OBJECTIVE : IDENTIFY ASPECTS TO CLASSIFY
ORGANISMS
How can we classify organism?

OBJECTIVE : ESTBLISH DIFFERENCES BETWEEN EUKARYA
AND PROKARYA
Eukaryotes vs Prokaryotes

CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 1: PLANT DIVERSITY
OBJECTIVE : CLASSIFY PLANTS ACCORDING TO THEIR
TYPE OF STRUCTURE AND FUNCTION
Root ´s function: 1- Support plants
2- Anchor a plant in the soil and enable it to grow upright and not be blown away by wind
3- Absorb water and minerals from the soil
CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 1: PLANT DIVERSITY
OBJECTIVE : CLASSIFY PLANTS ACCORDING TO THEIR
TYPE OF STRUCTURE AND FUNCTION
Types of roots:
1- Tap root: can store food for the plants
2- Prop root: can provide additional support for the corn plant
3- Fibrous roots spread out and can absorb large amounts of water for the plant
CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 1: PLANT DIVERSITY
OBJECTIVE : CLASSIFY PLANTS ACCORDING TO THEIR
TYPE OF STRUCTURE AND FUNCTION
Stem´s function: 1- Help support the leaves and flowers
2- Have tissues that help carry water and the minerals absorbed by roots to a plant´s leaves
3- Have tissues that transport sugar produce in chloroplasts during photosynthesis

LESSON # 2: PLANT REPRODUCTION
OBJECTIVE : DESCRIBE THE PLANTS CYCLE TO DEVELOP
ANOTHER NEW ORGANISM
How do plants
reproduce
without seed ?
Do all plant
need seed to
reproduce ?
CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 2: PLANT REPRODUCTION
OBJECTIVE : DESCRIBE THE PLANTS CYCLE TO DEVELOP
ANOTHER NEW ORGANISM
Type of reproductions
1- Sexual reproduction: process of sexual reproduction that envolves male sex cells and female sex cell
2- Asexual reproduction: process of sexual reproduction that occurs when only one parent organism is genetically identical to the parent
CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 2: PLANT REPRODUCTION
OBJECTIVE : DESCRIBE THE PLANTS CYCLE TO DEVELOP
ANOTHER NEW ORGANISM
Plant life cycle for seedless plants
1- Gametophyte: produces male and female sex cell
2- Egg: female sex cell
3- Sperm: male sex cell
4- Zygote: beginning of sporophyte stage
5- Sporophytes: New organism that grows on gametophytes and produce spores
6- Spores: produces gametophytes
7- Germination: starts when the spores converts to a gametophytes(new organism)
CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 2: PLANT REPRODUCTION
OBJECTIVE : DESCRIBE THE PLANTS CYCLE TO DEVELOP
ANOTHER NEW ORGANISM
Plant life cycle for seeds plants Gymnosperm
1- Pollen: Is produced by the male cone
2- Pollination: occurs when pollen lands into the female plant structure
3- Fertilization: occurs when the sperm joins with the egg
4- Seed : Place in which the embryo are formed .(tiny sporophytes)
CHAPTER 8 : INTRODUCTION OF PLANTS
LESSON # 2: PLANT REPRODUCTION
OBJECTIVE : DESCRIBE THE PLANTS CYCLE TO DEVELOP
ANOTHER NEW ORGANISM
Plant life cycle for seeds plants Angiosperm
1- Pistil: female reproductive organ in flowers
2- Stamen: male reproductive organ in flowers
3- Fertilization : occurs when the pollen joins to the ovary
4- Embryo: it is formed after fertilization occurs . It is found in the seed
5- Seed: it is produced from the embryo. New identical organism genetically.
