Upgraded B002 Ntbi0502 Layered Dicot Leaf Mesophyll — a labelled NEET Biology diagram with a definitions lexicon.
Diagram illustrating the layered structure of dicot leaf mesophyll. Labelled parts: Palisade Mesophyll, Spongy Mesophyll, Photosynthesis, Cross-section, Ground Tissue, Gas Exchange, Chloroplast, Epidermis, Mesophyll, labeling of, Condenser, airy. A layer of vertically elongated cells rich in chloroplasts found just beneath the upper epidermis of leaves. The lower layer of leaf mesophyll consisting of loosely arranged, irregularly shaped cells with large air spaces. FYI: These air spaces facilitate rapid gaseous exchange between the atmosphere and the photosynthetic cells. The physico-chemical process by which green plants use light energy to drive the synthesis of organic compounds from CO2 and water. FYI: It is the primary source of all food on Earth and is responsible for the release of oxygen into the atmosphere. A diagrammatic view of an organ or tissue obtained by cutting it at a right angle to its longitudinal axis. FYI: Transverse sections (T.S.) are standard in plant anatomy to study the arrangement of vascular bundles. The tissue of a plant other than the epidermis, periderm, and vascular tissues, prominent in monocot stems. The process by which respiratory gases (O a ‚‚ and CO a ‚‚) move between the external environment and the blood. In humans, this occurs primarily across the alveolar membranes. FYI: Gas exchange relies on the partial pressure gradient; gases move from an area of higher partial pressure to an area of lower partial pressure. A double-membraned plastid containing chlorophyll pigments that performs photosynthesis to convert light energy into chemical energy. FYI: Chloroplasts are found mainly in the mesophyll cells of leaves and are thought to have evolved via endosymbiosis. The outermost protective layer of cells in plants, often covered by a waxy cuticle to prevent water loss. FYI: In roots, the epidermis contains specialized extensions called root hairs for water absorption. The ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis. labeling of is a labeled feature or concept in this upgraded BioAtlas image: Cross-section diagram of a dicot leaf showing clear demarcation and labeling of: Upper Epidermis, Palisade Mesophyll (dense), Spongy Mesophyll (airy), Lower Epidermis. Use color... A cooling device in the Miller-Urey experiment used to liquefy the gaseous products and water vapor. FYI: This simulated the cooling of the Earth's atmosphere and the subsequent rainfall. airy is a labeled feature or concept in this upgraded BioAtlas image: Cross-section diagram of a dicot leaf showing clear demarcation and labeling of: Upper Epidermis, Palisade Mesophyll (dense), Spongy Mesophyll (airy), Lower Epidermis.
