A vector is an organism that can carry pathogen(= disease causing organism) from infected plant to a health plant. Generally, a vector is an insect, a nematode, a fungi, or insect like organisms e.g. spider mites. To qualify as vector, the organism must have the ability to acquire the pathogen, must be able to retain the pathogen for some length of time and lastly it must be able to inject it into a suitable/susceptible plant. The relationships between the vector and pathogen can be described as simple if the pathogen does not circulate or replicate in the vector or complex if the pathogen replicates or circulate in the vector. In the latter case, the vector also acts as the host of the pathogen.

Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal to the zero vector?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
What is relationship between vector space and vector subspace?
Vector spaces can be formed of vector subspaces.
Vector that shows the combined effect of two or more vector?
Resultant vector or effective vector
What is resolution of vector?
Spliting up of vector into its rectangular components is called resolution of vector

What are three major areas of plant science?
Three major areas of plant science are plant physiology, plant genetics and breeding, and plant pathology. Plant physiology studies how plants function and respond to their environment, while plant genetics and breeding focus on improving plant traits through selective breeding. Plant pathology deals with the study of plant diseases and their management.
