HomeArticles, FAQWhat keeps phloem alive?

Phloem consists of living cells. The cells that make up the phloem are adapted to their function: Each sieve tube has a perforated end so its cytoplasm connects one cell to the next.

Q. How do xylem and phloem work together?

Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.

Q. What does phloem do in a plant?

Phloem is the vascular plant tissue responsible for the transport and distribution of sugars produced by the photosynthesis.

Q. What is the function of a Xylem?

Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Q. What is the main difference between xylem and phloem?

Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.

Q. What cells of phloem are dead?

The four types of phloem cells are: sieve tube cells , companion cells, fibers (the only dead cells in phloem), and parenchyma.

Q. How does the phloem work?

The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’.

Q. Which tissue is always absent in roots?

Generally, parenchyma tissue is found in leaves, stems, and roots. When parenchyma holds chloroplast is known as collenchyma which is absent in roots rather than it can be located more in leaves and stems as it produces chlorophyll and helps in photosynthesis.

Q. Is xylem present in Roots?

The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.

Q. What is the purpose chloroplast?

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids.
