In diffusion, the molecule is moving from the container with higher concentration into the lower concentration, resulting in a similar concentration between both containers in the end.
But in osmosis, the molecule can't move. The molecule can attract water, so the container with higher concentration will attract more water. This will cause the water to move, not the molecule. The water will move from the container with lower concentration into the higher concentration. The result after the osmosis should be both containers have similar concentration, just like diffusion.

<u>Similarities</u>

Diffusion and osmosis are both examples of passive transport.

They transport substances down a concentration gradient.

<u>Difference</u>

Diffusion is the movement of solute particles down a concentration gradient. Osmosis is the movement of water molecules down a concentration gradient.

<h3>FURTHER EXPLANATION</h3><h3>Active and Passive Transport</h3>

Passive transport is the movement of particles through a membrane which requires no extra energy. It happens spontaneously because there is an imbalance in the amount of solutes  or difference in concentration inside and outside the membrane. In order to reach equilibrium or a state where the amount of solute or concentration on both sides is the same, some substances have to cross the membrane.

When substances move from a region of high concentration to low concentration, it is said that the substances are moving down a concentration gradient. This process is spontaneous meaning it does not require energy to occur. The opposite is true for active transport which requires additional energy for it to happen.

<h3>Movement of Substances</h3>

In diffusion, solutes move from a concentrated area to a less concentrated area.

In osmosis, the water molecules move from an area with more water molecules (lower concentration of solutes) to the area with less water molecules (higher concentration of solutes).

True or false: Active transport is required to more particles from an area of lower
LUCKY_DIMON [66]
That is true. Active transport goes against the concentration gradient. Particles want to move from higher concentration to lower concentration and even out, but active transport makes them move against that.

Can someone help match these defenitions.
luda_lava [24]

The right matches are:

1. nuclear envelope  is matched with b.

2.centriole  is matched with  a.

3.interphase is matched with j.

4.furrowing  is matched with h.  

5.anaphase  is matched with g.

6.spindle apparatus is matched with f.

7.chromatin is matched with i.

8.haploid is matched with c.

9.meiosis is matched with e.  

10.homologous chromosomes is matched with d.


Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.

Which organelle is responsible for sorting and packaging proteins for storage and/or secretion from the cell?
HACTEHA [7]
Ribosomes and Endoplasmic Reticulum. Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA. So, the answer has to be A and C.

S it possible to produce malleable cast iron in pieces having large cross-sectional dimensions?
ivolga24 [154]
IT IS NOT POSSIBLE to produce malleable cast iron in pieces having large cross sectional dimension. This is because, iron has a very rapid cooling rate and it will not be possible to achieve this rate at different cross sectional areas in a sheet of iron.
