Indole compounds (e.g, IAA, IBA) help to prevent fruit and leaf drop at early stage but promote the abscission of older mature leaves and fruits. Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen containing pyrrole ring.

Question 1

The cells of bacteria, fungi, algae and plants have an additional non-living, rigid structure called the cell 1. Fungal cell (NAG) units. 2. Algal cell wall : The algal cell wall is made up of cellulose, galactans, mannans and minerals like calcium carbonate. 3. Plant cell wall : The plant cell wall is chiefly composed of the insoluble polysaccharides (cellulose). Certain other compounds, such as hemicellulose, pectin and proteins are also present in the cell wall. The cell wall of plants consists of two regions : primary wall and secondary wall. Primary wall : A young plant cell forms a single layer of wall material. This layer is known as the primary cell wall. The primary wall is thin, elastic and capable of expansion in a growing cell. It grows by addition of more wall material within the existing one. Meristematic and parenchymatous cells have primary cell wall only. Secondary wall : In mature cell, more layers of wall material are added internal to the primary wall which gradually diminishes with maturity. These layers are called the secondary cell wall. Addition of secondary wall brings about thickening of the cell wall. Thickening of cell wall occurs particularly in cells that form the harder woody parts of plants such as lignified and suberised cell wall. Middle lamella : Adjacent cells in a plant tissue are held together by a thin, sticky, amorphous layer of cementing material. This layer is called the middle lamella. Middle lamella is chiefly made up of calcium and magnesium pectate. In ripening fruits, the pectate compounds solubilize to a jelly-like material, making the fruits soft. The cell wall and middle lamella may be traversed by plasmodesmata which connect the cytoplasm of neiahbouring plant cells.
