GROWTH AND ADAPTATION
![Page 2: PLANTS GROWTH AND ADAPTATION. Plants have 3 organs: 1. Leaves 2. Stems 3.Roots Draw the picture and Identify Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062322/5697bfb71a28abf838c9ec83/html5/thumbnails/2.jpg)
Plants have 3 organs:
• 1. Leaves
• 2. Stems
• 3.Roots
• Draw the
picture and
Identify
Structures.

LEAVES
• 1. Site of photosynthesis- chloroplasts in top layer of leaf.
• 2. Site of gas exchange- stomata in underside of leaf

STEMS
• 1. Provide structure for the plant
• 2. House vascular tissue– A. Xylem- tissue that draws water and
minerals up from roots– B. Phloem- tissue that distributes sugar from
leaves to rest of plant

ROOTS
• 1. Anchor plant to ground
• 2. Absorb water and minerals from soil

Plant Reproduction
• Plants have male and female reproductive parts.
![Page 7: PLANTS GROWTH AND ADAPTATION. Plants have 3 organs: 1. Leaves 2. Stems 3.Roots Draw the picture and Identify Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062322/5697bfb71a28abf838c9ec83/html5/thumbnails/7.jpg)
Female reproductive structures
• The pistil -consists of the:
1.Stigma
2.Style
3. Ovary (contains the
ovule, or plant egg)

Male reproductive structures
• The Stamen –consists of:– 1. Anther– 2. Filament– 3. Pollen (plant sperm)

Plant Genetics
• Pollen is the male plant sex cell, or GAMETE.• The Ovule is the female plant sex cell, or
GAMETE.• Gametes are HAPLOID- meaning that they each
contain half the genetic material necessary to produce offspring.
• After fertilization, a genetically complete organism is formed, with all the genetic information necessary for survival and reproduction.

Fertilization
• Plant fertilization and seed distribution is carried out by insects, wind, and animals.

PHOTOSYNTHESIS
• Photosynthesis occurs in the chloroplasts
• O2 is released and CO2 is absorbed through the stomata
![Page 12: PLANTS GROWTH AND ADAPTATION. Plants have 3 organs: 1. Leaves 2. Stems 3.Roots Draw the picture and Identify Structures](https://reader035.vdocuments.mx/reader035/viewer/2022062322/5697bfb71a28abf838c9ec83/html5/thumbnails/12.jpg)
What happens during photosynthesis?
• Sunlight provides the energy for the chloroplast to convert carbon dioxide and water to glucose and oxygen.
• 6CO2 + 6 H2O C6H12O6 + 6O2

TEACHER NOTESBegin with “BrainPop”- “Plant
Growth” and then “Photosynthesis”• Have students create a book mark with the
plant information.– Have them draw the leaves, stems and roots
on one side, and define the terms on the other side.
– Have them return their bookmark to their science teacher for extra credit!
