He constructed the higher powered compound light microscope
What did then Leewin Holick do in 1674
He observes micro organisms
What did swan and slide in state in 1838
They stated that all living things are made out of cells and carry out functions
What did swan down
Animal cells
What did Verchow do in 1839
He proposed cells growth and divide
What are all living things
Made up of cells, responded to the environment, have the ability to reproduce, move, grow and develop
What are the three concepts to the cell theory
Every living thing is made up of one or more cells, cells carry out the functions needed to support life, cells come from only other living things
What is the nucleus
Function: holds the DNA Parts: nucleosis: dark spot in the middle of the nucleus that helps make ribosomes
What are ribosomes
Protein zones, function: makes proteins, found in all cells, prokaryotic and eukaryotic
What is the endoplasmic reticulum
The roads, function: the internal delivery system of the cell
What is the Golgi complex
The shippers, function: packages modifies and transport materials to different location inside/outside of the cell, appearance: stack of pancakes
What is mitochondria
The powerhouse, function: energy for Mason, breaks down glucose to make ATP, ATP: is the major fuel for all cell activities that require energy
What is a lysosomes
The garbage men, removes waste from inside the cell
What is a vacuole
Function: stores water, also in animals, but much smaller, this is what makes lettuce crisp, no water, plant wilts
What is a chloroplast
Function: traps energy from the sun to produce food for the plant cell, green in color because of Clore Phil, which is a green pigment
What is a cell wall
Function: provide support and protection to the cell membrane, found outside the cell membrane in bolded plant cells
What are organelles
Small structures inside of a cell that perform essential functions
What is a level of body organization
Within multicellular organisms there’s division of labor. Space each part of the body has a job to do and as each part doesn’t special job, it works in harmony with all of the other parts
What are the levels of body organization from simplest a complex
Cells, tissues, organs, systems, organisms (or cotso!)
What are cells
The basic unit in the human body, all cells are specialized functions, examples are nerve cells, bone cells, and blood cells
What are tissues
A group of specialized cells that work together to perform the same function
What are the four basic types of tissue in the human body
Nerve tissue: carry signals back-and-forth from brain to body, muscle tissue: contracts and extends making body parts move, epithelial tissue: cover surface of body and organs, connective tissue : connects parts of the body and provide support
What are organs
A group of different tissues that work together to perform a specific function, it’s task is more complex than tissues, examples are heart is made of muscle and connective tissue used to pump blood throughout the body
What is the organ system
Two or more organs that work together to perform a specific function, each organ system has its own function but the systems work together depends on what another, there are 11 different organ systems in the human body
