9.1 Transport in the Xylem of Plants

9.1 transport in the xylem of plants from Bob Smullen

Fantastic animated tutorials from McGraw Hill Education – Water Uptake, Mineral Uptake and here’s a simple transpiration animation.

A 13m 43s video lesson covering all of 9.1 from Dan Rott:

Paul Andersen explains how nutrients and water are transported in plants in Plant Nutrition & Transport.

PRESCRIBED PRACTICAL 7 – Transpiration rate using potometer

Measurement of transpiration rates using potometers

Plant experiments – notes from BioNinja

Simulations: Transpiration, a LabBench Activity from Pearson; Plant Transpiration, a Virtual Lab from McGraw-Hill Biology includes a quiz and a table of results to complete; Plant Transpiration virtual lab at Wow Biolab, includes a lab report to complete; Measuring Transpiration in Plants, a practical simulation from the University of Reading

Here’s a great animation in which you can change the factors that affect the rate of transpiration.

9.4 Reproduction in Plants

9.4 plant reproduction from Bob Smullen

A 13m 18s video lesson covering all of 9.4 from Dan Rott:

An 18m video clip on plant reproduction from ‘The amazing lives of plants’ (MacGraw-Hill) – we do not need to know about double fertilisation though:

FERTILISATION

An animated, narrated tutorial on the life cycle of an angiosperm (which also includes a quiz from Sinauer Associates) and Double Fertilisation in Angiosperms (University of Kent & UCA). Both go into much more detail than you need (we don’t need to know about double fertilisation) but they are good.

POLLINATION

The beautiful tricks of flowers – a 14m TED-Ed talk from Jonathan Drori and here’s ‘The Beauty of Pollination’ from Louie Schwartzberg (TED):

In Crash Course Biology #38 – The Plants & The Bees: Plant Reproduction, Hank gets into the dirty details about vascular plant reproduction.

GERMINATION

Mung bean time-lapse of germination:

Also here are radish seeds germinating & sprouting roots & shoots (46s).

PHOTOPERIODISM

A fantastic animated tutorial from McGraw Hill Education on Phytochrome signalling.
