BLAKE BURGETT

• What is a plant?
• A plant is autotroph 1. a living organism of the kind exemplified by trees, and more.
• Plants are multicellular.(eukaryotes)
• Plants have a cell wall around them.
• Plants can vary greatly in size. To moss from trees.

PLANT ADAPTIONS FOR LAND.

• Obtains water and nutrients.
• Retaining water.
• Transporting materials.
• Support.
• And reproduction.

NONVASCULAR PLANTS

• Nonvascular plants are
• low growing plants that live in moist areas.
• There are three types of these plants.
• Liverworts hornworts, and
• Mossees.

MOSSES.

• Mosses are the most diverse plants.
• Mosses are usually found in dark,damp areas.
• Mosses contain rhizoids which obtain water and nutrients.
• Mosses also contain sporophyte,gametophyte,stemlike structure.
• Leaflike structure, capsule and stalk.

LIVERWORTS

• There are more than 8,000 of these species.
• Liverworts are usually found growing as thick crust in rocks in streams.
• The group of plant is named after the shape of the plants gametophyte.
• Which looks like a liver.

HORNWORTS

• There are fewer than 100 kinds of theses species.
• Hornworts are usually found in most soil,often mixed in with grass plants.
• They are named after the slender,curved like structure of sporophyte.

SEEDLESS VASCULAR PLANTS.

• These are seedless plants that have vascular tissue.
• Seedless plants share two characteristics.
• Ferns,club mosses,and horsetails have true vascular tissue.
• Theses plants produce by spores.

FERNS

• There are more than 12,000 species of fern today.
• Ferns have true stems, roots,and leaves.
• The ferns stems are usually found underground.
• Ferns leafs divide into smaller pieces as they grow.
• Ferns leafs are also called fronds.

HORSETAILS.

• There are very few horsetails today.
• The stems of theses plants are jointed.
• The stem also can contain a gritty like substance found in sand.
• Another name for this plant is scouring rushes.

CLUB MOSSES.

• Like ferns, club mosses also have true stems.
• They are only a few hundred species of this plant.
• Unlike other mosses club mosses have vascular tissue.
• This plant usually grows in moist woodland and near streams.

SEED PLANTS.

• Seed plants are plant that contain seeds in them.
• Seed plants share two important characteristics.
• They have vascular tissue and they use pollen and seeds to reproduce.
• Seed plants contain the sporophyte stage and the gametophyte stage.

VASCULAR TISSUE. PHLOEM/XYLEM.

• There are two types of vascular tissue
• Phloem and xylem.
• Phloem is the vascular tissue through which food moves.
• Xylem is the vascular tissue through which water and mineral moves.

POLLEN AND SEEDS.

• Seed plants produce pollen and seeds.
• Pollen is a tiny structure that contains a cell that will later become sperm cell.
• Pollen delivers sperm cells directly near the eggs.
• A seed is a structure that contains a young plant inside a protective covering
• Seeds protect the young plant from drying out.

SEED STRUCTURE

• A seed has three main parts.
• An embryo which is a plant that develops from the zygote to a fertilized egg.
• Stored food which is usually found in the cotyledons or outside the embryo.
• Seed coat which protects the the embryo and it's food from drying out.

SEED DISPERSAL.

• Seed dispersal is the scattering of seeds after forming.
• Seeds are dispersed in many ways.
• One way is using other organism.
• The second way is water.
• The third way is involving wind,

GERMINATION.

• This occurs when the embryo begins to grow again and pushes out the seed.
• Germination begins when the embryo uses it's stored food to begin to grow.
• It also begins when the seed absorbs water.

ROOTS!

• Root anchor a plant in the ground
• They also absorb water and minerals from soil.
• They also store food like this.
• There is two types of root systems.
• 1.) a fibrous root system 2.) a taproot system.

STEMS.

• Stems carry substances between the plants root and leafs.
• The stem provides support for the leaf so they are exposed to the sun.
• Stems can be herbaceous(soft) or woody(hard.)
• There are many layers in stems.
• The most important one is cambium. Cambium divides to produce phloem and xylem.

LEAVES.

• Leaves capture the suns energy to make food.(photosynthesis)
• The layers of leaves contain, phloem,xylem,cuticles,upper and lower leaf cells,and stomata.
• The chlorophyll in the chloroplast which is in the leaf captures the suns energy, then making food.
• The process my which water evaporates from a plant leaf is transportation.
• CO2 enters the leaves through stomata.

GYMNOSPERM

• A gymnosperm is a seed plant that produces naked seeds.
• Many gymnosperms have needle like or scale like leaves.
• They also have deep-growing root systems.
• There are many examples of gymnosperm.

EXAMPLES OF GUYNOSPERMS.

• Cycads which grow in mainly I'm tropical areas.
• Conifers which are the most largest and diverse group of guynosperms.
• Ginkgoes which are mostly extinct but found beside city streets.
• Gnetophytes which can live in desserts or rain forest and also have many varieties of plants.

ANGIOSPERM

• Angiosperms are flowering plants.
• They produce flowers.
• They also produce covered seeds that are in fruits.

EXAMPLES OF ANGIOSPERMS.

• Sunflower.
• tulips.
• marigold.
• lily.
• jasmine.

MONOCOTS VS. DICOTS.

• The two major groups of angiosperm is monocots and dicots.
• Monocots usually have one cotyledon, and Parallel lines.
• They also have bundles of scattered tissue throughout the stem, and flower parts in threes.
• Dicots usually have two cotyledons and branching veins.
• They also have bundles of vascular tissue arranged in the ring,and flower parts in four or five.

TROPISMS:TOUCH,LIGHT,AND GRAVITY.

• A tropism is a plants growth response toward or ways from the stimulus.
• Tough,light,and gravity are three important stimuli to which plants show tropism.
• Touch is like a vine coiling around a wire.
• Light is a plants stem and flowers growing toward a light.
• Gravity is a plants stem growing upward against the pull of gravity.
