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 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.
6.6 Hormones, Homeostasis & Reproduction
BioKnowledgy presentation on 6.6 hormones homeostasis and reproduction from Chris Paine
6.6 Hormones, Homeo & Repro notes to complete (created by Mrs Green).
IB Biology 6.6 notes – Cheryl Haus talks us through the topic while making notes in a 1 hour video.
Some past paper questions answered by IB Blueprint: Nerves, hormones and homeostasis – Paper 1 Questions ; Nerves, hormones and homeostasis – Paper 2; Reproduction – Paper 1 Questions; Reproduction – Paper 2 Questions.
HORMONES
