Plant Types/ Parts and Functions Plants: Grouped by characteristics Vascular Three main parts: roots, stems and leaves Roots can be different sizes: Fibrous and tap roots Storage roots; beets, carrots, sweet potatoes and turnips Roots have different functions: anchoring the plant, taking in
water and minerals, and store food. Nonvascular Simple; most grow in moist places No vascular tissues. Two Types of Plants Angiosperms are fruit or flower bearing.
Gymnosperms are naked seeds and cone bearing. Angiosperms Two Groups: Monocots and Dicots

Roots 2 Types of Root Systems Taproot Fibrous System Image found at: http://www.puc.edu Roots
Taproot System Primary roots grow down from the stem with some secondary roots forming Image found at: http://www.arboretum.fullerton.edu Roots Fibrous Root
System Small lateral roots that spread out just below the soil surface Image found at: www.wildmanstevebrill.com Can you identify these root types?
Root Functions Roots have 4 primary functions Absorption of water and nutrients performed by root hairs Transportation of water and nutrients to stem Anchor plant to maintain stability
Store food and water Parts of the Root Epidermis Outermost layer of cells, like the skin of the root Cortex Tissue inside epidermis that stores starch and other substances for the growth of
the root Parts of the Root Root Cap Provides protection for the root tip Root Hairs Site of absorption

Important Functions of Leaves Photosynthesis Process that plants use to produce their food 6CO2 + 6H2O C6H12O6 + 6O2 Transpiration Loss of water and exchange of carbon
dioxide Leaf Parts Blade Main body of leaf Petiole Attaches blade to stem
Midrib Large central vein Image found at: www.yourdictionary.com Leaf Parts Apex Tip of leaf Base
Attaches to petiole if petiole is absent, attaches directly to stem Margin Edge of leaf Epidermis Skin of leaf - responsible for gas exchange Stomata
Outside layer of leaf opening in epidermis where gas and water exchange Mesophyll Middle layer of leaf where photosynthesis occurs Functions of the Stem Transport water and nutrients
from roots to leaves Supports leaves, fruit, and flowers Food storage Image found at: www.karencarr.com Parts of the Stem
Node Areas where side branches and leaves develop Internode Area between nodes Xylem Carries nutrients up
Phloem Carries nutrients down Pith Stores food Image found at: www.ext.colostate.edu Flower Function
Sexual Reproduction!!!! Flowers are pollinated by: Wind Insects Birds Flower Parts Pistil
Female part of plant Containing: Stigma Style Ovary Image found at: www.howe.k12.ok.us Flower Parts Stamen
Male reproductive part Contains Anther Filament Image found at: www.botanyworld.com Flower Parts
Petals Highly colored part of the flower, may contain perfume and/or nectar glands Sepals Small green structures on the
base of a flower that protect the flower bud Image found at: http://biology.clc.uc.edu Parts of the Seed Embryo Growing part of seed containing: Plumule Shoot
Hypocotyl Stem Radical Root Endosperm Tissue that provides nutrition for the developing seed Cotyledon Food Storage Seed Coat Protective outer covering of the seed
Parts of the Seed Image found at: www.puc.edu Pollination Flowering plants use the wind, insects, bats, birds and mammals to
transfer pollen from the male (stamen) part of the flower to the female (stigma) part of the flower. Pollination A flower is pollinated when a
pollen grain lands on its stigma. Each carpel grows into a fruit which contains the seeds. Fertilisation Pollen grains germinate on the
stigma, growing down the style to reach an ovule. Fertilised ovules develop into seeds. The carpel enlarges to form the flesh of the fruit and to protect the ovary.
Wind pollination Some flowers, such as grasses, do not have brightly coloured petals and nectar to attract insects. They do have stamens and carpels. These flowers are pollinated by the
wind. Seed dispersal Seeds are dispersed in many different ways: Wind Explosion Water Animals
Birds Scatter How birds and animals help seed dispersal Some seeds are hidden in the ground as a winter store. Some fruits have
hooks on them and cling to fur or clothes. How birds and animals help seed dispersal Birds and animals eat the fruits and excrete the seeds away from the
parent plant. Physical Adaptations Allowing Plants to Survive on Land Cuticle waxy covering of leaf for water loss protection Spores and Seeds reproductive cell protection Tissue for absorbing and transporting materials
Spines and needles making ingestion difficult. Storing water in stem as a cactus does. Cuticle Waxy coating preventing water loss Seeds Embryo surrounded by a protective coating
Moss (Spores) Haploid reproductive cell surrounded by a hard outer wall Foxglove plant produces a chemical affecting the heart Poison Ivy
Chemical Adaptations Allowing Plants to Survive Chemicals that are toxic and can kill organisms eating them Foul odor Bitter taste Toxicity
An organism that gets its energy by eating, or consuming, other organisms Consumers are heterotrophs because they feed on other organisms to get their energy There are different types based on what it consumes
General grounds maintenance to include cleanup of overgrown vegetation, grass cutting, weed eating, hedge trimming, leaf raking and mulch placement. Ongoing Parish Hall window restoration. Troubleshot and repair of various plumbing and electrical system failures, as well as repair furniture
