Please help me with ALL of these questions. Thank you so much

Question 7 0.3 pts The chloroplast is a membrane-bound organelle very similar to the mitochondrion. Both organelles are thought to have been acquired through an endosymbiotic event where a bacterium was engulfed by an ancestral eukaryotic cell and accidentally retained over evolutionary time and evolved into specialized organelles. Which area of the chloroplast is most similar to the inner membrane of the mitochondria such that both areas in these two organelles contain the Electron Transport Chains? inner membrane of chloroplast outer membrane of chloroplast thylakoid membrane intermembrane space stroma Question 8 0.3 pts In mitochondria, the inner membranes of chloroplasts are highly convoluted so as to greatly increase surface area and permit many complexes of the Electron Transport Chain. Which membrane is similar inside the chloroplast and has a high surface area which allows for many complexes of Photosystems and Electron Transport Chains? intermembrane space stroma thylakoid membrane outer membrane of chloroplast inner membrane of chloroplast

Answer 1

Ans- 7 thylakoid membrane

Ans-8 thylakoid membrane

Explaination of 7 and 8- thylakoid membrane are the sites in the thylakoid where light dependent reactions of photosynthesis occurs. The thylakoid membrane of chloroplast is similar to the inner mitochondrial membrane and consists of many complexes for electron transport chain as well as two types of Photosystems. This ETC helps in movement of electrons from PS-II to PS-I . Chloroplast have extensive thylakoid membrane to carry out the essential functions.

Ans-10 carbon dioxide and sunlight

Photosynthesis is the pathway used to synthesis carbohydrates like glucose snd further cellulose with help of carbon-dioxide and sunlight.

All other components are produced during photosynthesis like oxygen, cellulose and some are formed from the complex carbohydrates which are synthesized by photosynthesis.

Ans- 11- more

a photon of blue light have more energy than photon of red light because red light has higher wavelength than the blue light and energy is indirectly proportional to wavelength. This means that higher than wavelength, lesser will be the energy and lower the wavelength, higher will be the energy. Formula of energy=  

E = hc

Ans-12 green

The plants donot absorb green light wavelength and reflects it back. This is the reason why plants are seen green in colour as chlorophyll cannot absorb the light effectively.
