Scale-Leaves: In times of extreme heat in the gardens and rose beds, the roses can have problems getting enough moisture to the far outer edges of rose leaves, as well as the outer edges of the petals on blooms, thus they get burned by the heat. When all the mid-ribs diverge out from the leaf base and do not converge towards the apex, e.g., papaya, castor, cucumber etc. In many plants the leaf base expands into a sheath which partially or wholly clasps the stem. E.g., oleander (Nerium) devil’s tree (Alstonia). (Fig. TOS4. E.g., Ixora, madar (Calotropis). 4.7). Mango, Cucurbita, Guava etc., are the examples of simple entire leaves (Fig. Stipules occur on the ventral side of the petiole and the margins of the stipules meet one another to serve as bud scales.

(Fig. The leaves are pointed and the leaf margins are notched. Why does plant cell possess large sized vacuole? On the basis of number to leaflet, a palmately compound leaf may be of the following types: In this type only one leaflet is attached on the apex of lamina, e.g., Citrus (lemon). It is the characteristic of most dicot leaves except Calophyllum. In Gloriosa superba the leaf apex is modified into a tendril. (Fig. When these stipules are present, the leaf is said to be stipulate and when absent exstipulate. This gives off lateral veins which reach the margin or apex of the leaf. Question 5. Venation in Leaves 2. In this type, two leaflets are present on the apex of the petiole, e.g., Balanitis, Hardwickia, Bignonia grandiflora, Princepia etc. Two lateral stipules grow adhering to the petiole upto a certain height, thus making it somewhat winged. It is of two types – Reticulate and Parallel. The leaf is lateral, generally flattened structure borne on the stem. When the direction of incision is towards the petiole, e.g., Ricinus (Castor), Carica papaya (Papaya). True stem of banana is an underground stem. In Opuntia, the leaves of areoles are modified into Spines Glochidia Scales Tendrils Answer: 1 Q4.

Lak phul; H. Agast), etc., or odd in number (imparipinneate), as in rose, margosa (Neem) etc. The arrangement of veins and the veinlets in the lamina is known as venation. 6. E.g., Rose. At the junction of the leaf blade and culm sheath is a small scalelike ligule. Leaves may be simple, with a single leaf blade, or compound, with several leaflets.In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules; compound leaves may have a rachis supporting the leaflets.

The arrangement of the leaves in various modes at the nodal region of the stem is called phyllotaxy. Leaf Blade can also be used as part of a Contest Spectacular combination, with the user gaining extra three appeal points if the move Focus Energy was used in the prior turn. If the rachis is branched once and the leaflets arise on the secondary rachii the leaf is said to be bipinnate. When the tertiary rachii are further branched i.e., more than thrice pinnate. 0. ROMANTIC RED ROSE. Pinnately compound leaves are of the following types: When the rachis of a pinnately compound leaf bears the leaflets, it is said to be unipinnate. Generation IV onward. A leaf is said to be compound when the incision of the leaf-blade goes down to the midrib (rachis) or to the petiole so that the leaf is broken up into a number of segments, called leaflets. Purchase canvas prints, framed prints, tapestries, posters, greeting cards, and more. E.g., wood apple (Aegle). A leaf is said to be simple when it consists of a single blade which may be entire or incised (and, therefore, lobed) to any depth, but not cut down to the mid-rib or the petiole. On the basis of number of mid-rib, the parallel venation is of following two types: (A) Pinnate or Unicostate Parallel Venation: In this type, lamina has a mid-rib in the centre. 4.4). Who we are. In some plants petiole and leaf base, both become broad, Hat and winged. E.g., Hibiscus. What is the reserve food material in red algae? When all the mid-ribs diverge out from the leaf base but again converge towards the apex of the lamina e.g. E.g., Palmyra palm. In this type of venation there is a prominent midrib in the median region. In many plants, it is not demarcated from the petiole. Some common types of leaf bases found in angiosperms are given below. It is again of two types. 4.2-A), mango, banyan, gold- molhur etc., the leaf base becomes distinctly swollen and forms a broadened cushion-like structure, the pulvinus, (Fig. Leaf MCQ (Multiple Choice Questions and Answers) Q1. On the upper leaf side pale green on the underside snow white tomentose. (Fig. Bladder: In Utricularia which is an aquatic insectivorous plant, segments of the leaf modify into bladder like structures which trap small insects present in the water. E.g., gum tree (Acacia), Cassia. It may similarly be quadrifoliate, pentafoliate or multifoliate, according as the leaflets are four, five or more in number. Some important examples are Zea mays, sugarcane, wheat, banana etc. Phyllotaxy 5. When only a single leaf develops at each node alternatively, it is an alternate type of phyllotaxy.E.g. The upper (ventral) surface of lamina is called adaxial while lower (dorsal) surface is called abaxial. E.g., Opuntia. In Australian acacia (Acacia auricular form is) and Parkinsonia petiole is modified into a leaf-like structure called phyllode. Leaves with stipules are called stipulate and those without are called exstipulate. Answer Now and help others. It was also discussed on this related thread: Re: Syntax for icon in Tree element If you are running 4.0, then my recommendation would be to … It is always possible to distinguish a compound leaf attachment to the stem from a leaflet attachment to the petiole and rachis. LOCAL: (919) 985-3124. E.g., bay leaf (Cinnamomum), Indian plum (Zizyphus). These are free from one another, that is, not connected by any lamina, and more or less distinctly joined (articulated) at their base. A bud (axillary bud) is present in the axil of a simple or a compound leaf, but it is leaf never present in the axil of the leaflet of a compound leaf. (Fig. E.g., Zizyphus. Palmately compound leaves are of the following types: A single leaflet is articulated to the petiole. The interior of the pitcher is slippery. E.g., peepul (Ficus), mango (Mangifera). The veins and vinelets not only support but also conduct water, minerals and food thought the leaf. (a) Leaf apex (b) Leaf Lamina (c) petiole (d) axis.
