Cell Structure Flashcards
Function of ribosome
Site of protein synthesis
Function of cytoplasm
Jelly like material where chemical reaction occur
Function of nucleus
Contain dna which carries genetic information and control cell activities like protien synthesis and cell division
Function of cell membrane
Control movment of substances in and out of cells
Function of mitochondria
Site of aerobic respiration
Synthesis of atp
Function of rough endoplasmic reticulum
Essential component in synthesis and transport of protein
Advantages of stem cell therapy
√used in treatment of type 1 diabetes
√replace cells lost in body
√no rejection if its made from patient’s own cell
√used in treatment of brain disorder like Parkinson’s disease
Disadvantage of using adult/embryonic stem cell
√moral and ethical objections against destroying unused ivf embyros
√long term effects are unknown
√adult stem cells can not differentiate to all type of cells
√stem cell extracted from embyros can be rejected by patient’s bodies as they are not their own cells
Definition of differentiated cell
Is cell changed in shape or structure or both during development to be adapted to carry out particular function
Function of cell wall in plant
It’s made of celluose which is though material that helps plant cell to keep it’s shape
Function of chloroplasts
It is site of photosynthesis and they contain chlorophyll pigments that absorb light energy
Function of Vacuole
Filled with cell sap which is store off dissolved sugurs mineral ions
Levels of organization?
Organelle then cell then tissue then organ then organ system then organism
Definition of organelle
Part of cell with specific function
Cells
Functional unit of living organisms
