Nucleus - The Cell's Control Centre
Think of the nucleus as the brain of the cell - it's literally running the whole show. This massive organelle is surrounded by a nuclear envelope (a double membrane) that acts like a security barrier, keeping the cell's most precious cargo safe inside.
Inside the nucleus, you'll find chromatin - basically your DNA wrapped around proteins called histones. When the cell isn't dividing, chromatin just chills out in a relaxed, spread-out form. But when it's time to divide, it tightens up into those chromosomes you've probably seen in textbook diagrams.
The nucleolus is like a little factory inside the nucleus that's constantly churning out ribosomes. Nuclear pores act as selective doorways, letting important molecules like mRNA escape to the cytoplasm whilst keeping other substances safely inside.
Quick Tip: Remember that the nucleus contains your entire genome and provides all the instructions for protein synthesis - it's essentially your cell's instruction manual!
Rough Endoplasmic Reticulum - The Protein Factory
The rough endoplasmic reticulum (RER) gets its bumpy appearance from thousands of ribosomes stuck to its surface - imagine a conveyor belt covered in tiny protein-making machines. This network of membranes creates fluid-filled spaces called cisternae that connect directly to the nuclear envelope.
These cisternae aren't just empty spaces - they're like highways for transporting newly-made proteins around the cell. The large surface area means loads of ribosomes can pack onto the membrane, making this organelle incredibly efficient at protein production.
Once proteins are assembled by the ribosomes, they pass through the membrane into the cisternae and get shipped off to the Golgi apparatus for final touches and packaging.
Exam Focus: RER is all about making proteins that will be exported from the cell - this is different from free ribosomes that make proteins for use inside the cell.
Smooth Endoplasmic Reticulum - The Lipid Specialist
Unlike its rough cousin, the smooth endoplasmic reticulum (SER) has no ribosomes attached, giving it a smooth surface. It's still a network of membranes with fluid-filled cavities, but it's got a completely different job.
The SER is basically the cell's chemistry lab for lipid metabolism. It's packed with enzymes that synthesise cholesterol, phospholipids for cell membranes, and steroid hormones. If your cell needs fats or lipids, this is where the magic happens.
You'll also find SER working hard in your digestive system, helping with the absorption and transport of lipids from food. It's particularly abundant in cells that produce lots of hormones or need to process fats.
Remember: Rough ER = proteins, Smooth ER = lipids. This distinction comes up frequently in exam questions!
Golgi Apparatus - The Cell's Post Office
The Golgi apparatus looks like a stack of pancakes made from flattened membrane sacs. Secretory vesicles constantly bring materials to and from this organelle, like delivery trucks at a busy warehouse.
This is where proteins from the RER get their final modifications. The Golgi adds sugar molecules to create glycoproteins, attaches lipids to make lipoproteins, and folds proteins into their proper 3D shapes. Think of it as quality control and packaging combined.
Once proteins are properly modified, they're packaged into vesicles that either get stored in the cell, incorporated into the plasma membrane, or exported outside the cell entirely.
Key Point: The Golgi apparatus is essential for protein trafficking - without it, proteins would never reach their correct destinations in the cell.
Mitochondria - The Cell's Power Plants
Mitochondria are the ultimate energy converters, turning glucose and oxygen into ATP (the cell's energy currency) through aerobic respiration. These rod-shaped organelles are typically 2-5 μm long and have a unique double membrane structure.
The inner membrane is folded into structures called cristae, which massively increases the surface area for energy-producing reactions. The fluid-filled matrix inside contains enzymes needed for respiration, plus the mitochondrion's own DNA and ribosomes.
Because they have their own genetic material, mitochondria can replicate themselves when the cell needs more energy. You'll find loads of them in metabolically active cells like liver cells and neurons, where energy demands are constantly high.
Fascinating Fact: Mitochondria can exist independently because they have their own DNA - some scientists think they were once separate organisms that moved into our cells millions of years ago!
