Characteristics Of A Cell
The smallest structural and functional unit of a living organism
What is a cell?
They are organisms that are made up of only one cell
What is an unicellular organism?
This is the largest organelle in a cell.
What is the nucleus?
Eukaryotic and prokaryotic
What are the two types of cells?
This is stored during photosynthesis
What is energy?
glucose is broken down during this process.
What is glycolysis?
An organism made up of many cells
What is a multicellular organism?
A protective layer around the cell that controls the materials such as water and oxygen that go in and out of the cell
What is the cell membrane?
Lipids in a cell control the function of this cell part.
What is the protective membrane?
Carbon dioxide, water and energy are the result of this.
What is respiration?
The first man to look at cells and the man who built the microscope
Who is Robert Hooke?
Schleiden, Virchow or Schwann determined that all plants are made out of cells.
In 1838, what did Matthias Schleiden do to contribute to the research of cell theory?
The region enclosed by the cell membrane where all the fluid and organelles are stored
These break down material in the cell.
What are lysosomes?
Passive transport does not use this.
What is energy?
DNA, cellulose and cholesterol are these.
What are macromolecules?
Schleiden, Virchow or Schwann discovered that all animal tissues are made out of cells
In 1839, what did Theodor Schwann do to contribute to the research of cell theory?
A genetic material in nucleus that provides instructions for the cell and is inherited from the parents.
What is DNA?
A cell's vesicles release their contents outside the cell and proteins are released.
What is exocytosis?
Molecules from an area of higher concentration move to an area of lower concentration.
What is diffusion?
All organisms are made of one or more cells, the cell is the basic unit of all organisms, all cell come from cells
What is the cell theory?
Schleiden, Virchow or Schwann discovered that all cells are formed from other cells
In 1858, what did Robert Virchow do to contribute to the research of cell theory?
A human cell is made of these macromolecules that provide energy (need 2).
What are lipids and carbohydrates?
The process of converting energy in food molecules into a usable form of energy called ATP.
What is cellular respiration?
The organelle that is only in plants, where photosynthesis occurs
What are chloroplasts?
