Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
When food is eaten it is digested by converting it into smaller particles. These smaller particles are than digest and gives the energy to our body. The energy which produced is just come from our food on this base we can say that mass neither created nor destroyed but it change one form to another, just like the form from food to energy.
Another example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
both are single cells that carry out the functions of life
Explanation:
Both eukaryotic and prokaryotic cells are single cells according to the cell theory and they carry out the functions of life.
- The cell theory postulates that all living organisms are made up of cells and that the cells are the basic organizational unit of life.
- It also proposes that all cells arise from pre-existing cells.
Eukaryotic cells differs from prokaryotic cells in that they have true nucleus and membrane bound organelles.
Despite this seeming different, both cells are able to carryout different life functions as unit and when they combine together, they advance into higher organization of life.
