What happens to cellular respiration after photosynthesis? | The stored molecules will break down in the presence of oxygen and will be converted into energy in the form of ATP (Adrenosine Triphosphate) |
Does plants respond to different changes in their environment? | Yes |
Reproduction in plants can be what? | Sexual or Asexual |
What does asexual reproduction in plants means? | produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place. |
What does sexual reproduction in plants means? | flowering plants involves the production of male and female gametes. Through pollination process |
Does plants have the ability to adapt to changes in the environment? | Yes |

Used for attachment
long filamentous polymeric protein structures located at the surface of bacterial cells. They enable the bacteria to bind to specific receptor structures and thereby to colonise specific surfaces. | Fimbriae |
