Module 2: Organisation of Cells
1Q2: What is the difference in nutrient and gas requirements between autotrophs and heterotrophs?
Autotrophs
Produce their own nutrients
Plants
Photosynthesis
Require both oxygen and carbon dioxide
Nutrients are taken from the water as it contains water soluble nutrients
Heterotrophs
Consume other beings to obtain nutrients
Animals
Respiratory System
Oxygen in taken in, Carbon Dioxide is removed as a waste product
Digestive system
Obtains nutrients from the food eaten as it absorbed slowly throughout the whole digestive process
The Intestines absorb the majority of the nutrients
Carnivore, Omnivore and Herbivore
IQ3: How does the composition of the transport medium change as it moves around an organism?
Mammals
Circulatory system
Blood
Plasma (55%)
Red Blood Cells (41%)
White Blood Cells (Part of 4%)
Platelets (Part of 4%)
Heart
2 Chambers (Left and Right)
Deoxygenated Blood passes through the right atrium and right ventricle
It then passes onto the pulmonary artery to become oxygenated and leaves the lungs through the pulmonary vein
From here, oxygenated blood is sent through the left atrium and left ventricle and lastly through the aorta where it is pumped around the body.
Blood Vessels
Arteries
Arterioles
Thicker than veins
Veins
Venules
Capillaries
Lymphatic system
Cleans Blood
Comprises of Lymph and lymph nodes
Plants
Vascular Tissue
Xylem
Transports Water and water soluble nutrients
Is made of dead cells fortified by lignin
From the roots up the leaves
Transpiration-Cohesion-Adhesion Theory
Continuous tube
Phloem
Transports sugars
Translocation theory
Is made of living cells that form valve like structures
IQ1: How are cells arranged in a multicellular organism?
Cell Structure and how it relates to function
Cell Specialisation
Animal cells
Plant Cells
Stem Cells
Embryonic and Adult
Ability to differentiate
Unicellular
One cell
Multicellular
Multiple cells, different
Colonial
Same type of cell grouped together
Eukaryotes and Prokaryotes
Order or arrangement
Cells
Tissue
Organs
Organ systems
Organism
Organelles
