how do you memorise parts and functios of animal cell and plant cell quickley
by parts i mean like, golgi, lysosome, mitochondrion, ER, ribosomes, cell membrane, vacuole ect......

First of all, the best way to MEMORIZE organelles (or parts as you describe them) is to use flash cards and test yourself.
Organelles that Control the Cell:

Nucleus - The control center of the cell. It controls many of the chemical reactions that occur within the cytoplasm (defined below under miscellaneous). It also contains all the genetic material that determines the cell’s characteristics.

Membrane – Surrounds many of the organelles of the cell (except for ribosomes in this list) and also the entire cell itself. The membrane that surrounds the entire cell is called the cellular membrane. It controls what goes in and out the cell or each of the organelles.

Organelles that Manufacture:

Ribosomes - Where proteins are created that the cell needs

Golgi Body – Finishes processing the proteins made by the ribosomes and “packages” them for transport to where they are needed in the cell.

Rough Endoplasmic Reticulum – It is “rough” since it has many ribosomes attached to it. It has two functions: one is to make more membrane and another is to make proteins, such as antibodies.

Smooth Endoplasmic Reticulum – It is “smooth” since it does not have ribosomes attached to it like the rough endoplasmic reticulum. In cells for different functions, it is responsible for making the proteins the cell needs to perform many functions.

Organelles that Breakdown:

Lysosomes – Digests the cell’s food and wastes. The digested waste can then be used to make new parts of the cell.

Peroxisomes – Breaks down H2O2, a poisonous by-product of some cellular processes.

Vacuole – In plant cells, it is like a very large lyosome. It can break down old and damaged parts of the cell and also store chemicals that the cell needs.

Organelles that Make Energy:

Chloroplasts – Only in plant cells, these organelles convert solar energy to chemical energy that the cell can use.

Mitochondria – The energy center of the cell. Changes food energy into chemical energy the cell can use.


Cytoplasm - The fluid of the cell that all the cell’s organelles are contained within.

nucleus: doesn't drive many processes, at least not the metabolism taking place in cytoplasm!

rough ER: they definitely do not produce lipids!

smooth ER: they definitely do not produce proteins!

Cis or trans? That's what matters.

This MIGHT help, but I haven't actually tested it - it's won all sorts of awards, though"
