The images of the stomata were taken with the microscope focused to the narrowest part lower down in the pore. |
|
Ferns generally lack some of the more typical adaptations of xerophytes, such as a thick hypodermis, sunken stomata, and CAM photosynthesis. |
|
As with the photosynthetic apparatus, stomata can acclimate to long-term variation in CO2 supply. |
|
The capsule lacks stomata and on the outside has a trabeculate appearance due to the outermost cells having thickened lateral walls. |
|
It is believed that the gametophyte generation also had water-conducting tissue, cuticle, and stomata, making this species isomorphic. |
|
The outer layer of the abaxial epidermis contains sunken stomata with strongly fluorescing chloroplasts in the guard cells. |
|
Finally, mosses may, like higher plants, also have a waxy cuticle and stomata to help control evaporation. |
|
The zoospores are disseminated by rain splash to grape tissues where they swim to the vicinity of stomata and encyst. |
|
The leaf pores, also called stomata, open to allow in carbon dioxide, which plants need for photosynthesis. |
|
Density of stomata was determined under the microscope using a eyepiece graticule. |
|
Leaf stomata control plant CO 2 absorption through photosynthesis and water loss through transpiration. |
|
The grids were separated into four quadrants and the stomata were counted in each quadrant. |
|
In the carob tree, Ceratonia siliqua, for example, stomata are found not only in normal location in leaves but also in the seedling root. |
|
Many possess, at the base of the ovary, a disc-like nectary from which nectar is secreted via modified stomata. |
|
However, these systems were less developed than those on leaf stomata, a feature that might be responsible for their inactivity. |
|
The CO2 comes directly from the atmosphere, and is absorbed through pores, known as stomata, in a plant's leaves. |
|
The skin or epidermis that surround the stomata secretes a waxy cuticle that inhibits the evaporation of water from the epidermal area of the leaf. |
|
Normally, stem in the Arabidopsis epidermis will divide asymmetrically into a smaller, daughter cell, which eventually form stomata, and a larger daughter cell. |
|
In addition, OsVPE3 affected leaf and stomata guard cell development in rice. |
|
Smaller guard cell length likely increases resistance of water vapor through the stomata. |
|
|
The main waste product, oxygen, they emit through their stomata in a watery belch. |
|
The stomata stay closed for longer, and less water is lost to the atmosphere. |
|
When ozone enters through the stomata, it can interfere with a variety of biochemical and physiological processes, including photosynthesis. |
|
Periods of high temperatures with closure of stomata and reductions in calcium assimilation. |
|
Inoculum from these cankers is disseminated in rain and wind and infects new leaf growth via stomata. |
|
The new method links ozone effects to the plant uptake through stomata on leaf surfaces. |
|
The bacterium enters plant tissue through stomata and other natural openings, as well as wounds and roots. |
|
Spores germinate and enter the leaf through stomata on the lower leaf surface. |
|
Why didn't these early plants grow lots of leaves with few stomata? |
|
Energy is required to provide the latent heat of evaporation for the phase change from liquid to gas, which takes place in the cavity below the stomata. |
|
However, the presence of both adaxial and abaxial stomata on leaves of T. pusillum var. texanum did differentiate it from other taxa in this species complex. |
|
The bacterium can infect through wounds, hydathodes and stomata. |
|
Second, they cause stomata to partly close, thereby reducing the water loss due to transpiration. |
|
The leaves are generally amphistomatic, with more stomata present on the abaxial surface. |
|
Applied a few days into a drought, Bradshaw says Invinsa triggers the plants physiology to close the stomata, the pores on the leaf underside, until the moisture returns. |
|
If the plant gets short of water, it will close the stomata and so prevent too much water loss. |
|
The gas is absorbed through pores called stomata, which also allow water vapour to escape producing a cooling effect. |
|
The structures of the nephron, cochlea and semicircular canals, and leaf stomata can all be modeled with long clown balloons. |
|
The bacterium enters the leaves via stomata or wounds, and subsequently invades the intercellular spaces, causing a gradual dissolution of the middle lamella. |
|
When the aerial stomata are close from morning to the evening, the absorption of materials are doing through the hydathode and cuticle. |
|
|
The stomata are in lines or patches on the leaves, and can be closed when it is very dry or cold. |
|
Water is constantly transpired from the plant through its stomata to the atmosphere and replaced by soil water taken up by the roots. |
|
The movement of water out of the leaf stomata creates a transpiration pull or tension in the water column in the xylem vessels or tracheids. |
|
When amphistomatic, the stomata were more abundant on the abaxial surface. |
|
When conditions are favourable, asexual sporulation takes place by means of sporangiophores arising primarily through stomata or other openings on the invaded tissue. |
|
Second, since plant stomata open less widely under elevated atmospheric CO2 this reduces transpiration and suppresses the role of plants in the hydrological cycle. |
|
A plant breathes through small holes, called stomata, found in its leaves. |
|
Structure, ontogeny, organographic distribution, and taxonomic significance of trichomes and stomata in the Cucurbitaceae. |
|
In addition, plants close their stomata and prevent further loss of interior moisture. |
|
The hotter plants grew more breathing pores, called stomata, which can allow water to escape. |
|
Most bennettitalean foliage shows xeromorphic features such as small, reflexed pinnae, sunken stomata, and papillae or hairs on the leaf surfaces. |
|
Also lacking stomata and a cuticle, lichens may absorb aerosols and gases over the entire thallus surface from which they may readily diffuse to the photobiont layer. |
|
The stomata are ranunculaceous and confined to the lower leaflet surface. |
|
The strongest line of supporting evidence is that liverworts are the only living group of land plants that do not have stomata on the sporophyte generation. |
|
The pull is the result of water surface tension within the cell walls of the mesophyll cells, from the surfaces of which evaporation takes place when the stomata are open. |
|
Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem, which are found in land plants. |
|
In most species, the upper surface of the leaves is uniformly green and shiny, without stomata or with a few on the tip, visible as whitish spots. |
