Spongy tissue is a type of tissue found both in plants and animals. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll's function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis. The spongy mesophyll cells are less likely to go through ...
Limnobium laevigatum is a floating aquatic plant, which can be mistaken for water hyacinth (Eichornia crassipes) due to their superficial similarity.Juvenile plants grow in rosettes of floating leaves that lie prostrate upon the water surface, a distinguishing character of the juvenile plant is the presence of spongy aerenchyma tissue upon the abaxial surface (underside) of the leaf.
Aerenchyma in stem cross section of a typical wetland plant. Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.

Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Aerenchyma (white spongy air-conducting tissue that gives stems buoyancy) forms on stems floating in water, but does not form on stems growing on land. Plants typically grow to as much as 6" tall, but stems will spread in the water to 3-5' long. Stems are clad with bi-pinnate, fine, mimosa-like sensitive leaves that close up when touched.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]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 ...
Patel — who recommends sinus rinsing with a squeeze bottle — notes that these cases are rare and that while it’s “obviously scary to hear about,” you don’t need to skip sinus rinsing.
