Levels of organisation
Simplest level of structural hierarchy and an example
Subatomic level - protons, electrons and neutrons
Define tissue and put an example.
Group of cells that work together to perform a function.
Can you tell the different types of cells?
Prokaryotic and eukaryotic (animal and plant)
First biotic level
Cellular level.
Name two types of connective tissues
Reticular connective, adipose, cartilaginous, osseous, blood.
Which system is made up by the heart and blood vessels?
Circulatory system
What is a organ? Put an example
Groups of tissues with a fonction in common.
Why is a very thin person colder than a thick person?
Because of the adipose tissue. A thin person has less adipose tissue, whose fonction is the heat isolation.
Systems for nutrition
Digestive, respiratory, circulatory and excretory
Name all the levels of organisation from the simplest to the most complex
Subatomic, atomic, molecular, cellular, tissue, organ, system, organism.
Say which tissue is: its cells are elongated and it is responsible for body movement.
Muscular tissue.
Systems for interaction
Nervous, endocrine, muscular and skeletal.
Sat what level of organisation they correspond to: liver, human body, carbon and a protein
Organ, organism, atomic and molecular
Say which tissue is: it form glands, which secrete substances
Glandular epithelial tissue.
Say two differences between the animal and plant eukaryotic cells
Animal tend to have more irregular shapes than plant cells. Vegetal cell has chloroplasts and a big single vacuole.
