Which cells are responsible for the movement of photosynthates through a plant?
jasenka [17]

Answer:

sieve-tube elements, companion cells

Explanation:

Sieve-tube elements and companion cells are responsible for the movement of photosynthes through a plant.

The sieve tube elements are shorter (almost organelle-free) living cells, placed end to end, forming the sieve tubes. Their transverse cell walls are called sieve plaques that make connections between cells and through openings called sieves establish the connection between the cytoplasm of adjacent cells.  Each sieve is coated with calose (glucose polymer), which in winter can completely clog the vessel and then dissolve in spring. When infections occur or the vessel is parasitized, it can also be clogged with callose.

Companion cells are specialized parenchymal cells, which contain all the components that exist in living cells, including the nucleus, are the cells most closely linked to the sieved tube element. The Screened Tube Element and its companion cells are related in development, are derived from the same mother cell, and have several cytoplasmic connections to each other. Due to the many connections, the potential function of the companion cells is to release substances into the sieved tube element and, when the nucleus is absent, to include information molecules, proteins and ATP. When a screened element dies, its companion cells also die, which is a demonstration of this interdependence.

Winding mills are made on hills. Why?​
Leni [432]

Answer:

Winding mills are made on hills because of air flow and currents.

Explanation:

Winding mills capture wind to turn blades and produce energy. In order to do so, it needs winds! Strong winds, in order to turn the blades. You will notice that if you ever scale a mountain or go higher, it starts to become windier/the wind blows harder.

If the wind mills are placed higher, it can capture these windier conditions, thus moving the wind blades to produce energy. The higher the hill, the stronger the wind current, the more energy it produces.

An investigator attempting to replicate Pasteur's swan-necked flask experiment has boiled a hay infusion for 1 hour. However, sh
blsea [12.9K]

Answer:

Hay infusion refers to an amalgamation that can be formed by taking samples from different sources like rivers, lakes, ponds, and others. It is one of the best procedures that can elevate the density of the bacteria cell at any specific time interval.  

In the given case, even after boiling hay infusion for one hour, growth was observed in the flask after one day. It can be due to certain factors like the hay infusion may have been comprising some endospore, which is resistant to heat or may comprise some kinds of bacteria that can withstand high temperatures.  

Because of which, even after heating the infusion for one hour, it did not get influenced by the heat and got the chance to grow when it got optimum temperature again at the time when the sample was left as such.
