Plant cells have chloroplasts and cell walls where animal cells do not.

What are the two main differences between plant cells and animal cells

• Animal cells have a cell membrane, plants do not.

• Animal cells have mitochondria, plant cells do not.

• Plant cells are eukaryotic, animal cells are not.

• Plant cells have large water filled vacuoles, chloroplasts and a cell wall where animal cells have small food vacuoles, with no cell wall or chloroplasts

Cell transport, that is, the movement of molecules across the cell membrane, involves homeostasis (i.e. balance in the cell). Notice that the movement of molecules goes from a high concentration to a low concentration here, this is considered passive transport. Active transport would be going from low to high.

What would you call the process that is happening here?

• energy is converted as well as new molecules are formed

• new molecules are formed and ATP is produced

• Active transport is required and homeostasis (balance) is achieved

• Molecules are moved and homeostasis (balance) is achieved
