6 animal kingdoms
Animal Plants Fungi Bacteria Protoctista Virus
What is multicellular and what organisms from the kingdoms are multicellular
More then one cell
Plants
Animals
Some fungi
Key features of an plant cell
5
Contain chloroplast for photosynthesis Cell walls made of cellulose Carbohydrates stored as starch Some plants store food as sucrose Plants transfer carbohydrates in the form of sucrose
What are the cell walls made of
Cellulose
Carbohydrates stored in plants as
Starch
Some plants save food as what and what it does
Sucrose and plants transfer carbohydrates in form of it
What’s in the plant cell?
Cell wall Cell membrane Chloroplast Cytoplasm Nucleus Vacuole
Key features of an animal cell(6)
No chloroplast, no photosynthesis Gain nutrition by feeding on other animals or plants No cell wall Have nervous coordination They move Carbohydrates stored as glycogen
Differences between animal cell and plant cell
Plants have cell wall, chloroplast and vacuole but animal cell don’t have them
What can fungi not do?
Photosynthesis
Animals store carbohydrates as
Glycogen
Examples of fungi with hyphae, and single called
Mucor, yeast
What is the structure of the hyphae called?
Mycelium
Features of fungi(5)
Hyphae contains many nuclei Some fungi is single cell Fungi have cell walls made of chitin Feed by saprotrophic nutrition Store carbohydrates as glycogen
What does yeast have
Chitin cell wall Cell membrane Nucleus Vacuole Cytoplasm Glycogen granule
What does bacteria have
Slime capsule Cell wall Cell membrane Loop of DNA Plasmids
Bacteria has lack of what
Nucleus but has loop of DNA
Some bacteria do what
