BIOLOGY | MEDICAL | HEALTH on Instagram: "Cells are the fundamental building blocks of all living organisms, performing essential functions such as energy production, nutrient processing, and reproduction! Despite their complexity, most cells are incredibly small and can only be seen under a microscope. Animal cells typically range from 10 to 30 micrometers in size, while plant cells are generally larger, reaching up to 100 micrometers due to their rigid structures. Bacterial cells are much smal

World of Biology on Instagram: "Meiosis is a special type of cell division that reduces the chromosome number by half and produces gametes (sperm and eggs in animals). It occurs in two successive stages: Meiosis I and Meiosis II. In Meiosis I, the process begins with Prophase I, where homologous chromosomes pair up through synapsis and exchange genetic material in a process called crossing over, which increases genetic variation. This is followed by Metaphase I, where the paired homologous chrom
