Anatomy of Flowering Plants

Transport of food material in higher plants takes place through
1 Sieve elements
2 Companion cells
3 Transfusion cells
4 Tracheids
Explanation:
Exp:A Transport of food material in higher plants takes place through sieve elements. They are specialized cells that are important for the function of phloem which is highly organized tissue that transports organic compounds made during photosynthesis. - The phloem also conducts some other substances such as amino acids. The conducting cells of the phloem are cylindrical cells called sieve tubes, which have sieve like partitions at both ends. - These partitions are known as sieve plates.

Which of the following tissues consist of living cells?
1 Vessels
2 Tracheids
3 Companion cell
4 Sclerenchyma
Explanation:
Exp:C Companion cells are present between sieve tubes in the phloem of angiosperm. These are the living cells with large nucleus that controls the activity of nonnucleated sieve tubes. Companion cells function to load and unload sugars into the cavity of sieve tube members.

Vascular tissues in flowering plants develop from
1 phellogen
2 plerome
3 periblem
4 dermatogen
Explanation:
Exp:B Plerome is the central histogen which forms stele or part of stem and root inner to endodermis. Part of plerome the forms vascular tissues is called procambium. Plerome represent the inner region of the apical meristem. It consists of thin-walled cells that serve as precursors for stele including the pith.

Closely and compactly arranged fundamental tissue is not found in
1 Prothallus of Pteris
2 Medulla of dicot stem
3 Columella of Funaria
4 Adaxial Mesophyll of Nerium
Explanation:
Exp:B Pith (Medulla) of dicot stem occupies the large central part of the dicot stem. It comprises thin walled parenchyma cell with inter cellular air space. Prothallus of Pteris - Prothallus of pteris is a single layered cellular structure having rhizomes at its ventral surface of the thalloid body. Columella of Funaria - Columella is the middle region consisting of parenchyma cell. It is found within the sporangium it act as a conducting tissue. Adaxial Mesophyll of Nerium - Both the adaxial and abaxial epidermis in nerium are multiseriate, being composed of up to three layers of compactly arranged cell with heavily cutinized outer walls.
