Cell Struc. & Func'n

Study the different structures and functions of cellular content

QuestionAnswer
These cells are categorized by the absence of a membrane-bound nucleus Prokaryotic Cells
Consists of a phospholipid bilayer embedded with protein molecules; separates contents of the cell from the surrounding environment Plasma Membrane
Is a semifluid medium inside the cell; composed of water, salts, and dissolved organic molecules Cytoplasm
These cells are categorized by their complexity, especially by the presence of a nucleus Eukaryotic Cells
Any well-defined subcellular structure that performs a particular function Organelle
In many cells, it is the location where genetic information is stored; where DNA and RNA are synthesized Nucleus (nuclei)
Concentrated (dark) area of chromatin, rRNA; where ribosomes are made Nucleolus (nucleoli)
Responsible for the folding, modification, and transport of proteins Rough Endoplasmic Reticulum
Has various functions, known for its role in lipid synthesis Smooth Endoplasmic Reticulum
Protein and RNA; in two subunits; protein synthesis Ribosomes
Stack of small membranous sacs used in processing, packaging, and distribution of proteins and lipids; "post-office" Golgi Apparatus (Golgi Body)
Membranous vesicle involved in intracellular digestion of food, particles, waste, foreign invaders, and cell parts; contains digestive enzymes Lysosome
In plants, they are known as membranous vesicles used for storage of water Vacuole
In plant cells; traps sunlight, location of photosynthesis Chloroplasts
Breaks down food (sugar) for energy (cellular respiration) Mitochondrion (Mitochondria)
9+0 pattern of microtubules Centriole
Made of microtubules, intermediate filaments, and actin filaments; give shape to the cell and responsible for the movement of its parts Cytoskeleton
Highly condensed structure containing genetic information; humans have 46 of them Chromosomes

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
