<span>This is a great question and I would love to hear what a roller coaster designer / engineer thinks makes a successful roller coaster. Until they show up, though, you've just got me.For me a successful roller coaster is one that fills me with dread as it makes the slow climb up the track, and then converts that dread into pure adrenaline as it takes me down and around. It's the one that makes your stomach drop as you're in freefall and makes your heart skip a beat as you take a corkscrew loop. Some roller coasters are open at the bottom so your legs dangle off. Some go backwards through a corkscrew. Those are fun additions.What I'm saying is that a good roller coaster is one that floods you with emotions as you're riding it - think about the Mummy ride at Universal Studios. It's not a particularly crazy coaster as far as thrill rides go, but the design of the ride itself is meant to fill you with anxious dread as you wait for something to happen and then launches you at breakneck speed when you least expect it. That's a good roller coaster, and I'm not even sure you'd actually call it a roller coaster.Well that's me ^.^ I hope this helps</span>

The sporophyte of <u>whisk ferns</u> consists of evenly forking photosynthetic stems that lack roots and leaves.
Whisk ferns are the elementary and simplest vascular plants.
They contain small-sized protuberances which are called ' enations.'
In these plants, a vascular system is present in the center through which the transport of nutrients and other fluids takes place.
Moreover, roots and leaves are absent in these plants and are composed of forklike stems.
To put it simply, these plants have hair-like structures that are part of the rhizomes. These structures are called rhizoids.
