It is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.
Well, to make it easier, endoplasmic reticulum is actually a fancy way of saying "cellular highway". I will explain to you why. I always like to study BIOLOGY relating our activities and our stuff.
Okay, let's push aside cells. Let's think of us, humans. We can't stay in one place, we gotta moving all around the city. What do we use for moving around the city: either roads or sidewalks or footpaths.
Just like that, a cell also has a medium or road or a channel where all the substances can move around the cell. Well, its ER! So, from now on, everytime you are struggling with this difficult, L O N G word, just replace it with "cellular highway". The ER is like a water pipe, too. Water flows through it. Here, cellur substances flow through it. The ER is connected to the nucleus.
SUMMARY: 1# ER aka Endoplasmic Reticulum is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell. 2# Try thinking it easy: replace it with "cellular highway". 3# It is much like the roads or sidewalks, we walk on.
Decomposers are essential in breaking down organic matter into useful ones. For the nitrogen cycle, they break down bodies of dead organisms turning it into ammonia. Also, some bacteria break down nitrates turning into nitrogen which goes back to air.
ecent advances in stem cell biology have changed the current face of.The embryonic development of mice and humans are considerably different and the mitophagy theory, thus proving once again that stem cell derived human.
The knowledge obtained when scientists answer one question often generates other questions or proves useful in solving other questions. Scientists gather information and answer questions collectively known as the scientific method.
