Organisms Flashcards
what does MRS C GREN stand for?
Movement, Respiration, Sensitivity, Control, Growth, Reproduction, Excretion, Nutrition.
Movement?
Oranisms move towards things like water and food, and away from things like predators and poisons.
Respiration?
Oranisms release energy from their food by a process called respiration.
Sensitivity?
Found in livings that when any thing which could harm them they get active and sensitive and also response to that.
Control?
Internal conditions include temperature temperature and water content.
Growth?
Must be able to grow and develop into their adult form.
Reproduction?
Organisms have to produce offspring in order for their spies to survive.
Excretion?
Waste products such as carbon dioxide and urine haver to be removed.
Nutrition?
Living organisms need nutrients to provide them with energy and the raw materials for growth and repair. (fats, carbs, vitamins, minerals, proteins…)
What are living organisms made up of?
Cells.
What do cells contain?
Organelles
What are eukaryotic cells?
Complex, and include all animal and plant cells.
What are prokaryotic cells?
Smaller and simpler. (E.g - bateria)
Nucleus?
An organelle which contains the genetic material that controls the cell’s activities. It is surrounded by its own membrane.
Cell membrane?
This membrane forms the outer surface of the cell and controls the substances that go in and out.
