variety of functions, ranging from transport to structural support.

Centrioles (The EA)

Endoplasmic Reticulum (The Chocolate Digestive)
Endosomes and Endocytosis (The Foetal Position)

Click and drag
A network of sacs that manufactures, processes, and transports chemical compounds for use inside and outside of the cell. It is connected to the double-layered nuclear envelope, providing a pipeline between the nucleus and the cytoplasm.
Self-replicating organelles made up of nine bundles of microtubules and are found only in animal cells. They appear to help in organizing cell division, but aren't essential to the process.
Membrane-bound vesicles, formed via a complex family of processes collectively known as endocytosis, and found in the cytoplasm of virtually every animal cell. The basic mechanism of endocytosis is the reverse of what occurs during exocytosis or cellular secretion. It involves the invagination (folding inward) of a cell's plasma membrane to surround macromolecules or other matter diffusing through the extracellular fluid.
For single-celled eukaryotes, ........................ are essential for the locomotion of individual organisms. In multicellular organisms, cilia function to move fluid or materials past an immobile cell as well as moving a cell or group of cells.

The main function of these microbodies is digestion. ....................... break down cellular waste products and debris from outside the cell into simple compounds, which are transferred to the cytoplasm as new cell-building materials.
Very broad class of fibrous proteins that play an important role as both structural and functional elements of the cytoskeleton. Ranging in size from 8 to 12 nanometers, intermediate filaments function as tension-bearing elements to help maintain cell shape and rigidity.
The distribution and shipping department for the cell's chemical products. It modifies proteins and fats built in the endoplasmic reticulum and prepares them for export to the outside of the cell.
Solid rods made of globular proteins called actin. These filaments are primarily structural in function and are an important component of the cytoskeleton.

Peroxisomes (The Personal Trainer)
Plasma Membrane (The M25)
Rough ER
Smooth ER

Click and drag
- Has bound ribosomes attached, which secrete proteins into the cisternal space - Proteins produced here are destined for excretion from the cell or for attachment to the cell membrane - New proteins made at the rER are folded and processed (eg sugar chains added). - They are transported from the ER to the Golgi apparatus in vesicles.
Peroxisomes absorb nutrients that the cell has acquired. They are very well known for digesting fatty acids. They also play a part in the way organisms digest alcohol (ethanol). Because they do that job, you would expect liver cells to have more peroxisomes than most other cells in a human body.
- Within the cisternae (the cavities) of the smooth ER: - Lipids (including steroids) are made - Carbohydrates are broken down - Poisons may be detoxified - Calcium is stored
All living cells have a plasma membrane that encloses their contents. In prokaryotes, the membrane is the inner layer of protection surrounded by a rigid cell wall. Eukaryotic animal cells have only the membrane to contain and protect their contents. These membranes also regulate the passage of molecules in and out of the cells. They are composed of lipids (mainly phospholipids), proteins and carbohydrates (attached to the phospholipids and proteins).
