Organism c. plants are autotrophs which means they make there own food
A dichotomous key is a 2 choice key. I believe this is the solution.
Stem cells arise from the inner mass of the cell
Signalling factors trigger differentiation in stem cells
Genes that lead to the production of undifferentiated blood cells are activated
Signalling factors cause undifferentiated blood cells to produce red blood cells
Explanation:
Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new red blood cells
Vesicles are used to ship materials around, into, and out of the cell. Cell membranes can pinch off in places to form vesicles, as can lysosome membranes and golgi membranes. Because mitochondria and chloroplasts are practically tiny cells within cells, I wouldn't be surprised if they had their own vesicles. If you're asking literally which organelles have vesicles inside them, I'd say the mitochondria and chloroplasts, possibly Golgi (depends on your instructor), but the cell membrane, lysosomes, and golgi can definitely make vesicles. The rough ER uses vesicles but I wouldn't consider the vesicles a part of the ER.
