Science: Animal and Plant Cells

 Hi there!

Today I will be sharing my knowledge between the difference of animal cells and plant cells. 

Here is an image of an animal cell:


Cytoplasm - Cytoplasm is a jelly-like material which surrounds all the cell parts inside of the cell membrane. Cytoplasm was considered to be a fluid-like substance. However, after recent research it is similar to glass-like liquids. 
Nucleus - The nucleus is a part of every cell. The nucleus is a 'storage unit' which holds the chromosomes, DNA and genes of the animal. 
Cell membrane - The cell membrane is a thin layer of protein and fat which protects and keeps all of the cell parts inside. It helps support the cell and give it integrity. 
Mitochondrion - Mitochondrion or mitochondria (plural) is a rod-shaped organelle. They are called the power house of the cell, because they play a crucial role in releasing energy. 

Here is a plant cell:



Cytoplasm - Cytoplasm does differ from an animal cell. As mentioned above, cytoplasm is a jelly-like material which fills a cell and protects and supports organelle in the cell.  
Nucleus - Every organism has a nucleus, plants aren't excluded from this! The nucleus stores chromosomes, DNA and other genetic material.
Cell membrane - The cell membrane is still a thin layer of fats and protein which encase the organelle of a cell. It makes sure everything in the cell doesn't leave and become damaged. 
(Cellulose) cell wall - The cell wall is the outmost part of a plant cell. It gives the cell structure, as opposed to an animal cell which doesn't have much integrity. It separates the exterior environment from the organelles in the interior of the cell.  
Mitochondrion - Look above for description. 
Permanent/large vacuole - The term 'vacuole' means 'empty space'. In a plant, a vacuole cell quite large, taking up to 80% of the cell up. The vacuole stores nutrients to feed the plant, it expands and shrinks regarding if it has enough water. We can see this in the form of a plant drooping and looking lifeless (vacuoles are shrinking) or a plant which looks full of life (vacuoles are expanded). The vacuole also help give structure to the cell. 
Chloroplast - Chloroplast is the organelle which makes green plants green. It is responsible for photosynthesis and are found in the leaves of a plant. 

Thanks for reading!
