Set a\xa0lotus plant\'s\xa0rhizomes in the container\'s clay soil, with the rhizomes\' shoots facing upward. Rhizomes are similar to bulbs.\xa0In early and mid-October, their leaves turn yellow and wither, and the\xa0plant\xa0enters dormancy. The entire growth period\xa0is\xa0160 to 190 days and needs an accumulated temperature of about 4,000 degrees Celsius. That\xa0is\xa0the ecological reason why\xa0lotus flowers can\xa0flourish everywhere. | |

What is five kindome |
| Answer» There are five main kingdoms. They are:\tKingdom Monera: These organisms are prokaryotic and unicellular. They do not have a well-defined nucleus and also lack cell organelles.\tKingdom Protista: Organisms grouped under Kingdom Protista are all unicellular, but eukaryotic organisms. These are the simplest forms of eukaryotes that exhibit either autotrophic or heterotrophic mode of nutrition.\tKingdom Fungi: Heterotrophic, Multicellular and Eukaryotic organisms are grouped under Kingdom Fungi. Their mode of nutrition is saprophytic as they use decaying organic matter as food.\tKingdom Animalia : This Kingdom includes organisms that are Multicellular, Eukaryotic, without the presence of cell wall. They have a heterotrophic mode of nutrition. They also exhibit great diversity. Some organisms are simple while others have a complex body with specialized tissue differentiation and body organs.\tKingdom Plantae: These are Eukaryotic, Multicellular organisms with a cell wall that is made up of cellulose. They are autotrophs and synthesize their own food through the process of photosynthesis. This kingdom includes all plants. | |

Function of pineal glands |
|
Answer» Secretion of melatonin : This gland secretes the hormone melatonin which regulates the circadian rhythm of the body and also certain reproductive hormones. The secretion of this hormone depends upon the amount of light a person is exposed to. This hormone is produced in large amounts when it is dark. The presence of light inhibits the secretion of melatonin which controls our circadian rhythms.Cardiovascular Health : The melaton in secretion has a positive impact on the heart and blood pressure. It may also be used for the treatment of cardiovascular diseases.Reproduction : Melatonin inhibits the secretion of reproductive hormones from the anterior pituitary, which are responsible for the development and functioning of reproductive organs. Have you read chp-13 Scientists haven\'t searched about this but it regulates some hormones ,including melatonin |

Can you tell me something about bulliform cells in terms of flaccid and turged |
| Answer» Bulliform cells\xa0are the\xa0cell\xa0that is spread among the leaf\'s epidermal\xa0cells. They are essential for water storage. During stress circumstances,\xa0bulliform cells\xa0assist to roll leaves to avoid water loss through transpiration. Therefore, they control the process of transpiration.\xa0Bulliform cells\xa0or the motor\xa0cells\xa0are the modified epidermal\xa0cells\xa0present on the upper surface or the adaxial surface of the monocot leaf (the grasses). They regulate the rolling of leaves to prevent the loss of water. When water is adequately present, they become\xa0turgid\xa0and keep the leaf open and exposed. | |
