cells Flashcards
It is made of protein and RNA
RIBOSOMES
Sites of protein synthesis
RIBOSOMES
Found at two locations, free in the cytoplasm
RIBOSOMES
It is attached to rough endoplasmic reticulum.
RIBOSOMES
Material outside the nucleus and inside the plasma membrane.
CYTOPLASM
Fluid that suspends other elements
CYTOSOL
Metabolic machinery of the cell.
ORGANELLES
Non-functioning units.
INCLUSIONS
Carry out all chemical activities needed to sustain life.
CELLS
Building blocks of all living things.
CELLS
Groups of cells that are similar in structure and function.
TISSUES
ANATOMY OF THE CELLS
- Cells are not all the same.
- All cells share general structures.
What are the three main regions of the cells?
Nucleus, Cytoplasm, and Plasma Membrane.
Control center of the cell.
NUCLEUS
Contains genetic material (DNA)
NUCLEUS
What are the regions of Nucleus?
Nuclear Membrane, Nucleolus, Chromatin.
Barrier of nucleus.
NUCLEAR MEMBRANE
Consists of double phospholipid membrane.
NUCLEAR MEMBRANE
Contain nuclear pores that allow for exchange of material with the rest of the cell.
NUCLEAR MEMBRANE
Contains one or more nucleoli.
NUCLEUS
Sites of ribosome production.
NUCLEOLI
Ribosomes migrate to the cytoplasm through what? And where is it located?
Nuclear pores, in NUCLEAR MEMBRANE.
Composed of DNA and protein.
CHROMATIN
Scattered throughout the nucleus.
CHROMATIN
Condenses to form chromosomes when the cell divides.
CHROMATIN
Barrier for cell contents.
PLASMA MEMBRANE
Consist of double phospholipid layer.
PLASMA MEMBRANE
The polar head of phospholipid molecule that are “water loving”, attracted to water.
HYDROPHILIC HEADS.
Nonpolar fatty acid “tails,” (water fearing), avoid water and line up in the center (interior) of the membrane.
HYDROPHOBIC TAILS.
