Answer:
2 true......................
T - Leaves hold the plants upright.
T - Potatoes, grown in cooler climates or seasons around the world, are often thought of as roots because they usually grow in the ground. But technically they are starchy, enlarged modified stems called tubers, which grow on short branches called stolons from the lower parts of potato plants.
T - The root system is fibrous and consists of two types of roots namely, 'selt roots' and 'shoot roots'. When sugarcane selt is planted in the soil and covered with moist soil, the root primordial (translucent dots) situated at the base of every cane joint is activated and produces roots.
T - Internode is the leafless portion of stem.
F - It is not possible to carryout photosynthesis without carbon dioxide because during photosynthesis food is produced by the reaction between sunlight, carbon dioxide and water.
