Ovule develops from cushiony part of ovary called placenta. Ovule is connected to placenta by a stalk known as Funicle. The tissue enclosed inside the ovule is Nucellus. It is surrounded by two covering or Integuments, the outer and the inner.
The two integuments leave small pore known as Micropyle. Basal part of ovule where the two integuments arise is known as Chalaza.Let`s draw the ovule, the basic shape of ovule is like tilted egg. Here we go.
1.Draw a tilted egg shape with a oblique line showing the axis.
2.Erase the bottom and draw the outer integument and then inner integument
as shown.
3.Draw another oval shape to represent embryo sac within.
4. Draw the seven cells in embryo sac as shown and label the parts.
