J.R. Zuang Cells Mixbook - Page Text Content


1: Contributions of Four Scientists | Robert Hooke used a compound microscope in 1665 to observe some cork. all he saw were dead cell walls which reminded him of the "cells" monks lived in. The name stuck and we call them cells to this day. Mattias Schleiden also saw plant cells under a microscope, and consulted with Schleiden in 1838. Theodor Schwann was a German biologist who was the first to discover animal cells in 1839. Rudolph Virchow was the first to state, in 1855, that all living cells came from preexisting cells. Together these scientists developed cell theory.

2: a bumpy bus ride | There are three parts to cell theory.The first is that all living things are made of one or more cells. The other two are that cells are the basic unit of structure and function in an organism, and that all cells come from other cells. | Cell Theory

3: Types of Cells | This is an Eukaryotic cell. It has a nucleus, which it uses to contain DNA. It has more organelles than a prokaryotic cell. | This is a prokaryote has no nucleus, and the only organelles it contains are ribosomes.

4: Types of Cells | Animal cells are what make up every animal and person. Since they don't have a cell wall they can be a variety of shapes. The main purpose of an animal cell is helping your body work like one. | Plant cells have a cell wall, chloroplasts and their vacuoles are used to contain water. Their purpose is to give plants structure cause they don't have bones.

6: Ten Cell Structures | This is cytoplasm. It is liquid that all of the organelles are suspended in. | This is the Cytoskeleton. it is a protein chain that provides structure for the cell. | This is a cell wall, it provides structure for the plant and give extra protection to the cell.

7: This is a central vaccuole. Its purpose is to store things. In plant cells, it takes up 30%-80% of the cell, and stores water. In animal cells it is smaller, and isolates and contains waste. | This is the golgi apparatus. Its purpose is to package proteins for transporting in the cell and to other cells. | This is the mitochondria. Its purpose is to break down proteins for energy | This is the centriole. It's purpose is to produce microtubules. | Which brings us to our next point. These are the microtubules. They provide shape and structure for the cell, and are part of the cytoskeleton.

8: This is the endoplasmic reticulum. It is a system of membranes that move proteins and other substances throughout the cell. | Most of the ribosomes in the cell are attatched to an ER. This part of the ER is called the smooth endoplasmic reticulum | TEN CELL STRUCTURES

9: CELL MEMBRANE | The cell membrane is the thin outer layer of the cell. It holds parts of the cell together and protects its contents

10: HOMEOSTASIS | Homeostasis is how a system maintain a consistent condition for the cells to live in. It is needed in the human body so that cells and organs may function properly without having problems. Sign of Homeostasis are Sweating, Fever, Shivering, and Coughing.

14: There was more than one occasion where we had to be resourceful and live on the streets because we missed a train or couldnt find a hostel.

15: brian | kristina | megan | jon

17: Backpacking took us to many beautiful verdant places. Our granola bars kept u alive during long walks.

18: Gepetto's Shop

19: There were many street artists who were very talented. Too bad our backpacks had no space for artwork.

20: being silly

21: ...and sometimes bad.

23: Eating gelato, meeting strangers, living in hostels, walking along coastlines, sleeping on trains, going to festivals, eating authentic foods, learning transportation systems, buying groceries; It was all a great experience, despite the rainy days, getting lost, and taking trains in wrong directions. Immersing in different cultures taught us a lot and opened our eyes to a little bit more of the world around us.
