Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.

   C02         +          H20           →                   C6H1206    +       O2+           H20.

(carbondioxide) +    (Water)     Chlorophyll      (glucose)  +(oxygen)+     (water)

                                                       and                                                                                            

                                                   enzymes .                    

This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.

The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is  the source of oxygen seen above.

             4 H20→ 4H+ + 4e- + 02.

The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.

Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.

B.

The cell wall  of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .

<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains,  monomers of  glucose in small units  linked to one another by bonds.

C

Vacuole helps in plant turgidity needed for uprightness. when filled with water provides  turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity  helps the plants  to maintain resistance to external pressure and therefore resist the effects of gravity.

Your body contains tens of thousands of different proteins, each with a specific structure and function. The unique three-dimens
valkas [14]

Answer:

Each protein with a specific structure and function

The unique three dimensional shape of proteins is based on several superimposed levels of structure

Explanation:

Proteins are essential nutrients for human and a vital source of fuel for building body tissues. They are made up of amino acids linked together by peptide bonds. These amino acids act as precursor to nucleic acids, hormones, immune, repair of tissues among others.

Proteins contain 20 amino acids which are the building block for proteins. These amino acids can be reformed to create millions of protein in human body in which each protein has specific structure and function.

The three dimensional arrangement of atoms in an amino acid chain is know as the protein structure. The precise shape formed determine the protein function.

Semenov [28]

Answer:

Cells from the cheek are a type of epithelial cell, similar to skin. ... They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.
