In flowering plants, plasmodesmata are narrow channels through cell walls that connect the cytoplasms of adjacent cells. An expl
anation of how plant cells communicate across cell walls will most likely refer to the diffusion through plasmodesmata of which of the following?a) Membrane-bound organellesb) Condensed, duplicated chromosomesc) Branched polysaccharidesd) Small, water-soluble molecules
Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.
The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.
The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.
Drinking salt water is harmful because it messes up the salt concentration in each of your red blood cells. It over loads the salt in it and causes the cell to swell up and burst due to it trying to let in more water to balance the salt concentration out.
advantages are of genetically modified plants are the desired traits it results in but also they well-grown fruits and vegitables will be plump, ripe and delicious.
The main difference between pyrogenesis and setting garbage on fire in a landfill is that pyrogenesis process occurs on the surface whereas garbage on fire in a landfill occurs inside the soil at certain depth. Pyrogenesis is an extreme thermal process that converts organic matter into gas made up of hydrogen and oxygen whereas garbage on fire in a landfill decomposes garbage that breaks down materials in simpler substances.
In DNA, there are four possible nitrogen bases – adenine (A), guanine (G), cytosine (C), and thymine (T). In DNA, nucleotides combine to form two long chains that intertwine with each other, like a ladder that has twisted into a spiral.
