Transport in plants and animals Flashcards
Why do plants need roots?
To absorb water and minerals.
To support the plant in the soil.
To transport water and minerals to the other parts of the plant.
Examples of edible roots :
Carrots
Potato
Radish
Equation for photosynthesis :
CO2 + H2O Light
——————> Glucose + O2
Chlorophyll
What are the ways we use plants for our daily use?
Food
Medicine
Clothing
Tea
Equation for respiration :
C6H12O6 + 6O2 → 6CO2 + 6H2O
Glucose + O2 ———-> Carbon dioxide + water
What is chloroplast?
Green pigment
Osmosis :
Absorbtion of water
Vacuole :
Concentration of water
Biomass :
Renewable organic material that comes from plants and animals.
Structure of arteries :
Large and strong
Structure of capillaries :
Tiny and thin
Structure of veins :
Large and hollow
Function of arteries :
Carries blood away from the heart and into the organs.
Function of capillaries :
Exchange of substance
Function of veins :
Carries blood towards the heart and away from the organs.
Function of red blood vessels :
Carried 02 from the lungs to the other parts of the body.
Function of plasma :
Takes the nutrient to the parts of the body where it needs to be.
Function of white blood cells :
Helps the body fight diseases.
Function of platelets :
To stop bleeding.
What is the respiratory system
Organs that help to get O2 from the air into our blood and get rid of CO2 make the respiratory system.
Colour of oxygenated blood :
Bright red
Colour of de - oxygenated blood :
Blackish red
Define oxygenated blood :
A blood cell that has a high amount of O2 and a low amount of CO2.
Define de - oxygenated blood :
A blood cell that has a high amount of CO2 and a low amount of O2.
