What are the parts of a monocot leaf?
Monocot leaves have their leaf veins arranged parallel to each other and the long axis of the leaf (parallel vennation). An common example of this is the husk of corn or a blade of grass (both are monocots). Dicot leaves have an anastamosing network of veins arising from a mid-vein termed net vennation.
What is a monocots leaf pattern?
Monocot leaf First, they tend to be more oblong or linear in shape, and their vascular bundles are organized into veins that originate at the base of the leaf and run parallel to one another. In other words, they have a striate venation pattern. There is usually only one leaf per node growing off of the stem.
Which anatomical character is correct for monocot leaf?
Monocot leaves are characterised by parallel venation , leaves are isobilateral (both the surfaces equally green) , amphistomatic with dumb bell – shaped guard cells . The upper epidermis possesses groups of larger sized thin walled vaculate cells called bulliform or motor cells.
How do you identify a monocot leaf?
- Monocotyledonous leaves are narrow and elongated with parallel venation, which is often used to distinguish monocotyledonous plants from dicots.
- Dicotyledonous leaves are usually rounded with reticulate venation that can be distinguished from monocotyledonous leaves in their structure and anatomy.
What does a monocot leaf look like?
monocots have narrow grass-like leaves. Arrowhead (left) is a monocot. Because the leaves have lobes that hang downwards, it almost looks like the veins branch out in the same manner as described for palmate veins. Monocots have flower parts in threes or multiples of threes as shown in the flowers to the left.
What is monocot and dicot stem?
Monocot stem is a circular-shaped hollow axial part of the plant which gives rise to nodes, internodes, leaves, branches, flowers with roots at the basal end. Dicot stem is the solid cylindrical axial part of a plant consisting of nodes and internodes giving rise to leaves, branches, and flowers.
Which of the following is correct about monocot leaf?
In monocot leaf, mesophyll cells are not differentiated into palisade and spongy tissues. But there is well differentiate mesophyll cells in dicot stem. Also in the upper epidermis, there are some large cells found in groups which are called bulliform cells. The venation pattern in monocot is parallel.
Do monocots have Palisade mesophyll?
Most Dicots have a Palisade arrangement of Mesophyll tissues. While monocots either have a uniform Mesophyll or one in which the Photosynthetic Parenchyma are distributed like spokes on a wheel around the Vascular Bundles. This is called Kranz (wreath) Anatomy and signifies that these plants have C4 Photosynthesis.
