The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

Conifer Leaf.  

Microphyll Leaf.  

Megaphyll Leaf.

A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

leva [86]

If there was a dramatic increase in skeletal muscle cell damage and apoptosis, I would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.

<h3>What does high CK-MB mean?</h3>

Elevated CKMB can be a sign of cardiac (heart muscle) damage or chronic kidney failure. At the onset of acute symptoms, after cardiac peaks, CKMB values ​​are elevated after 3-6 peaks after 12-24 hours between 12-24 hours, values ​​at 24-48-48.

With this information, we can conclude that if there was a dramatic increase in skeletal muscle cell damage and apoptosis, we would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.
