Do plants need photosynthesis to grow a root system? Do plants have pain receptors? How do plants get oxygen for cellular respiration? How does energy metabolism produce heat? How do plant cells maintain homeostasis? Do animal cells have chloroplasts?
Plants produce this protein every day in the late afternoon all year. If there is no light at this time, for example in winter when the sun goes down early, the protein won’t be active. But when spring comes and the days get longer, the FKF1 protein can be made active by day ligh...
secondary metabolites, pathogenesis-related protein expression (e.g. chitinases and glucanases), phytoalexin production, modification in cell wall composition, melatonin production, carotenoids accumulation, and altered activity of polyamines are major induced changes in host plants during pathogen infection...
A region in a tissue where stem cells are maintained, includes cells that produce a short-range stem cell maintenance signal and the surrounding region where the signal is able to maintain stem cell identity. Although plants and animals use different signals to maintain stem cells, the maintenance...
Some people suggest that a country should try to produce all the food for its population and import as little food as possible. To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience. Write at least 250 ...
Interesting facts on plant behavior. They are equipped to adapt to environmental situations and stressors just like humans. They also respond to tactile stimulation, but do plants actually have feelings?
Do plants carry cilia (flagella)?What are flagella and cilia:Flagella and cilia are hairlike structures that extend from the surface of many different types of eukaryotic cells. They are relatively thin and constant diameter (0.2 micrometers) but they vary in length from 2 - 150 micrometers....
Bees feed on the nectar and pollen of flowers. Nectar is a sweet liquid substance that flowers produce specifically to attract bees, birds and other animals. Pollen is a powder that contains the male genetic material of flowering plants. Worker bees (bees whose job is to collect food for the...
For a long time, it seemed that the SC was necessary for Class I crossovers in plants, but studies of plants bearing mutations in transverse filament-encoding genes (ZEP1andZYP1in rice and Arabidopsis, respectively) have shown that this is not the case; in these mutants, the number of Cla...
Plants need to produce flowers to reproduce and, hence, survive. When the flowers bloom, they are pollinated, which results in the mixing up ofgenesfrom other plants of the same species. Eventually, the flowers develop into fruits that contain seeds. The seeds dissociate from the parent plant...
