BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Plants can respond to the change of season by losing their leaves, flowering, or breaking dormancy. Plants go through seasonal changes after detecting differences in day length.

Detailed explanation-2: -Plants respond to their environment in a variety of ways. The response of an organism, usually a plant, to an environmental stimulus is called a tropism. Some common plant stimuli include light, gravity, water, movement of the sun, and touch. The naming of the tropism is associated with the stimulus.

Detailed explanation-3: -In spring, flowers bloom. In summer, fruits ripen. In autumn, leaves change colour and fall. In winter, plants rest.

Detailed explanation-4: -During spring, many seeds germinate, buds open, and many animals have their young. Summer is a time when plants and young animals grow and become strong. In fall, leaves fall from trees, crops are harvested, and animals prepare for winter. Some animals hibernate during winter, and some plants are dormant.

Detailed explanation-5: -Short-day plants control their flowering by blooming when days are short. Long-day plants bloom when the nights are short and the days are long, usually in late spring and summer. During this time of year, the nights are short and the days last longer than 12 hours.
