What are Plant Tissues? Plant tissues are organized cell groups within a plant that collectively enable essential life functions, like growth, protection, and nutrient transport. There are two main categories of plant tissues: meristematic and permanent. Meristematic tissues contain actively dividing cells that promote growth. Found in regions like root and shoot tips, these cells … Read more

Wha is Stomata? Definition of Stomata Stomata are tiny pores located on the epidermis of plant leaves and stems that regulate gas exchange, allowing carbon dioxide, oxygen, and water vapor to enter and exit the plant. Each stoma is flanked by guard cells that control its opening and closing, facilitating processes such as photosynthesis and … Read more

What is Embryo Development in Plants? Development of the embryo (Embryogenesis) The development of the embryo in angiosperms, known as embryogenesis, is a complex and highly regulated process that transforms a diploid oospore (zygote) into a mature embryo. This process involves several key stages and can be categorized into different types based on the patterns … Read more

What is Polyembryony? Definition of Polyembryony Polyembryony is the development of multiple embryos from a single ovule or seed, resulting in several embryos within the same seed, which are genetically identical to each other but distinct from the parent plant. Types of Polyembryony Polyembryony can be classified based on various criteria including the source of … Read more

What is Endosperm? Definition of Endosperm The endosperm is a tissue found in seeds of flowering plants that provides nourishment to the developing embryo. It is formed from the fertilization of a secondary nucleus by a sperm cell and can vary in structure, including nuclear, cellular, or ruminate types, depending on the plant species. Characteristic … Read more

What is an Embryo Sac? Definition of Embryo Sac The embryo sac is the female gametophyte in flowering plants, located within the ovule, where fertilization occurs, leading to the development of the seed and endosperm. Structure of Embryo Sac The structure of the embryo sac, also known as the mature female gametophyte, is integral to … Read more
