PLANTS
Non-Vascular Plants
- Plants that do not have a vascular system (xylem and phloem), ______, roots, or stems. They do not produce ______!
- Examples: ______, liverworts, and hornworts
Non-Vascular Plant Life Processes

1
Synthesis
-Can do photosynthesis (build food molecules)
-Also do ______synthesis and build organic molecules
Transport
-Use diffusion and ______to regulate levels of water, gases, and molecules
Excretion
-Get rid of wastes through ______and osmosis
Respiration
-Take in CO2 and O2 through diffusion [Use CO2 for photosynthesis and O2 for ______]
Nutrition
-Are autotrophic = make their own ______!
Growth
-Start off life as ______, and grow into an adult plant using mitosis
Reproduction
-Reproduce sexually and asexually: The life cycles alternate between haploid and diploid, and they use swimming ______to reproduce
Regulation
-Communicate using hormones, specifically ______, the growth hormone

Vascular Plants
• Produce ______• Have xylem and phloem (vascular tissue)
- Have specialized ______
- Stems: for support and storage (allows plants to grow tall!)
- Contain vascular tissue
- ______: transports water and minerals in the roots, stem, and leaves
- ______: transports dissolved food and nutrients throughout the plant
- Roots: for absorbing water and anchoring the plant
- At the very tip of the roots there is very rapid ______which allows the roots to grow through the soil
- Leaves: for photosynthesis and gas exchange
- Guard cells surround openings, called ______, which regulate the amount of gases and water vapor that enter and leave the cell.
Types of Vascular Plants
-The big differences have to do with reproduction! All can reproduce sexually and asexually, but they do it in different ways.
- Seedless vascular plants
- Examples: Ferns, horsetails, many water plants
- MUST live in water because they have swimming ______that fertilize eggs
- Gymnosperms
- Examples: Evergreen trees, pine trees, gingko trees
- Reproduce with seeds that are exposed “______Seeds” like pine cones, and usually keep their leaves all year long!
- Make male and female cones
- Angiosperms
- Examples: maple trees, vegetables, grasses, flowering plants
- Reproduce with seeds that are covered “______Seeds”
- These plants have fruits that protect the seed and allow it to be dispersed
- HAVE ______!!
- Male reproductive part: ______
- Female reproductive part: ______
- Ovary protects the seeds as they develop, and then ripens as a ______!
- Angiosperms and their pollinators (bees, butterflies, etc.) have ______!
Vascular Plant Life Processes
1
Synthesis
-Can do photosynthesis (build food molecules)
-Also do protein synthesis and build organic molecules
Transport
-Use diffusion and osmosis to regulate levels of water, gases, and molecules
-Use ______and ______to move materials throughout the plant
Excretion
-Get rid of wastes through diffusion & osmosis
-Use ______to get rid of excess water
Respiration
-Take in CO2 and O2 through the stomata via diffusion [Use CO2 for photosynthesis and O2 for respiration]
Nutrition
-Are autotrophic = make their own food!
Growth
-Start off life as ______, and grow into an adult plant using mitosis
Reproduction
-Reproduce sexually and asexually: Most use pollen and eggs to produce seeds. Others can use vegetative propagation (______) to make asexual copies of themselves
Regulation
-Communicate using hormones, specifically auxin, the growth hormone

Day 2 Activity Plants!
Part I: Compare and Contrast: Use the Venn diagram below to compare and contrast Gymnosperms and Angiosperms!
Part II:Using the cladogram below and your knowledge of plants (check your notes) to complete the chart to show how these four groups of plants have changed over time: Write YES or NO in each box!
Type of Plant / Has Vascular Tissue? / Has seeds? / Needs water to reproduce? / Uses cones? / Uses flowers and fruit to enclose the seed?Mosses
Ferns
Gymnosperms
Angiosperms
- Which group of plants is the most primitive? ______
- Which group of plants is the most derived/advanced? ______
- What two tissues make up “vascular tissue?” ______
- Why do you think angiosperms have an advantage over the other types of plants? Explain your reasoning!
1
- What is the purpose of having roots?
- What is the purpose of having stems?
