Summary. Like all living organisms, plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found inthe nucleus, the mitochondria and the chloroplasts. The latter two organel
To guar d against this, plants have something like a salety saive(闻). If it coul d re a d to changtog light faster, plants coul d get more sun energy, Niyegi ways.Three protcins control the opening an d closing af those 'salery valves. To increase the levels of these proteins. ...

Define genetic material Are meristems cells diploid? An aster forms during this stage of meiosis. What type of alleles will a pure plant have? How does a strawberry plant reproduce? What was Mendel trying to determine? Where does meiosis occur in flowering plants?
Manipulation of naturally occurring defense mechanisms in host plants is an effective and sustainable approach for plant disease management. Various natural compounds, ranging from cell wall components to metabolic enzymes have been reported to protect plants from infection by pathogens and hence provide ...
Bees benefit flowering plants by helping the plants reproduce, via pollination. Because plants cannot seek out mates the way animals do, they must rely on outside agents, called vectors, to move their genetic material from one plant to another. Such vectors include bees, certain birds and wind...
Do protozoa have flagella or cilia?Answer and Explanation:Some have one, and some have the other. The protozoa are a very diverse group. Here's some more information on them: https://study.com/academy/lesson/what-are-protozoa-definition-characteristics-examples.html...
Male infertility is a complex phenomenon (and also depends on factors such as health, medication use, nutritional status, body fat, and so forth). It can also have a strong genetic component that may include mutations to Y chromosome material. ...
promoter is easy to imagine, while intricate examples of protein retargeting have been identified in plants [59]. We will not comment further on these seemingly surmountable constraints. Experimental transfers in humans and yeast suggest that some constraints are almost insurmountable, however. When ...
What do viruses have in common with cells? How do disease outbreaks occur? How does the immune system respond to bacteria? How does the immune system respond to influenza? How is the rabies virus transmitted? How do viroids cause disease in plants?
