Plants are classified as either vascular or nonvascular 1) vascular plants have a collection of “pipelines” that bring water and minerals up from roots, disperse sugars down from leaves

-vascular tissue allows plants to grow higher off the ground Ex: trees, sunflowers

2) Nonvascular Plants -have no special “pipelines” -they grow close to the ground or on tree trunks to absorb water/nutrients directly -EX: mosses, liverworts

Roots: store and absorb nutrients; anchor and support the plant Overview of Plant Structure and Function Roots: store and absorb nutrients; anchor and support the plant

Just above the root tip are tiny projections called “root hairs” Shoulder Partner Just above the root tip are tiny projections called “root hairs” 1) What do you think is the Function of “root hairs”? 2) What does this function have to do with “surface area”?

Stems: transport nutrients between leaves and roots Contains the vascular tissue system

Should Partner Plants are made up of different tissues. Predict what the function of these tissues are based on the picture below…

Vascular Tissue System: Transport system  Xylem: tissue that transports water and dissolved minerals  Phloem: tissue that transports sugars

Ground Tissue: tissue system that makes up most of the plant, structure and storage

Dermal Tissue System: forms the outer covering of plants  Epidermis: outer layer of cells covered by a waxy cuticle

Shoulder Partner Dermis tissues can be compared to what organ on a human?

Shoulder Partner Ground tissue can be compared to what organ on a human?

Shoulder Partner Vascular tissue can be compared to what organ on a human?

STAP - stop-think-and-predict 1) What function does this structure serve in plants?

Leaves: primary site of photosynthesis Stomata: leaf structures (pores) that regulate the passage of gases (carbon dioxide and oxygen) into and out of the plant Guard Cells: surround the stoma/stomata to allow water and gases to move in & out.

Which of the following is the correct reactants for photosynthesis? 1234 Review Which of the following is the correct reactants for photosynthesis? Carbon Dioxide and Oxygen Glucose and Oxygen Carbon Dioxide and Water Glucose and Water

Plant Tissues Meristem Tissue– at the end of the roots where new root growth occurs Cambium – the layer between the bark and the core

Plant Processes Photosynthesis Cellular Respiration Transpiration Reproduction

Energy Photosynthesis Cellular Respiration 6 CO2 + 6H2O  C6H12O6 + 6O2 Cellular Respiration C6H12O6 + 6O2  6 CO2 + 6H2O

1234 Review Which statement describes how photosynthesis and cellular respiration are interrelated? A. Oxygen is produced during cellular respiration and stored during photosynthesis. B. Carbon dioxide and water released by cellular respiration are used in photosynthesis. C. Photosynthesis releases the energy that is stored during the process of cellular respiration. D. Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.

Transpiration – the loss of water vapor from plants through the stomata under the leaves.

Transpiration is the loss of water through open stomata. Shoulder Partner Transpiration is the loss of water through open stomata. 1. What important plant process is hindered by loss of water? 2. What structure have plants evolved to reduce the loss of water through stomata?

Forms of Plant Reproduction Asexual Reproduction requires only one parent and the offspring is a clone of the parent. Examples include budding, vegetative propagation (stolons and rhizomes), and fragmentation Sporogenesis is reproduction through spores. It may be sexual or asexual. Examples include ferns, moss, and fungi**.

Flowers-Sexual Reproduction Plants that protect their seeds within the body of a fruit are called angiosperms (flowering plants). Flowers are the reproductive structure of angiosperms (sexual reproduction). Gymnosperms have naked seeds in cones

Flower Structure 1. Pistil 2. Stigma 3. Style 4. Ovary 5. Stamen 6. Filament 7. Anther 8. Petal 9. Sepal 10. Receptacle 11. Stem

Male Reproductive Structure The stamen consists of two parts: Anther and Filament The anther is where meiosis occurs to produce haploid pollen The filament is a stalk that supports the anther

Female Reproductive Structure The pistil consists of the stigma, style and ovary The sticky stigma receives the pollen from the anther The pollen grows a tube down through the style Meiosis occurs in the ovary to produce haploid ovules
