9Mosses: green fuzzy part you see is the gametophyte Root-like structures called rhizoids anchor the moss & absorb water and nutrients from the soil.Has a long thin stalk with a capsule on the end that contains spores. They live on tree trunks and rocks.
13Hornworts look like liverworts except that they have curved structures growing out of them. They live in moist soil mixed in grasses.
142. SEED PRODUCERS VASCULAR PLANTS Two main divisions of vascular plants:1. SPORE PRODUCERS (ferns, club mosses and horsetails)2. SEED PRODUCERS
15Ferns, club mosses and horsetails need moist surroundings so spores will survive and grow into gametophytes. When the gametophytes produce egg and sperm cells, there must be enough water nearby for fertilization to occur.Most club mosses and horsetails have become extinct …
16All other plants are seed plants All other plants are seed plants. They have two types of vascular tissue (xylem and phloem) and use seeds to reproduce.
17Cells of stems are xylem, or phloem - located in long strands called vascular bundles.
21woodyStems that are hard and stiff. These stems usually don't die back to the ground during the winter. These are stems we use to make furniture and houses.
22herbaceousPlants with stems that are usually soft. These stems die back to the ground every year.
23Two types of seed plants: GYMNOSPERMS:Woody stems(conifers)Produce nakedseeds not enclosed in an ovaryNeedle like leaves
24REPRODUCTION IN GYMNOSPERMS Conifers produce male and female cones - sometimes cones are produced on separate trees
25Male cones produce pollen Females produce one ovule at base of cone
26Pollen falls from male on to female. In time sperm and egg cell join in ovule.Zygote develops into embryo.
27to female reproductive structure POLLINATION: Transfer of male reproductive structureSeed develops & cone size increases.Cones with immature seeds point up & cones with mature seeds point down.to female reproductivestructure
28ANGIOSPERMS: PARTS OF THE FLOWER: Herbaceous stems 2nd type of seed plantANGIOSPERMS:Herbaceous stemsProduce stems in enclosed fruittwo characteristics - produce flowers and fruitPARTS OF THE FLOWER:
29The stigma is the sticky surface at the top of the pistil; it traps and holds the pollen. The style is the tube- like structure that holds up the stigma. The style leads down to the ovary that contains the ovules.
30The stamen has two parts: anthers and filaments The stamen has two parts: anthers and filaments. The anthers carry the pollen. These are generally yellow in color. Anthers are held up by a thread- like part called a filament.
31Petals attract pollinators. The sepals are the green petal- like parts at the base of the flower. Sepals help protect the developing bud.
33Seeds develop once the sperm cells fertilize the egg cells. The seed provides a covering to keep the young plant from drying out.All seeds have an embryo, stored food and a seed coat.
34The young plant that develops from the fertilized egg is called the embryo. The embryo has the beginnings of the roots, stems and leaves.The embryo uses the stored food inside the seed to grow.The stored food is in cotyledons. The outer part is called the seed coat.
35TWO TYPES OF ANGIOSPERMS DICOT: examples are roses, violets and dandelions, oak, maple, vanilla bean and appleFlowers have 4 or 5 petals or multiples of that numberLeaves are wide with veins that branch off each otherStems have bundles of vascular tissue arranged in a circle.
39Life CycleA plant's life cycle describes how long a plant lives or how long it takes to grow, flower, and set seed. Plants can be either an annual, perennial, or biennial.
40AnnualA plant that completes its life cycle in one growing season. It will grow, flower, set seed, and dieExamples: marigolds, tomatoes, and petunias.
41Examples: daisies, chrysanthemums, and roses. PerennialA plant that lives for 3 or more years. It can grow, flower, and set seed for many years.Examples: daisies, chrysanthemums, and roses.(think bushes!)
42BiennialA plant that needs two growing seasons to complete its life cycle. Produces leaves one season, rests in winter and grows flowers & seeds the next season.Examples: parsley, carrots, & foxglove.
43Plant Parts - RootsThe roots provide support - anchor the plant & absorb water and nutrients needed for growth.I’M AROOT!
