Spermatogenesis: Describe its Process and Function

The production process of sperm and egg (gametes) is called gametes (spermatogenesis and oogenesis). Gametogenesis involves two rounds of meiotic cell division, in which a diploid cell forms 4 haploid cells. This figure shows the process of spermatogenesis. The germinal hair (glossy epithelium) of seminal tubules contains spermatogenic cells and supporting cells. (Click here to […]

Binomial Nomenclature: Define With Examples

Binomial Nomenclature Definition Binomial nomenclature is a binomial system for naming species. The binomial name consists of two parts, namely the common name (genus name) and the specific name (or the specific epithelium in the plant name). It usually takes the Latin form. Synonyms: Binomial nomenclature; Binary nomenclature Binomial naming system. Binomial Nomenclature In Biology […]

Nostoc structure: important and reproduction

Nostoc belongs to the genus Cyanobacteria in Monera. Blue-green algae. Nostoc is common in blue and air bacteria. It is widely distributed in alkaline soils, wet rocks, ponds, streams, and lakes. Several filaments are included in the mass. Individual capillaries are called trachomata. Linear Trichome-like bead structure. The structure of the Nostoc The body of […]

Algae: Its Characteristics and Classification

Algae are primitive plants without blood vessels and no real roots. They produce spores instead of seeds, and most have sexual and asexual reproduction. Fungi are eukaryotic heterotrophic organisms that increase hype to form retaliated mycelia. They are not plants. Algae and fungi have many characteristics and are divided into several distinctions, categories, and orders, […]

Slime mold: Structure and Its Types

Slime mold is a fungus-like organism that has certain properties and is therefore included in the roofs of the kingdom. Slime mold Structure The mucus template consists of a large amount of cytoplasm covered with the plasma membrane and the mucus layer. The cell wall does not exist, the naked cytoplasm contains many nuclei, and […]

What Is Biology? Fields and levels of Biological Organization

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development, and evolution.It’s derived from the Greek words “bios” (life) and “logos” (study). Biologists study the structure, function, growth, origin, evolution, and distribution of living organisms. Fields and levels of Biological Organization These are […]

Biological Science: Different Fields of Biology

Biology covers all departments of natural sciences and studies all aspects of life processes. This concept includes anatomy, physiology, Biological Science, biochemistry and biophysics, and covers all living things from microorganisms and animals to plants. What’s Biological Science? Biological sciences are the study of life. This broad, flexible topic studies all living things, where you […]

Factors Affecting Absorption of Water By Plants

Two types of plant factors (internal factors) and environmental factors (external factors) both affect how plants Absorption of Water through their roots. These factors include soil factors (exogenous factors), such as soil temperature, the solubility (osmotic potential) of the soil solution, soil aeration (concentration 02 and carbon dioxide accumulation), soil water, and there are activities […]

Mechanism of Ion Absorption by Roots

Nutrition, University of California, Berkeley, California INTRODUCTION In view of the recent comprehensive reviews by Robertson (13) and by Hewitt (4) and because of the fact that detailed annual coverage of the subject is readily available in abstract form, it was felt desirable to confine this article largely to the basic feature of mineral nutrition, […]

Difference between Environment and Ecosystem

The main difference between the environment and the ecosystem is that everything that exists in the surrounding environment in which the living organism is called is the difference between the environment and the ecosystem. For example, physical force, natural force, and chemical force are the environment, while independent living systems with biological components and their […]

Difference Between Photosynthesis and Respiration

The main difference between photosynthesis and respiration is that photosynthesis occurs during the day, and breathing occurs during the day and at night. Leaves (and other active metabolic tissues) breathe at night. They use oxygen to release carbon dioxide. Low intensity at dawn and dusk. Therefore, the photosynthesis rate and respiratory rate become equal in […]

Comparative Embryology & Embryonic Development

Embryology is the study of fetal development from fertilization to becoming a distinct embryo or species. Comparative embryology is a comparison of fetal development across species. All embryos travel from one cell to a multicellular zygote before differentiation, which is a group of cells called raspberries and a hollow ball called the blastocyst, thus forming […]
