What would we usually do now?...(take notes) and What would we usually start with? (characteristics) I want you to form small groups of 2, 3 or 4 and predict based on your knowledge of previous domains and kingdoms we have studied, what characteristics plants will have in common with each other.

2. Introduction to Plants
Biology II –

3. Characteristics Plants are … Multicellular Eukaryotic Autotrophic by…
True nucleus and complex, membrane bound organelles
Autotrophic by…
Photosynthesis
Autotrophic- any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy.

4. Characteristics (continued)
Cell wall
Composed of cellulose
Cuticle
Waxy covering- prevent water loss
Terrestrial-found on land(some exceptions)
Non-motile
Fixed in one place – don’t move
Seaweed, kelp, algae – not true plants – (protists)

5. Alternation of generations
Two phases of life cycle
Gametophyte – 1n or haploid…
…(1 set of chromosomes)
plant stage that produces sex cells
Sporophyte – 2n or diploid…
…(2 sets of chromosomes)
plant stage that produces spores that grow into organisms (gametophytes)

6. Alternation of generations (cont.)
a haploid gametophyte produces gametes. Gametes unite and give rise to a diploid sporophyte.
Through meiosis, the sporophyte produces haploid spores, which develop into gametophytes.

7. Summary-Plant characteristics
Multicellular
Eukaryotic
Photosynthetic autotrophs
Cell wall – cellulose
Cuticle
Terrestrial
Non-motile
Alternation of generations – (life cycle)

9. Embryophytes
All plants have a stage in their life cycle where they have a protected embryo (early sporophyte)
This distinguishes them from their algal ancestors
The Embryophytes nurture their young embryo sporophyte in the early stages of its development
