mention any three differences between circulation in higher plants and higher animals
Answers
Answer:
In Animals heart pumps the blood to all organs/tissues via arteries/arterioles,capillaries etc….heart is the chief component of circulatory system here….blood transports oxygen,nutrients to all tissues….
The blood drains through the veins/venules and returns to the heart,this is ‘CIRCULATORY SYSTEM ‘ happens in animals(humans too)…
Excretion occurs by filtering the blood by kidneys and they exit via urine…same occurs as defecation by digestive system(solid waste)…
Plants does not have circulatory system ,they have “ vascular system “,
two chief components works in the transportation in plants,
water by XYLEM,
food/nutrients by PHLOEM…
here the water and nutrients are transported by CAPILLARY PRESSURE…there is no pumping system available here as animals,root absorbs the water and nutrients….
there is no excretory system available in plants,some of them are stored in vacuoles….
