Why are some simple plants only found in damp places. Why are flowering plants the most successful on this planet. What is the difference between reproduction in coniferous plants and in flowering plants.
This solution sets out to put in plain english some of the intricacies and complicated vocabulary used in Botany.
This question has a lot to do with the evolution/ development of different plant species.
Think of the algae, mosses, ferns as being simple (non seed producing) plants and conifers and flowering plants as being seed bearing plants. The latter more advanced than the former.
The first three are limited in their ability to colonise all areas at some stage in their development they are truly water bound,(all due to alternation of generations between different phases in their life cycle but that is another story)and therefore in biological terms cannot be considered truly successful.
Gymmnosperms i.e Conifers and Angiosperms i.e flowering plants, are considered much more advanced plants. A seed is quite an advancement on spores in terms of complexity, survival adaptation etc.
Gymnosperms are said to have naked, exposed seeds and Angiosperms develop seeds within a developed ovary that biologists call a fruit.
To manage to break free from water dependence plants evolved a number of strategies over millions of years.
