Algaes and Protists

Algae are categorized in the following groups:

• 
  
  Autotrophs and heterotrophs.

• Interwoven, filamentous and  phaeophyceae.

• 
  Chlorophyta, chromophyta and rhodophyta.

• omposition, pigments and habitat.

One fact about algae is:

• They carry out photosynthesis and are plant-like organisms.

• 
  They are unicellular microorganisms and animal-like living things.

• 
  They are unicellular or multicellular and heterotrophic organisms.

• 
  They are autotroph and belong to the Plantae kingdom and Protista sub-category.
  

 What characterizes this type of algae?

• 
  They are known as diatoms and can live in various habitats.

• 
  Their cells divide and join in a gelatinous matrix.

• 
  They are the most evolved algae and have structures similar to plants.
  

• 
  They are considered one of the earliest eukaryotic algae.
  

Spherical colonies algae differ from filamentous colonies by:

• Their color and group classification.
  

• 
  Their shape and the gelatinous matrix.

• 
  Their nutrition process.

• The environment where they each develop.

  Vacuoles

  Chloroplasts

• Sporozoans

What is one sub-category of protozoa?

• Protoplasms

• Euglenophyta

• Phagocytosis

• 
  Endoplasm

What is a similarity between sporozoans and rhizopoda?

• They are a source of food for human beings and animals. 
  

• 
  They decompose organisms and provide nutrients in the soil to help plants.

• Both are aquatic and an important source of food for marine animals.
  

• Both are parasitic organisms, harmful for human beings.

Why are protozoa considered animal-like organisms but they don´t belong to the Animalia kingdom?

• 
  Because they can´t move freely and they can´t survive on land.
  

• 
  Because protozoa are unicellular, and animals are multicellular.
  

• Because protozoa are prokaryotic, and animals are eukaryotic.

• Because protozoa are autotrophs, and animals heterotrophs.

What protozoa would be more likely to be found in contaminated water and affect your digestive system?

• 
  Rhizopoda

• Sporozoans

• 
  Protoplasms

• 
  Euglenophyta
