Living organisms, by definition are conscious, so plants can rightly be considered conscious.
That is not true. Living organisms with a nervous system exhibits conscious states but those without simply are reactionary in their processes. IE sunlight causes plants to grow.
This is a completely fundamentalist scientific viewpoint and is the only one that can be rationally concluded at the moment.
Believe me I have pondered whether
I'm not certain that a nervous system is a prerequisite for consciousness...
What about jellyfish? They don't have a brain or a central nervous system* yet most would consider jellyfish conscious.
(*while the jellyfish has no brain or central nervous system it has a loose "nerve net" )
My opinion is that all living forms posses some level of consciousness...and it's a higher level of consciousness than we give plants credit for.
This is incredibly difficult for most people to wrap their heads around, and if one only has a very rudimentary background knowledge of plant biology and plant functioning, and even more important, if one has a rudimentary view of what consciousness is, these concepts will seem absurd.
Animals communicate through behaviors, plants communicate through chemistry...
(People often assume that all compounds produced by plants are as poisons, while this is not the case, plants produce just as many compounds to attract life-forms as they do to repel them.
In the link above the wild tobacco plant dedicates loads of energy towards producing specific chemical compounds, when being destroyed by a certain larva they can release this compound in the form of a trichome, the larva eats the trichomes and the hidden chemical weapon in them, when the larva eat this chemical, they emit a smell attracting predator birds which eat them, this plant can also switch is pollinators in a very complex and intentional manner.
Nicotinia attenuata, a type of wild US tobacco, is usually pollinated by hawkmoths. To lure them in, it opens its flowers at night and releases alluring chemicals. But pollinating hawkmoths often lay their eggs on the plants they visit and the voracious caterpillars start eating the plants. Fortunately for the plant, it has a back-up plan. It stops producing its moth-attracting chemicals and starts opening its flowers during the day instead. This simple change of timing opens its nectar stores to a very different pollinator that has no interest in eating it – the black-chinned hummingbird.
Danny Kessler from the Max Planck Institute first noticed the tobacco plant’s partner-swapping antics by watching a population of flowers that was overrun by hawkmoth caterpillars. Nearly every plant was infested. To Kessler’s surprise, around one in six flowers started opening between 6 and 10am, rather than their normal business hours of 6 and 10pm. To see if the two trends were related, Kessley deliberately infested plants from another population with young hawkmoth larvae.
The plant is obviously conscious of its surroundings, and of the parasites and pollinators surrounding it, they are aware of the chemical conditions around them as well as environmental conditions.
Stefano Mancuso founded something called "the study of plant neurobiology"
From his laboratory near Florence, Mancuso and his team explore how plants communicate, or "signal," with each other, using a complex internal analysis system to find nutrients, spread their species and even defend themselves against predators. Their research continues to transform our view of plants from simple organisms to complex ecological structures and communities that can gather, process and -- most incredibly -- share important information.

Plant roots behave like foraging animals (watch the 7 minute clip in the link above)
ecologist James Cahill describes how root growth in plants follows patterns similar to those of animal foraging, how plants identify and select their food sources in the first place, and what that selection suggests about their level of behavior.
