PLANT CELL COMPOSITION NUR HUDA KHAIRIYAH MDZULKARNAIN189886
-
nucleus : :star:
CONSIST OF
-
-
chromatin
-
-
Chromosomes
-
Chloroplast :star: :
CONSIST OF
-
-
Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency
Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur
Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption
-
Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation
MAIN FUNCTION IS : A site FOR PHOTOSYNTHESIS the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.
Mitochondrial :star:
CONSIST OF
Outer membrane
freely permeable to nutrient molecules,ions, energy molecules like the ATP and ADP molecules
Inner membrane
-
-
permeable only to oxygen, ATP and it also helps in regulating transfer of metabolites across the membrane.
-
Matrix
-
enzymes are important for the synthesis of ATP molecules, mitochondrial ribosomes, tRNAs and mitochondrial DNA
-
Mitochondrial DNA or mtDNA or mDNA is the DNA in the mitochondria, rest of the DNA present in the eukaryotic cells is in the nucleus, in plants DNA is also found in chloroplasts.
-
cell wall
surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
-
-
vacuole
performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water
