Limiting Factors – Photosynthesis Ep 3

The environmental conditions must be just right for photosynthesis to take place at the fastest possible rate. Today we're going to take a look at how light intensity, temperature and carbon dioxide (CO2) concentration can affect and limit the rate of photosynthesis. They will also affect plant growth, because photosynthesis produces glucose for respiration. Plants... Continue Reading →

Chloroplasts – Cell Organelles Ep 4

So far, all the organelles we have looked at (the nucleus, mitochondria, ribosomes and RER) are found in both animal and plant cells. Today's organelle, the chloroplasts, are only found in plant cells and some eukaryotic algae. Their main function is to carry out photosynthesis - the reaction that uses light energy to make glucose... Continue Reading →
