The leaves in most legume species are compound (Lewis et al. 2005). Pea, with its pinnately compound leaf consisting of basal, foliaceous stipules, proximal leaflets and distal tendrils, serves as a model species for understanding compound leaf development (Yaxley et al.
What shape of leaf does a pea plant have?
The leaflets are ovate, entire, 1.5 – 6 cm long and 1-4cm broad. There are 1–4 pairs of pinnately-veined leaflets per side with the terminal leaflet pair modified into a branched tendril. Leaflets are essentially sessile. The stipules are large, up to 10cm long (usually 1.5-8 cm), on round, slender, and glabrous stems.
Do peas have leaves?
Pea leaves turn yellow for several reasons. Often, this is due to the stress of hot weather.
Do peas have Dorsiventral leaves?
pea leaves are dorsiventral and amphistomatous in structure (Figure 2). Transverse sections of control plants displayed upper (adaxial) and lower (abaxial) epidermal layers with compactly arranged, large, barrel-shaped cells and mesophyll with dorsiventral organisation (Figure 2, control).
Is pea a root stem or leaf?
A pea plant has two main parts: root and shoot. The root grows within the soil while the shoot is the above ground portion of the plant.
What is the Venation of pea plant?
reticulate venation
Pea plant shows reticulate venation.
What is the correct description of peas?
Description. A pea is a most commonly green, occasionally golden yellow, or infrequently purple pod-shaped vegetable, widely grown as a cool-season vegetable crop. The seeds may be planted as soon as the soil temperature reaches 10 °C (50 °F), with the plants growing best at temperatures of 13 to 18 °C (55 to 64 °F).
Are peas vines?
Every part of the Pisum sativum plant is edible, and that includes the thin pea vines and pea leaves. Since the pea plant is a climbing vine, the majority of the plant itself is comprised of its vines and leaves.
Why are peas called peas?
In AngloSaxon the word became pise or pisu; later, in English it was “pease.” So many people thought pease was plural that they persisted in dropping the “s” sound, thus making the word “pea.” The Latin name resembles the older Greek pisos, or pison.
Can we eat peas leaves?
RAW: Both the leaves and the stems of pea greens are edible. We recommend pairing the uncooked greens with a light vinaigrette so their delicate grassy flavor comes through. COOKED: Lightly sauté the greens to highlight their savory flavor. They will wilt to about one-third of their uncooked volume.
What is the type of the leaf?
There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc.
What is leaf venation and types?
Venation is the phenomenon of arrangement of veins in the lamina of the leaf surface. It is of three types, reticulate, parallel and furcate venation. In reticulate venation, veins form the network like structure. For example, leaves of dicot plants. In parallel venation, veins arise from the mid rib and run parallel.
What are Isobilateral leaves?
In an isobilateral leaf, the stomata are present on both the surfaces of the epidermis; and the mesophyll is not differentiated into palisade and spongy parenchyma (Figure). These types of leaves are similar in appearance on both sides and hence, are called an isobilateral type of leaves.
Is pea example of leaf tendril?
Leaf tendrils (peas) are actually modified leaves that emerge from a leaf node.In pea plants it is only the terminal leaflets that are modified to become tendrils.
What kind of roots do peas have?
The shoot and root having developed from inside the pea. The root architecture developing from one primary root which grows downwards more or less straight. From this primary root a large number of secondary (or lateral) roots have branched to fill the pot as it has grown.
Is pea plant a climber?
– The stem of a pea plant is very weak. As it can not stand by its own, it climbs with the help of another plant or wall and sticks with them. With the help of the tendril, it climbs the support. So, the pea plant is a climber.
Which of the following plant shows parallel venation?
Complete answer:
Parallel venation is found in the Banana plant. Other plants showing parallel venation include grains, banana, canna, grass, musa, maize, etc.
Which type of venation is found in grass?
Grass leaves exhibit a parallel leaf venation pattern, in contrast with the typical reticulate venation of dicot leaves, and there is a central vein, or midrib, that provides structural support to the leaf.
Does Rice have reticulate venation?
Answer: Rice has parallel venation because it is a monocot plant.
Why are peas green?
It is now known that the green colour of mature pea seeds is due to the abundance of chlorophyll (a central component of the plant photosynthetic machinery).
Is pea a seed or a fruit?
Peas (also kidney beans, chick peas and fava beans) might fool you. They are fleshy and don’t look like stems or leaves, but they are not fruit. The pea (or bean) is the seed. They all grow in the same kind of pod that is the fruit, and are very high in protein.
