Definition of mesophyll in English: mesophyllnoun ˈmɛsə(ʊ)fɪlˈmɛzə(ʊ)fɪlˈmiːsə(ʊ)fɪlˈmiːzə(ʊ)fɪl mass nounBotany The inner tissue (parenchyma) of a leaf, containing many chloroplasts. Example sentencesExamples - The mesophyll with large vascular bundles resembles an I-beam construction connecting the adaxial and abaxial surfaces.
- A single cell culture, based on protoplasts that were isolated from the leaf mesophyll of tobacco, was used.
- All three transgenic lines presented a significant decrease in the mean size of both epidermal internode and leaf mesophyll cells.
- Stromules tend to be relatively rare in cell types such as mesophyll or guard cells that contain large chloroplasts.
- In mesophyll cells, chloroplasts are dismantled in an early phase of senescence, while mitochondria remain functional.
- Thus, elements of the guard cell's response to stress are present in mesophyll and xylem parenchyma cells.
- Plastids of mesophyll cells from leaves of control or herbicide-treated plants grown at 20°C.
- Inactivation of plastids in the leaf mesophyll, which normally contains the majority of chloroplasts would be the most easily identified.
- They are stored in vacuoles of a specialized leaf tissue, the paraveinal mesophyll.
- As solar angle changes, individual mesophyll cells of the leaf may pass from full sunlight to shade within a second.
- By such thickening, mesophyll surface area per leaf area becomes greater in sun leaves than in shade leaves.
- They also accumulate throughout the leaf in mesophyll tissue and in trichomes.
- It was concluded that stomatal conductance is not directly determined by the photosynthetic capacity of guard cells or the leaf mesophyll.
- It should be interesting to find out where in the leaf this barrier is built up: gradually along the mesophyll or abruptly between xylem and mesophyll.
- In addition, the magnitude of growth-associated is similar between xylem and mesophyll and between xylem and epidermis.
- Messenger RNA was isolated from guard cells and mesophyll tissue as described previously and used as a template for RT-PCR.
- Cytoplasm of the leaf mesophyll of a D. antarctica plant growing in a wet, fertile habitat on the seashore.
- Leaf mesophyll is differentiated into palisade and spongy parenchyma, epidermis is already formed.
- Light dependence of zeaxanthin formation in hypocotyl and mesophyll chloroplasts of Arabidopsis seedlings
- Leaves are composed of various kinds of tissues, including epidermis, mesophyll, bundle sheath, and vascular bundles.
