Plant Organs & Functions

Learn plant organs & functions! Label flower parts & understand roots, shoots, leaves, and more.

Plant Parts Sort these words and phrases into the correct category based on the plant part they relate to. Roots Anchors the plant Root hairs Absorbs water and minerals Shoots Xylem Phloem Transports glucose, water, and minerals Leaves Stomata Cuticle (waxy coat) Photosynthesis Gas Exchange (O2 CO2) Flower Stamen (Anther Filament) Pistil (Stigma Style) Ovary Fertilization Reproduction Plant Reproductive Organs Label the flower diagram below. Make sure to use these spellings (all lowercase): stigma, anther, ovary, filament, and style. anther filament stigma style ovary Flower Parts Match the parts of the plant reproductive system to their functions. Filament Holds up the anther. Anther Produces pollen (male gamete). Stigma Collects pollen on its sticky surface. Style Transports pollen from the stigma to the ovule. Ovary Produces ovules (female gamete). How does reproduction happen in plants? Ovules from the filament combine with pollen from the stigma. Pollen from the anther fertilizes ovules in the ovary, creating seeds. Seeds from the style fuse with pollen from the petals. Plant Organs Use the matching tool below to pair the names of plant organs involved in transport to the pictures on the left. Xylem Carries water and minerals up from the roots. Phloem Carries nutrients (glucose) from the leaves to other parts. Leaf Produces saccharides (glucose, sugar) through photosynthesis. Roots Absorbs water and minerals and stores extra glucose Flower Ovary Where pollen fertilizes ovules to form seeds. It will become fruit. Sometimes excess sugar produced in photosynthesis is stored in plant roots (ex. potatoes, carrots). What systems interact to allow this to happen? The leaves create starch and the shoot system breaks it down. The xylem carries sugar made in the leaves to the root system. The shoot system carries saccharides made in the flower petals to the root hairs. Leaves produce glucose, which is transported by the phloem to the roots. You put fertilizer in your garden soil. What systems interact in the plant to absorb it? The fertilizer particles are absorbed by the root system and travel up the phloem. Minerals from the fertilizer are absorbed in the roots and transported up the xylem. The fertilizer cannot be taken up into the plant unless it is a liquid because roots only absorb water. The shoot system absorbs the fertilizer and the root system transports it. A student mistakenly claims that water enters the plant through the stomata, small pores in the leaves. Why is he wrong? Select TWO answers. The stomata is a structure that transports glucose. Only the root system of the plant absorbs water. Water is lost out of the stomata, not gained. Water is not needed in the leaf for photosynthesis.
