How giraffes are born. The average gestation period for giraffes is 15 months. Baby giraffes, known as calves, typically weigh 100 to 150 lbs. (45 to 68 kilograms) and are about 6 feet (1.8 meters) tall when they're born, according to Animal Planet. Giraffes give birth standing up, and the baby falls â head and hooves first â from a height of 6 feet, Holloway said.
The chloroplast allows plants to harvest energy from sunlight to carry on a process known as Photosynthesis. Specialized pigments in the chloroplast (including the common green pigment chlorophyll) absorb sunlight and use this energy to combine carbon dioxide and water and make GLUCOSE and OXYGEN.
â¢ Chloroplasts use light to produce ATP and sugars, whereas mitochondria use sugars to produce ATP. â¢ Chloroplasts found only in photosynthetic eukaryotic organisms, such as plants and green algae, whereas mitochondria found in every eukaryotic organism. â¢ Mitochondria have matrix, and chloroplasts have stroma. â¢ Unlike the mitochondria, chloroplasts contain a pigment called chlorophyll and thylakoid disks.
