Term | Definition |
---|---|
Unicellular Organisms | A unicellular organism is an organism made up of only made up of one cell. Normally they are smaller than a speck of dust because there is only one cell in the organism. You can’t see them with the naked eye. They can live pretty much anywhere soil. |
Why are Unicellular Organisms so Small? | Unicellular organisms are usually micro-sized because cellular activities are performed most freely at that size.The control is related to the processes of diffusion and osmosis. The processes that gives gases and water to cells and gets rid of waste. |
In Mr GREEN What cells are what. M=? R=? etc. | Movement - Muscle cells Reproduction - Sperm and egg cells Growth - Bone marrow stem cells Response - Brain/ nerve cells Exchange of Gases - Alveolar macrophage cell Excretion - Liver/ bladder cells Nutrition - Intestines/ stomach cells |
What are some Advantages of Specialized Cells? | Having specialized cells mean your cells have the potential to become much more confused. They can lead to having complex issues/organs/organ systems. The class of tasks because you’re breaking up and dividing the work up within the organism. |
What are some Disadvantages of Specialized Cells? | A lot of energy is invested in the work of cells such as bacteria, archaea. Some protists don't have specialized cells so they can devote a lot more energy to survival and reproduction cells. |
Some ways of dehydration are... | Increased thirst, Dry mouth and swollen tongue, Weakness, Dizziness, Palpitations, Confusion, Sluggishness, Fainting, Headache. |
How do amoeba eat? | The amoeba stretches out it’s pseudopod and surrounds the food, to pull into the rest of it’s body. Engulf is the amoeba surrounds the food using it’s ability to change shape and then the food turns into a temporary vacuole. |
What do amoeba eat? | They mainly eat algae, bacteria, plant cells, microscopic protozoa and metazoa. |
Where they live? | It seems that amoeba mainly only live in lakes, streams, rivers, fresh water, salt water, etc. some are only found in morning dew well others are found in parasitic and live in the bodies of other organisms. |
Multicellular organisms | A multicellular organism is an organism made up of more than one cell so it can be seen by the naked eye because there are more then one cell in it. |
How amoeba exchange gases and handle water conditions? | The water will come into the organisms through osmosis. Osmosis basically the diffusion of water. The amoeba takes in the water and the oxygen that the organisms need is diffused into the cell. |
