Definition
Allows some materials to pass, such as, nutrients and water but not others
Cell Membrane
Make protein for the cell
Ribosomes
What are cells?
The building blocks of living things
A plant cell is a circular structure
False. A plant cell is more of a "boxed-like" structure
What is an organelle?
Specialized structures that helps plant and animals stay alive. Each organelle preforms a specific function.
The "brain" of the cell
Nucleus
Provides extra support and structure for the cell
Cell Wall
What can all cells do?
Take in nutrients and turn them into energy
Most germs that can make us sick are made up of one cell
True!
What is photosyntheisis?
The process that plants use to make the glucose they use as food
Temporarily store different substances needed by the cell
Vacuole
Helps with cell division
Centrioles
Living things that are made up of one cell are called?
Unicellular
Prokaryotic cells are about ten times larger than Eukaryotic cells
What organelle helps with the process of photosynthesis?
Chloroplast
Internal delivery system for transporting materials the cells needs
Endoplasmic Reticulum
Uses oxygen to transform food into energy
Mitochondria
An example of a prokaryotic cell is...?
Bacteria
Plant cell has one very large vacuole
True!! Animal cells have multiple small vacuoles for nutrient and water storage.
Explain Mitosis?
When a cell makes a copy of its genetic material and then splits into two cells. The DNA remains identical and the cell has reproduced.
Gel like fluid, mostly made up of water that takes up most of the space in the cell
Cytoplasm
Help package materials from the endoplasmic reticulum and distribute them around the cell or outside of it
Golgi Bodies
How do most cells reproduce?
Mitosis
All plants cells have chloroplast?
False. Not all plants are green. Chloroplast and the chlorophyl they contain are what gives plants their green colour.
Name three things that cell theory tells us
Cells make up all living things, new cells are produced by existing cells and all life's activities take place in cells
