Course: The Basis of Life: Understanding Human Cells
Cell survival – moving materials around
Cells need nutrients to survive. Cells sit in fluid that contains nutrients including water, oxygen, glucose and amino acids. The nutrients that are required by the cell need to cross …
Cells – the basis of life! Key learnings
This week we investigated the parts of cells and what they do, and how material is transported across the cell membrane. Cellular components are called cell organelles. Different organelles have …
Plant and animal cells
Both plant and animal cells share a few common cell organelles, as both are eukaryotes and the function of all these organelles is similar. However, there are some important differences. …
Active transport
Active transport requires energy. It could be compared to a ball moving up a hill. Active transport is the transport of molecules that require the use of energy, in the …
Passive transport
Passive transport requires no additional energy. It could be compared to a ball rolling down a hill. Passive transport mechanisms cause water and dissolved substances to move without using additional …
