Mo4-L1: Key Concept Organizer
Directions: Circle the term in parentheses that correctly completes each sentence.
1. Roots, stems, and leaves have functions that help (plants/animals) survive.
2. (Prop roots/Taproots) help support the plant.
3. (Prop/Fibrous) root systems consist of many small branching roots.
4. Roots (anchor/detach) a plant in the soil and enable it to grow upright so it won’t be blown away by
wind or be carried away by water.
5. Roots also absorb water and minerals from the soil, which plants require for (cellular processes/support).
6. (Roots/Stems) help support the leaves, and in some cases flowers, of a plant.
7. In some plants, such as cacti, stems store (water/food) that the plants use during dry periods.
8. Some cells in a leaf contain many chloroplasts where light energy is converted into chemical energy,
which is stored in (proteins/sugar) during photosynthesis.
9. Trees and shrubs usually have (herbaceous/woody) stems; weeds and many vegetables have
(herbaceous/woody) stems.
10. Leaves also are involved in the exchange of gases (with the environment/between plants).
Mo4-L1: Key Concept Check
Directions: Change the underlined word(s) to make each false statement true. Write your changes on the
lines provided.
1. Plants that lack specialized tissues for transporting water and nutrients are vascular plants.
2. The divisions of nonvascular plants include roots, stems, and leaves.
3. Rhizoids help anchor a moss and repel water.
4. The thallose liverwort is uneven and lobed.
5. A leafy liverwort has large, leaflike structures attached to a central stalk.
6. A hornwort’s reproductive structure resembles a large bell.
7. Vascular plants have specialized tissues, called vascular tissues, that absorb water and nutrients
throughout the plant.
8. Ferns, horsetails, and club mosses produce seeds.
9. A fern’s fronds grow from an underground stem called a rhizome. Ferns usually grow in sunny locations.
10. Horsetails also are called scouring rushes due to an abrasive mineral called silica in the leaves.
