Why leaves turn color

Leaves contain 3 types of pigments: chlorophyll which is green, carotene which is yellow, and anthocyanin which is red.

Chlorophyll make the leaves appear green because it absorbs Red and Blue light from the sunlight.
Carotene make the leaves appear yellow because it absorbs Blue-Green and Blue light from the sunlight.
Anthocyanin make the leaves appear red because it absorbs Blue-Green, Blue and Green light from the sunlight.

Chlorophyll are comparatively unstable and is continuously regenerated via sunlight and warm temperature. When climate gets colder and chlorophyll or green color decline, the more stable carotene the yellow pigments appear and leaves turn yellow. As the leaves dry, the increased level of sugar reacts with some proteins and sunlight to form anthocyanin the red pigment, making the leaves turn red. Anthocyanin are PH sensitive and it can be bright red in ripe apples or purple in ripe grapes.

You’re not you anymore

Did you know that our body replaces itself as often as in days?

We are not the same person we were yesterday. We tend to think this way and hang onto the past perhaps because our brain cells are one of the few cells that do not get replaced. The rest of our body is renewed as often as every single day and this is no less significant than our memories.

Stomach cells, for example, have life span of 2-9 days.
Red blood cells live 4 months.
Lungs, 8 days.
Tongue taste buds, 10 days.
Small intestine epithelium, 2-4 days.
Skin cells, 10-30 days.

We let go of the familiar things every second.
And we give birth to the new every second.

 

 

 

 

There are two

 

There are those that honor their parents,

And there are those that dishonor their parents.

 

There are those that value family,

And there are those that break the family.

 

There are those that know the past,

And there are those that don’t know the past.

 

There are those that know and respect themselves,

And there are those that face away and disregard themselves.

 

Our hearts are like the universe – no matter how many layers of clouds blind us from it, it will always be there.
