The answer is competition. Because it wants the other plants to move so it can have all of the space to grow.
Ans.
Cell-to-cell communication allows signalling of essential substances between the plant cells, which are surrounded by cell walls. The molecules used by plants for long-distance signalling are known as hormones, such as auxin, ethylene, and gibberelin.
These hormones are secreted by one plant cell and received by another plant cell, where it exerts it affect. Thus, the correct answer to be fill in the blank is 'option A). hormones.'

Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).
Chemicals produced by bacteria that limit the growth of other bacteria are called antibiotics.
