Answer: Option A. -> starch
:
A
Plants prepare food by a process calledphotosynthesis. The food synthesised is a carbohydrate called glucose.It is transported to other parts of the plant asstarchfor storage and utilization.

Answer: Option B. -> Climbers
:
B
∙ Plants with weak stems that take support on neighboring structures and climb up over them are called as climbers. Example: Grape vine.
∙ Creepers, like climbers, have a weak stem too but they usually spread on the ground. Example: Pumpkin.

Answer: Option C. -> lamina
:
C
∙Lamina is thebroad part of the leaf. It has veins and veinlets arranged either in a parallel manner or reticulate manner.
∙Important processes like photosynthesis, respiration occur here.

Answer: Option A. -> Tap root
:
A
∙ Tap roots are the root systems found in dicotyledonous plants. They have a main central root that runs deep into the soil. The main root has several lateral roots that are smaller in size. Eg: carrot.
∙ In contrast, fibrous roots have no main central roots. It has a bunch of smaller roots which do not run deep into the soil. Grasses have fibrous roots.

Answer: Option A. -> sunlight
:
A
Sunlight is required for the plants to perform photosynthesis. Plants produce food from carbon dioxide and water only in the presence of sunlight. So, if kept in dark, the plants will not be able to perform photosynthesis and will eventually die.

Answer: Option C. -> Leaf
:
C
∙ The part of the plant shown in the picture is called leaf.
∙ The leaf is the part primarily responsible for making food for the plant. Plants are capable of making their own food through the process known as photosynthesis.

Answer: Option A. -> herbs
:
A
∙ Plants with green and tender stems are called herbs.
∙ Climbers have very weak stem, they take support of nearby structures and climb up.
∙ Creepers, like climbers, have weak stem but they spread on the ground.
∙ Trees are tall and they have hard and thick stem.

Answer: Option C. -> stamen
:
C
In many plants, flowers are referred to asthe reproductive parts. The flowers consists ofmale reproductive structures called stamens and a female reproductive structure called pistil.Stamen consists of two parts-anther and filament. Pistil consists ofthree parts- stigma, style and ovary.
