Question

What are the types of cellular arrangement? What is the cellular morphology and cell arrangement of Staphylococcus aureus and Escherichia coli, How are the cyanobacteria different from "regular" bacteria? What is the cellular arrangement of the cyanobacteria and how do they reproduce? What are heterocysts and in which organism are they found? To which group of or paramecium. How do fungi obtain nutrients? Do fungi contain chlorophyll? What are the cell walls of fungi made of? Be able to draw and label/identify parts of the fungus Rhizopus stolonifer. Why are the cells of Elodea green? Where is starch stored in potato cells? 4-15

Explanation / Answer

1)3 basic types of cellular arrangement are cocci bacilli and spiral and based on planes coccus are arranged into diplo strepto tetrad sa tina and staphylo

2)staph aureus ate gram positive cocci arranged in grape like clusters when viewed under microscope has round golden yellow colonies on agar

E. coli are rod shaped bacteria tend to occur individually in large clumps it have single cell arrangement it possesses adhesive fimbriae

3)Cyanobacteria differ from other bacteria as they possess chrolophyll a while others bacteria do not contain chlorophyll

4)cellular arrangement of Cyanobacteria they have wide diversity of shapes most commonly are spherical rod spiral they are unicellular and surrounded by gelatinous sheath

5)Cyanobacteria reproduce asexually by binary fission or multiple fission or fragmentation or spore formation

When favourable conditions they reproduce at explosive growths called blooms

6)Heterocytes are specialised nitrogen fixing cells formed during nitrogen starvation of some Cyanobacteria like nostoc punctiformae

7)paramecium belong to kingdom of Protista

8)Fungi donot contain chlorophyll

Fungi obtain nutrients from non living organic matter that is dead and decaying matter so these are called saprophytes

9)cells walls of fungi made up of chitin,glucans,mannas,glycoproteins

10)cells of elodea green because of chloropasts

11) startch is stored in potatoes in specialised organs calle amyloplasts
