hat are Plants and How did they Evolve: Plants are multicellular‚ photosynthetic organisms‚ adapted primarily for life on land. With a combination of both‚ underground and aboveground structures‚ plants have the ability to absorb water and mineral nutrients from soil while food production is also occurring through the process of photosynthesis. Scientists assume that plants where the cause of evolution‚ adapting from aquatic green algae 500 million years ago. Many essential adaptations would have

INSECTIVOROUS PLANTS An insectivorous plant‚ also called a carnivorous plant‚ captures prey items‚ such as insects‚ spiders‚ crustaceans‚ mites‚ and protozoans‚ as a nitrogen source. Many insectivorous species live in freshwater bogs‚ where nitrogen is not present in available form‚ because the pH of the water is extremely acid. The forms of entrapment by these types of plants are modified leaves. Five basic trapping mechanisms are found in carnivorous plants. 1. Pitfall traps (pitcher plants) trap prey

Lauren Kelly Individual Student Presentation 28 July 2013 Toxic Plants 10. Would you believe that there’s a tree so poisonous that you don’t actually have to touch it to be harmed? It’s called the manchineel tree (found throughout the Florida Everglades‚ Central America and the Caribbean. Inhaling sawdust or smoke tree may result in a variety of uncomfortable side effects‚ including coughing‚ laryngitis and bronchitis. Some reports suggest that simply standing beneath the tree during a rainstorm

DNA- is the material found in the nucleus that contains the genetic info. 4 billion codes in length Gene- a segment of DNA that controls a certain protein production. A gene is made up of hundreds to thousands of codes. Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like‚ body function‚ body communications‚ and enzyme control) DNA screening- the process of testing individuals to determine

Limit the uptake of other nutrient‚ which is magnesium or potassium. Older leaves at the bottom of plant will start to become yellowish (chlorosis) while the rest of the plant’s leaves will be light green.

Anatomy of flowering plants deals with the study of internal structure of various organs of flowering plants. The tyloses are the structures present in the woody tissues of dicot stems. These are the extension of xylem parenchyma cells into the vessel elements(NEET-II 2016). Cortex tissue is present in between the epidermis and stele. It is multilayered and is made up of parenchymatous cells with big intercellular spaces (NEET-II 2016). Wood of gymnosperms does not contain vessels.e.g- Pinus is

Stem cell research has the potential to affect the lives of millions of Americans. In my research you will understand; the history of stem cell research‚ International stem cell control list‚ and the legislation. Hopefully‚ after reading this you will be able to form a strong opinion on stem cell research. What is stem cell research? According to Stem cell information‚ “An adult cell is thought to be an undifferentiated cell( cell that is not developed) which is found among developed cells in

Embryonic vs. Adult Stem Cells - Why Jean Swenson Doesn’t Support Embryonic Research and Why An Audience Would Listen As science becomes more and more advanced‚ there are many more ways to combat illnesses. Some of these are more successful and widely known‚ but one of the more controversial is stem cell research. In the article "Embryonic Stem Cell Fairy Tales"‚ Jean Swenson attempts to educate the public on why she believes many are prone to believing that embryonic stem cells (which have not
