2. Growth of shoot system
3. Growth of root system
4. Growth towards water

‘B’
a. Gravitropic movement
b. Chemotropic movement
c. Phototropic movement
d. Growth-irrelevant movement
e. Hydrotropic movement

Answer 1

Hey.....

1.---->(b). {growth of pollen tube toward ovule ----chemotrophic movement}.

2.---->(c).{growth of shoot system---phototrophic movement}.

3.---->(a){growth of root system---gravitropic movement}.

4.----->(e){growth towards water----Hydrotropic movement}......

Hope this will help u...

Answer 2

The correct match will be:

Explanation:

• 1. Growth of pollen tube toward ovule → (b) chemotrophic movement.
• Chemotropism isrefers to the growth of plant navigated by chemical stimulus from outside of the plant.
• 2. Growth of shoot system → (c) phototrophic movement
• Phototropism refers to the growth of a plant in response to a light stimulus.
• 3. Growth of root system → (a) gravitropic movement
• Gravitropism refers to the growth of a plant in response to gravity pulling on it.
• 4. Growth towards water → (e) Hydrotropic movement
• Hydrotropism refres to the growth of plant in response to the direction determined by a stimulus or gradient in water concentration.
