5. 5. 3 Distinguish between the following phyla of plants, using simple external recognition features: bryophyta, filicinophyta, coniferophyta, and angiospermophyta 2) Filicinophyta • • plants – have vascular tissue (xylem and phloem) to conduct water and sugars o Have true roots, stems and leaves • Do not produce flowers, pollen or seeds o Reproduce by producing o Sperm eggs and fertilize § Ferns usually grow in places with o Zygote grows into

Ferns frond fiddlehead This is the sporophyte (fern) which produces spores that grow into a gametophyte. This is the gametophyte, called a prothallus, which produces egg and sperm Sperm fertilizes egg to create zygote that grows into the sporophyte (fern)

5. 5. 3 Distinguish between the following phyla of plants, using simple external recognition features: bryophyta, filicinophyta, coniferophyta, and angiospermophyta 3) Coniferophyta • plants that produce • Cone-bearing trees like • Usually with o Evergreen means it retains some leaves all year long • Produce male and female cones o Male cones produce (contains sperm) o Wind often blows pollen to female cone o Eggs are

Conifers Female Male
