Cell Flashcards
(42 cards)
Basic building block of life
cell
Smallest living unit of an organism
cell
Capable of growth, reproduction, energy
adaptation, and response to the environment
cell
Two types of Cells
Prokaryotic Cell
Eukaryotic Cell
The earliest and most primitive forms of life on earth
Prokaryotic Cells
Have more complex structures and intracellular processes
Eukaryotic Cells
Specialized subunits within a eukaryotic cell and Has its own specific function
Organelles
Usually separately enclosed within its own membrane
Organelles
ORGANELLES: Suspended in thick intracellular fluid called the
CYTOSOL
Major Functions:
• Synthesis and degradation of biomolecules
• Selective transport of biochemical substances
• Metabolism
• Storage, transmission, and expression of genetic information
Organelles
Lysosomes and Flagella
ANIMAL CELLS
- Chloroplasts (Plastids)
• Central Vacuole and Tonoplast
• Cell Wall
• Plasmodesmata
PLANT CELLS
Contains the genetic material of the cell and Site of DNA and RNA synthesis
Nucleus
Site of protein synthesis
Ribosome
Network of membrane channels connected to the nuclear pore
Endoplasmic Reticulum
Contains enzymes for detoxification of foreign
substances that gained entry into the cell
Endoplasmic Reticulum
contains the ribosomes
Rough ER
site of lipid synthesis
Smooth ER
Sorts and transports molecules for export into
the plasma membrane or other cells
Golgi Complex
Contain hydrolytic digestive enzymes aimed
for intracellular digestion
Lysosomes
Contain oxidative enzymes for intracellular digestion
Peroxisomes
Site for Cellular Respiration
Mitochondrion
Cellulosic inert supporting structure surrounding
plant cells for rigidity
Cell Wall
Site of photosynthesis and Contains chlorophyll,
the pigment responsible for harvesting light
Chloroplast
