Answer 1

$\sf\green{ Why\: are \: leaves \: green \: in \: colour ?}$

✓ Leaves have a special green pigment called chlorophyll .

This pigment gives it green colour and also is helpful in photosynthesis.

$\sf\pink{ Why \: is \: sunlight \: so \: important \: for \: a \: plant \: to \: make \: it's \: food }$

✓ Plants make food in the leaves with the process of photosynthesis . Leaves contain chlorophyll ; this chemical makes food using water, minerals , sunlight and carbon dioxide. Hence , sunlight plays an important role in the process of photosynthesis and thus and also the production of food in plants.

$\sf\purple{ Without \: chlorophyll\: food\: cannot \:be\: made \:why?}$

✓Food is preparedthe process of photosynthesis in photosynthesis chlorophyll traps sunlight and thus making chlorophyll important for food production.

$\sf\blue{ Where \: do \: plants \: store \: thier \: extra \: food ?}$

✓ The extra food prepared by the plant is stored in the form of strach. This starch can be found in stems , leaves , fruits and stems.

$\sf\red{ How \:is\: food\: prepared\: by\: plants\: used ?}$

✓ The food produced by plants is stored for the usage in future. This stored food is used for the growth of plant body , repair in case of damage , production of fruits , flowers and seeds.
