Kingdom Plantae Seed Plants Mr. Skirbst Life Science Topic 15
-Do not require standing water to reproduce
Seed Plants -Do not require standing water to reproduce -Encase young plants to protect & feed
Seed Structure Consists of: 1- seed coat 2- young plant (embryo) 3- stored food (cotyledon)
Cotyledon Monocot – one cotyledon Dicot – two cotyledons
Reproductive Structures ovule -
Reproductive Structures ovule – female structure containing egg cells pollen -
Reproductive Structures ovule – female structure containing egg cells pollen – male structure containing sperm cells (often with spikes on surface)
Types of Plants gymnosperms -
Types of Plants gymnosperms – “naked” seeds (not covered by ovary)
Types of Plants gymnosperms – “naked” seeds (not covered by ovary) cones – location of reproductive structure (ex. Pine trees)
Types of Plants angiosperms– seed contained in “vessel” (seeds covered by ovary)
Types of Plants angiosperms– seed contained in “vessel” (seeds covered by ovary) flowers – location of reproductive structures (a.k.a. flowering plants)
Gymnosperms 4 phyla:
Gymnosperms 4 phyla: 1- cycads – tropical, palmlike
Gymnosperms 4 phyla: 1- cycads – tropical, palmlike 2- ginkoes – ornamental (seeds stink!)
Gymnosperms 4 phyla: 1- cycads – tropical, palmlike 2- ginkoes – ornamental 3- conifers – cone-bearing, evergreen (like pine)
Gymnosperms 4 phyla: 1- cycads – tropical, palmlike 2- ginkoes – ornamental 3- conifers – cone-bearing 4- gnetophytes – blended characteristics of gymno & angiosperms
Angiosperms -Largest plant group in the world
Angiosperms -Largest plant group in the world -Also called “flowering” plants
Flowers -Contain the reproductive organs
Flowers -Stamen (male)
Flowers -Pistil (female)
Tropism -A plant’s response to a stimulus
Tropism -A plant’s response to a stimulus Response – a reaction to a stimulus
Tropism -A plant’s response to a stimulus Response – a reaction to a stimulus Stimulus – something causing a reaction
2 Types of Tropism 1- Phototropism -
2 Types of Tropism 1- Phototropism – a plant’s response to light
2 Types of Tropism 2- Gravitropism -
2 Types of Tropism 2- Gravitropism – a plant’s response to gravity
Tropism Positive tropism – response toward a stimulus
Tropism Positive tropism – response toward a stimulus Negative tropism – response away from a stimulus
Plants. Plant Characteristics Plants are multi-cellular eukaryotes that produce their food through photosynthesis. (Autotrophs) In addition, many plants.
Plant Kingdom. Plants Multicellular Autotrophs Eukaryotic Have chloroplasts and cell walls Sexual Reproduction.
Pollenation The transfer of pollen from the male reproduction structures to the female structures of the seed plants.
Plant Reproduction & Response to the Environment
Includes: – Mosses (most common) – Liverworts – Hornworts Defining characteristics: – No seeds – No vascular system – Grows low to ground (absorbs nutrients)
Chapter 30 Notes Plant Diversity II: The Evolution of Seed plants.
The seed was major step in the evolution of land plants. It allowed plants to be able to colonize dryer areas of land.
Gymnosperms and Angiosperms. GymnospermsAngiosperms 1. Seeds 2. Leaves 3. Reproduction 4. Example 5. Quick Drawing 1. Seeds 2. Leaves 3. Reproduction.
Plant Life Cycles. Alternation of generation – the process of alternating between asexual and sexual reproduction Seedless plants begin by releasing spores.
Differ from seedless plants because… – Produce seeds, which nourish and protect young sporophytes – Gametophytes form within sporophyte – Sperm forms within.
Everything you need to know about flowers!
Plants 8.4 Gymnosperms and Angiosperms. POINT > Describe gymnosperm characteristics POINT > Identify 4 types of gymnosperms POINT > Describe gymnosperm.
Botany Unit Notes Part II.
22.3 Seed Plants. What are seeds? Every seed contains a living plant ready to sprout as soon as it encounters the proper conditions for growth.
Rants about PLANTS. Parts of a Plant Flower: seed bearing structure Leaves: photosynthetic organ that contains vascular tissue Stem: supporting structure.
Plants! Unit 12. Characteristics of Plant Kingdom 1.Autotrophs (photosynthesis) 2.Multicellular 3.Sessile (do not move) 4. Cell Walls 5. Eukaryotes.
Plant Diversity II: The Evolution of Seed Plants
Plant Reproduction 8 th 16.2 Plant Reproduction. Plant Reproduction Plants reproduce by pollen, spores, or seeds Plants reproduce by pollen, spores, or.
PLANTS Are eukaryotic, multicellular and autotrophic. They must obtain water and nutrients, retain water, transport materials throughout their body, have.
Gymnosperms vs. Angiosperms
GYMNOSPERMS “Naked Seeds” I can: Describe the characteristics of gymnosperms Do Now: List two similarities and two differences between mosses and ferns:
Shane Beyer and Corey Hawk. Angiosperms There are 235,000 species of angiosperms. Angiosperms are vascular, flowering, seed-bearing plants. Angiosperms.
BOTANY The Study of Plants. Part 1: Classifying Plants.
PLANTS. Characteristics 1. Multicellular 2. Eukaryotes 3. Photosynthesis 4. Cells walls have cellulose 5. Most cuticle (waxy, waterproof coating)
Ch 9 Seed Plants Pp Notes 9-1 All seed plants share 2 characteristics. They have vascular tissue and use seeds to reproduce. They all have body.
Sexual Reproduction in Plants. The Seed The seed is the product of sexual reproduction in most plants. The seed contains an embryo, a food supply.
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.
1.) Gymnosperms 2.) Angiosperms The flower helps the plant to reproduce.
Plants. Overview of Plants Characteristics of all plants Multicellular Eukaryotic cells Autotrophs Cell walls made of cellulose.
The Importance of Pollen and Seeds
Seed Bearing Plants.
Seed Reproduction Chapter 9 Notes. Seed Reproduction Plants need to reproduce to carry on their species. Plants reproduce due to the movement of pollen.

Warm Up What are the main functions of a plant’s roots, stems and leaves?
Gymnosperms and Angiosperms. What Do I Study? Seed and Plant Response PowerPoint Gymnosperm Notes Angiosperm Notes Vocabulary Seed Plants Vocabulary Gymnosperms.
Staying “afloat” in air? Strong support tissue, lignin
PLANT REPRODUCTION Chapter 10. Plant Reproduction Plants can reproduce both sexually and asexually In asexual reproduction a new plant can be grown from.
Plants! 7 th Grade Diversity of Living things (Mod B) Unit 2 Lesson 3: Introduction to Plants and 4: Plant Processes.
There are two types of plants that grow from seeds. These are: 1.) Gymnosperms 2.) Angiosperms SEED PLANTS.
The Diversity of Plants
Kingdom Plantae Main Characteristics Cells contain a nucleus Make their own food Cells contain a cell wall Multicellular Can not move from place to place.
