Those plants whose seed contains only one cotyledon or embryonic leaf is known as monocotyledon or simply monocot. In this section, you will learn about characteristics and anatomy of monocot stem. Visit this page to learn about dicot stem.
Those plants whose seed contains two cotyledon or embryonic leaf is known as dicotyledon or simply dicot. In this section, you will learn about characteristics and anatomy of dicot stem. Visit this page to learn about monocot stem.
Bragg’s law was first proposed by Sir William Bragg and his son Sir Lawrence Bragg. They studied about the diffraction of X-rays and devised a method for determining the wavelength of X-rays.

The plants whose seeds have only one cotyledon are called dicots. The structure of dicot root varies greatly from that of the monocots. By understanding the structure of dicot root and monocot root, we can make comparisons between them and distinguish them by studying them under a microscope.

Growth in plants happens in two stages first new cells are produced, secondly these cells expand via uptake of water by the vacuole. The division of cells doesn’t occur throughout the plant – but only in meristematic regions. Expansion, however, can occur anywhere. Thus, in any plant, there are regions containing young cells, maturing cells and matured cells that have lost the capacity to divide.
Michelsons’s Method is a precise method for measuring the speed of light. An octagonal mirror M1 is mounted on the shaft of a variable speed motor. Light from a bright source S is focused at an angle of 45o on one of the faces of mirror M1 after passing through a slit S1. The reflected light falls on a distant concave mirror M2.
According to Newton, when sound waves propagate in air, compression and rarefaction are formed. He assumed that the process is very slow and the heat produced during compression is given to surrounding and heat loss during compression is gained from surrounding. So the temperature remains constant and sound waves propagate through an isothermal process.
Radius of gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concentrated, so that the moment of inertia about the axis may remain the same. Simply, gyration is the distribution of the components of an object. It is denoted by K.
The moment of linear momentum of an object is called angular momentum. Angular momentum is represented by L. The angular momentum of an object about an axis of rotation is measured by the product of the linear momentum of the object and the perpendicular distance between the object and the axis of rotation.
