There are seven things that all living organisms do - these are called "Life Processes". An organism is only alive if it does all seven life processes. |

Animal and Plant Cells have Three Differences:
BOTH HAVE: 1) A Nucleus: This controls what the cell does. 2) Cytoplasm: This is a jelly-like stuff where all the chemical reactions happen. 3) A Cell Membrane: This is a thin skin around the cell - it holds the cell together and also controls what goes in and out. |
ONLY PLANTS HAVE: 1) Cell Wall: A rigid coating made of cellulose - it's gives support to the cell. 2) Vacuole: A large space filled with cell sap - a weak solution of sugar and salts. 3) Chloroplasts: These contain chlorophyll used for photosynthesis. Five |

Cells, Tissues, Organs and Organ Systems. |
A group of SIMILAR CELLS come together to make a TISSUE.
A group of DIFFERENT TISSUES work together to make an ORGAN.
A GROUP OF ORGANS work together to make an ORGAN SYSTEM, or maybe even a whole ORGANISM. E.g. Root hair cells make up root tissue, which makes up the root "organ" system, which works with other systems to make up a plant. |

|
palisade cells... ...make up palisade tissue.. ...which, with other tissues, makes up a leaf (an organ)... ...which, with other leaves, makes up the leaf organ system. Various organ systems make up a full plant (an organism). |
Remember:
cells --> tissues --> organs --> organ systems --> organisms. |

|
As life processes go, this is the big one - respiration. Without it, you'd be well and truly stuck.
Respiration is a Chemical Reaction.
|
Respiration happens in energy cell of every living organism. It is the process of releasing energy from glucose (a sugar). |
|
|
The energy released by respiration is used for all the other chemical reactions that keep you alive. For example, the reactions involve: |
~ Building proteins
~ Muscle contraction
~ Keeping Warm |
|
|
Aerobic Respiration Needs Plenty Of Oxygen
|
1) Aerobic respiration is respiration using oxygen. It takes place in the mitochondria of animal and plant cells.
2) In aerobic respiration, glucose and oxygen react to produce carbon dioxide and water. This reaction released lots of energy. |
|
|
The word equation to show what happens in the reaction : |
glucose + oxygen --> carbon dioxide + water + ENERGY |
|
|
Anaerobic Respiration Needs Plenty Of Oxygen |
1) Anaerobic respiration is respiration without oxygen.
2) Anaerobic respiration is less efficient than aerobic respiration, so it releases less energy.
3)Because of this, anaerobic respiration usually only happens when cells can't get enough oxygen. |
