Plants Unit 3 Lesson 2

Objective: 1. Identify the word lifecycle and Embryo. 2. Arrange lima bean life cycle. 3. Identify Maturity and Germination stages.

Vocabulary:  Germination  Maturity  Life cycle  Embryo

Warm up  Where do plants come from? Seed

embryo What is an embryo ?

1-Describe each stage of the radish’s life cycle 2- Are they in order? A B C D Sprouting germination Mature plant Like a grown up which makes new seeds Seed

Stage 1 Stage 2 Stage 3 Stage 4

What does life cycle mean? life cycle The series of stages that a living thing goes through as it develops is called a life cycle. Most of our food comes from plants. seeds Most plants grow from seeds.

How does a seed grow?  Video Video

Exit Slip: In your copybook name each stage of plant life cycle. Choose from these vocabs: Germination Sprouting Seeds Maturity

H.W 1 Active Reading sheet. Write vocab words germination and maturity

Bring different seeds from home for next lesson from the food you eat Bonus

Meanings :  Germination = When seed sprouts and the embryo seed starts to grow.  Maturity = When plant grows to it’s full size. Mature plants can make new seeds.

Lesson 2 Warm up: Thinking ……  What was the 1 st step in the life cycle of a bean plant?  Where is a seed formed? Flower and Cones  How is the seed produced? Sexual Reproduction

Flowers and Cones  What is reproduction? 1. Increase in number Or 2. Getting more of the same kind

Reproduction = to make – again. MotherFather Puppies

Soooo.. How are seeds formed? 1.Male share (sperm cells) 2.Female share (egg cells) Fertilization When the male and the female sex cells join together  Fertilization sexual reproduction so this called sexual reproduction So when it comes to flowers … Which part is the female and which is the male ? video

Flowers and Cones Identify the parts of a flower. Petal Stamen Stem Pistil Anther Male Male part of a flower Female Female part of the flower

Flowers and Cones Fertilization Sexual Reproduction Egg cell + Sperm cell = Embryo (in this case the embryo inside plant seed) 1)Some have both organs in same structure 2)Others have both organs on 2 separated structures meansmeansmeansmeans

Exit Slip 2 : Pistil Anther Stamen petal Stalk(stem)

HOMEWORK 2 1. Write vocab word fertilization from the glossary 1. Study the flower diagram page 120 from your books

Lesson 3: What is fertilization? Reproduction is done in 3 steps in plants : 1. Pollination 2. Fertilization 3. Seed Dispersal Video 1 Video2

1-Power of pollination Pollination Process of pollen moving from a male plant part to a female plant part. 1)Wind 2)Animals Wind can blow the pollen Brightly colored flower petals attract pollinators e.g Bees, Birds, Butterflies 1)Wind Video3)Water

Pollination 1. When the pollen on the stamen rubs off on the butterfly. 2. When the butterfly visits the next flower, the pollen may drop off and fall on the pistil. 3. Now the flower will be pollinated.

Exit Slip 3 : List three ways of pollination:

2-Fertilization

3-Seed Dispersal How can a plant’s seeds be spread from place to place? 1) 2) 3) Video

Exit Slip 4 : List three ways of seed dispersal:

Classwork:

Lesson 4: Asexual Reproduction  Some plants grow from seeds and other plants grow from structures called spores.

Classwork :

Exit slip: (in copy book)  Give one word :  -A reproductive structure of some plants, such as mosses and ferns that can form a new plant.
