Forces in Ascent of Sap Quiz

What is the process by which water is pulled up from the roots to the leaves of a plant?

• Transpiration

• Photosynthesis

• Respiration

• Capillary action

Which subtopic explains the movement of water through narrow tubes in the plant?

• Transpiration

• Pollination

• Respiration

• Photosynthesis

What is the force that helps in the movement of water against gravity in plants?

• Adhesion-compression

• Repulsion-pressure

• Cohesion-tension

• Tension-cohesion

What is the significance of cohesion in the ascent of sap?

• Cohesion causes the plant to absorb more carbon dioxide

• Water molecules are able to move upwards through the plant's xylem vessels due to cohesion.

• Cohesion helps the plant to produce more flowers

• Cohesion allows the plant to grow taller

How does capillary action contribute to the ascent of sap in plants?

• Capillary action allows water to move upwards through narrow tubes or spaces, such as the xylem vessels in plants.

• Capillary action only works in artificial materials and not in plants

• Capillary action has no effect on the movement of water in plants

• Capillary action causes water to move downwards in plants

What is the role of root pressure in the movement of water in plants?

• It has no role in the movement of water in plants.

• It causes water to move sideways within the plant.

• It helps to pull water down from the leaves to the roots.

• It helps to push water up from the roots to the rest of the plant.

Which part of the plant is primarily responsible for the ascent of sap?

• Roots

• Flowers

• Xylem

• Leaves

What is the structure in plants that facilitates the movement of water from roots to leaves?

• chloroplasts

• xylem

• phloem

• stomata

How does transpiration pull contribute to the ascent of sap in plants?

• Transpiration pull pushes the water down from the leaves to the roots

• Transpiration pull causes the water to move sideways within the plant

• Transpiration pull creates a negative pressure in the leaf, which pulls the water up from the roots through the xylem vessels.

• Transpiration pull has no effect on the movement of water in plants
