Morphology of root, stem and leaves pdf

Leaves are arranged along a stem in one of four major ways. When leaves and buds are directly across from each other on a stem, they are said to be opposite. Leaves and buds spaced along a stem in an alternating fashion are termed alternate. Another arrangement is subopposite, in which leaves and buds are not spaced far enough apart to be. structure or morphology , they are all characterised by presence of roots, stems, leaves, flowers and fruits. In chapter s 2 and 3, we talked about classification of plants based on morphological and other characteristics. For any successful attempt at classification and at understanding any higher plant (or for tha Leaf arrangement (attachment of leaves to stem): alternate - one leaf per node; opposite - two leaves per node on opposite sides of stem; whorled - more than two leaves per node.

Root morphology — Roots were sampled from either three (2006) or six (2007) randomly chosen plants. Root samples in 2007 were pooled into two groups of three plants each to obtain suffi cient root material of each order and were sampled twice in June and twice in July. Before root dissection, root segments were rinsed and cleaned with deion respectively. The specific root length (i.e., root length per unit root weight) was 7.4 m∙g−1 at 80 DAP decreasing to 4.4 m∙g−1 at 141 DAP (Table 2). 3.3.

Morphology of Flowering Plants When primary root is short lived and is replaced by a large number of roots, originating from the base of the stem, are called as fibrous roots. Phyllotaxy is the pattern of arrangement of leaves on the stem or branch. This is usually of three types - 1.Alternate 2. Opposite 3 with mainly adventitious roots (roots that arise from the stem) that lacks a taproot is said to have a fibrous root system. Stems - Stems can be modified in many ways, and often serve as underground storage organs.

In free floating hydrophytes, the stem is thick and short, floating on the surface of water (e.g.) Eichhornia. 6. In Nymphaea and Nelumbium the stem is a rhizome. These rhizomes live for many years and produce leaves every year. 7. In rooted plants with floating leaves, the leaves are large, flat and entire (e.g.) Nymphaea, Victoria regia.

Difference between underground stem and root The main differences between underground stem and roots are: udder ground stem bears nodes and internodes whereas nodes and internodes are absent in root The stem and other plant organs are primarily made from three simple cell types: parenchyma, collenchyma, and sclerenchyma cells. Parenchyma cells are the most common plant cells. They are found in the stem, the root, the inside of the leaf, and the pulp of the fruit. Parenchyma cells are responsible for metabolic functions, such as photosynthesis

The plant body represents the sporophyte. The sporophytes are evergreen and tall tree (10 -80 m in height). The body has three parts: root, stem and leaves. The plants bear well developed tap root system. The stem is stout, branched and pyramidal in shape with recemose branches It is differentiated into root, stem and leaves. Stem: Stem is unbranched. It is covered by thick, woody, persistent leaf bases. It makes the stem rough. The apex of the stem is ensheathed by a group of brown scales. The lower of stem is covered by pinnate compound leaves. The growth of the stem is very slow. It produces a cluster of leaves. The eight to 20 leaves that may form are arranged spirally on the stem, and they occur alternately in two opposite rows on the stem. The maize leaf is a typical grass leaf and consists of a sheath, ligules, auricles and a blade. The sheath surrounds the internodes above the node to which it is attached

Secondary Growth - growth in width or diameter which gives rise to secondary (woody or corky) tissues called the secondary plant body stem, leaves, buds, branches, floral buds, flowers, and bolls. •The prominent main stem, or primary axis, results from the elongation and development of the terminal bud or shoot apical meristem. •The main stem consists of a series of nodes, where leaves are attached, and internodes.

Roots do not attach to to the bed of the river or pond where they grow, but just float freely in the water.; The stems and leaf stalks have hollow spaces in them, filled with air à help to float on the top of the water where they can get plenty of light for photosynthesis.; Leaves and stomata are on both surfaces, not just on the underside as in most plant à allow to absorb CO2 from the air. Foliar roots or Epiphyllous roots: When roots arise from leaf they are called as foliar roots. E.g., Bryophyllum, Bignonia. 5.

Morphology Of Flowering Plants - Structure of Flowering Plan

All the flowering plants have roots, stem, leaves, flower and fruits. The underground parts of flowering plant are the root system and the portion above the ground forms the shoot system. The Root. In Dicotyledons, elongation of radicle forms the primary roots which bears lateral roots of several orders called secondary roots, tertiary roots, etc Morphology Morphology (plant parts) (until the roots and above-ground leaves take over). At the top of the bulb is the new growing tip, from which the flower stem will emerge. This flower stem also forms roots (called 'stem roots'), between the top of the bulb and the soil surface. These are crucial in enabling the plant to absor In Opuntia, the leaves are modified into spines and the stems becomes fleshy leaf like phylloclade. In Casuarina the leaves are modified into scales.

Definition of Stems. Stems are the part of the plant, that possesses buds, leaves and roots at its basal ends. The primary function of the stem supports the leaves and to transport minerals and water to the leaves, where it proceeded to convert into useful products by the process of photosynthesis, and then further these are transported to other parts of the plants including roots From the life cycle point of view the most important part of a plants is: a) Flower b) Leaf c) Stem d) Root 45.

Root system consists of primary roots (5) and secondary roots (6). The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchorage to the plant parts, storing reserve food material and synthesis. leaves of the stem not clasping, stems hispid-bristly, and capsules shorter than 23 mm long (vs. P. somniferum, with leaves of the stem cordate-clasping, stems glabrous, and capsules 25-60 mm long).

The 'cot' of the plants is actually an embryonic leaf. The cots work to feed the germinating seedlings. This is because the root system of the young plants remains underdeveloped. There are certain differences between the anatomy of monocot and dicot plants. There are the difference between monocot stem and dicot stem, as well. Monocot Stems The root system is below ground. State two functions of plant roots. Angiosperms are divided into two different groups, monocots and eudicots. These groups differ based on tissue organization in the seed, root, stem, leaf and flowers. For example, monocots have leaf veins that form a parallel patter and flower parts in multiples of threes Words are made up of roots, bases, stems, derivational endings, inflectional endings, and occasionally clitics. Not everyone agrees on these forms or on the names of them. This includes Katamba. If we include base-extenders (stem-extenders_ as some kind of near-morph or submorph, then a root is that. Dicot leaves are not as linear in shape as monocot leaves, and their vascular structures form net-like veins, instead of parallel ones. This reticulate venation pattern generally has one of two appearances. A leaf with a pinnated pattern (like a feather) has a central vein running down the middle of the leaf with other veins branching off to either side of it Statement 2: Adiantum grows vegetatively by their leaf tips. 20. Statement 1: In corymb, all the flowers lie at the same level. Statement 2: Pedieels of all the flowers are of same length. 21. Statement 1: An incomplete flower can be perfect. Statement 2: Perfect flowers (incomplete) are called neuter. 22
