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 ...
In botany, a sinus is a space or indentation between two lobes or teeth, usually on a leaf. [1] The term is also used in mycology . For example, one of the defining characteristics of North American species in the Morchella elata clade of morels is the presence of a sinus where the cap attaches to the stipe .
The spongy tissue fills with blood, from arteries down the length of the penis. A little blood enters the corpus spongiosum; the remainder engorges the corpora cavernosa, which expand to hold 90% of the blood involved in an erection, increasing both in length and in diameter.
Parenchyma is the tissue made up of cells and intercellular spaces that fills the interior of the body of a flatworm, which is an acoelomate. This is a spongy tissue also known as a mesenchymal tissue , in which several types of cells are lodged in their extracellular matrices .
Chloroplasts in leaf cells of the moss Mnium stellare. 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.

The epidermis is the main component of the dermal tissue system of leaves (diagrammed below), and also stems, roots, flowers, fruits, and seeds; it is usually transparent (epidermal cells have fewer chloroplasts or lack them completely, except for the guard cells.) The cells of the epidermis are structurally and functionally variable.
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.
