Dicotyledons & Monocotyledons Angiosperms are divided into two groups The basic distinguishing feature are embryonic leaves (coytledons) Cotyledons are found in the seeds of these plants © 2008 Paul Billiet ODWSODWS
Dicotyledon seed Seed coat or testa Cotyledons acting as a food reserve Plumule (to become the first true leaf) Radicle (to become the first root) Micropyle © 2008 Paul Billiet ODWSODWS
Monocotyledon seed Seed coat Cotyledon Plumule Radicle Endosperm (food reserve) © 2008 Paul Billiet ODWSODWS

Monocot vs. Dicot Flowering Plants. IB Assessment Statement Outline three differences between Monocotyledons and Dicotyledons.
Getting Started 1. What is the function of a seed? 2. Make a list of seeds that are edible. 3. Why are some seeds a good source of nutrition?
NAME THIS PLANT?. Ch. 28 Plant Evolution & Classification The first plants were thought to be water plants Algae. Other plants evolved from algae. Pg.
Seeds vs Spores A seed is an embryo of a plant encased in a protective covering and surrounded by a food supply.
Plant Classification – Plant groups. KINGODOMPHYLUMCLASS Plantae / Plants (multicellular organisms that make their own food by photosynthesis) Bryophyta.
Chapter 21. Plant: multicellular, photosynthetic eukaryotic organism that contains tissues and organs with specialized structures and functions Plants.
Classification of Plants Plant Kingdom Flowering Plants Non-flowering Plants.
Classification of Plants. 2 The Plant Kingdom (main characteristics) 3) They have chloroplasts in the cells 2) Plants make their own food by photosynthesis.
Alternation of Generations Plant life cycles have two alternating generations: a diploid phase (2N) and a haploid phase (N) During alternation of generations,
Life Science Chapter 11. Plant Classification Kingdom Plantae Kingdom Plantae Phylum: Bryophyta – Mosses, Liverworts & Hornworts Phylum: Bryophyta – Mosses,
Plant Geneology & Taxonomy I. NON-VASCULAR PLANTS No special system of vessels to transport fluids internally. Examples : mosses, liverworts.
Plants. Overview of Plants Characteristics of all plants Multicellular Eukaryotic cells Autotrophs Cell walls made of cellulose.
Vascular Plants. It is essential for students to know that organisms in the Plant Kingdom are classified into groups based on specific structures. All.
Biology AHSGE Standard X- Kingdom Plantae. Eligible Content CONTENT STANDARD 10. Distinguish between monocots and dicots, angiosperms and gymnosperms,
Plant Diversity Botany = the study of plants. General Plant Charactertistics ●Living things that have roots, stems, and leaves ~ some have flowers ●Eukaryotes.
KINDS OF PLANTS. NONVASCULAR PLANTS Mosses are often found next to streams, coastlines and other moist places. They will can be found in odd places as.
CHAPTER 9 “INTRO TO PLANTS” p. 240 Plants -285,000 + species of plants. -All have tissues and “organs”. Plants must have: cell walls -for support. chloroplasts.
Plant Review Chapter 7 Practical Science II. Adapting to Life on Land Plants are multicellular eukaryotes with a cuticle and cells surrounded by walls.
SEED PLANTS Characteristics of Seed Plants Most seed plants have leaves, stems, roots, and vascular tissue Reproduce by seeds, which contain an embryo.
Science AHSGE Standard III-2 Kingdom Plantae. Kingdom Plantae Multicellular Eukaryotic Autotrophic/producers- Make their own food Chlorophyll- green pigment.
Plant Evolution. Adaptations Cuticle alternation of generations specialized tissues.
Plants!!!! Multi-cellular eukaryote that produces its own food in the form of glucose through the process of photosynthesis All plants are autotrophic.
Kingdom Plantae. They are complex, multicellular organisms The cells have a cell wall, a nucleus and other organelles They have chlorophyll and can make.
Angiosperms PA Standards 3.3.7A, 4.7.7A. Angiosperms 1) “Flowering Plants”
PLANT CLASSIFICATION. PLANT KINGDOM THERE ARE 4 GROUPS PLANTS WHICH MAKE SPORES Mosses and liverworts Ferns PLANTS WHICH MAKE SEEDS Conifers Flowering.
GROUPS OF PLANTS. NON-VASCULAR PLANTS Do not have a system to transport water and nutrients Get water through diffusion Small- because they cannot move.
Multicellular, Eukaryotes Cell walls made of cellulose Waxy waterproof cuticle Autotrophs Photosynthetic with chlorophyll.

Characteristic Structures of Various Groups of Plants Non- Vascular Plants Vascular Plants Spore- Producin g Seed- Producing Cone- Bearing Flowerin g Plants.
Plant Test Tomorrow Format 36 m/c 5 Is it a tracheophyte or bryophyte? 4 Is it a gymnosperm or angiosperm? 5 Is it a monocot or dicot? What.
Seed Plants Leaves- where the food making process (photosynthesis) occurs.
Introduction to Plants. A. Obstacles to living on land Harsh ultraviolet light oxygen produced in oceans converted to ozone Harsh ultraviolet light.
Seeds Monocot vs. Dicot Accelerated Biology. Seed Anatomy Seed coat – protects embryo from injury and harsh environment Seed coat – protects embryo from.
Standard Compare the characteristic structures of various groups of plants – including vascular or nonvascular, seed or spore-producing, flowering.
Review of Plant and Animal Phyla. Bryophyta Short stature plants such as mosses, liverworts, and hornworts Non-vascular because no xylem or phloem No.
Plant Diversity. Kingdom Plantae Multicellular eukaryotes Cell walls made of cellulose Photosynthesize using chlorophyll a and b Most are autotrophs.
