Answer:
Chloroplasts are the ’solar energy plants’ of a cell – they convert light energy into chemical energy
This chemical energy may be either ATP (light dependent) or organic compounds (light independent)
Only photosynthetic tissue possess chloroplasts (e.g. is present in leaves but not roots of plants)
Chloroplasts are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis
They have a double membrane structure (due to vesicular coating as part of the endocytotic process)
They have their own DNA (circular and naked) and ribosomes (70S)
Their metabolic processes are susceptible to certain antibiotics
The structure of the chloroplast is adapted to the function it performs:
Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation
Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane
Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption
Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur
Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency

Base on an article I read, the flagellates may be found in the following parts of the human body:
1) <span>reproductive tract,
2) alimentary canal,
3) tissue sites and also the blood stream,
4) lymph vessels and cerebrospinal canal
But, majority of the flagellates are found in the alimentary canal also known as digestive tract. It is composed of the </span><span>mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus, in that order.</span>
Kepler-186f is an exoplanet that orbits around the red dwarf Kepler-186.
Answer: these are secondary metabolites
Explanation:
These secondary metabolites are chemical compounds found in some fungi, bacteria and some plants. They are not involved in true normal growth and other processor in these organisms, but they often help protect plants from herbivory and these include terpenes, alkaloids, phenols etc.
