Energy!

This post has the most monstrous image I’ve made to date.  I hope it will become more popular and useful than my current heavy hitters the cell and even Louis Pasteur’s experiment of spontaneous generation, which I’ve seen make the top ranks of both Google and Bing image search! In this image, I’ve covered energy [...]

Mitosis

The M phase of the cell cycle is the process known as mitosis. Some scientists classify cytokinesis as separate from mitosis, but still in the M phase. Mitosis is split into 4 distinct phases plus cytokinesis. Prophase is the longest phase of mitosis. Chromatin condenses to form chromosomes, centrioles move to the poles, spindles form, [...]

Cell Division – An Intro

When cells grow, the run into a problem.  As the cell grows in size, their surface area to volume ratio changes.  As it turns out the higher the volume is in relation to the surface area, the more difficult it becomes to diffuse enough material into the cell.  Think of a city with 1 road. [...]

Cellular Respiration

Cellular respiration is not exactly, but can be roughly viewed as, the reverse process as photosynthesis. Oxygen and glucose combine to breakdown and reassemble as carbon dioxide, water, and energy.

Photosynthesis

Plants are autotrophs, and today I’d like to focus on how plants get the energy they need. Plants need the following things to get energy to live: Water (H2O), Carbon Dioxide (CO2), Sunlight. The process of converting H2O and CO2 in the presence of sunlight into energy is called photosynthesis.

Energy

Autotrophs make their own food and heterotrophs must consume food from an outside source. ATP is the energy source of cells.