Chloroplasts - The Plant's Solar Panels
Chloroplasts are exclusive to plant cells and some protoctists, and they're the reason plants can make their own food. These large organelles are surrounded by a double membrane envelope.
Inside, you'll find stacks of flattened sacs called thylakoids, which contain the green pigment chlorophyll. Each stack is called a granum (plural: grana), and these are where the light-dependent reactions of photosynthesis occur. The fluid-filled stroma surrounds the grana and hosts the light-independent reactions.
Like mitochondria, chloroplasts have their own DNA and can self-replicate. They're most abundant in leaf cells, especially in the palisade mesophyll layer where they can capture maximum sunlight.
Two-Stage Process: Stage 1 (grana) captures light energy and splits water; Stage 2 (stroma) uses that energy to convert CO₂ into carbohydrates.
Ribosomes - The Protein Assembly Lines
Ribosomes might be tiny (about 20nm in diameter), but they're absolutely crucial for life. Made of ribosomal RNA (rRNA) and proteins, these spherical organelles are manufactured in the nucleolus as two separate subunits that combine in the cytoplasm.
You'll find ribosomes in two locations: some float freely in the cytoplasm, whilst others attach to the rough endoplasmic reticulum. Free ribosomes make proteins that the cell uses internally, whilst bound ribosomes on the RER produce proteins for export.
During protein synthesis, ribosomes read the genetic code from mRNA and assemble amino acids in the correct order to build proteins. It's like having molecular machines that can read instructions and build exactly what the cell needs.
Location Matters: Free ribosomes = proteins for internal use; bound ribosomes = proteins for export. This is a common exam distinction!
Cellulose Cell Wall - The Plant's Armour
The cellulose cell wall is like a protective suit of armour that surrounds plant and bacterial cells (though bacterial walls aren't made of cellulose). Made from bundles of long cellular fibres and chains of beta glucose, it sits just outside the plasma membrane.
This tough structure prevents plant cells from bursting when they become turgid (swollen with water). It provides incredible strength and support, helping maintain the cell's shape and contributing to the structural integrity of the entire plant.
Unlike the plasma membrane, cell walls are permeable, allowing solutions to pass through freely. This means water and dissolved substances can move between cells without crossing membranes.
Fun Fact: Fungi also have cell walls, but theirs contain chitin (the same stuff in insect exoskeletons) instead of cellulose.
Vacuoles - The Cell's Storage Tanks
Plant cells have permanent vacuoles surrounded by a membrane called the tonoplast, whilst animal cells only have temporary vacuoles when needed. These fluid-filled sacs contain cell sap - a mixture of water and various dissolved substances.
When a plant vacuole is full of water, it pushes against the cell wall, making the cell turgid. This is brilliant for plant support - when all the cells are turgid, the entire plant stays upright and rigid, especially important for non-woody plants that don't have lignin for structure.
If plants don't get enough water, their vacuoles shrink, cells lose turgor pressure, and the plant wilts. It's a simple but effective system for maintaining plant structure using water pressure.
Plant Support: Turgid cells = upright plant; non-turgid cells = wilted plant. This explains why plants droop when they need watering!
Lysosomes - The Cell's Recycling Centre
Lysosomes are like the cell's waste disposal and recycling system rolled into one. These small, membrane-bound sacs form from the Golgi apparatus and contain powerful hydrolytic enzymes that can break down almost anything.
The single membrane surrounding each lysosome is crucial - it keeps those destructive enzymes safely contained until they're needed. You'll find loads of lysosomes in phagocytic cells like neutrophils and macrophages, which need to digest invading bacteria and other pathogens.
Lysosomes excel at lysosomal digestion - they can engulf old, worn-out organelles or foreign material, break them down completely, and return the useful components to the cell for reuse. It's the ultimate recycling system.
Safety First: Those powerful enzymes could destroy the cell if they escaped, so the lysosomal membrane is absolutely essential for keeping them contained until needed.
