Here are the key findings from the investigation.

Visit Scotland's concerns include possible changes to open sky agreements, which "could adversely affect the ability of visitors to travel to Scotland".

Historic Environment Scotland has number crunched the impact a post-Brexit recession might have on its revenue and considered how that could be offset by a ticket price increase.

The National Galleries are mindful that "changes in regulation could bring extra bureaucracy and cost making it more difficult, for example, to mount international exhibitions".

As well as considering potential Brexit downsides, the National Library sees a possible upside: "renewed interest in Scottish literature, culture and events to support tourism" if Scotland's identity is repositioned on the world stage.

SCDI's Matt Lancashire warns the SMEs do not have the resources or time to scenario-plan going forward.

Chris Yarsley from the Freight Transport Association says because we don't know what we are planning for, "it's impossible to plan for it".

The legislation on allowing people from the EU to stay in the UK has not been brought forward yet and we need that legal certainty, he argues.

Jennifer Hunter from Culture Counts says the uncertainty is likely to be impacting bookings, because visas and other associated costs are unclear.

However, she caveats this with the fact it is difficult to collect data on the reasons why UK acts are not being booked.

NHS Lanarkshire has warned there is a "very high" risk it will not be operationally ready for Brexit leading to possible disruption of healthcare services.

The board said it was working with the Scottish government to identify and overcome problems.

Across the health service, there are concerns about access to specialist medicines, equipment and doctors after EU withdrawal.

A paper for the board of NHS national services Scotland raised a concern that Brexit could end UK membership of the European Blood Alliance (EBA).

This could result in "loss of early visibility on emerging infectious diseases" and force a Scottish blood expert to come off the EBA's executive board, the paper said.

Paul Buckley from the GMC says around 6% of doctors in Scotland are from the European Economic Area.

Rural health boards and specialist areas are most likely to be impacted by issues with future supply of doctors, he adds.

Tory MSP Alexander Stewart wonders about contingency plans.

Mr Buckley says the GMC's advice to the UK government has been to maintain supply as much as possible in whatever scenario.

We believe it would be important for the GMC to be able to recognise EU qualifications without having to put them through the "laborious" process which doctors from elsewhere have to go through, he explains.

Alistair Sim of Universities Scotland agrees uncertainty has caused the biggest problem.

The mobility of talent and ideas is essential to universities, he explains.

So far universities have continued with recruiting EU staff and students and applying for European research funds, Mr Sim states.

The real concern is what comes next and how our participation in research networks will continue, says the Universities Scotland director.

The sooner we know what the future will look like, the better, he adds.

Convener Joan McAlpine kicks off with a question on the impact of Brexit on each organisations' sector.

NFU Scotland's Clare Slipper says that the preferred option would have been to stay in the EU and the ongoing uncertainty around Brexit has been very damaging.

Matt Lancashire from SCDI agrees the "unknown" about what is coming has created instability.

We've seen people delay, postpone and cancel plans to scale up, which has an impact on the Scottish economy he adds.

This must be tackled soon to ensure Scotland remains competitive, Mr Lancashire adds.
