either of the two saclike respiratory organs in the thorax of humans and the higher vertebrates. an analogous organ in certain invertebrates, as arachnids or terrestrial gastropods. at the top of one's lungs, as loudly as possible; with full voice: The baby cried at the top of his lungs.
Mitochondria are the energy factories of the cells. The energy currency for the work that animals must do is the energy-rich molecule adenosine triphosphate (ATP). The ATP is produced in the mitochondria using energy stored in food.Just as the chloroplasts in plants act as sugar factories for the supply of ordered molecules to the plant, the mitochondria in animals and plants act to produce the ordered ATP molecules as the energy supply for the processes of life.ust as the chloroplasts in plants act as sugar factories for the supply of ordered molecules to the plant, the mitochondria in animals and plants act to produce the ordered ATP molecules as the energy supply for the processes of life.
Plants use photosynthesis to create their own food and then use cellular respiration to turn their food into energy (ATP!). Photosynthetic cells are found mainly in the leaves of plants and each cell may have thousands of chloroplasts. QUESTIONS: 1.hloroplast Structure BIG IDEA: Plant cells and some algae contain an organelle called the chloroplast. The chloroplast allows plants to harvest energy from sunlight to carry on a process known as Photosynthesis.
