What is a cell?
All living things are made of cells. Most cells are too tiny to see with the naked eye.
What are the 3 basic ideas of Cell Theory?
1) The cell is a basic unit of life. 2) An organism can be as simple as one cell. 3) All cells are created from existing cells through a process called cell division.
Who invented the first light microscope?
Anthony Van Leeuwenhoek
Describe 3 parts and functions of the microscope?
1) Eyepiece: This is the lens that magnifies the specimen, usually by 10 times. 2) Stage: This is where you place a slide for observation. 3) Stage clips: These are used to hold a slide in position on the stage.
What are the functions of the mitochondria?
The power house of the cell. These organelles break down food particles and release their stored energy. The cell uses this energy to fuel all of it's activities. Mitochondria are surrouned by membrane.
What are the functions of the golgi apparatus?
A folded organelle that combines proteins made by the endoplasmic reticulm and delivers them to the rest of the cells and outside the cell.
What are the functions of the endoplasmic reticulum?
A folded organelle that makes proteins.
What are the functions of the nucleus?
A large organelle that is easy to see under a magnification. It controls the activities of the cell, such as growth.
What are the Functions Of the Lysosomes?
These organelles break down food and digest wastes.
Which green structure is unique for plant cells?
Chloroplasts
How do chloroplasts provide the cell with energy?
Through photosynthesis, the plant turns the suns energy into food.
Plant cells have some organelles that are different from those found in animal cells. List these orgranelles, and explain why you think these organelles are needed.
Chlorplasts: Because they contain chlorophyl which is needed for photosynthesis.
Are cell membranes permeable, selectively permeable, or impereable?
Selectivly Permeable
What are 2 types of cellular processes?
Diffusion and osmosis
List 3 safety steps you must follow when carrying a microscope?
1)Use 2 hands to carry the microscope. ! one the arm, one on the base. 2)Rotate the revolving nosepiece until the low power lense is in place. 3) use paper to clean the lenses.
