There are very few plants that do not have a helpful side. Dodder, a parasidic plant that grows on other plants and has 100 plus species, is one.
Weeds, defined as any plant that is growing in a place where it is not wanted, are other unhelpful plants; however, they may be helpful if grown in a place where they are wanted.
Some plants have thorns that hurt when you are stabbed with them, some plants cause allergic reactions, and some plants are poisonous to eat and/or touch. Plants are very helpful in life but some really are not.
Protists can be both helpful and harmful. Some protists are beneficial as they play key roles in ecosystems, such as being primary producers in marine environments. However, some protists can also be harmful pathogens that cause diseases in humans, animals, and plants.
These plants are known as algae. They are photosynthetic organisms that can be found in various aquatic environments, such as freshwater and marine habitats. Algae play a crucial role in the ecosystem by producing oxygen and serving as a food source for many aquatic organisms.
Microscopic single-celled simple plants are known as algae. They can exist in different shapes such as spherical, filamentous, or colonial forms. Some algae are harmful, like toxic algal blooms, while others are helpful, providing oxygen and serving as the base of aquatic food chains.
You are referring to algae, which are single-celled organisms that can be harmful or helpful depending on the species. Some algae can produce toxins that are harmful to humans and marine life, while others provide food and oxygen and form the basis of aquatic food chains.
