3) Stamen.

4) Carpel or Pistil.

__________________________________

$\textbf{Sepal}$

These are green leaves present at the base of a plant. They protect the flower in bud condition. They contain chlorophyll. So, they also help in pollination.

$\textbf{Petals}$

Answer 2

$\textbf{Parts of a flower }$:

1. $\textbf{Sepals ( Calyx )}$:

Sepals are usually green, leaf like part in the outermost circle of a flower. Main function is to protect the flower in its initial stages of bud.

2. $\textbf{Petals ( Corolla ) }$:

Petals are colourful parts of a flower whose base lies inside the sepals. Main function is to attract insects for pollination.

3. $\textbf{Stamen ( Androecium )}$:

Stamen is the male reproductive organ of the plant. Each stamen consist of a filament, an anther and a connective. Anther is the upper bilobed part and each lobe contains two pollen sacs within which numerous pollengrains are produced.

4. $\textbf{ Pistil ( Carpels ) }$:

Pistil is the female reproductive part of flower, it bearns carpel. It has three parts :

a. Stigma -- Allows pollengrains to stick.

b. Style -- It connects stigma to ovary.

c. Ovary -- It is at the bottom, and contains ovules which have female gametes.
