The structural components of the phloem are as follows: It is the essential element which is composed of living cells. Write two differences between striated and smooth muscles. This article is helpful for Class 9 Science Chapter 6 Tissue. Also, the chlorenchyma of phloem parenchyma prepares food by process of photosynthesis. 69 Q1. Required fields are marked *. State its function. In most of the plant, the existence of phloem in both stem and roots is found external to that of the xylem. The Sclerenchymatous tissue, which is a type of permanent tissue makes up the husk of the coconut. It is again subdivided into protophloem and metaphloem. Phloem parenchyma: Provides mechanical strength to … Phloem can define as the specialized tissue of the plant cell which anchors the conductance of food from the photosynthesized part (leaf) to the non-photosynthesized parts (like stem, flowers, buds, fruits, roots). Sieve tube and the companion cells are also known as “, In gymnosperms and pteridophytes, companion cells are, Gymnosperms (Particularly conifers) consist of. 6.1 Are Plants and Animals Made of Same Types of Tissues? Diagrammatically show the difference between the three types of muscle fibres. Give three features of cardiac muscles. Both fibres and sclereids have thin areas on them that are called pits.
