BIOMOLECULES AND ENZYMES

Detailed explanation-1: -germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.

Detailed explanation-2: -All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth. Some Australian plants need fire or smoke to germinate, while others rely on insects and animals.

Detailed explanation-3: -Unsurprisingly, warm-season crops, like tomatoes, zucchini, and basil, require more heat to germinate than cool-season crops like lettuce, spinach, and radishes.

Detailed explanation-4: -Place some pea seeds on cotton wool in both the beakers. Keep beaker A at room temperature and B in refrigerator. Observation: The seeds in beaker A germinate and in B do not germinate. Result: Suitable temperature is necessary for germination.

Detailed explanation-5: -The embryo inside the seed is made up of a small shoot and a small root. The root is the first to emerge from the seed. As it grows, it anchors the plant to the ground, and begins absorbing water through the root.
