Identify the type of carpel with the help of diagrams given below :
$(a)$ In ovary many pistils get together/accumulate and forms a combined/united structure which is called syncarpous ovary. e.g. (Poppy).
$(b)$ More carpels in united state in ovary and connected with parts of ovary, is called apocarpus. e.g. mitcheli.
Indicate the stages where meiosis and mitosis occur $(1,\, 2$ or $3)$ in the flow chart.Megaspore mother cell $\xrightarrow{1}$ Megaspores $\xrightarrow{2}$ Embryo sac $\xrightarrow{3}$ Egg
Ovules are borne on
What does the filiform apparatus do at the entrance into ovule?
In angiosperms, the following events occur during megasporogenesis and megagametogenesis
$(i)$ Differentiation of megaspore mother cells
$(ii)$ Meiosis of the megaspore mother cell
$(iii)$ Formation of a linear tetrad
$(iv)$ Mitotic division of the functional megaspore
$(v)$ Degeneration of 3 megaspores
$(vi)$ Formation of embryo sac
$(vii)$ Fusion of polar nuclei
The correct sequence is
