To practice drawing and improving your pencil stroke, it is always interesting to take inspiration from the things around us. So make a banana appear on a sheet of paper by drawing a few curves and do not forget the small details that will make it more real than life.
Steps

Step 1. Draw a curve
On a sheet of paper, draw a curve that goes up on each side. This curve should look like a smile.

Step 2. Make a circle
In the middle of the curve, draw a circle with the curve going through its center. This circle should have a diameter that represents the size of your banana.

Step 3. Draw a second curve
Make a second curve of the same shape as the first. It should follow the bottom of the circumference of the circle and its ends should join those of the first curve. This new curve will therefore be the lower limit of your banana.

Step 4. Sketch a new curve
This third curve should land on the upper part of the circumference of the circle. As for the previous curve, the ends will join those of the other two curves. This curve represents the upper limit of the banana.

Step 5. Add two curves
Between the middle curve and the top curve, draw a curve in the middle, the ends of which will join the other ends of the other curves. Do the same between the middle curve and the bottom curve. You now have a banana which is made up of six curves.

Step 6. Make the rod
At one end of the banana, trace the stem. Make a small rectangle, part of which should be partly on top of the banana tip.

Step 7. Finalize the end of the rod
Draw a bubble whose diameter is the width of the rectangle. The bubble should stretch upwards to end in a point. This will make the stem appear more realistic and will look like it has been ripped from a bunch of bananas.

Step 8. Trace the tip of the banana
At the other end of the banana, make a small circle to finalize the shape of the end of the banana.

Step 9. Remove unnecessary strokes
Now that the banana is drawn, erase the circle in its center as well as all the other superfluous lines to keep only the final lines of the banana.

Step 10. Color the banana
Add a final touch to your design by coloring the ends and the rest of the banana brown with a gradient of yellow and green. You are done with your drawing once you are done coloring it.
