The answer is chloroplasts
Answer:
E. All of the above
Explanation:
The cell cycle refers to the orderly series of events that make new daughter cells by dividing the existing cells. The cell cycle is required to produce new cells during growth and development, to replace the old and damaged cells, and to repair the tissue by adding the new cells. If the existing cells do not enter the cell cycle, new cells would not be formed to be added to the tissues of the organisms.
However, the cell cycle is regulated at several checkpoints to ensure that a cell enters the process only when the new cells are required by the body and the process is stopped once the required number of new cells are formed. Any deviation from the regulation of the cell cycle may make the cells to enter the uncontrolled cell division. It may even lead to cancer where the cells divide without any control and produce malignant tumors.
Answer:
a. F. W. Went isolated the chemical substance responsible for
communicating stimulus information- TRUE
b. The chemical substance responsible for communicating stimulus
information is a hormone- TRUE
c.Charles and Francis Darwin confirmed that the tip of a plant stem is
responsible for initiating the phototropic response- TRUE
d.When the tip of a stem is covered with a transparent cap, the stem bends
toward the light source anyway- TRUE
e. When the base of a stem is covered with an opaque shield, the stem
bends away from the light source- FALSE
f. An example of another control mechanism is that some plants require
more than 12 hours of darkness to produce flowers- TRUE
A. the products of photosynthesis serve as the reactants and cellular respiration to provide chemical energy.
Because photosynthesis produces oxygen and cellular respiration needs that oxygen to produce energy and carbon dioxide, the carbon dioxide is used to create energy and oxygen for the plant.
