Chapter 2 - Overview Of Cell And Plasma Membrane Flashcards
(1) consist of a plasma membrane, an inner cytoplasm with numerous organelles, and other cellular structures.
- Cells
Cytosol
The fluid portion of a cell.
The (1) is the genetic center of cells and consists of fluid karyoplasm, chromatin (which contains (2)), and the nucleolus.
- Nucleus
- DNA
What 3 things does the cytoskeleton consist of? It is also involved in maintaining cell (4), fixing (5), and directing some (6) activity.
- Microtubules
- Intermediate filaments
- Microfilaments
- Shape
- Organelles
- Cellular
Mitochondria
The energy producing structures of the cell.
Golgi apparatus
Assembles complex biomolecules and transports them out of the cell.
Proteins are made in the cell by (1). If (1) are found by themselves in the cytoplasm they are termed (2). If (1) are found attached to the rough endoplasmic reticulum they are (3).
- Ribosomes
- Free
- Bound
The (1) endoplasmic reticulum is in charge of making cellular proteins. The (2) endoplasmic reticulum is in charge of making lipids and breaking down (3) cellular materials.
- Rough
- Smooth
- Toxic
(1) are cellular sacs that hold liquids.
- Vesicles
(1) vesicles ingest material into the cell.
- Phagocytic
Lysosome
Contains digestive enzymes.
Peroxisomes
Degrades toxic hydrogen peroxide in cells.
Centrioles
Microtubules that are grouped together and are involved in cell division.
The (1) is composed of a phospholipid bilayer. This bilayer has (2) molecules on the outside and inside of the (1) and a (3) layer in-between.
- Plasma membrane
- Phosphate
- Lipid
(1) molecules occur within the membrane, and depending on their concentration they can make the membrane stiff or more fluid
- Cholesterol
