In what time will Rs. 1000 amount to Rs. 1300 at 10% simple interest per annum?​

Answer:

H2O

is molecular formula of water

Answer:

The chemical formula for water is H2O, which means this molecule has 3 atoms: 2 of hydrogen (H) and 1 oxygen (O) atom.

Answer:

Internal structure of dicot root:

Epidermis:

It is single-layered and made of cells that are thin-walled. There is no cutinisation of the outer walls of epidermal cells. Many epidermal cells, the traditional unicellular hairs of the roots, extend to form long hairy bodies. Root epidermis is sometimes referred to as epiblema or piliferous layer

Cortex:

In terms of roots, it is very broad and extensive. Cortex is made from leucoplast, thin-walled living parenchymal cells that turn sugar into starch grains. The last cortical layer is the endodermis. It is a natural occurrence in the roots.

One layer of barrel-shaped cells is composed of endodermis, which are tightly organized without having intercellular spaces. There are thickened radial walls in the endodermal cells, which are called Casparian strips, after the name of the gentleman who first noted them, Caspary.

Central Cylinder or Stele:

Next to the endodermis is a single-layered pericycle formed by thin-walled parenchyma cells. The Pericycle is the seat of origin of the lateral roots.Vascular bundles in the roots are usually radial. Xylem and phloem form distinct patches and non-conducting cells intervene in them. The number of bundles in dicotyledonous roots is reduced.

Conjunctive tissue:

The conjunctive tissue is produced by thin-walled parenchymatous cells lying between xylem and phloem groups.

Pith:

A tiny parenchymal pith is in the middle. In dicotyledonous roots, it may also be absent.

Monocot root Dicot root

Cortex Pericycle BicycleIn monocot roots, the With external dead exoderma, the cortex can be heterogeneous (differentiated). Without any distinction, the cortex is homogeneous.

pericycle only produces the lateral roots. The pericycle produces the lateral roots, the cork cambium and the vascular cambium portion.

Pith Pith is a big, well formed monocot root component. It contains a significant number of starch grains. Pith is very tiny or totally obliterated.

Xylem andPhloem In number, Xylem and Phloem are various. The numbers of Xylem and Phloem are limited.

Passage cells Passage cells are typically absent in monocot root endodermis. In the endodermis of dicot roots, normally passage cells are present.

Metaxylem Elements are oval or circular Elements are angular arranged in linear position

Note: Xylem is exarch, i.e. protoxylem lies to the periphery and Metaxylem to the middle in monocot and dicot origin.

Endodermis consists of barrel-shaped parenchyma without intercellular spaces in both the dicot and monocot roots.

In both monocot and dicot roots, pith consists of intercellular spaces of thin walled, polygonal parenchyma cells.

There are radial vascular bundles of both monocot and dicot roots

Explanation:

Answer:

Dicot root: The arrangement of xylem and phloem is different in dicots than it is in monocots. The xylem is all located in the middle of the dicot root, and bundles of phloem are arranged around it, separated from it by vascular cambium. When cells of the vascular cambium divide, they differentiate into secondary growth xylem and phloem, which increases the girth of dicot roots and stems. Monocots do not have vascular cambium.

Since dicot roots don’t have a central pith area, parenchyma serves as connective tissue in the region where the dicot root’s vascular structures are found.

Monocot root: In monocot roots, xylem and phloem tissue bundles are arranged in a circular fashion around the central pith, which consists of ground tissue (parenchyma). Monocot roots have a larger number of vascular structures than dicot roots.
