Answer:
Vultures and Hynas Give only one question for answering
Answer:
here it is
Explanation:
3) the organism is bacteria like fungi
0) true eg- pitcher plant
7) gaurd cells
c1) Nutrition is the science that interprets the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.
2)stomata are the tiny pores present on leaf. they are found in leaves.
#) Carbon dioxide+Water Chlorophyll / sunlight Glucose+Oxygen. 6CO2 + 6H2O = C6H12O6 + 6O2
Saprophytes digest their food externally. They do this by releasing extracellular enzymes which digest the dead organism.
autrophs make their on food, heterotrophs depend on autotrophs. example- autotrophs- plants heterotrophs- humans and animals.
Step 1: A fresh leaf is taken. Step 2: The leaf is boiled in water for few minutes to soften the cells in the leaf. Step 3: Now, dip this leaf in iodine solution. Step 4: The color of the leaf will changes into blue black color when iodine is added to it which shows the presence of starch in it.
Plants can get nitrogen to synthesise protein by- 1) They modify some parts of their body such as apex of leaf and change themselves to become insectivorous plants. 2) Leguminous plants like- pea plants,etc. have rhisobium bacteria in their root nodules which also provide them nitrogen.
