illustrate how the self sealing bubble membrane helps to illustrate the passage of molecules through a cell membrane and the property of selective permeability

Answers

Self-sealing bubble membranes help to illustrate the passage of molecules and the property of selective permeability in that they are an example of how something can be semi-permeable and allow only some substances to pass.

When we mention a membrane, we refer to the selective barrier that protects cells from the environment. Within this barrier, lie certain proteins that serve as a kind of "tunnel" for the passage of very specific substances. This, along with a few other mechanisms are what gives a membrane the title of being semi-permeable.

This is because semi or selective permeability is the ability to allow the passage of very specific substances despite being a sealed barrier. Self-sealing bubble membranes share this ability by allowing some substances, like specific gases, to enter the bubble while others will remain on the exterior of the sealed barrier.

Would a plant be able to survive if the ground tissue was damaged? Explain your answer.

Answers

Given what we know, we can confirm that with damaged ground tissue, a plant will most likely not be able to survive.

What we know about ground tissues in plants.The ground tissue forms an abundant part of all plant tissues. This tissue includes all plant tissue that is neither vascular nor dermal.This means that ground tissue covers a wide variety of functions. Two primary and important functions are the storage of sugar and water.

Therefore, given the vital role of this tissue in plants and its function in storing "food" and water, we can confidently say that a plant with damaged ground tissue will not be able to survive for long.

The mitochondria

The Krebs cycle or citric acid processes in the mitochondrial matrix yield a substance called NADH. Adenosine triphosphate is then produced from NADH by enzymes included into the mitochondrial inner membrane (ATP).

What is the main role of mitochondria in nutrient energy?

Organelles, or “tiny organs,” are what mitochondria are. They generate ATP (adenosine triphosphate), a chemical that is used by the cell to power the various tasks it must perform, as a source of energy.

The creation of cellular ATP by oxidative phosphorylation is undoubtedly one of the activities of mitochondria, but they also play significant roles in ion homeostasis.

Various metabolic pathways, apoptosis and programmed cell death, as well as the production and consumption of ROS.

Therefore, mitochondria transform nutrient material into an energy form that is used by the cell.
