What does Xylem tube do?
carries water and minerals from the roots to the stem
What does Phloem tube do?
carries dissolved sugars from the leaves to other parts of the plant
Word equation for Photosynthesis
carbon dioxide + water—-> glucose + oxygen
To test a leaf for starch (step 1)
Boil a beaker of water, put leaf in beaker for 2 min
To test a leaf for starch (step 2)
Remove leaf from water, place in boiling tube with ethanol inside
To test a leaf for starch (step 3)
place boiling tube in beaker of hot water and wait until ethanol turned green
To test a leaf for starch (step 4)
remove leaf and wash it, place inwhite tile and add droplets of iodine
To test a leaf for starch (step 5)
if the leaf turned blue/ black, starch is present
What is stomata
small openings in the surface of the leaf that allows gas to diffuse in the leaf
why do plants need minerals
minerals are needed for plants to stay healthy
Give 4 examples of adaptations plants made
- Stomata for gas exchange
- Xylem to transport water to leaf
- Phloem to transport nutrients to leaf
- Air spaces for gas exchange
What is the energy used for from respiration
> movement
growth and repair of cells
control of body temperature
what is aerobic respiration
aerobic respiration is respiration involving the use of oxygen
word equation for aerobic respiration
glucose + oxygen—–> carbon dioxide + water(+energy)
where does aerobic respiration take place?
in the mitochondria
when does anaerobic respiration occur?
Anaerobic respiration occurs in the absence of oxygen , usually happens during exercise
word equation for anaerobic respiration
glucose—> lactic acid(+energy)
which respiration releases more energy?
aerobic respiration
what is fermentation?
fermentation is a type of anaerobic respiration carried out by plant cells and organism like yeast
