Transportation In Plants! Trivia Questions Quiz

Explanation
Plants use vascular tissues, specifically xylem and phloem, to transport essential substances throughout their structure. Xylem carries water and dissolved minerals from the roots to the leaves, supporting photosynthesis and overall plant hydration. Phloem distributes the sugars produced during photosynthesis from the leaves to other parts of the plant, providing energy and nutrients needed for growth, reproduction, and storage. This system ensures the plant's survival and development.

Explanation
Xylem is responsible for transporting water and minerals from the roots to the leaves. It flows in an upward and outward direction, against gravity, due to the cohesion and adhesion properties of water. Phloem, on the other hand, transports sugars and other organic molecules from the leaves to the rest of the plant. It usually flows in a downward direction, from the leaves to the roots, driven by osmotic pressure.

Explanation
Transpiration is the process by which plants lose water through evaporation from their leaves. This evaporation occurs through small openings called stomata, which are primarily found on the surface of leaves. Transpiration plays a crucial role in the movement of water within plants, as it creates a negative pressure gradient that helps to pull water up from the roots to the leaves. This process is known as the transpiration pull, and it is the main driving force behind water transport in plants.

Explanation
Transpiration is the process by which water is evaporated from the leaves of plants and released into the atmosphere. Cohesion refers to the attraction between water molecules, which allows them to stick together and form a continuous column of water in the plant's xylem vessels. Adhesion refers to the attraction between water molecules and the walls of the xylem vessels. These two factors, cohesion and adhesion, work together to facilitate the movement of water from the roots to the leaves of a plant during transpiration.

Explanation
Cohesion refers to the tendency of water molecules to stick to each other, which allows for the formation of water droplets and the movement of water in a continuous column. Adhesion, on the other hand, refers to the tendency of water molecules to stick to the walls of the xylem tubes, which helps in the transportation of water from the roots to the leaves of plants.

Explanation
Xylem is the fundamental tissue in plants responsible for the transport of water and minerals from the roots throughout the plant. This vascular tissue functions much like veins in animal systems, facilitating upward movement of water and dissolved substances, crucial for the plant's nutritional needs and overall hydration. This system enables not only growth but also supports photosynthetic activities by supplying necessary water to leaf cells.

Explanation
The source refers to the leaves or the stems where photosynthesis occurs. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The glucose produced in the source is then transported to other parts of the plant, where it is stored or used for energy. This process is known as translocation. The places in the plant where the sugars build up are referred to as sinks. Sinks can include fruits, roots, flowers, or any other part of the plant that requires energy or storage.
