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
