Textbook Question
Chapter 45, Problem 2FIB
In a flowering plant, the male gametophyte is the __________. It is formed in the __________ of a flower. Pollination occurs when pollen lands on the __________ of a flower of the same plant species. The pollen grain grows a tube through the __________ of the carpel to the ovary at the base of the carpel. The tube enters an ovule through an opening in the __________ of the ovule.

After pollination and fertilization, as the ovule develops into a seed, the ovary matures into a _________________. Many of these have three parts. The _________________ is the skin or peel. The ________________________ is the flesh, and the innermost layer, the ____________________, may be tough like the pit of a cherry.
Below are photos of an conifer immature ovulate cones (I.s.) at
and 40x.
Make a sketch of the 10x slide and label the following structures: ovuliferous scale, sterile bract,
micropyle, megasporangium, megaspore mother celli (Note: do you see the pollen grain situated in the
micropyle of a scale?)
Pine pollen grains have air bladders (wings) whereas flowering plant pollen grains do
not. The reason for this is;
Flowering plant pollen grains are not multicellular like pine pollen grains
Pines are wind pollinated
The wings on pine pollen grains are needed to form the pollen tube
The wings on pine pollen grains are needed to form the sperm nucleus
