Question

Чем лист отличается от корня?

Answer 1

Строением ,функцией и организмом
Лист , орган высших растений, выполняющий функции фотосинтеза и транспирации, а также обеспечивающий газообмен с воздушной средой и участвующий в др. важнейших процессах жизнедеятельности растения. От других вегетативных органов высших растений — корня и стебля — Л. морфологически отличается обычно дорзовентральной (а не радиальной) симметрией, боковым положением и, как правило, ограниченным базальным ростом.

Answer 2

Difference between a Leaf and a Root

Leaves and roots are two essential parts of a plant, and they have distinct characteristics and functions. Here are the key differences between a leaf and a root:

Leaves: - Leaves are the main site of photosynthesis in plants, where they capture sunlight and convert it into energy. - They are typically flat and thin, with a large surface area to maximize sunlight absorption. - Leaves have chlorophyll, a pigment that gives them their green color and is crucial for photosynthesis. - They contain stomata, small openings on the leaf surface that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen. - Leaves also play a role in transpiration, the process by which plants lose water vapor through their stomata.

Roots: - Roots are usually located underground and serve as the anchor for the plant, providing stability and support. - Their primary function is to absorb water and nutrients from the soil, which are essential for the plant's growth and development. - Roots have root hairs, tiny extensions that increase the surface area for better absorption of water and minerals. - They also store food reserves, such as starch, that the plant can use during periods of limited nutrient availability. - Roots can vary in shape and structure depending on the plant species and its environment. Some roots, like taproots, are thick and long, while others, like fibrous roots, are thin and spread out.

In summary, leaves are responsible for photosynthesis and gas exchange, while roots primarily absorb water and nutrients from the soil. Both are vital for the overall health and functioning of a plant.
