Chapter 6: Cell Tour

Cell Organelles and their functions

QuestionAnswer
Cell Theory All organisms are composed of cells Cells come from pre-existing cells
Common characteristics of ALL cells enclosed in a plasma membrane cytoplasm consists of a semifluid matrix organelles are embedded in the cytoplasm contains genes in the form of DNA
Two types of cells Prokaryotic Eukaryotic
Prokaryotic Cell Organization The smaller of the two simple structure lacks a nucleus DNA in the nucleoid region cytoplasm surrounded by the plasma membrane and outer cell wall flagella and pili may be present ribosomes
Eukaryotic Cell Organization larger of the two cells complex structure nucleous, ER, golgi apparatus, mitochondria, lysosomes, and peroxisomes (all membraneous) ribosomes, microtubules, centrioles, flagella and cytoskeleton
Functional Groups of Eukaryotes manufacture breakdown process energy support movement and communication
Nucleus "Control center"of the cell surrounded by a double membrane that contains pores to allow passage of materials between the nucleus and the cytoplasm
DNA in all cells present as as strands of chromatin
Nucleolus organelle w/in the nucleus responsible for ribosomal RNA synthesis
Endomembrane System collection of membranes either inside or surrounding the eukaryotic cell related through direct physical contact or or by the transfer of vesicles
Rough ER contains ribosomes and controls protein synthesis
Smooth ER synthesizes lipids processes materials acts as storage and detoxifies substances
Cytosol another name for the cytoplasm
Golgi Apparatus UPS of the cell chemically modifies substances recieved from the ER puts "zipcodes"on the products so they know where to go puts modified products in vesicles
Lysosomes small sacks of membrane contains low oxygen enzymes to digest substances and wastes defective ones can cause fatal diseases recycles materials in the cell
Vacuoles function in general cell maintenance holds organic substances in plants hols food or water and acts as a pump in protists
Mitochondria found in all eukaryotic cells except for anaerobic protozoans surrounded by a double membrane cell respiration takes place here not found in prokaryotes have an inner and outer membrane (cristae)
Chloroplasts found in plants and algae converts solar energy to chemical energy double membrane and the site of photosynthesis
Peroxisome similar to that of a lysosome single membrane small vesicles found in the digestive enzymes used to break down toxic material in the cell does not contain DNA or ribosomes
Detoxification vs Degredation Detoxification is the neutralization of chemicals Degredation physically chops up molecules into bits
Cytoskeleton internal cell skeleton 3D meshwork of proteins
Microfilaments rods of globular proteins
Microtubules hollow tubes of globular proteins provides as anchors for organelles forms cilia and flagella
Cilia and Flagella functions that move the cell around
Dynein protein that makes up the arms of the cilia and the flagella
Microflaments cause contraction of muscle cells
Centrioles located adjacent to the nucleus anchors and organizes the microtubules that form the spindles during cell division
3 Types of Junctions 1. Tight Junction 2. Anchoring Junction 3. Communicating Junction C.A.T
Tight Junction Blocking does not allow anything to pass through the membrane Occludin is the passing protein
Anchoring Junction holds the cell together structural support
Communicating Junction (GAP) channels between the cells rapid transport of materials
Connexin protein that makes up the GAP Junction
Extracellular Matrix often surrounded by a sticky mixture of polysaccharides and proteins extends outward from the cell membrane Lots of collagen found here

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.

To see how well you know the information, try the Quiz or Test activity.
