|
Phylogeny
|
-tries to explain how groups of animals are
related in an evolutionary context |
|
|
Taxonomy
|
is the classification of living
organisms based on similar: • Structural characteristics • Molecular (genetic) characteristics • Developmental characteristics |
|
|
What is unique in
the Amoeba? |
Free-Living
Pseudopodia (vs axon/dendrites) Contractile vacuole Food vacuoles |
|
|
All cells must:
|
1. take up nutrients.
2. regulate amount of water in cell 3. get rid of waste material 4. reproduce/grow |
|
|
Amoeba Eats?
|
Phagocytosis:The food particle is captured by
the pseudopodia and is taken into the cell by forming a food vacuole in the cytoplasm. |
|
|
Transport Vesicles
|
The transport vesicles take the digestive enzymes
to the Golgi apparatus where they are processed and packaged into lysosomes. |
|
|
Amoeba Digestion?
|
The lysosomes containing the digestive enzymes
fuse with the food vacuole. The food is digested in the food vacuole by the enzymes. |
|
|
Unicellular Organism
|
A single celled organism that can survive and reproduce as a single cell.
|
|
|
Pseudopodia
|
Thin, fingerlike projections from edges of cell, filled with cytoplasm.
|
|
|
Amoeba movement?
|
Pseudopodia
|
|
|
Kingdom Protista?
|
Paramecium, Amoeba
|
|
|
Amoeba Phylum?
|
Sarcomastigophora
|
|
|
Paramecium Phylum?
|
Ciliophora
|
|
|
Paramecium Eats?
|
Ingestion: food swept into oral groove
by cilia and directed to cytostome .Formation of food vacuoles at a specific site at end of cytostome - by means of PHAGOCYTOSIS (or endocytosis). |
|
|
Paramecium Digests?
|
Digestion of food in food vacuoles.
Ci l i f f d l di ib Lysosome Circulation of food vacuoles to distribute Paramecia nutrients to rest of cell.Egestion: the release of undigested food by fusion of vacuole membrane with plasma membrane (called exocytosis) at anal pore = cytopyge. |
|
|
Does Paramecium reproduce sexually or asexually?
|
Both
|
|
|
Protista Characteristics?
|
Unicellular.
Contains organelles. |
|
|
Sporozoans Characteristics?
|
Lack locomotion, organelles, parasitic.
|
|
|
Sporozoans Phylum?
|
Apicomplexia
|
|
|
Groups of Protista?
|
Amoeba, Parameciums, Sporozoans.
