Introduction: When and where certain genes are activated, and the amount of protein or RNA product generated is dependent on multiple factors. They are determined by a complex series of interactions between genes, RNA molecules, proteins (including transcription factors), and other components of the expression system. The process of turning a gene on and off…
Introduction Nonvascular plants are non-flowering plants that do not have specialized tissues like vascular tissues to transport water and minerals to the rest of the plant body. They are low-growing forms of plants that are found growing in moist habitats. Examples of nonvascular plants include mosses or Bryophytes, liverworts or Hepaticophyta, and hornworts or Anthocerophyta….
Introduction: Angiosperms are flowering plants — one of the vital groups of plants with seeds inside themselves. Angiosperms represent approximately 80% of all the known green plants now living. Explain the reproduction process of angiosperms. Reproduction in flowering plants starts with pollination, the transference of pollen from anther to stigma on the same flower or…
Introduction Like all living things, plants grow, reproduce, and go through a life cycle. The life cycle of a plant explains the many stages of the plant’s existence, beginning with seed and ending with a mature plant. Let’s go through them together below! The Life Cycle of a Plant The Plant Cycle can be broadly…
Introduction Plant tissues are groups of cells that are similar in their origin and their structure and perform similar functions. They are a collection of similar cells that perform organized functions for their plants. They are specialized for a unique purpose, and they can be combined with other tissues creating organs like flowers, stems, leaves,…
Introduction Vascular plants are also called tracheophytes. Tracheophyta is derived from the Greek word trachea, which means a duct–a channel in plants. The vascular plants are well-ordered, as are the land plants, including blooming vascular plants and ferns. They have developed a sophisticated network of vascular systems that run throughout the plant body, allowing for…
Introduction Spermatophytes are seed-producing plants. It was a huge event when vascular plants evolved to produce seeds, and it was possibly just as significant as the emergence of vascular tissues in plants! Gymnosperms (seeds in cones) and angiosperms (seeds in capsules) are the two main categories of seed plants (seeds in ovaries of flowers). The…
Introduction: Every cell in our body contains DNA or deoxyribonucleic acid. It is the carrier of genetic instructions that makes every species unique and drives the development and functioning of an organism. DNA Structure The structure of DNA is a double helix, and it looks like a twisted ladder. A pair of nitrogenous bases make…
Introduction Plants live in nearly every part of the earth. To live and survive in different environments, they have developed adaptive capabilities that allow them to survive and reproduce under difficult conditions. Unlike animals, plants can’t run, fly, or swim towards food or against danger, making these adaptations critical for survival. Let’s talk about some…
Introduction In 1678, Anton van Leeuwenhoek, a Dutch microscopist who co-discovered sperm, believed semen consists of parasitic material. He thought that sperm had nothing to do with reproduction of new life. But, with time and experiments, he understood that each sperm consists of an embryo. Gametogenesis is derived from two Greek words, “gamete” and “genein.”…
