ABSTRACT The exercise was about the techniques in proper sectioning of plant tissues and staining techniques so that the study of plant structure will be easier. In free hand sectioning‚ the plant organ must be 45° upright and is held between the thumb and the base of the forefinger. A razor blade was used to cut the plant thinly in cross sections. Obliquely cut tissue is a big mistake since the surface of the tissue will not be even upon viewing under the microscope. Iodine-Potassium-Iodide

eusocial insects. Termites mostly feed on dead plant material‚ generally in the form of wood‚ leaf litter‚ soil‚ or animal dung‚ and about 10% of the estimated 4‚000 species (about 2‚600 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings‚ crops or plantation forests. Termites are major detritivores‚ particularly in the subtropical and tropical regions‚ and their recycling of wood and other plant matter is of considerable ecological importance

High School Department General Science How Does Phosphate Affect the Growth of Aquatic Plants? (A Problem Proposal) I. Introduction Aquatic plants are an important component of lake systems. These plants may be totally submerged beneath the lake surface‚ floating‚ or growing along the shoreline. They provide food and shelter for bugs‚ fish and other organisms‚ prevent shoreline erosion‚ filter pollutants from adjacent shoreline activities‚ and

remained in the soil‚ a sapping sprouted out of the stone. That was many years ago. An old man saw the newly sprouted sapping. He knew that it was the one of a mango of good quality. He took it to a garden and cultivated it there. There it grew into a plant and then into a big tree as I am today. My leaves are green and thick. They protect those who sit under me from the rays of the sun. Peacocks love me in particular and dance around or near me during the rainy season. It is not only for shade that

Annona cherimoya is one of the species of Annona genera belonging to the angiosperm Annonaceae family. The family is shared by sugar apple (Annona squamosa) and soursop (Annona muricata). It is an ancient family of plants believed to have originated from frost free valleys of Andean American area specifically southern Ecuador and northern Peru (Julian et al.‚ 2013). According to Pinto et al. (2005)‚ many of its species are still in their initial stages of domestication and are considered to be in

sweeter food sources rather than the salty ones. On the other hand‚ two sets of modular organisms were subjected to environmental changes‚ a set for the sun-loving plants (Cyperus and Althernanthera) and shade-tolerant plants (Zebrina and Talinum) were interchangeably exposed to each other’s environment. Results generally showed that when plants are put into an environment where they are not used to‚ they tend to grow poorly and vice versa. But some developed mechanisms to lessen the impact of the stress

Plants can reproduce both sexually & asexually. When producing offspring sexually‚ plants cannot simply grow legs to find a mate nor can they maneuver their sex cells to a different plant all by themselves in order to reproduce. So how do they do it? Well there are multiple ways that this process occurs. All of which differentiate who or what helps the plant spread its seeds. Plants spread their seeds through wind‚ water‚ & animals. A perfect example of how wind disperses seeds of plants

growth of each plant. Pods 1‚ 3‚ and 4 never broke through the soil‚ and remained at a depressing 0 centimeters the entire length of the experiment. The 2nd pod did grow slightly. It took 14 days for the plant to show any type of growth‚ measured at .3 centimeters. Unfortunately‚ that little value never increased. The substrate is very heavy‚ and most likely slowed the process of breaking through the soil. It has a spongy-like water

with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do not grow around others? This phenomenon can
