What are the types of material transport mechanisms in a cell?
Active and Passive mechanisms
100
What does ECM stand for?
Extracellular Matrix
100
Are unicellular organisms prokaryotes or eukaryotes?
They can be both, but more often are Prokaryotes
200
When was the cell invented and who invented it?
The cell was invented by Robert Hooke in 1665
200
What is the function of the Smooth ER?
Lipid synthesize and drug detoxification
200
What factors affect passive transport?
Concentration level, Temperature, Molecular size, charge and weight, Solubility in Lipids, Deformation of the Plasma Membrane and Pore number.
200
What does the ECM do?
It plays a role in support, adhesion and movement of the animal cell
200
Mention atleast three unicellular organisms
Amoeba, Paramecium, Euglena, Plasmodium etc.
300
Which kingdoms are made out of Eukaryotic cells?
Protista, Fungi, Plantae and Animalia
300
Which organelle in the cell deals with the packing and secretion of exportable materials?
The Golgi Apparatus
300
What is endocytosis and what types are there?
Endocytosis is the taking of large molecules into the cytoplasm. We have:
Phagocytosis
Pinocytosis
Receptor mediated endocytosis
300
What are Microvilli?
Microvilli are the microscopic projections of plasma membrane which increase the surface area of the cell.
300
What are the levels of organization in multicellular organisms?
Cells, tissue, organs, organ systems and organisms
400
Describe the structure of the cell:
The cell is made up of the Cell Membrane, Cytoplasm and Nucleus
400
Mention at least two types of cells where we can find a Cell Wall?
It is found in plants, protista, fungi and some bacteria
400
What is Osmosis?
The diffusion of water across a semipermeable membrane is called Osmosis.
400
What are the four intercellular junctions?
Desmoses, gap junction, tight junction and plasmodesmata
400
What is the most complex colonial organism?
The most complex colonial organism is the alga Volvox
500
Is cytoskeleton found in Archea?
No, it is only found in Eukaryotic cells.
500
What are Flagella?
Long projections extending from the surface of the cell
500
What is Deplasmolysis?
When a cell is placed in a hypotonic environment, where the water concentration is higher than that of its own cytoplasm, it absorbs water and swells.
500
What is this?
This photo displays material exchange in the form of Plasmodesmata
500
What are the two reproduction types in the amoeba?
Binary fission and Multiple fission
