The Cell (PPT based) Flashcards
each cell is a discrete entity bound by a membrane that “isolates” it from it environment
Cell
What are the 3 components of the body?
- Cell
- Intercellular or extracellular substances
- Body fluids
materials that lie between cells to support and nourish them
Intercellular or extracellular substances
Body fluids includes:
- Blood
- Tissue or intercellular fluid
- Lymph
Body fluids:
confined within the vascular system
Blood
Body fluids:
between and around cells
tissue or intercellular fluid
Body fluids:
drain tissue fluid back to the venous system
lymph
The science concerned with the minute structure of cells, tissues and organs in relation to their function.
Histology: Microanatomy
the smallest unit of protoplasm capable of living independently. It is the structural and functional unit of the body.
The cell
2 types of cells:
found in primitive cells such as bacteria
PROKARYOTIC
2 types of cells:
in all higher plants and animals
EUKARYOTIC
2 types of cells:
metabolic and hereditary components are mixed
PROKARYOTIC
2 types of cells:
bulk or hereditary material is isolated in a membrane-bound nucleus lying in the remainder of the cell or cytoplasm
EUKARYOTIC
2 types of cells:
have no histones (specific basic proteins) bound to their DNA
PROKARYOTIC
2 types of cells:
no membranous organelles
PROKARYOTIC
What are the components of protoplasm?
- Protein
- Nucleic acids
- Carbohydrates
- Lipid
- Inorganic Materials
- Water
COMPONENTS OF PROTOPLASM:
main structural elements of the cell and the intercellular material
PROTEIN
COMPONENTS OF PROTOPLASM:
exist as: pure lipoprotein, glycoprotein, proteoglycan, or mucoprotein
PROTEIN
NUCLEIC ACIDS:
found mainly in the nucleus
DNA
NUCLEIC ACIDS:
nucleus and cytoplasm
RNA
