Q

Why would we bother to identify plants to family?

A

Very useful plant ID tool, much easier to identify plants if we know the family. Members of the same family tend to share morphological patterns and share similar characteristics

Q

What are the morphological traits of the flowers of the Asteraceae? Are they a good way to identify a member of the family?

A

Each inflorescence can have thousands of tiny flowers. Ray flowers will be on the edge, and their 5 petals are fused into a large ligule to attract pollinators. Disk flowers will be in the middle and have their 5 petals partially fused so that they form a tube. Each flower has 5 petals and 5 fused stamens. Sepals have been modified into a pappus. Very good way to identify

Q

How do the Asteraceae maximize their time to get pollinated and reduce the chance of self-pollination?

A

The flowers mature at different times, with the ray flowers maturing first and then the disk flowers mature from the outside in. Male parts mature before the female parts to reduce the chance of self-pollination

Q

What are the morphological traits of the flowers of the Poaceae? Are they a good way to identify a member of the family?

A

Grass flowers are called spikelets. Petals and sepals are very reduced since they are wind-pollinated. Anthers stick out to catch the wind and the stigmas are feather-like to catch pollen. Good identifier
