Answer:
To examine the importance of light to a plant's growth.
Explanation:
To give a background to this question, I will define a key term "Photosynthesis". Photosynthesis is a compound word made up of photo (which means "light") and synthesis (which means "to put together").
It is the process by green plants use sunlight to obtain nutrients from carbon dioxide and water.
The experiment us meant to examine the effect of deprivation of sunlight on a plant's growth.<u> </u>
Therefore, the essence of keeping one set of seedlings in the light is to compare if there is any difference in growth between the seeding kept in the dark cupboard and that kept in the light.
This enables us to conclude whether or not light is important for the growth of a plant.
NUCLEUS IS CALLED CONTROL CENTRE OF THE CELL BECAUSE IT PERFORMS TWO MAIN PRINCIPAL FUNCTIONS:
1. Contains genetic information for structure, reproduction , development, metabolism and behaviour. ...
2 Controls cellular activities through directing synthesis of particular proteins and enzymes.
Explanation:
It contains the genetic instructions for every function of the cell. It is the cell's powerhouse and processes energy for the cell. It is responsible for packaging proteins for delivery out of the cells.
Chemotaxis is movement of a motile cell or organism, or part of one, in a direction corresponding to a gradient of increasing or decreasing concentration of a particular substance.
Green plants are considered producers because they directly absorb sunlight to make energy :)
Oh man i remember learning about this but i cant remember what the answer is i will see what I can do :D
