This week in science, we learned about plant and animal cells and their differences and similarities. We learned about them by making four slides: potatoe with blue stain; potatoe with with red stain; potatoe with non-stain; and grass. We then viewed each slide under both high and low magnification. I noticed that in all of the potatoe slides, in both high and low magnification, the cells are mainly made up of circles, small and large. The grass, however, did not have many circles in its structure. It is important to know about animal and plant cell structures because we are composed of and surrounded by them.
We also learned more about cells by learning about their structures and functions by discussing them with our class and doing some research, and finally making a chart:

• Structure-Function
• cytoplasm-holds everything in place
• nucleus-controls everything that goes on in the cell
• cell wall-protection, structure
• etc.

This is important to know because throughout our science careers we will constantly be dealing with cells. Also, we are surrounded by and composed of them.
