There are a lot of possible reasons: the plant did not get mature enough to produce female flowers; or there was insufficient pollination of the female flowers; or there was a pest which ate the new zucchinis, etc.
Any kind of plant that can produce glucose and oxygen in photosynthesis.

A fruit plant that does not produce any fruit.

A non-bearing fruit plant is a plant that does not produce edible fruits. These plants may still produce flowers but do not develop into fruits that can be consumed. Examples include ornamental flowers like hyacinths or plants grown for their foliage like coleus.
A female marijuana plant does not produce any seeds, unless it is polinated by a male plant. Once the plant is pollinated there is not set number of seeds that are produce, but there will be a lot depending on the amount of pollinations.
The tall plant must be heterozygous.
A plant... specifically a flowering plant Any chlorophyll-bearing plant is able to produce nourishment for itself through photosynthesis. Broccoli is one good example of a chlorophyll-bearing plant (as is any green plant.)
I do have to point out that the male plant doesn't produce seeds. It pollinates, which is what ultimately makes the female plant produce seeds. you would need a female plant to get any seeds at all.
