What are the living elements of xylem and phloem?
Answer : Living element of xylem: Xylem parenchyma. Living elements of phloem: Sieve tubes, companion cells, and phloem parenchyma.
How many elements of phloem are living?
Living elements of phloem are sieve tubes, companion cells and phloem parenchyma.
How many elements of xylem are living?
There are four different kinds of elements which come under the xylem which includes: vessels, tracheids, xylem sclerenchyma and xylem parenchyma.
Which is the living elements of xylem?
Complete answer: The living component of xylem is the xylem parenchyma.
Which of the following are living elements?
The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N).
Which cells of phloem are living?
Phloem companion cells are parenchymatous and these have a nucleus. These are also the living cells of phloem. Phloem fibers are dead.
Is xylem a living tissue?
Except for Xylem parenchyma, all Xylem components are dead, making xylem a non-living tissue. The primary function of Xylem is water conduction.
Does xylem have living cells?
The xylem transports water and minerals from the roots up the plant stem and into the leaves. Lose their end walls so the xylem forms a continuous, hollow tube. Become strengthened by a chemical called lignin . The cells are no longer alive.
Which one is non-living in phloem?
The non-living components of the phloem are the sclerenchymatous cells. Explanation: Phloem can be described as the vascular tissue in the plants whose main function is to transport food from the leaves to all parts of the plant.
Which part of phloem is non-living?
The phloem is composed of sieve tubes, companion cells, phloem parenchyma and fibres. The fibres are the dead sclerenchymatous cells in the phloem responsible for mechanical support. These cells are considered as non-living component of phloem.
What 4 elements are in all living things?
Carbon, hydrogen, oxygen, and nitrogen are the most important elements. Small quantities of other elements are necessary for life. Carbon is the most abundant element in living matter.
Is xylem a living cell?
Xylem is the complex tissue of plants, responsible for transporting water and other nutrients to the plants. Xylem consists of dead cells (parenchyma is the only living cells present in the xylem). Pholem mainly contains living cells (fibres are the only dead cells in the phloem).
