I am a rod-shaped organelle. I produce most of the cell's energy. Who am I?

You are a mitochondria.

1.The estimation of the photosynthetic rate and diffusive conductance of a leaf depends on the accurate measurement of a number of physical properties of the leaf, the air around it, and the light falling on it.\n\n2. Electron transport chains in mitochondria\nThe cells of all eukaryotes (all animals, plants, fungi, algae – in other words, all living things except bacteria and archaea) contain intracellular organelles called mitochondria that produce ATP. Energy sources such as glucose are initially metabolized in the cytoplasm. The products are imported into mitochondria. Mitochondria continue the process of catabolism using metabolic pathways including the Krebs cycle, fatty acid oxidation and amino acid oxidation.\n\nThe end result of these pathways is the production of two energy-rich electron donors, NADH and FADH2. Electrons from these donors are passed through an electron transport chain to oxygen, which is reduced to water. This is a multi-step redox process that occurs on the mitochondrial inner membrane. The enzymes that catalyze these reactions have the remarkable ability to simultaneously create a proton gradient across the membrane, producing a thermodynamically unlikely high-energy state with the potential to do work. Although electron transport occurs with great efficiency, a small percentage of electrons are prematurely leaked to oxygen, resulting in the formation of the toxic free radical, superoxide.\n\nThe similarity between intracellular mitochondria and free-living bacteria is striking. The known structural, functional and DNA similarities between mitochondria and bacteria provide strong evidence that mitochondria evolved from intracellular prokaryotic symbionts that took up residence in primitive eukaryotic cells.

The answer is either b or c.\nI recall that this is the gametophyte generation. I'll go with (b) because I also recall that it was a heart shaped structure.

eukariotic. In fact, eukariotic cells are eukariotic BECAUSE they have nucleus and organelles

Mitochondria:  Power plants\nRibosomes:  Factories (which manufacture things)\nCytoplasm:  hmmm... dunno.  Not citizens, though.

I believe during cytokinesis.

Light IS energy...sorry I can only think of one...:(

the way you have it is good chromozones are part of genes wich are part of cells

Endoplasmic reticulum = 1\nRibosome(s)                 = several\nNucleus                         = 1 but has an inner Nucleolus\nlysosome                      = several\ngolgi bodies                   = I think 1  :)\nmitochondria                 = as u said "mitochondria" & not mitochondrion, so there are several of them\nvacuole                          = several (unlike the plant cell which has one big vacuole)\ncheers

Cytoplasm is the area within the cell inside the plasma membrane (the membrane separate the cell to others) and outside the nucleus (the region contaning genetic materials DNA). Cytoplasm contains many internal organelles (internal structures) that are necessary for cell's functions.\nINternal organelles: Ribosome (needed to make proteins), Golgi complex, lysosomes (digest defective materials in cells, only found in animal cells),Endoplastic Reticulum (2 types: rough with ribosome attached and smooth without ribosome), central vacuole (store H2O, toxins, pigments, waste), Mitochondria (use to make energy for cell, mostly from glucose), chloroplast (needed for photosynthesis in plant cells only),cytoskeleton (connect organelles to each other and membrane, control cell movement, cilia and flagella (cell movements inside an organism).

I is the way to refer to one's self.

eukaryotic\n\neu means true\nkary refers to nucleus\n\nwe have true nuclei in our cells

Mitochondia, because they transform glucose (sugar) to energy.\nChloroplast, because they transform sun energy to glucose.

We all have origins according the context, since I didn't spawn from concrete, I'd say my parents is where I'm from, at least physically... Although I'm pretty sure I've eaten, and replaced all those cells with said food. \n\nSo I guess my body has been shipped from all around the world according to where my diet comes from. I am truly a world citizen. ;)

i think plant and animal cells both have mitochondria. Because mitochondria is the so called powerhouse of the cell, which means the cell derives its energy from the mirochondria. So plant and animal cells should have it to provide them energy.

Almost certainly a plant cell.
