Kingdoms Flashcards
What makes an organism a Eukaryote
It has a nucleus
What are all the organelles inside an animal cell
Ribosomes, nucleus, mitochondria, cytoplasm
What are the organelles inside a plant cell
Ribosomes, nucleus, vacuole, chloroplasts, mitochondria
Organelles inside a fungi
Ribosomes, mitochondria
Organelles inside a protoctista
Some have chloroplasts, ribosomes and mitochondria
Organelles in bacteria
Ribosomes, no mitochondria, no chloroplasts
What is a plant cell wall made out of
Cellulose
What is a fungi cell wall made out of
Chitin
Do protoctista have cell walls
Some
Do bacteria have cell walls
Yes
Key features of animals
Unique nervous system, more mobile
Key feature of plants
Multicellular
Key feature of fungi
Multicellular
Key feature of protoctista
Unicellular
Key features of bacteria
Single circular chromosome, no nucleus, have plasmids, very small
Key structural features of viruses
Protein coat, DNA or RNA, some have lipid envelope
Why are viruses acellular
They don’t have a cell membrane, don’t have ribosomes, don’t have cytoplasm
Why are viruses non living
They don’t respire and they use a host cell to reproduce
Examples of viruses
Tobacco mosaic virus= brown spots on leaves
HIV= develops aids in animals
Influenza= gives a fever, cough and diarrhoea
Example of fungi
Yeast, mucor
Examples of protoctista
Amoeba, chlorella, plasmodium
Examples of bacteria
Salmonella, E. coli, lactobacillus
How are fungi’s bodies organised
Mycelium which is produced from thread like structures called hyphae
Function of nucleus
Controls activity of cell
Contains genetic material
Function of cytoplasm
Where chemical reactions occur
Function of cell membrane
Controls what substances leave and enter cell
Function of mitochondria
Carries out some reactions of aerobic respiration which produces ATP
Function of ribosomes
Protein synthesis
Function of a cell wall
Maintains structure of cell
Function of vacuole
Filled with cell sap which contains dissolved sugars, mineral ions and other substances
