The companion cells help in maintaining the pressure gradient in the sieve tubes. Lateral roots develop endogenously, i. Sclerenchyma is considered thick-walled lignified supportive tissue characterized by the absence of living protoplast.
Collenchyma provides mechanical strength; along with flexibility to certain plant parts, like stalk of a leaf.
There are two main types of tissue found in plants- meristematic tissue and permanent tissue. Phloem- It consists of four of elements: These fibers are called as bast fibers OJEE Both apical meristems and intercalary meristems are primary meristems because they appear early in life of a plant and contribute to the formation of the primary plant body.
The tissue derived from the procambium is called the vascular or fascicular tissue system. For Example, in roots. They lack sieve tubes and companion cells.
Quiescent center The quiescent center is present in the center of the root apex and the cell division is very few in the quiescent center. Itconsists of cells which are much thickened at thecorners due to a deposition of cellulose,hemicellulose and pectin.
Anatomy of Flowering Plants Plant Tissues A collection of cells performing a specific function is called tissue. The vascular tissue system: Epidermis — It is the outer most layer of the primary plant body. Flowers have been symbols of beauty in most civilizations of the world, and flower giving is still among the most popular of social amenities.
A flower having sepals, petals, stamens, and pistils is complete ; lacking one or more of such structures, it is said to be incomplete. They store food materials in the form of starch or fat, and other substances like tannins.

Plants are the primary food producers of the food chain. What are different types of flowers? They can be classified in many different ways: Based on presence or absence of seeds, Based on whether the plants produce flowers or not, Based on the presence of stems, leaves, and roots.

Anatomy: Anatomy is the study of internal structure of organisms. Plant anatomy includes organisation and structure of tissues. Tissue: A group of similar cells alongwith intercellular substance which perform a specific function.
Anatomy of Flowering Plants Plant Tissues. A collection of cells performing a specific function is called tissue. Plant tissues can be grouped into plant tissue systems each performing specialized functions.
A plant tissue system is defined as a functional unit, connecting all organs of a plant.
Plant tissue system is also grouped into various. Thoroughly revised and updated throughout, the book covers all aspects of comparative plant structure and development, arranged in a series of chapters on the stem, root, leaf, flower, seed and fruit.
