Front

What characterizes RNA?

Back

RNA is characterized by a phosphate group, ribose sugar, and uracil.

Front

Why does water move from the roots to the leaves of plants?

Back

Water moves from the roots to the leaves due to capillary action, which pulls water molecules in a continuous chain.

Front

What is the specific heat of liquid water compared to other substances?

Back

Liquid water has a high specific heat compared to other substances.

Front

What properties of water explain its movement in plants?

Back

The movement of water in plants is explained by cohesion, adhesion, and transpiration.

Front

What is the key difference between DNA and RNA?

Back

The key difference is the presence of uracil in RNA, which is not found in DNA.

Front

Define cohesion in the context of water.

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding.

Front

Define adhesion in the context of water.

Back

Adhesion is the property of water molecules to stick to other substances, such as plant cell walls.

Front

What is transpiration in plants?

Back

Transpiration is the process of water vapor loss from plant leaves, which helps draw water up from the roots.

Front

What role does capillary action play in plants?

Back

Capillary action helps transport water from the roots to the leaves against gravity.

Front

What is the significance of ribose in RNA?

Back

Ribose is the sugar component of RNA, which distinguishes it from DNA that contains deoxyribose.
