Cross section of a maize leaf, a C 4 plant. Kranz anatomy (rings of cells) shown ... While in C 3 photosynthesis each chloroplast is capable of completing light ...
A cross section of a leaf, showing chloroplasts in its mesophyll cells. Stomal guard cells also have chloroplasts, though much fewer than mesophyll cells.
Palisade cells contain a high concentration of chloroplasts, particularly in the upper portion of the cell, making them the primary site of photosynthesis in the leaves of plants that contain them. Their vacuole also aids in this function: it is large and central, pushing the chloroplasts to the edge of the cell, maximising the absorption of ...
Cross section of a Chlamydomonas reinhardtii algae cell, a 3D representation. Pyrenoids are sub-cellular phase-separated micro-compartments found in chloroplasts of many algae, [1] and in a single group of land plants, the hornworts. [2] [3] Pyrenoids are associated with the operation of a carbon-concentrating mechanism (CCM).
Chloroplasts are generally absent in epidermal cells, the exception being the guard cells of the stomata. The stomatal pores perforate the epidermis and are surrounded on each side by chloroplast-containing guard cells, and two to four subsidiary cells that lack chloroplasts, forming a specialized cell group known as the stomatal complex.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Cross section of a leaf showing various ground tissue types Parenchyma cells have a variety of functions: In leaves , they form two layers of mesophyll cells immediately beneath the epidermis of the leaf, that are responsible for photosynthesis and the exchange of gases. [ 2 ]
F bicollateral open Cross section of celery stalk, showing vascular bundles, which includes both phloem and xylem Detail of vascular bundle: closed, collateral vascular bundles of the stem axis of Zea mays Vascular bundle in the leaf of Metasequoia glyptostroboides The vascular bundle of pine leaf showing xylem and phloem
