The Green Cell (City)
What is a Cell?
A cell is the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Although, there are more things inside a cell than these!
Organelle #1: Nucleus
A membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction.
The nucleus is in the middle of the cell, and is one of the most vital, if not most important, part of a cell. The nucleus can be compared to the Town Hall of a city. It helps the city grow, stay in order, and keeps information used to make decisions for the city.
Organelle #2: Mitochondria
The cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP.
The mitochondria is similar to a power plant.
Organelle #3: Endoplasmic Reticulum
A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.
The Endoplasmic Reticulum has rough and smooth textures. The ER is like roads or a post office, because it is used as transportation throughout the cell.
Organelle #4: Ribosomes
Cell organelles composed of RNA and protein; the site of protein synthesis.
Ribosomes are like factories or farms because they provide protein such as a factory/farm would to the people.
