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 Seed Dispersal? Types of Seed Dispersal Seed dispersal is a critical process for plant reproduction, ensuring that seeds are spread to new locations where they can germinate and grow. Various methods have evolved, each adapted to different environmental conditions and ecological interactions. The primary types of seed dispersal include: Agents of Seed Dispersal … Read more
What is Seed? Size and shape of Seed The size and shape of seeds exhibit considerable diversity, reflecting their adaptation to various ecological niches and functional requirements. This variability plays a crucial role in dispersal, survival, and germination strategies. Type of seed Seeds can be classified based on various criteria, including the number of cotyledons … Read more
What is Pollination? Definition of Pollination Pollination is the transfer of pollen from the male part (anther) of a flower to the female part (stigma) of the same or another flower, enabling fertilization and seed production. Process of Pollination Pollination is a critical phase in the reproductive cycle of flowering plants, involving several key steps: … Read more
Animal cell are considered to be the fundamental living species belonging to the kingdom Animalia. They are eukaryotic cells which means they possess an actual nucleus as well as organelles, which are special structures which perform various functions. Animal cells don’t have specific organelles for plants, such as cell walls that support the plant cell or the chloroplasts, an organelle that is responsible for photosynthesis.
Gram-staining used to differentiate between Gram-Positive and Gram-Negative Bacteria.
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
What is Ovule? Definition of Ovule An ovule is a small structure within the ovary of a plant that contains the female gamete (egg cell) and develops into a seed after fertilization. Location of Ovule The location of ovules in flowering plants is intricately tied to their role in reproduction and is defined by various … Read more
Acetoacetic acid and acetone react with an alkaline solution of sodium nitroprusside to form a purple-colored complex. This method can detect above 1-5 mg/dl of acetoacetic acid and 10-20 mg/dl of acetone. Beta-hydroxybutyrate is not detected.
What is Mycorrhiza? Definition of Mycorrhiza Mycorrhiza refers to the symbiotic association between specific fungi and plant roots, where the fungus aids in nutrient and water uptake for the plant, and in return, the plant provides the fungus with essential nutrients produced through photosynthesis. Types of Mycorrhizae Mycorrhizae represent diverse symbiotic associations between fungi and … Read more
