TRANSPORT IN PLANTS

The only living cells in xylem tissue are

• Xylem sclerenchyma

• Xylem tracheids

• Xylem vessels

• Xylem parenchyma

Raisins swell when put in

• Saline water

• Saturated sugar solution

• Rain water

• Coconut oil

The movement of molecules from their lower concentration to a higher concentration with the help of energy

• Diffusion

• Active transport

• Osmosis

• Brownian movement

The rate of transpiration decreases with an increase in

• Sunlight

• Temperature

• Humidity

• Wind

The inorganic nutrient that is involved in the opening and closing of stomata

• Iron

• Phosphorus

• Potassium

• Nitrogen

The food synthesised in the plants is transported through phloem in the form of

• Sucrose

• Starch

• Glucose

• Fats

Conducting cells in phloem are

• Phloem parenchyma

• Sieve tubes

• Companion cells

• Phloem fibres

Most of the water gets evaporated from the plants from its

• Flowers

• Stem

• Roots

• Leaves

If pure water is separated from a strong sugar solution by a semi permeable membrane, then the net movement of molecules is

• From pure water to the sugar solution

• From sugar solution to pure water

• No net movement

• Equal movement of molecules In both directions

Ascent of sap takes place through

• Phloem

• Epidermis

• Cortex

• Xylem
