Vascular plants, also known as tracheophytes or higher plants, are a large group of plants have lignified tissues (the xylem) and non-lignified tissue (the phloem). Vascular plants include the clubmosses, horsetails, ferns, gymnosperms and angiosperms....
(a) Primary phloem (b) Secondary pholem (c) Secondary xylem (d) Primary xylem View Solution Assertion :- Old woody plant parts are devoid of primary phloem. Reason :- Primary phloem gets crushed due to continuous formation and accumulation of secondary xylem. ...

The xylem ( sapwood)layer that is under the phloem allows water to be carried from the roots up to the top of the tree. New sapwood is produced each year. The neat thing about the old sapwood is that it makes a ring inside the tree each year. You can count these rings to find ...
What is the difference between pre tRNA and mRNA? What is the difference between homologous chromosomes and a homologous chromosome pair? How do the structural differences in the xylem and phloem reflect differences in function of the two types of vascular tissue? What is the difference between a...
Phloem is a type of plant tissue. Along with its counterpart, xylem, phloem allows plants to...
Leaves and bark, xylem and phloem, and cambium. What are those made of? Cells, molecules,carbonatoms. But what's an atom made of? Whatismatter, really? Matter is defined as that which 1) has mass and 2) has volume or takes up space. Mass is an intrinsic property whose base SI unit...
Phloem and xylem range from two to four. Conjunctive tissue is a layer of parenchymatous cells surrounding the xylem and phloem. The pericycle, consisting of several layers of thick-walled parenchyma cells, comes after the endodermis. Dicots lack a clear central pith. ...
The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specialization, cell heterogeneity, and diverse cell comp...
Meristem is the tissue that continues to divide and differentiate to produce tissues and organs. They are present on root and shoot tips and in between the xylem and phloem. Answer and Explanation:1 Pericycle arises from theprocambium. Procambium is a meristematic tissue and gives rise to the...
