Photosynthesis Puzzle #3

Radda [10]

Answer:

They all have cholorophyll

Explanation:

Or we can say they carry out photodynthesis and make food.

See, all the pictures are green, this green pigment (colour ) is cholorophyll.

The first, second and fourth are pictures of leaves [which makes food] and the third picture is a illustration of the mitochondria.

For energy, a plant breaks apart some of the small sugars it builds. What does the plant do with the rest of its small sugars?

balandron [24]

Answer:

The plant stores them as starch

Explanation:

A typical plant synthesizes sugars from photosynthesis by using water and carbon dioxide.

$6CO_2 + 6H_20 + energy --> C_6H_1_2O_6 + 6O_2$

Parts of the sugar synthesized via photosynthesis is used to generate energy during respiration. The energy generated is useful for other metabolic processes in the plant's body.

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_20 + energy$

<em>The remaining sugar is utilized in the synthesis of starch and stored in the various tissues of the plant.</em>
