Question Answer
Main characteristics of protoctists • Mostly unicellular • Heterotrophic or autotrophic • Live in water • Eukaryotic
TWO TYPES OF PROTOCTISTS 1. Protozoa 2. Algae
PROTOZOA
ALGAE
PROTOZOA CHARACTERISTICS -Single cell. -Primary consumers. -Some are parasites. -Reproduce asexually. -Different shapes
Depending on the movement, protozoa are classified in... • Flagellates • Amoeboids • Ciliates
Classification of protozoa • Flagellates • Rhizopods • Ciliates • Sporozoa
3 characteristics of flagellates • Single-celled with flagella. • Live as unicellular or parasites. • Absorb food across membrane.
3 characteristics of rhizopods - No define shape. - Locomotory organs are pseudopods. - No permanent mouth or anus.
2 characteristics of ciliates - Body covered by cilia. - Fixed permanent shape.
2 characteristics of sporozoa - Reproduction by spore formation. - Parasites of animals.
FLAGELLATE
RHIZOPOD
CILIATE
SPOROZOA
Importance of protozoa - Food source for animals. - Oxygen molecules released. - Symbiotic relationships with higher organism. - Biological indicators. - Cause diseases.
Two diseases caused by protozoas - Malaria - African sleeping sickness.
Characteristics of algae - Eukaryotic cells. - Perform photosynthesis. - Autotrophic nutrition. - Producers - Don’t have specialized organs or tissues.
3 types of algae cellular organization - Unicellular - Colonial - Multicellular
UNICELLULAR
COLONIAL
MULTICELLULAR
According to their photosynthetic pigment, algae are divided into… - Red algae - Brown algae - Green algae
Importance of algae - Producers of organic matter. - Produce over 50% of oxygen. - Important in pharmaceutical and food industry. - Used to identify environmental problems.
3 main characteristics of bacteria - Cell organization: unicellular and prokaryotic. - Microscopic - Live in every environment
Types of bacteria - Coccus - Bacillus - Spirillum
COCCUS
BACILLUS
SPIRILLUM
Depending on the way bacteria obtain the organic matter can be classified intro 3 types, which are... - Symbionts - Parasites - Saprophytes
Bacteria reproduction 1. Spore coat 2. Binary fission
