Microsporogenesis and Megasporogenesis: NEET Notes, Steps & Differences Microsporogenesis and Megasporogenesis: NEET Notes, Steps & Differences Quick Summary: If microsporogenesis and megasporogenesis feel confusing, don't worry — the basic idea is actually quite simple. Both processes involve the formation of haploid spores through meiosis, but they happen in different parts of the flower and lead to different gametophytes. Microsporogenesis happens in the anther and produces microspores that develop into the male gametophyte, while megasporogenesis happens in the ovule and produces the functional megaspore that develops into the female gametophyte, or embryo sac. This guide breaks both processes into simple steps and gives you the comparison points that are especially useful for NEET revision. Microsporogenesis and megasporogenesis are important concepts from the reproduction of flowering plants. They explain how male and female spores are produ...
Plant tissues form the basis of plant growth, support, and physiological activities. A tissue is a group of similar cells performing a specific function. In plants, tissues are broadly classified into Meristematic tissues and Permanent tissues. --- 1. Meristematic Tissues These are actively dividing tissues responsible for plant growth. Apical meristem: Present at root and shoot tips; helps in elongation. Intercalary meristem: Found at the base of nodes and leaves; helps in regrowth. Lateral meristem: Found in cambium; responsible for secondary growth. Characteristics Cells are small, thin-walled, and actively divide. Nucleus is large, vacuoles are absent or very small. --- 2. Permanent Tissues These tissues are formed from meristematic tissues once they lose their ability to divide. They are of two types: (a) Simple Permanent Tissues Made of similar cells. Parenchyma: Living cells with thin walls; store food and water. Collenchyma: Elongated cells with unevenly thick walls...
