Cytoplasmic Streaming Flash Mini Game

Cytoplasmic Streaming Flash Game

The process of organelles and nutrients rapidly moving around a plant or fungal cells is known as cytoplasmic streaming. Just as water is constantly moving in a lake that we may never notice, organelles are constantly moving inside of plant and fungal cells. I have created flash mini game to streamline learning about how cytoplasmic streaming transports nutrients around a cell. Transporting Nutrients (Flash …

Smoking Black and Mild vs Cigarettes

Cigareete Black And Mild

Two popular sources of tobacco smoke are the Black and Mild and Cigarettes (many brands). As a college student who quit smoking I went to search for factual information on the 2 most popular types of tobacco that I saw people smoke.

How to Memorize the 12 Cranial Nerves

The 12 cranial nerves may be difficult to memorize at times so I have came up with a method to help memorize and reinforce the names and functions of the 12 cranial nerves while I was taking Anatomy and Physiology.

Exons Simplified

What are Exons? In preRNA there are exons and introns. Exons are the sequence of nucleotides that are connected to each other after the process of alternative splicing. “In a nut shell” , exons are the nucleotides needed to produce the mRNA while introns are the “non-coded” sequences that are removed during the splicing process. Function Each of the exons …

The Properties of Water We Cant Live Without

Is there a coincidence that the most abundant molecule on earth (water) has special properties that we could not live without. Water has the amazing ability to: absorb heat without changing temperature remain more dense than its solid counterpart (ice) and pull neighboring water molecules as its sucked up the roots of plants Here is an explanation why we can not live without these special properties of …

Introns Simplified

So What Are Introns? As DNA is being transcribed into RNA there are often regions of “junk” DNA that are removed before the final (mature) mRNA is produced. These “nonprotein-coding regions” are called introns. The other DNA that is transcribed into RNA or “protein-coding regions” are called exons. Introns are the “junk” DNA bases found between this sequence. To learn more …

Passive vs Active Transport Simplified

Overview The simple difference between passive transport and active transport is the energy source they use to move molecules across a membrane. [table caption=”Passive vs Active TRansport”] Let Us Compare,Passive Transport,Active Transport Needs Cellular Energy,No,Yes Source of Energy, Concentration Gradient, ATP or Concentration Gradient Direction of Flow, High to Low Concentration,Low to High Concentration [/table] Passive Transport Passive Transport takes no energy and moves …

What is Active Transport Simplified

Primary Active Transport

Active Transport can be simplified if you understand that it is the opposite process of  what cells can do without using energy. Without using energy chemical substances can freely move from higher to lower concentrations (passive transport). Active Transport on the other hand must use energy to move chemical substances from lower to higher concentrations. 2 types of Active Transport The two types …
