What Is An Example Of Green Algae Different From Cyanobacteria?

Pg.284

What are examples of unicellular, filamentous, and colonial green algae?

An example of filamentous green algae is the spirogyra. An example of unicellular green algae is the chlymodomonas and the colonial green algae example is volvox.

How are green algae different from cyanobacteria?

` Cyanobacteria are photosynthetic bacteria while green algae are photosynthetic eukaryotes. Cyanobacteria do not have a nucleus or mitochondria while green algae do. They reproduce asexually while green algae reproduce both asexually and sexually. Green algae are symbiotic with fungi and are a major food source to the marine environment. Cyanobacteria are harmful to some marine species. They both go through photosynthesis differently.

What is meant

Are the stem, holdfast, and blade of brown algae the same as stems, roots, and leaves of land plants? why or why not?

The blade of the brown algae is different from the leaves of the land plants because they lack a stoma, a cuticle and other cells which the plant leaves have. They are however used for the same purpose of photosynthesis although brown algae have an extra pigment which land plants do not contain. The holdfast of the brown algae is for protection from the strong currents of the water while the roots of a land plant are mostly for nutrition purposes. Therefore, although very similar, the brown algae features are different from the land plants

Why, then, do they appear brown or green?

Brown algae contain a different pigment beside chlorophyll called carotenoids pigments. One of those carotenoid pigments, fucoxanthin is a brown pigment that is visible in some brown algae that turn them brown.

7.What are the main differences and similarities among the major groups of algae? How are these groups related to each other evolutionally?

Most algae groups are predominately unicellular while the filamentous algae are multicellular. They all use chlorophyll; however, they use different forms of it. Some algae even have another additional pigment like carotenoid in brown algae. They have different ways of storage but most either use lipids or starch. They are all algae and do not have a covering around their reproductive structures as a form of protections which proves that although polyphyletic, they are related evolutionally.

Describe three ways that algae affect your life?

Algae are found in food and cosmetics. They are used in agriculture since they are found in fertilizers. Algae produces a great majority of the earth oxygen thus making it possible for humans to live.

Why are green algae considered to be ancestral to
