Q

Why are viruses not placed in one of the kingdoms

A

That’s because viruses display some non-living and living characteristics

A

A parasite organism that can not complete its life cycle without exploiting a suitable host(if a obligate parasite can not obtain a host it will fail to reproduce).

Q

Flagellum|Flagella

A

A whip like protuding filaments that help cells or microorganisms move

17
Q

Autotrophic

A

Animals which can synthesize their own food

18
Q

Heterotrophic

A

Any organism that sources food from its environment because it cannot make its own food.

19
Q

Saprophytic

A

Plant or fungal microorganisms that feeds on dead or decaying tissues of other organisms.

20
Q

Binary fission

A

Asexual Reproduction of a single cell in which divides by mitosis.

21
Q

Plasmid

A

Is a small circular ,double stranded DNA molecule that is distinct from a cells chromosomal DNA

22
Q

Two types of autotrophic bacteria that can manufacture their own food

A

●Photosynthetic bacteria (which use sunlight energy )

●chemosynthetic bacteria (which get their energy from chemical processes)

23
Q

Three types of heterotrophic bacteria that can not manufacture their own food

A

●Parasitic bacteria - (That obtain their foods from other living organisms)

●Saprotrophic - DECOMPOSERS(they obtain their food from dead animals and plants)

●mutualistic bacteria- (That form a relationship with another organism.Both organisms benefit from the relationship.

24
Q

Aquatic

A

Living in or around water

25
Q

Phytoplankton

A

Very small plants (algae)that float on or near the surface of the water.

26
Q

Zooplankton

A

Consisting of small animals and the immature stages of larger animals which float on or near the surface if the water

27
Q

Sessile

A

Organisms that are usually attached to something and can not move on their own but can move through outside sources.

28
Q

3 types of protists

A

1.PLANT LIKE PROTISTS
●mainly unicellular organisms found in aquatic environments
●most are autotrophic
●free floating aquatic called phytoplankton.

2.ANIMAL LIKE PROTIST
●heterotrophic
●free living unicellular animals living in an aquatic area

3.ALGAE
●multicellular
●microscopic called seaweeds
●contains various Photosynthetic pigment which give them a green ,red or brownish color.
●may be free floating or sessil.

29
Q

Chitin

A

A fibrous substance consisting of polysaccharides, which is a major constituent in the exoskeleton of arthropods and the cell walls of fungi

30
Q

Hyphae

A

A network of multi called thread like filaments forming the mycelium of a fungus

31
Q

Mycelium

A

A vegetative mass or network of fungi hyphae found in and on soil or organic substances

32
Q

Multi nucleate

A

Cells that have more than one nucleus per cell

33
Q

Rhizoids

A

Threadlike structures that anchor lower plants and fungi to a surface

34
Q

Budding

A

A form-fitting asexual Reproduction which involves the pinching off of offspring from the parent cell the offering cell is genetically identical to the cell
