Answer: Option B. -> creepers
:
B
$\bullet$ Creepers are plants that have weak stems because of which they spread on the ground. Eg: Pumpkin and watermelon.

$\bullet$ Trees are very tall. They have brown, thick and hard stem.
$\bullet$ Plants with green and tender stems are called herbs.

Answer: Option A. -> reticulate   
:
A
The arrangement of veins on the lamina of aleaf is called venation. When this arrangement is net or mesh-like on both sides of the midrib, the venation is called reticulate. If the veins are arranged parallely to each other, then the venation is called parallel venation.

Answer: Option D. -> ovules   
:
D
Ovules are small bead like structures inside the ovary of flower. Ovules contain the female gamete or the egg cell. These structures develop into the seeds after fertilization. Carpel is the female reproductive part of a flower. Stamen is male reproductive part of a flower. Sepals protect the bud of a flower.

Answer: Option A. -> Stigma, style, ovary
:
A
Pistil is the female reproductory part of a plant. Itincludes stigma, style and ovary. Ovules are structures present inside the ovary which contains the female gametes or the egg cells. Pollen grains land on the stigma during pollination. Stigma is connected to the ovary by the style.

Answer: Option A. -> herb  
:
A
$\bullet$ Plants with green and tender stems are calledherbs. They are usually short and they do not have many branches.
$\bullet$ Some plants develop branches near the base of stem. The stem is hard but not very thick. Such plants are called shrubs.
$\bullet$ Some plants are very tall and have hard and thick stem. The stems have branches in the upper part, much above the ground. Such plants are called trees.
$\bullet$ Climbers have weak stem and they take support and climb up.

Answer: Option D. -> Petiole
:
D
$\bullet$ The petiole is the stalk that connects leaf to the stem.
$\bullet$ Lamina is the broad part of the leaf with venation.
$\bullet$ The central vein in lamina is called the midrib.

Answer: Option C. -> trees
:
C
$\bullet$ Trees are tall plants with hard and thick brown stem. The stems have branches much above the ground. Eg: Mango tree.
$\bullet$ Shrubs areplants with branches near the base of stem. The stem is hard but not very thick. Eg: Rose plant.
$\bullet$ Plants with green and tender stems are called herbs. They are usually short and may not have many branches. Eg: Tomato.
$\bullet$ Climbers have very weak stem. They take support and climb up other structures. Eg: Money plant.

Answer: Option D. -> ovule
:
D
Pistil is the innermost part of the flower. It is also the female reproductive part. Stigma, style and ovary are the parts of a pistil. The ovary contains ovule. Ovule contains the female gametes or the egg cells.

Answer: Option A. -> fibrous root
:
A
Fibrous root systems consist of many fine hairlike roots that form a thick mat below the surface. Examples of plants that contain them are grasses, wheat, rice, marigold, maize, banana, millet, bamboo and onions.

Answer: Option D. -> midrib
:
D
Midrib is the thickest vein present in the middle of the leaf. It separates the lamina into two parts in a dicot leaf. Smaller veins are observed radiating out from the midrib.
