Archimedes’ Principle

When a stone is immersed in a bucket completely filled with water, some amount of water spill out of the bucket. The weight of water displaced (spilled) from the bucket can be explained by Archimedes principle.

Monocot Stem

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.

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

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.

Monocot Roots

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 root. Visit this page to learn about dicot root.

Dicot Root

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.

Meristematic Tissues

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.

Velocity of Light Michelsons’s Method

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.
