Sentences with phrase «central cell»

We found that 12.5 % of peripheral cells yet only 0.6 % of central cells were BrdU - labeled in flank retinas (2,063 cells from ten flank retinas were counted, p < 0.001).

Reproduction of flowering plants occurs within a plant's ovule by the fertilisation of both the egg and a larger central cell by two sperm cells.

Transmission electron microscopy of the unfertilized ovule revealed a very thin cell wall between the synergid cell and central cell wall, which was assumed to be necessary for rapid disintegration of the cell walls.

A. WT astrocytes (green) secrete factors that promote the development of healthy neurons (green): neuron has a large central cell body, extends many long thin dendritic processes, and receives numerous syaptic connections (black).

But as a statement of the company's design direction it's certainly interesting, and with electric propulsion, autonomous tech and a carbonfibre central cell, there's a strong technological aspect too.

I know John Barker had some reservations when he drove it in evo 234, but it sounds like a phenomenal piece of engineering, right down to the entirely appropriate and legitimate use of carbonfibre for the cleverly designed central cell.

Bill McKibben — journalist, gadfly, Bernie Sanders supporter, and briefly an inmate of Washington, D.C.'s Central Cell Block — is one of America's foremost environmental activists.

The tanks of electroactive materials can be made as large as needed — increasing total amount of energy the system can store — or the central cell can be tweaked to release that energy faster or slower, altering the amount of power (energy released over time) that the system can generate.

RIMB also urged Roche to set up a central cell - culture facility, again providing the director and space.

Using live imaging techniques, the team found that cell fusion, which is induced by the fertilisation of the central cell, rapidly dilutes the contents of the persistent synergid cell.

During this process, the synergid cell dies and degenerates, and the sperm cells migrate to the egg and central cell.

Once fertilised, the egg cell becomes the embryo while the central cell becomes the endosperm that nourishes the embryo.

The two sperm cells independently fertilize the egg cell and the central cell to produce the embryo and the endosperm (a tissue that surrounds and nourishes the embryo), respectively, which eventually develops into a seed.

The mature ovule in most flowering plants, including Arabidopsis thaliana, contains a seven - celled embryo sac consisting of two synergid cells, one egg cell, one central cell and three antipodal cells.

«We continued to look into this phenomena to gain mechanistic insight and found evidence of a unique three - step mechanism for polytubey block, where the egg cell and the central cell coordinately play key roles in eliminating the persistent synergid cell by cell fusion and subsequent nuclear disorganization.»

SE fusion, which is induced by fertilization of the central cell, causes rapid dilution of the pre-secreted pollen tube attractant in the persistent synergid cell.

Johnson said his lab will focus on the evolution of mechanisms underlying double fertilization, the process by which flowering plants not only fuse sperm and egg, but also where a second sperm fuses with a central cell that develops into much of the rest of the seed (including the «endosperm» that provides nutrition and protection for the embryo).

The interior design of the 2014 Alfa Romeo 4C Spider Concept is characterized by the eye - catching carbon fiber found in the central cell that allows for proper weight distribution.

Specifically, the carbon fibre of the central cell immediately stands out in the interior, left in full view to enhance the sense of low weight, technology and uniqueness of the car.

Specifically, the carbon fibre in the interior immediately stands out, used to make the central cell, which has been left in full view to enhance the sense of light weight, technology and uniqueness.

He has been called «the Matt Drudge of climate denial», the «King of the skeptics,» and a «central cell of the climate - denial machine.»
