Question 1:(a)Are xylem vessels living or dead structures? Give a reason for your answer.(b)What is the main function of the xylem vessel? State three structural adaptations of the xylem vessels and their functions.(c) How are the adaptations in the roots of plants similar to the ...
Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions of the xylem and phloem. Xylem helps in conducting water and mineral

Tracheids are nonliving cells found in the xylem of the more ancient plant types, seedless vascular plants (ferns, club mosses, and horsetails) and gymnosperms
What are end walls of xylem and phloem? How are cells in the epidermal tissue adapted? What is Aorta ? If we need nitrogen for our muscles and DNA, why doesn't our body absorb the nitrogen we breathe in? What is the common byproduct for cellular respiration and photosynthesis?
Mushroom reproduction can occur in a number of ways. Mushrooms can reproduce both sexually and asexually through the production of spores. Mushrooms may fragment or break off and form new offspring. Additionally, the hyphae of two mushrooms may fuse in sexual reproduction and form an offspring. ...
Which plant cells are dead at maturity, although still providing some useful function? a. Dermal b. Ground c. Xylem d. Phloem e. Lateral meristems Ferns and horsetails are ___ plants. a. flowering b. nonvascular c. seedless vascular d. seed-bearing v...
TDIF peptide derived from CLE41 or CLE44 is perceived by PHLOEM INTERCALATED WITH XYLEM (PXY), an LRR-RLK [21-24]. A group of Arabidopsis CLE-related peptides were identified via different searching strategies. These pep- tides are expressed in the root meristem region and are responsible ...
Xylem is a complex tissue that performs the function of transport of water or sap inside the plant. Xylem made up of three types of dead cells (vessels, tracheids, xylem fibres) and xylem parenchyma that is the living component.
Cork cambium and vascular cambium are: (a) parts of secondary xylem and phloem. (b) parts of pericycle. (c) lateral meristem. (d) apical meristem.Which of the following is considered part of a plant's vascular tissue? a. Cork cambium b.Cortex c...
