Cell Diffusion

"Cell diffusion is a type of passive cell transport. In diffusion, molecules move from areas of high concentration to areas of low concentration in order to decrease the concentration gradient. Diffus ...

Calvin Cycle

"The Calvin cycle is the second step of photosynthesis which converts ATP into glucose for storage. It is also called the "light independent reaction" or the "dark reaction" because unlike the light d ...

Osmosis

"Osmosis is the diffusion of water molecules across a semi-permeable membrane  from an area of high concentration to an area of low concentration. In cells, osmosis occurs across the cellular membrane ...

Nucleus

"A cell nucleus is a membrane bound organelle which contains all the genetic information for a eukaryotic cell. This genetic information, or DNA, is stored in different forms depending upon the cell's ...

Mitochandria - Mitochondrion

"Mitochondria, also called mitochondrion, are organelles found in eukaryotic cells in which aerobic cellular respiration takes place. Mitochondria generate ATP which cells use for energy and have both ...

Asexual Reproduction

"Asexual reproduction is a type of reproduction found mostly in prokaryotes. Asexual reproduction doesn’t require fertilization and only one parent cell is needed to reproduce. In achaea and bacteria, ...

Anaerobic Respiration

Anaerobic respiration is the process of producing cellular energy without oxygen. Anaerobic respiration is a relatively fast reaction and produces 2 ATP, which is far fewer than aerobic respiration. A ...

Light Dependent Reaction

"The light dependent reaction is the first step of photosynthesis which converts light energy into ATP. The light dependent reaction takes place inside the chloroplasts along the thylakoid membrane." ...

Aerobic Respiration

"Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step i ...
