9 Roots: Anchors plant by keeping it firmly in place. Absorbs water and minerals. Stem: Holds up the plant. Transports water, minerals, and nutrients to rest the plant. Flower: Where pollination and reproduction takes place. Roots Stem Leaf Flower Photosynthesis Leaf: Where photosynthesis (food making) takes place. Parts of a Plant Pollination Plant Responses Plant Responses

10 ROOTS Root hairs: absorbs water and minerals Root cap: pushes the root through the soil. Grass is a fibrous root. Carrots are taproots where starch is stored. Roots Stem Leaf Flower Photosynthesis Pollination Plant Responses Plant Responses

11 Xylem Cells: connecting tubes that carry water and minerals from the soil. Stem Phloem Cells: tubes that carry nutrients from the leaves through the stem and down to the root. The stem is like the highway system of the plant, transporting minerals, nutrients, and water throughout the plant. Woody plants, like roses and trees, live for many years. Nonwoody plants, like dandelions, live for only one season. Roots Stem Leaf Flower Photosynthesis Pollination Plant Responses Plant Responses

12 Leaf Veins: the transport system of the leaf. Petiole: an extension of the xylem and phloem tubes from the stem. Blade: the broad, flat part of the leaf. Inside of a Leaf Upper Epidermis: protects the leaf from drying off. Lower Epidermis: protects the leaf and allows for the exchange of gases. Cells: where chloroplasts exist and food making occurs Chloroplasts: contains the chlorophyll, which gives the leaf color.

13 Flower Petals: the colorful part of the flower. Stamen: Male part that holds the pollen. Pistil: the female part of the flower. Stigma: sticky part on the top of the pistil to which pollen grains stick Ovule: Produces the female sex cells and becomes the seed.

14 Carbon dioxide water Carbon dioxide sunlight oxygen Sugar=energy Photosynthesis : sunlight+ carbon dioxide+ water= sugar and oxygen Roots Stem Leaf Flower Photosynthesis Pollination Plant Responses Plant Responses

15 Pollination Roots Stem Leaf Flower Photosynthesis Pollination Plant Responses Plant Responses Colorful petals attract insects and other animals to the nectar. Pollen rubs off of stamen onto insect or animal. Insect or animal rubs pollen onto stigma. Pollen travels down pistil and becomes fertilized in the ovary. Ovary enlarges and becomes a fruit. The fruit splits open and releases the seeds.

16 Plant Responses Thigmotropism: plants response to touch, like the tendrils of a pea plant. Hydrotropism: plants response to the need for water. Phototropism: plants response to the need for sunlight. Geotropism: plants response to gravity by growing toward the center of the earth.
