What is Multicostate venation?
What is Multicostate venation?
When a leaf has more than one midrib, then it is called as multicostate venation. In parallel venation, veins run parallel for the length of the leaf, from the base to the apex. Typically found in most monocotyledons, such as grasses, palms, castor etc.
In which plants Multicostate parallel venation is found?
grasses and palms. banana and Canna. mango and peepal.
What is reticulate and parallel venation?
reticulate venation= when the veins the leaf lamina divide repeated forming a network it is called reticulate venation. parallel venation= when the veins Run parallel to each other from the base to the tip of the laminar it is called parallel venation .
What are the examples of reticulate venation?
Reticulate venation – Reticulate venation includes irregular vein arrangement for the creation of a network. Examples: Hibiscus, papaya, leaves of Tulsi, Coriander, China Rose, Mangifera, Parallel venation – Parallel venation means that the veins run parallel to each other.
What is Unicostate and Multicostate?
UNICOSTATE:When only one midvein is present, while all other veins form the network like structure is known as Pinnate reticulate venation. This venation is also called as Unicostate reticulate venation. MULTICOSTATE: a leaf, shell, or coral)having several costae or ribs.
What is Multicostate?
multicostate in British English (ˌmʌltɪˈkɒsteɪt) adjective. (of a leaf, shell, or coral) having several costae or ribs. Collins English Dictionary.
Which of the following is an example of Unicostate parallel venation in leaves?
Banana and Canna are examples of unicostate parallel venation.
What is parallel venation in leaves?
Venation is the arrangement of veins in a leaf. Parallel venation is where the secondary veins run parallel to each other and are connected laterally by minute and straight veinlets. This type of venation is mostly seen in monocots.
What is parallel venation of leaf?
What is reticulated venation?
Reticulate venation refers to the arrangement of veins in a leaf where they form a web-like structure. Smaller and more delicate veins emerge from the midrib and spread in the entire leaf. For example, mango and rose leaves; their veins form a network. 3.
What are the example of parallel venation leaves?
Parallel venation: In some leaves, the veins run parallel to each other. Such leaves have are said to have parallel venation. Example: banana, grass and wheat.
What is Unicostate venation?
Pinnate venation is also called as unicostate venation. In this, the lamina has a single principal vein or midrib. It produces lateral veins. Palmate venation is also called as multicostate venation. In this, lamina has more than one principal vein.
What is the difference between multicostate and unicostate leaf lamina?
Unicostate: The leaf lamina possesses a single main vein which gives rise to a large number of lateral veins. All the lateral veins run parallel towards margin. Example: Banana, Canna etc. Multicostate: The leaf lamina possesses several main veins which run parallel to each other.
What is another name for multicostate venation?
Another name for multicostate venation is Reticulate venation. Reticulate venation is of two types – pinnately reticulate venation and palmately reticulate venation. In palmately reticulate venation, more main veins rise from the base of the leaf. Hence, it is also called multicostate venation.
What is a venation leaf?
This venation leaf contains a prominent midrib from which several secondary veins arise that branch and anastomose like a network. It is common in all dicot leaves. It is of two types. Pinnate reticulate venation (unicostate) and Palmate reticulate venation (multicostate)
Which type of venation is common in all dicot leaves?
This type of venation is common in all dicot leaves. It is of two types. 1. Pinnately reticulate venation (unicostate): In this type of venation there is only one midrib in the centre which forms many lateral branches to form a network. Example: Mangifera indica, Ficus religiosa, Nerium.
