Definition of Aerobic Respiration Aerobic respiration is a series of metabolic events that occur in the presence of oxygen in order to transform chemical energy into ATPs in a cell. Except for certain early prokaryotes, all plants, animals, birds, and humans use aerobic respiration. In aerobic respiration, oxygen serves as an electron acceptor, allowing ATPs … Read more
Habitat Definition A habitat is a natural setting in which a certain organism lives and relies on its surroundings for survival, food, shelter, protection, and mating. The word habitat comes from the Latin word ‘habitare,’ which meaning ‘to occupy.’ The physical and biological aspects of an organism’s habitat define it. The nature of the soil, … Read more
Monocot Leaves Definition Monocotyledonous plants have narrow, elongated leaves with parallel venation, which is used to distinguish them from dicots. Monocot leaves are isobilateral because the colour on both surfaces of the leaves is same. A proximal leaf base, or hypophyll, and a distal leaf hyperphyll make up the primordial monocot leaves. In dicots, the … Read more
Definition of Archaea Archaea is a group of early prokaryotes that form a unique domain from bacteria and eukaryotes based on their specific properties. The term “Archaea” comes from the Greek word “archaios,” which means “primitive” or “old,” implying the organisms’ primordial structure. Deep-sea vents, saline seas, hot springs, and even beneath petroleum deposits are … Read more
Vascular Plants Definition Vascular plants, also called tracheophytes, are terrestrial plants with lignified tissues that transmit water and minerals throughout the plant’s body. Water-conducting xylem tissue and food-conducting phloem tissue make up these lignified tissues, which are also known as vascular tissue. For the transportation of diverse chemicals, vascular tissue creates a central column, also … Read more
