The student is actually doing replication

Answer: Option B

<u>Explanation:</u>

A student reads about a particular experiment, gets inquisitive to learn more and hence tries to copy that particular experiment. This is called as replication   as the student tries the same methodology and process adapted to perform the experiment. He tries to obtain the same result.

This result fascinates him giving assurance of the experiment. It also helps motivate trying different experiments.  It also inspires him to make further researches.

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.

Describe the movement of particles within solids, liquids, and gases.
Paladinen [302]
Particles in solids move ever so slightly. They are not completely at rest, but since they are so packed together it’s difficult for them to move. That’s what makes a solid a solid. Particles in liquids slide and move past each other fairly quickly, and have space to move. Particles in gases are the most spread apart, and because of this, they move the quickest. Hope this helped.
