It is the chief component of ligaments and tendons. Ø The secondary cell wall is lignified and very hard. In some plants living in very dry habitats, the epidermis may be thicker since protection against water loss is critical. Epithelial cells lie on a delicate non-cellular basement membrane which contains a special form of matrix protein, called collagen. Question 1. They are involved in food storage. As a result of improved organization and higher efficiency, multicellular organisms have higher survival. Parenchyma is found in all parts of plant such as cortex, pith, palisade, mesophyll, flower, seed etc; It is also found in vascular tissues.

Ø Parenchyma usually occupies in the ground tissue of stem, root, leaves, petiole and fruits. The parenchyma is present in all the organs of the plants, i.e., roots, stems, leaves, flowers, fruit and seeds. On the basis of their location, structure and function, there are following three types of muscle fibers: Striated muscles (stripped, skeletal or voluntary muscles), Smooth muscles (unstriated, visceral or involuntary muscles). It includes cartilage and bone. The parenchyma is present in all the organs of the plants, i.e., roots, stems, leaves, flowers, fruit and seeds. Pith etc. Parenchyma . Nervous tissue contains highly specialized unit cells called nerve cells or neurons. Cells appear square-like in vertical section but their free surface seems to be hexagonal. Question 2 Write down the functions of parenchyma? 1)They provide mechanical support and elasticity to dicotyledonous stem. Aerenchyma: A spongy or soft plant tissue with large air spaces found between the cells of the stems and leaves of many aquatic plants, which allows exchange of gases between the shoot and the root Chlorenchyma: In some cases the parenchyma cells contain chloroplasts and are called as chlorenchyma.These cells are meant for photosynthesis. Such a parenchyma type is called. Xylem and phloem are both conducting tissues and also known as vascular tissues; together both them constitute vascular bundles. Workload of individual cell ahs decreased due to origin of tissues. The cells are isodiametric, i.e., equally expanded on all sides.

Epidermis of a leaf contain small pores called. It is a fibrous connective tissue. Tissues. Formation of tissues has brought about division of labour in multicellular organisms. Epithelial cells protect the underlying cells from mechanical and chemical injuries and bacterial or viral infection. It is also used for making sports goods, such as shuttle-cock, table tennis paddles, crcket balls, etc. You can identify the sclerenchyma by (a) location of nucleus. 2. Parenchyma forms the bulk of plant body. This tissue is “functional” – performing tasks such as photosynthesis in plants or storing information in the human brain – as opposed to “structural” tissues like wood in plants or bone in animals.. False Question 9 What are the functions of cork cells? Parenchyma forms the framework of all the plant organs and tissues like cortex. They appear at the periphery of roots and stems when they grow older and increase in girth. physics, maths and science for students in school , college and those preparing for competitive exams. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. Parenchyma forms the framework of all the plant organs and tissues like cortex. Basal part of cell bears oval nucleus. Connective tissue also provides the structural framework and mechanical support to different tissues. 1. CBSE NCERT Solutions for Class 9 Science Chapter 6 .

Bones are present in the whole body forming internal skeletal framework. Similarly place and study the other permanent slides of sclerenchyma. The cells of tissue are compactly arranged and do not have intercellular space. The main function of xylem is to carry water and mineral salts upward from the root to different parts of shoots, hence also called water conducting tissue. In that case, parenchyma carries out photosynthesis and is then termed as chlorenchyma. Cells of sclerenchyma are of two types: fibers and sclereids.
