Well the process of life involves something called photosynthesis which is the exchange of oxygen for CO2. We breathe in oxygen and let out moist CO2 which plants use to grow and make their food called sugar, which is another whole cycle.
Depends on the plants. Trees takes in the CO2 and changes it to Oxygen. To much CO2 in the air can harm plants and overwork them and even kill them.
it plays a role in a movie and inyou peeing
It is playing a roll on every animal. it is the way make food.
The cuticle is a useful adaptation in plants but not in algae because: in order for plants to live on land, they need a cuticle to prevent water loss during dry climates. Algae live in the water, therefore they don't need a cuticle to survive. They use their adaptations to absorb the water and nutrients around their watery environments. Source: My straight "A" brain
Plants play a huge huge role. They create oxygen which forms ozone.
it gives energy to the algae and many other animals eat the algae.
Algae is a vital food source for marine organisms from plankton to the tadpoles of frogs. Seaweed is also an algae and not only is grazed by fish but is a valuable fertilsier for use in farming. Algae may also be responsible for kick starting the generation of oxygen in the atmosphere of the early Earth. Photosynthesis is a clever trick that algae and plants have developed to turn sunlight, carbon dioxide and water into sugars and oxygen. We owe our life to this process since it gives us food and air to breathe.
It provides life-giving oxygen for people and animals and provides carbon dioxide for plants.

It provides a home for a special kind of algae
What role does the weather play in an Englishman's life
A tree can play the role of a habitat and/or feed.
Protista is algea and many water plants/bacteria. Protists are a big part of the nitrogen process in marine life.
