Dear David Hershey,

Is parthenocarpy in plants synonymous to parthenogenesis in animals?

Are the pineapples of same variety grown in the fields which produces seedless 
fruits homozygous (pure breed)?
If it is, would the seedless nature of the fruit has something to do with 
inbreeding depression or something else?

The seed produced by cross pollinating different variety of pineapple is 
heterozygous (hybrid).  When the resulting heterozygous seed grows into a 
mature plant, would it produced a seeded fruit?

How is plant tissue culture done?
Would any tissue of the plant be a viable candidate or only a selected tissue 
of the plant?

P.S. What is difference between botany and agriculture?
