Four adaptation of flowering plants that enable them to carry out cross pollination
Answers
the four adaptation are
1)flower colour
2)fruit colour and size
3)plant size
4)seed colour and shape
Answer:
• Four different adaptations of flowering plants that enable them to carry cross pollination are:
• Uni sexuality of flowers.
• Self sterility.
• Dichogamy.
• Heterostyly.
Explanation:
• Cross pollination is a process in which the stigma receives pollen grains from different plants but belonging to the same species.
• The plants are usually cross pollinated because it allows the recombinantion of new characters, therefore the progeny will be better adapted to the environment and other factors.
• Plants has used several adaptations which allows them to cross pollinate.
• Most of the cross pollinating plants have unisexual flowers, which have either male or female reproductive organs.
• Self sterility of flowers is another mechanism. Even if pollination takes place within the same flower, the pollen grains would not germinate because they are sterile. This enables the pollens from different plants to germinate on the style.
• Dichogamy is a condition in which in a bisexual flower the pollen grains and the stigma does not mature at the same time, which enables pollen grains of different plants to grow on it.
• Heterostyly is a condition in which in a bisexual flower, the anther and the style are placed in different heights which does not enables the plants to self pollinate.
