Question

1. what are the main componets in carbohydrates 2. define chlorophyll and its function 3. why do leaves look green 4. what are stomata and its function 5. in which form do plants absorb nitrogen 6. why leaf is boiled before testing 7.what is the mode of nutrition in plants 8.show with the help of a sketch that the plants are the ultimate source of food ? answer in very short / short then i will mark as brainlist fast plzzzzzz

Answer 1

1. C, H , O
2. ITS A GREEN PIGMENT , HELP IN PHOTOSYNTHESIS
3. SEE ANS 2. due to chlorophyll
4.THEY ARE PORES , HELP IN GASEOUS EXCHANGE / TRANSPIRATION.
5.NITRATES AND NITRITES
6.ITS BOILED IN ALCOHOL AS IT KILLS The LEAF , DISRUPTS THE MEMBRANE and softens the cuticle
7. ITS AUTOTROPHIC
8. SKETCH NP
... REFER TO FOOD CHAIN ...~@lice

Answer 2

1. A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cm(H2O)n .
2. Chlorophyll is a green colour pigment which help in photosynthesis.
Function of chlorophyll :
It helps in making food for plants.
It gives green colour to plants.

3. Leaves look green because of presence of chlorophyll.

4. The tiny opening by which plant breathe is called stomata.
Function of stomata :
It helps in gaseous exchange in plants.

5. Plants absorb nitrogenfrom the soil in the form of nitrate (NO3−) and ammonium (NH4+).

6. In the leaf, excess glucose is rapidly converted to starch, so we test leaves for starch to show that photosynthesis has happened, rather than testingfor glucose. We often indicate that light and chlorophyll are required for the process by adding them to the equation.

7. Hetrotrophic mode of nutrition.
Sorry I don't know the answer of question no. 8
