Wildflowers are plants that grow on the forest floor. during a study, a scientist observed that wildflowers began to bloom before the leaves appeared on the tall trees above them and stopped blooming once the trees were full of broad leaves which blocked the sunlight. evaluate this observation and explain a limiting factor this is affecting the wildflowers on the forest floor.

This adaptation limits the amount of the the flower has to grow and reproduce. It uses the time where the trees do not have leaves and therefore do not block the sunlight  to grow and reproduce. But when the trees began to grow leaves and use the sunlight for themselves, the wildflower stops blooming and goes into a sort of hibernation mode, storing all the food in the storage organelles in its cells.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
