Why is the eardrum important?Eardrum:The eardrum is a thin sheet of connective tissue with epithelial tissue on the outer surface and mucosa on the inner surface. Despite having three layers, the eardrum is so thin that it is semi-transparent....
Florigen (or flowering hormone) is thehypothesized hormone-like molecule responsible for controlling and/or triggering flowering in plants. Florigen is produced in the leaves, and acts in the shoot apical meristem of buds and growing tips. It is known to be graft-transmissible, and even functions...
How does the meristem help plant growth? Why do plants have stomata in the leaves? Why are vascular plants important? Why do larger plants transpire more than smaller plants? Explain. Why is a cactus green? Why are dicots sensitive to the herbicide 2,4-D? Why is a flower's stigma stick...
However, since the meristem confers plant growth and cellular differentiation, it has a high energy demand. Therefore, its mitochondria should not be protected from reactive oxygen species. Also, the hypothesis cannot apply to unicellular organisms. Thus, like most of the genetic model...
Undifferentiated cells in the meristem could not properly specialize into leaves, blooms or stems if cells in the tissue were badly dehydrated. Stems and leaves droop when water needs are unmet, and photosynthesis slows. Plants and Water: Related Science Projects ...
Being the largest organ in the body, the skin is the most important in terms of protecting the internal organs. But what part of the skin helps with patching up scrapes? If it wasn't for this layer of skin and its ability to remain in continuous mitosis, we would still have scrapes fr...
, resistance of leaf to water flow; KNOX, Knotted-like transcription factor; N mass , nitrogen per g of leaf; P mass , phosphorus per g of leaf; R mass , dark respiration rate per g of leaf; SAM, shoot apical meristem; SLA, specific leaf area: UNI, UNIFOLIATA transcription factor ...
Growth is a widely used term in plant science and ecology, but it can have different meanings depending on the context and the spatiotemporal scale of analysis. At the meristem level, growth is associated with the production of cells and initiation of new organs. At the organ or plant scale...
Why is feldspar important? Why is the bicuspid valve important? Why are fold mountains important? Why are amphibians important? Why are air masses important? Why is the stomata important? Why is meristem tissue important? Why is the integumentary system important for the body? How and why might...
Why are chloroplasts important? Why did plants develop vascular tissue? Why do stomata open when guard cells become turgid? Why are epithelial cells seen in urine? Describe cytokinesis in both plant and animal cells. What causes the apical meristem to produce new cells? How do undifferentiated ce...
