respiration system
equation for aerobic respiration
oxygen + glucose --> carbon dioxide + water + large amount of energy
what parts of a cell differentiates animal and plant cell
plant cell has chloroplast and cell wall while animal cell does not
list the components of blood
red blood cells, white blood cells, platelets and plasma
equation for anaerobic respiration
glucose --> lactic acid + small amount of energy
what does chloroplast do
contains chlorophyll to absorb sunlight for photosynthesis
why do red blood cells have no nucleus
allows the rbc to carry more haemoglobin and transport oxygen more effieciently
what does the cilia in trachea do
sweep and remove mucus
function of ribosomes
translates genetic information from mRNA and synthesises proteins
state the functions of the 2 main kinds of white blood cell
lymphocytes : produce antibodies to remove toxins and harmful microorganisms(pathogens)
phagocytes: carry out phagocytosis which breaks down and remove foreign bodies and microorganisms by engulfing them
what is mitochondria
the powerhouse of the cell that releases energy during aerobic respiration
sort the blood vessels from thickest to thinnest layer
arteries, veins, capillaries
function of xylem and phloem
xylem transports water and mineral salts from roots to leaves for photosynthesis,it also acts as a mechanical support for the plant
phloem transports food(sucrose and amino acids) from leaves to other plant parts
