1 Kingdom Plantae Biology 11

2 Kingdom Plantae Multi-cellular Autotrophic Eukaryotic
Cell walls made of cellulose Store food in the form of starch

3 Have chloroplasts containing chlorophyll
Most are terrestrial, some are aquatic


5 Prepare a table to compare Nonvascular and Vascular
Vessels (xylem and phloem) Leaves, roots, stems Examples

6 Nonvascular No vessels No roots No stems No leaves
Ex: Mosses and liverworts

7 Vascular Have vessels to transport food and water
They have roots, stems and leaves Ex: grass, corn, trees, flowers, bushes

8 Xylem: transports water
Phloem: transports food & nutrients




12 Vascular Plants can be sub-divided into Seedless vs Seed Plants

13 Seedless plants (e.g., ferns) have a vascular system but reproduce using spores.



16 Seed Plants can be further subdivided into Gymnosperms and Angiosperms
Type of protection for seed Type of leaves Growing season Type of pollination Examples

17 Seed Plants Gymnosperms Cone-bearing plants
“naked seeds” = seeds that are not enclosed. needle-like leaves usually stay green year round wind pollinated Examples: pine trees & other evergreens


19 Seed Plants Angiosperms Flowering plants
Seeds are enclosed, usually in a fruit Have finite growing seasons Most are pollinated by birds & bees The most successful group of plants Examples: grasses, tulips, oaks Divided into two main groups: Monocots & Dicots


21 Angiosperms can be further subdivided into Monocots and Dicots
Number of Cotyledons Type of leaf veins Type of root Arrangement of vessels Examples

22 Monocots 1 seed leaf (cotyledon) parallel veins on leaves
3 part symmetry for flowers fibrous roots Vascular tissue scattered Example: lilies, onions, corn, grasses, wheat


24 Dicots 2 seed leaves (cotyledons) net veins on leaves
flowers have 4-5 parts taproots Vascular tissue arranged in a ring Examples: trees and ornamental flowers



27 Success of Angiosperms
Transport gametes over great distances. Efficient dispersal via fruit. Tough, water resistant leaves for survival in hostile environments.

28 Pollination Co-evolution between flowers and pollinators.
Birds are attracted to red flowers. Bees can see colors that humans cannot. Moth-pollinated flowers are white and bloom at night.

29 Many insects are attracted to odors
Many insects are attracted to odors. One species smells like rotting meat and is pollinated by flies. Flowers are often shaped so that non-pollinators cannot reach nectar or pollen. For example, hummingbird-pollinated flowers are long, and shaped like the bill of a hummingbird. Wind-pollinated flowers are small, have no petals and little color and do not produce nectar.


31 Problems living in a terrestrial ecosystem
Support - in water, the plant is held up. On land, a support system is required.

32 Getting Water and Nutrients
Aquatic plants are surrounded by water and nutrients so most cells can just absorb them the environment. Terrestrial plants require a system for collecting and transporting water. Plants developed root systems that can collect and transport water. Some plants have shallow roots which spread out to collect water. Water carrying minerals from the roots can travel to all parts of the plant and food made in the leaves can travel to non-photosynthetic parts of the plant.

33 Drying Out Leaves are covered by a waterproof outer layer called the cuticle. Openings in the leaves called stomata allow passage of gases for photosynthesis but can be closed when it is too warm. Gymnosperms have very narrow leaves to minimize water loss.

34 Spreading Gametes Spores – tiny reproductive cells are carried long distance by the wind Seeds: The embryo inside the seed is surrounded by a tough, drought-resistant, protective seed coat. Food packaged in the seed provides energy for the young plant until it can grow above the soil and begin photosynthesizing. Adaptations of seeds help in their dispersal. Some seeds are carried by wind, stick to the fur of animals or are eaten.


36 Today’s Work Complete the Monocot/Dicot colouring with the large lily on the back YOU SHOULD BE VERY FAMILIAR WITH THIS COLOURING FOR THE UNIT TEST!
