QuestionAnswer

What is osmosis? The movement of water molecules which is the higher concentration to a low concentration in water.
What is permeable? Allows any molecules to diffuse across membrane.
What is semi - permeable? Allows certain molecules to diffuse across membrane. (Cell membrane)
What is non - permeable? Allows no certain or any molecules to diffuse across membrane. (Cell wall)
What is nucleus? Controls all activites that is growth and reproduction which is in both animal and plant cell.
What is cell - membrane? Allows certain molecules to diffuse in or out of the cell. Molecules diffuse in or out of the cell which has 2 phosphourous layers interconnected. It is in both animal and plant cell.
What is cell - wall? Protects and supports its cell; allows no molecules to go in or out which is plant cell.
What is chromosomes? Proteins that contain DNA which has coded information for making molecules in both animal and plant cell.
What is Rough Endoplasmic Reticulum? Produces and stores proteins which is in both animal and plant cell.
What is Smooth Endoplasmic Reticulum? Produces and stores fats or oils which is in both animal and plant cell.

What is Mitochondria? converges sugar into energy which is in both animal and plant cell.
What is Vacuole? Stores water, minerals and vitamins which is much bigger in a plant cell that is in both animal and plant cell.
What is Lysosomes? Breaks down food, including bacteria and old/damaged organelles which is in animal cell.
What is chloroplast? Uses sunlight to make its own food which is known as photosynthesis. The formula is CO2 + H2O + Sunlight --> Sugar + O2. It is in plant cell.
