Cells & Diffusion

Part A

TermDefinition
Animal & Plant Cells: Smooth Endoplasmic Reticulum Produced & stores fat and oils.
Animal & Plant Cells: Rough Endoplasmic Reticulum Produces & stores proteins.
Animal & Plant Cells: Nucleolus The nucleolus is a small part inside the nucleus of a cell that makes tiny pieces called ribosomes, which help build proteins.
Animal & Plant Cells: Chromosomes Proteins that contain DNA which has coded information for making certain molecules.
Animal & Plant Cells: Nucleus Controls all activities of the cell; growth and reproduction.
Animal & Plant Cells: Ribosomes Helps Rough ER make proteins and is attached to the Rough ER.
Animal & Plant Cells: Mitochondria Converts sugar into energy for the cell. Powerhouse of the cell.
Animal & Plant Cells: Cell Membrane Allows certain molecules to go in or out of the cell. Molecules diffuse in our out of a cell.
Animal & Plant Cells: Cytoplasm Fluid in the cell, gel like, allows organelles to move around.
Animal & Plant Cells: Golgi Bodies Modifies & packages proteins from the Rough ER with enzymes.
Animal & Plant Cells: Vacuoles Stores water, minerals & vitamins and is much bigger in plant cells than animal cells.
Animal Cell: Lysosomes Breaks down food, invading bacteria & old/damages organelles. If a cell doesn't kill itself you have cancer and a possibly a tumor.
Animal Cell: Centrioles Helps with the cell division (mitosis) and spindle fibres come from here.
Plant Cell: Cell Wall Supports and protects the cell; does not allow molecules in or out.
Plant Cell: Chloroplasts & Photosynthesis Uses sunlight to make its own food. Plants make their own sugar using the Photosynthesis equation: CO2+H2O+light = Sugar +O2.
Diffusion & example Movement of molecules from areas of high concentration to low concentration. Ex: perfume.
Osmosis & example Movement of WATER molecules from high concentration of WATER to low concentration of WATER. Ex: your hands when you exit a pool.
Permeable Allows any molecules to diffuse across membrane.
Semi-permeable Allows certain molecules to diffuse across membrane.
Non-permeable Allows no molecules to diffuse across membrane.

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.
