Photosynthesis

 Photosynthesis

 

Chlorophyll is a green pigment found in almost all plants, algae, and cyanobacteria. Chlorophyll is an extremely important biomolecule, critical in photosynthesis, which allows plants to absorb energy from light. Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion 

What happens inside the chloroplast:

begin with 6CO2+6H2O+light

ends up with C6H12O6+6O2

essentially 6CO2+6H2O+light-----> C6H12O6+6O2

only located in plant cells 

cell organelles

 

1.  Nucleolus- found within the nucleus, it’s a cluster of rRNA and produces ribosomes.   

2. The nucleus- •Stores genetic information, Controls cell division, Directs functioning of cell (provides template for RNA-protein synthesis)

3. Ribosome Site of protein synthesis–polypeptides, enzymes Reads RNA code, translates into amino acid sequence- protein

4. Vesicle-Shipping containers –transport of materials around or out of cell

5. Rough ER-involved in the synthesis of proteins and is also a membrane factory for the cell

6. Golgi Body-Modification of proteins and lipids Storage and packaging of molecules POST OFFICE OF CELL

7. Cytoskeleton-maintains cell shape transport within the cell- movement of vesicles and organelles

8. Smooth ER- Package proteins for transport within cell, Synthesis of membrane phospholipids, Synthesize lipids, triglycerides, steroids, large surface area for chemical reactions, Detoxify drugs in liver cells

9. Mitochondria- production of ATP (site of cellular respiration)

10. Vacuole- vacuoles serve a variety of secretory, excretory, and storage functions

11. Cytoplasm-Cytoplasm offers support to the cell

12. Lysosomes-Are used for garbage disposal and Break down bacteria entering cell, worn out organelles, intracellular digestion

13. Centrioles- Centrioles organize mitotic apparatus which consists of asters and spindle fibers which help in division of chromosomes
