| Question | Answer |
| What is Bio mimicry? | Is Innovation within nature, mimicking nature to make our lives better |
| What is Nanotechnology | Is the branch of tech that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of singular atoms and molecules |
| What is Bio luminescence? | Is the biochemical output of light by living organisms |
| What is Desalination? | The removal of salt from water |
| What is the difference between a plant cell and an animal cell? | A plant cell has a cell wall to protect the cell where as an animal cell doesn't |
| What is a eukaryotic cell? | Is any organism whose cells have a nucleus and other organelles enclosed within membranes |
| What is a prokaryotic cell? | are unicellular organisms which don't have a nucleus |
| What is a stem cell? | Are cells that can become different types of specialized cells |
| What is diffusion? | Is the spread of gas particles or any other substance in a solution, resulting in a net movement from a region |
| What is osmosis? | Is the diffusion of liquid molecules from an area of high concentration to an area of low concentration, across a partially permeable membrane |
| How is magnification calculated? | Magnification = measured size/actual size |
| How is actual size calculated? | Actual size = measured size/magnification |
| A plant cell in a photograph measures 15 mm across. If the actual size of the cell is 0.015 mm, what is the magnification in the photograph? | magnification = Measured size/actual size =15mm/0.015 = Magnification = x1000 |
| The nucleus in a photograph of a cell measures 3 mm across. If the magnification in the photograph is × 500, what is the actual size of the nucleus? | Actual size = measured size/magnification = 3mm/500 =Magnification = 0.006 |
| What is Mitosis? | Is a type of cell division that results in two daughter cells having the same number and kind of chromosomes as the parent nucleus |
