Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish
sattari [20]

Answer:

Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.

Explanation:

Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.

According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.

Photosynthesis and cellular respiration, look at the picture
Anika [276]

Mike discovered that the  product of cellular respiration are the raw materials  of Photosynthesis while the products of photosynthesis  served as the raw materials for cellular respiration.

He also discovered that respiration is a catabolic process while photosynthesis is an anabolic process.

Another interesting fact seen by Mike is, the respiration releases energy while photosynthesis takes in energy.

Explanation:

  • In the equation of cellular respiration , we can see that glucose and oxygen are utilized in the mitochondrion to produce  carbon dioxide , water and chemical energy in the form of ATP.
  • Glucose breaks down during cellular respiration .
  • Again if we look at the chemical equation for photosynthesis in the chloroplast, we find that Carbon dioxide,which was produced during respiration is utilized along with water in presence of light energy to give out oxygen and Sugar (glucose)
