2. Need goggles on to write answer, the other person also writes the answer. 3. Person with goggles on first go to answer & get point
3. For every 2 questions the person on the left needs to move – everyone faces off with different partner.
4. The correct answer 1 point- points relate to prizes!
Aim of the game- answer questions right for a prize!
Question 1
What is Phototropism?
Phototropism is the plants response to light
Question 2
What is Abscission?
The natural release of leaves and fruit from a plant
Question 3
Name the 5 hormones in plants?
Auxins Gibberellins Cytokinins Abscisis Acid Ethylene
Question 4
What is Geotropism?
Plants response to gravity
Question 5
Where is Auxin produced?
The shoot tip - meristem
Question 6
What do cytokinins promote?
Cell Division & Differentiation
Question 7
What is senescence?
Aging
Question 8
Where is Ethylene produced?
Ripening fruits;flowers, seeds, leaves & roots.
Question 9
Explain/examples –ve & +ve geotropism?
Roots +ve & leaves –ve geotropism
Question 10
Where is Abscisic acid produced?
Chloroplasts
Question 10
Why are hormonal responses in plants slow compared to animals?
Fair distance from origin to the point of need/effect
Move through xylem (water) & phloem (food) or cell to cell
Question 11
What happens to the cells in a plant shoot when Auxins are released?
Elongate – this causes the tip to bend towards the light
Question 12
Give 1 example of how plants differ from animal hormones?
Plants have;
1. Fewer Hormones
2. Relatively simple hormones
3. Hormone (not in glands) produced
by cells receiving the stimulus
Question 13
What is apical dominance?
Apical dominance – the main stem suppresses growth of the side branches
Question 14
What is ABA?
Abscisic Acid
Question 15
Which hormone is responsible for fruit ripening?
Ethylene
Question 16
Ethylene production is triggered by which 2 hormones?
Auxin & Abscisic Acid
Question 17
Abscisic Acid controls stomata movement – why do these close in drought conditions?
To prevent water lose from plant (prevent dehydration)
Question 17
Abscisic Acid controls stomata movement – why do these close in drought conditions?
To prevent water lose from plant (prevent dehydration)
Question 18
This is an example of what?
Phototropism (+ve)
Question 19
Which hormone promotes growth of the entire plant?
Gibberellins
Question 20
Abscisic Acid’s actions are opposite to which hormone?
Auxin.
ABA is growth inhibitingAuxin growth promoting.
Question 21Which hormone is at play in the photo?
Gibberellins
Question 22Which hormone is at play in the photo?
Ethylene
Question 23
Which hormone is at play in the photo?
Auxin
Question 24Which hormone is at play in the photo?
Abscisic Acid ABA
Question 25Which hormone is at play in the photo?
Cytokinins
Remember; More Cytokinin than Auxin:leaves and stems developLess Cytokinin than Auxin:roots develop
