Flower Shop Cell Analogy
Cell Wall : The Walls of the Flower Shop
Plasma Membrane : Door
The plasma membrane consists of a bilayer of phospholipids with various proteins attached to or embedded in it. It is the membrane at the boundary of every cell that acts as a selective barrier, regulating the cell's chemical composition. Its selective barrier allows passage of enough oxygen, nutrients, and wastes to service the entire cell.
Cytoplasm : Floor
Mitochondria : Electrical Outlets
Mitochondria are organelles in eukaryotic cells surrounded by a double membrane that serve as the site of cellular respiration: a metabolic process that uses oxygen to generate ATP. It converts energy to forms that cells can use for work.
Nucleus : Flower Arrangement Book
The nucleus is an organelle of a eukaryotic cell surrounded by a double membrane that contains the genetic material in the form of chromosomes, made up of chromatin. The nucleolus is located within the nucleus. The nucleus functions as the control center of the cell and stores genetic information.
Ribosomes : Florists
Rough Endoplasmic Reticulum : "Assembly Line"
Smooth Endoplasmic Reticulum: Refrigerators
Golgi Apparatus : Packaging
Vacuoles : Cabinets
Lysosomes : Recycle/Trash/Compost Bin
Chloroplast : The "Break Room"
The cell wall is a protective layer external to the plasma membrane that distinguishes plant cells from animal cells. Polysaccharides, such as cellulose in plant cells, are important structural components of cell walls. It functions to maintain the cell shape, protect the cells from mechanical damage, and prevent excessive uptake of water. The cell wall consists of a primary cell wall, which is first secreted by young plant cells, and a secondary cell wall, which is secreted by mature plant cells.
The exterior wall of the flower shop is the cell wall; it is made of brick or another material. It surrounds the shop and supports the structure as a whole.
The door is a barrier that people must pass through in order to enter the shop. The door can be locked or unlocked to allow entry for specific people.
When florists enter the shop, they turn on the lights and make sure all of the refrigerators are running. The refrigerators are plugged in to the outlets, and electricity powers the refrigerators. The cash register, computers, and phones used for purchases also require electrical outlets.
In eukaryotic cells, the cytoplasm is the interior of the cell which refers to the region between the nucleus and the plasma membrane. Within the cytoplasm, various organelles are suspended in the cytosol. The cytoplasm helps hold the organelles in their place while allowing substances to travel within the cell and gives the cell its shape.
The floor of the flower shop is the cytoplasm. All of the materials, machines, devices, and people are contained on top of the floor and can travel across it.
Once the florists are situated, they get to work and pull out a flower arrangement book as a guide to help them put together flower arrangements. The book stores information about different flowers and displays.
Ribosomes are complexes of rRNA and protein molecules that function as a site of protein synthesis in the cytoplasm and on the outside of rough endoplasmic reticulum. In eukaryotic cells, each subunit of the ribosome is assembled in the nucleus.
Rough ER is the portion of the endoplasmic reticulum with ribosomes attached and is found in eukaryotic cells. Rough ER aids in the synthesis of secretory and other proteins from bound ribosomes, adds carbohydrates to proteins to make glycoproteins, and produces new membrane.
Smooth ER is the portion of the endoplasmic reticulum that is free of ribosomes found in eukaryotic cells. Smooth ER synthesizes lipids, metabolizes carbohydrates, stores calcium ions, detoxifies drugs and poisons, and manufactures phospholipids.
The Golgi apparatus is an organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum and synthesize some products, notably noncellulose carbohydrates. It modifies proteins, carbohydrates on proteins, and phospholipids. It also sorts and packages materials into transport vesicles.
Vacuoles are membrane-bounded vesicles whose specialized function varies in different kinds of cells. They are found in both animal and plant cells, but they are more prominent in plant cells. Vacuoles aid in digestion, storage, waste disposal, water balance, cell growth, and protection. It stores water, potassium ions, and calcium ions.
Lysosomes are membrane-enclosed sacs of hydrolytic enzymes found in the cytoplasm of animal cells. Lysosomes breakdown ingested substances, cell macromolecules, and damaged organelles for recycling.
Chloroplasts are organelles found in plants that absorb sunlight and use it to drive synthesis of organic compounds from carbon dioxide and water. Chloroplasts convert energy to forms that cells can use for work.
After the florists find the desired arrangement, they themselves begin to assemble the flowers by picking and choosing specific plants they need to use. The florists synthesize flower arrangements.
The florists work side by side to complete the flower arrangements. For example, one florists will place roses, the next will place daisies, and another will place filler flowers as the arrangement travels along the "assembly line." The flowers accumulate along the line.
Once the arrangement is completed by the "assembly line" of florists, the flowers are stored in a floral refrigeration system (a refrigerator) so that the flowers won't wilt before they are transported out of the shop. The arrangement is also kept isolated from other flowers to prevent mix-ups and "cross-contamination."
After the flower arrangements are completed, they are ready to be transported. The flowers are modified and finished off. The flowers are placed into packaging and boxes and laced with ribbons. Small personal messages can be attached which help identify the person who will receive the arrangement. The arrangements are then transported out of the shop by an automobile.
The florists completed their job and now have to place any left over material back into storage. Ribbon, packaging, labels, and cutting utensils are placed back into cabinets. Leftover flowers are placed back into their designated locations.
Any leftover flowers that cannot be used again can be placed in compost bins; the compost can then be used as nourishment for other growing flowers. Packaging that is recyclable can be placed in the recycle bin, and other items are placed in the trash bin.
Clean-up time is over; the florists need to nourish their bodies and gain energy to fill more orders. They go to the "break room" and eat food. They can have salads and other foods which contained chloroplasts that participated in photosynthesis. Once they have eaten, they can go back to the flower arrangement book and fill another order.
What if the flower shop was mobile?
The flower shop could travel around the city on wheels. The wheels of the mobile shop parallel to the function of flagella in both plant and animal cells; sperm of animals and some plants have flagella. The motor of the mobile flower shop produces power which is delivered to the transmission, which in turn transfers that power through the drive shaft (the rear wheels). The car is in motion.
Flagella are long cellular appendages specialized for locomotion. A flagellum has an undulating motion that generates force in the same direction as the flagellum's axis, like the tail of a fish. The cell is in motion.
