Title- Protista Lab Concept- the concept of this lab was to explore what is in the pond water as living organisms and try to identify what it is. Some types of Protista are multi-cellular like giant kelp. Although they look much like plants‚ multi-cellular protists lack specialized tissues. Being eukaryotes‚ they have a membrane-bound true nucleus with linear chromosomes‚ and they have membrane-bound organelles. The kingdom Protista contains all eukaryotes that are not plants‚ animals‚ or fungi

traditional farming practices‚ ultimately destroying the communities and fragile land. Natural deserts‚ swamps and salt marshes need to be preserved to protect biodiversity and the integrity of the Earth’s ecology. Introducing genetically engineered organisms into the environment means that these areas could be invaded by these new species therefore furthering loss of natural ecosystems. A major concern of farmers and scientists regarding engineered crops is that they are afraid that these new plants

Ionic bond: A chemical bond resulting from the attraction of oppositely charged ions. Covalent bond: A strong chemical bond in which to atoms share electrons. Cell components (explain their functions): Classification scheme of living organisms: Enzymes (explain functions) : Diffusion: Osmosis: Active Transport: Steps of cellular respiration: How does the body grow and maintain itself? The body is made up of tiny cells - for example‚ skin cells‚ muscle cells‚ heart cells

Environmental Systems and Societies Revision for test week Ecosystems – “An assemblage of parts working together forming a functioning whole.” “A community of independent organisms and the physical environment they inhabit.” All systems have many small parts working together. A system can be living (BIOTIC FACTORS) or non-living (ABIOTIC FACTORS) and has inputs as well as outputs. A system can be an abstract concept as well as something tangible. All systems have: * STORAGES * FLOWS

Etosha: Place of Dry Water Etosha is an ecosystem that contains many interacting species of organisms and their physical environment. As the seasons change‚ the temperature and climate affect the biotic and abiotic factors. Biotic factors are the living organisms that are affected by abiotic factors. Abiotic factors are the non-living or physical factor that directly affects the living organisms. Etosha displays all type of biotic and abiotic factors as the seasons change and the rainy seasons come

biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions of an organism occur within cells‚ and that all cells

True e Energy is recycled within an ecosystem. False 2 Give an example of an organism that is: a a producer in a terrestrial ecosystem Typical producers in a terrestrial ecosystem would be expected to include flowering plants‚ conifers‚ ferns and mosses. b a producer in an aquatic ecosystem In an aquatic ecosystem‚ producers

Homeostasis is the ability of a cell or organism to maintain a stable internal environment despite fluctuating external environmental conditions. An animal will maintain this state of equilibrium through adjustment mechanisms that keep the conditions of its cells and body within a narrow range (SOC 2 n.d.). Homeostasis is crucial to the survival of an organism‚ by maintaining a stable environment‚ it enables cells to be functioning optimally‚ giving an organism the best chance of surviving to a reproductive

identical copies of existing organisms or object. The copied object has the same genetic makeup as the original‚ the copied material is a clone. Scientist have cloned many biological materials such as genes‚ cells‚ tissues‚ and whole organism like dolly the sheep. There is also natural clones‚ some plants and single celled organisms like bacteria make genetically identical off springs through a process called asexual reproduction. In asexual reproduction‚ a new organism is made from a copy of a single
