Science 8 Q1 - Plants

Xylem and Phloem

Specialized Tissues/Vascular Bundle Tissues

Transports water and minerals upward from the roots to the leaves, and are made of dead hollow cells that form tubes.

Xylem

Transports sugars and fruits, which were produced in leaves, to all parts of the plant, and are made of living cells, including sieve tubes and companion cells

Phloem

Roots, Stem, Leaves, Flowers, Fruits

Parts of the Plants

Absorbs the water and minerals from the soil, stores food for future use, anchors the plant firmly to the soil and provides support, and develops new plants from the roots of the old plant

Roots

Provides strength and support for the buds, flowers, leaves, and fruits

Stem

makes food with the help of sunlight, carbon dioxide, and water through photosynthesis, helps in reproduction such as in Bryophyllum, a group of sprout leaf plants, helps in evaporation in aerial parts of the plants by transportation

Leaves

Helps in sexual reproduction of the plants, and stimulating pollination in plants and fertilization of the ovule

Flowers (functions)

Sepals, Petals, Stamen, Carpel

Parts of the Flowers

Green parts of the flower, found below the sepals that protect the flower buds from injury

Sepals

Colorful parts of the flower found above the sepals that help in pollination

Petals

Consists of an anther and filament. They are the male reproductive part of a plant producing male sex cells or spermatia

Stamens

Consists of stigma, style, ovary. They are the female reproductive part of a plant producing female sex cells or ovules

Stamens

They are the ripened ovary found in flower after fertilization. The ovules after fertilization make the seed, which is then fertilized to form new plants

Fruits

Protects growing seeds, and helps in the dispersal of seeds and in plant reproduction

Fruits (functions)
