Characteristics of living Organisms

Question 1

Characteristics of the Living Organisms

Answer 1

Movement, Respiration, Sensitivity, Control, Growth, Reproduction, Excretion, Nutrition (MRS C GREN)

Question 2

What happens if something does not carry out all of these life processes?

Answer 2

Then they would be either dead or non-living (e.g. Viruses)

Question 3

Movement

Answer 3

Is an action by an organism causing a change of position or place. The movement of an organism from one place to another is called locomotion

Question 4

Respiration

Answer 4

Is a chemical reaction carried out in all living organisms. Energy is released from glucose either in the presence of oxygen (aerobic respiration) or in the absence of oxygen (anaerobic respiration). This reaction results in the production of carbon dioxide and water as waste products

Question 5

Sensitivity

Answer 5

Is the ability to detect and respond to stimuli in its surroundings

Question 6

Control

Answer 6

Living organisms must control their internal environment in order to keep conditions within its required limits. This is called homeostatsis

Question 7

Growth

Answer 7

Is the permanent increase in size

Question 8

Reproduction

Answer 8

Is the process that leads to the production of more of the same kind of organism. There are different types of reproduction: sexual (the male and female gametes fuse together) and asexual (cell or whole organism that can reproduce)

Question 9

Excretion

Answer 9

Chemical reactions that take place inside living cells are described as metabolic reactions. Metabolic reactions produce waste products, some of which can be toxic

Question 10

Nutrition

Answer 10

All organisms must obtain food to provide energy. Plants use sunlight, carbon dioxide, and water to produce oxygen and glucose in the process of photosynthesis. Animals consume other living organisms in order to obtain the energy they require
