Do plants that do not reproduce bby seeds have flowers? ie. Begonia, banana, pineapple, Bryophyllum...?

do ALL those types of plants flower?





Also, does heat travel faster through liquids, gases or solids?





will water evaporate in a refrigerator?

Bananas have seeds - it is that black line thru the center. They have flowers - it is how they are fertilised to produce fruit. Plants that reproduce by means other than seeds (the banana is a trick question!) don't need flowers, the 'earlier' evolutionary path items such as ferns, fungi, etc have other means. Bananas have apparently 'evolved' to the extent that they reproduce by tuber - or shoot - one conjecture was that it had something to do with mankind cultivating them!





Heat travels thru solids by conduction, thru liquids by convection, and thru gases by convection, and sometimes radiation. As to 'faster - well conduction thru a solid is often faster due to the 'conduction properties of some solids being better than others, for instance a silver rod will conduct heat more readily than a chunk of mica, or ceramics (Space Shuttle heat shield tiles!). Gases and liquids may conduct heat better than thru stuff like mica or ceramics - which are a heat insulators.





Water will 'sublime' in a fridge or freezer - go directly from solid to gas - and you do NOT need a fan.
Reply:Plants that don't reproduce by seed are Ferns and fungi, which reproduce by spores.





Begonias flower, bananas flower, pineapple is the flower.





Water is the most conductive, next to copper which would be a solid.





Yes, over time water will evaporate in the fridge.
Reply:tubers, gasses,yea, there is a fan in the frig
Reply:ad plant part of question ...





This is a little confused question.


Begonia, banana, pineapple and Bryophyllum, all of them generally can reproduce by seeds. And of course, all flower.


Yes, there are some species of these plant, mostly planted for agricultural or ornamental purposes, which are not propagated by seeds from various reasons. But their close relatives always have viable seeds.


Seed plants, ie. flowering plants, conifers, cycads, ginkgos and gnetophyta are defined (and named) as "having seeds". There are some rare exceptions, for example some opuntias, which are not able have seeds and they are reproduced only vegetatively. But all of these cases are young, propably short-term and their close relatives always have seeds.


And for johnknow %26amp; reynwate: Fungi ARE NOT plants, this is only posthumous child of old and/or bad schoolbooks. In fact, fungi are close relatives of animals and we share with fungi a lot of interesting characteristics, e.g. type of flagellum.
Reply:those are flowering plants


yes they produce flowers
