There are _______ characteristics of life.
What is six?
Are the basic unit of life for all living things
What are cells?
The smallest structural and functional unit of an organism. Our bodies are made of them.
What is a cell?
One of the technologies developed has given us access to extensive knowledge regarding cells.
What is a microscope?
An individual animal or plant can be single or multicellular, classified into groups or kingdoms
What is an organism?
This type of cell refer to animals and humans, with organelles and nuclei.
What are eukaryotic cells?
This type of cell contains chloroplast, and rigid cell wall and is only found in this specific type of cell.
What is a planet cell?
All cells in the body, EXCEPT for reproductive cells.
What are somatic cells?
All living things are composed of cells, cells are the basic unit of structure and functions in living things, and all cells come from preexisting cells.
What is cell theory?
TWO answers: Manufactures its own food -or- obtains food from eating other organisms
What is autotroph and heterotroph?
Cells do not have a membrane-bound nucleus, smaller in size, and have a prefix that means "before"
What are prokaryotic cells?
Found in both plant and animal cells, large oval shaped in the center, the "control center" or brain of the cell.
Somatic cells result in two cells that are exactly the same as the parent cell. Two new cells are called diploid cells.
What is cell division by mitosis?
Observed bark of cork trees under a microscope, thought the object looked liked individual rooms in a monastery, which he called cells.
Who is Robert Hooke?
An organism's ability to maintain steady internal conditions when outside conditions change

What are vacuoles?
The chromosomes have reached the poles and begin to unwind, two nuclear envelopes from, and cleavage furrow is visable.
What is telophase?
Robert Hooke, Anton van Leeuwenhoek, Matthias Schleiden and Theodor Schwann.
Who founded/discovered/proposed cell theory?
