Cell Types and Cell Theory
This organelle is composed of a phospholipid bilayer
Cell membrane or plasma membrane
What two organelles are found in plant cells, but not animal cells?
Chloroplasts and Cell Wall
This jelly-like fluid filling inside of the cell is mostly made of water
cytoplasm
Cells that contain membrane bound organelles are called
eukaryotic
This organelle is a folded membrane connected to the nucleus- it has ribosomes attached to its surface
Rough ER
This organelle controls all the other organelles in the cell and contains DNA
Nucleus
This organelle is much larger in plant cells and helps give them structure (via turgor pressure)
Central vacuole
The invention of the __________ led to the development of cell theory.
microscope
what is an example of a prokaryotic cell?
These are hair-like extensions of the cell’s cytoskeleton that allow for movement
Cilia and flagella
this organelle is responsible for cellular respiration, which is when food is turned into energy.
Both plant and animal cells contain _____________________, which is the site for protein synthesis
What is the function of smooth ER
produces lipids
what type of cells are human cells? (prokaryotic or eukaryotic)
This organelle is found only in plant cells and some protist cells and is double-membrane organelle containing chlorophyll
Chloroplast
this organelle contains digestive enzymes that are used to break down waste and other items the cell no longer needs.
All cells (eukaryotic/prokaryotic/animal/plant) contain what organelles
Cell membrane, ribosomes, cytoplasm
What is the function of the cytoskelton
•Provides shape and support
•Helps move organelles throughout the cell
name the three different parts of the cell theory.
1. All living things are made of cells.
2. Cells are the basic unit of life.
3. Cells come from preexisting cells.
This organelle is a stack of flattened membrane sacs. It modifies, sorts, and packages proteins and sends them to their final destinations inside or outside the cell
This organelle produces ribosomes
nucleolus
Animal cells, and not plant cells, contain ___________________, which aid in cellular division.
What are the levels of organization?
Cell, tissue, organ, organ system, organism
