  2. Organogenesis - Wikipedia

    en.wikipedia.org/wiki/Organogenesis

    In plants, organogenesis occurs continuously and only stops when the plant dies. In the shoot, the shoot apical meristems regularly produce new lateral organs (leaves or flowers) and lateral branches. In the root, new lateral roots form from weakly differentiated internal tissue (e.g. the xylem-pole pericycle in the model plant Arabidopsis ...

  3. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]A germination rate experiment. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...

  4. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...

  5. Plant cognition - Wikipedia

    en.wikipedia.org/wiki/Plant_cognition

    Plant cognition. Plant cognition or plant gnosophysiology[1] is the study of the learning and memory of plants, exploring the idea it is not only animals that are capable of detecting, responding to and learning from internal and external stimuli in order to choose and make decisions that are most appropriate to ensure survival.

  6. Respiration (physiology) - Wikipedia

    en.wikipedia.org/wiki/Respiration_(physiology)

    Ventilation refers to the in-and-out movement of air of the lungs and perfusion is the circulation of blood in the pulmonary capillaries. [1] In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement that brings air into the lungs where the process ...

  7. Organ (biology) - Wikipedia

    en.wikipedia.org/wiki/Organ_(biology)

    Organ (biology) In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which ...

  8. Ecophysiology - Wikipedia

    en.wikipedia.org/wiki/Ecophysiology

    Ecophysiology (from Greek οἶκος, oikos, "house (hold)"; φύσις, physis, "nature, origin"; and -λογία, -logia), environmental physiology or physiological ecology is a biological discipline that studies the response of an organism 's physiology to environmental conditions. It is closely related to comparative physiology and ...

  9. Plant perception (physiology) - Wikipedia

    en.wikipedia.org/wiki/Plant_perception_(physiology)

    Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
