I'm doing my project based on this eight criteria to a living or non-living organism.
M- Movement
E- Excretion
R-Respiration
I- Irritability
G- Growth
R- Reproduction
A- Adaptability
N- Nutrition
An organism is classified as "Living" or "Non-Living" based on the eight criteria and normally, an organism which possesses most of the criteria are classified as "Living" and organism which does not posses most of the criteria are classified as "Non-living". But vegetables respire and they do not move or excrete, so do we classify them as non-living things?
I'm writing about ...
Whether if nail e.g Finger nail, toe nail still attached to a living organism's body part is a living thing.
Nails are made up of tough protein called keratin
Keratin filaments in cells
Nail can grow and it needs nutrition to grow.
FACT :
- if a nail is dead, it can still regrow.
- Nails are being labeled into parts.
- Nails are like skin, they can be dried, infected, peel or break.
Maybe some of you might think that, the most important criteria for a living thing is to respire but i think the most important criteria is nutrition. Without nutrition, nothing can grow and you probably won't have the energy to respire.
Therefore, in my conclusion, I think nails are living things. Actually most of the living things around us seem dead, but if you look carefully and study them, you'll realized you're wrong.
