Tracheid

Vascular tissue

Vascular Tissue

Tracheid, xylem, and Phloem

Antheridium

Produces sperm

Archegonium

Produces eggs

Rhizoid

Similar to roots, no vascular tissue

Angiosperm

Horsetails

Vascular, Seedless

Moss Capsule

Produces spores

Characteristics of Plants

1. Multicellular
2. Eukaryotes
3. Cell walls made of cellulose
4. Greed pigment chlosophyll

Basic Needs of Plants

1. Sunlight
2. Water and minerals
3. Gas exchange for photosynthesis
4. Movement of water and nutrients

Ferns

1. Seedless vascular plants
2. Sporangium is diploid and produces haploid spores
3. Spores develop into gametophytes 1=1

Seed Plants

Gymntosperm- oldest
Angiosperm
Most common
Don't need water for fertilization

Gymnosperm

Cone-bearing (conifers, exposed cycads, seed and ginkgoes, ginetophytes)

Angiosperm

Flowering, fruit

Multicellular green algae

What first plants evolved from

Protonemo

Young gametophyte that forms rhizoids as it grows
