Bacteria, virus, protists

Protists

Most diverse group of eukaryotic organisms.

Plant-like protists

Algae, precursors to land plants.

Animal-like protists

Protozoans, precursors to animals.

Fungi

Eukaryotic, heterotrophic organisms with chitin cell walls.

Example of fungi

mushrooms, yeast, mold

Vascular plants

Plants with specialized tissues for water transport.

Gymnosperms

Seed plants with exposed seeds, like conifers.

Angiosperms

Seed plants with flowers and covered seeds.

Cellulose

Sugar polymer forming plant cell walls.

Chitin

Structural polysaccharide in fungal cell walls.

What is bacteria?

a prokaryotic

Capsule

helps in attachement, layer on the outside of the cell wall, most but not all have it

Pili

attachment, hair like, allows cells to stick and transfer DNA

Flaglleum

long whip like strunce, helps move cell around, motility

Cell wall

protection, within the capsule

Ribsomes

protein synthesis

What is the most diverse kingdom?

Kingdom protista

What does protista include?

protozoan and algae

Protozoan

early animal

who gave rise to the invertebrate animals?

Protozoans

What did algae give raise to?

plants

All protists are what?

eukaryotic

Some protists are unicellular, are all?

no, some are multicellular

Protozoan are classified by what?

locomotion

Algae

• plant like

• photosyntheic

• NO motility

• eukaryotic

Protozoans

• animal-like

• most are NON-photosyntheic

• motility

• eukaryotic

Flagellum

whip like tail

cilia

small hairs

pseudopods

false feet

Kingdom fungi are all what

eukarytioc

yeast is an example of what

a unicellular part of the kingdom fungi

What are fungi

they are heterotrophs

Barticea are

prokaryote

What do fungi have?

cell walls made of chitin

Gymosperms

naked seeds, not covered by a fruit

Angiosperms

seeds covered with fruit, flowering plants

What makes up viruses?

there are 2 main parts, made up of nucleic acid and protein

Virology

study of virsues

Do viruses cause disease?

yes, many

Viruses depend on what?

the living, but they are considered nonliving

How do virues reprouced in host cells?

with the lytic cycle

Stages of the lytic cycle

1. Attachment

2. penetration

3. replication

4. assembly/maturation

5. lysis

Attachment

of virus to host

penetration

of virus into host

replaiction

of virus DNA

assembly/maturation

of new viruses

lysis

release of new viruses
