photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very similar to higher plants. Algae are voluntarily and involuntarily kept

required in plant growth. Nitrogen and phosphorous were tested separately‚ where the concentration of each was increased while the other remained constant. The results showed a positive increase in algal growth rate in the phosphorous samples and a negative relationship with increased nitrogen levels. In this way‚ phosphorous acted as the more significant nutrient in algal growth and should be controlled to prevent eutrophication. I. Introduction Several nutrients are required for plants to grow

What is Soil? Soil is the surface of the earth’s crust where plants have their roots and where many small animals make their home. It is also a result of the breakdown of rocks. Formation of Soil Soil is formed when rocks break down into very small particles by various processes such as weathering. There are two types of weathering: Physical Weathering and Chemical Weathering. Physical Weathering arises from the heating and cooling‚ the wetting and drying‚ and the freezing and

Dear Coach Williams‚ i’m writing to you from the Amazon Rain Forest. It’s currently raining and a little humid‚ but the animals don’t seem to mind. There are thousands of species of Animals‚ as well as plants‚ in the Amazon. It does rain a lot and there aren’t really changes in seasons. The soil isn’t the greatest in the Amazon. There are surprisingly many different tribes Here. There are many things to talk about after being here in the Amazon. There are a variety of animals in rainforests

laboratory reading for the experiment stated that lichens are instrumental in the development and needs for all species. The text stated‚ “Lichens play a part in the creation of soils from which plants can obtain nutrients. Like all living organisms‚ lichens need nutrients and energy to grow. Nutrients may be obtained from the air including dust‚ water‚ and from the substrate organisms grows on obtaining energy through photosynthesis‚ which is the role of the algal partner. They may also be incidentally

Basic Ecological Concept Levels of Organization Cells- are composed of Cell Membrane‚ Nucleus and Protoplasm. Tissue-is an aggregation of cells performing a common function or functions. Organs- is the aggregation of tissues usually forming a definite shapes‚ and performing a definite function within an organ system. Organ System-is a group of organs that perform coordinated functions together to keep the organism alive and functioning well. The scope of the biology includes the study of all

decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples of possible things to add to the decomposition chamber are leaves and compost. Lastly‚ the terrestrial chamber contains a small plant or seed as well as soil and/or fertilizer or mulch. The purpose of our making the eco-columns

Germination is the process by which a plant grows from a seed. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. However the growth of a sporeling from a spore‚ for example the growth of hyphae from fungal spores‚ is also germination. In a more general sense‚ germination can be simply anything expanding into greater being from a small existence or germ‚ a method that is commonly used by many seed germination projects. Seed germination

Compare and Contrasting Plants and Animals Man has come a long way from the caveman days and so has our understanding of the world around us. Humans have always used plants and animals in one capacity or another‚ yet when a person thinks of the phrase ’plants and animals’‚ they automatically begin thinking about the differences between the two. Well I say that plants and animals have been known far too long for their differences. And as different as they seem‚ plants and animals are very similar

If you were of the opinion that cultivated plants and domesticated animals is what wildlife consists of‚ you are mistaken. Wildlife‚ in fact‚ comprises of the innumerous varieties of wild plants‚ animals‚ fungi and microorganisms that exist on our planet earth‚ rather than just cultivated plants and domesticated animals. Knowingly or unknowingly‚ we largely depend on this wildlife for every elementary requirement in our life. The food we eat‚ the clothes we wear‚ the medicines we consume‚ a variety
