WN 5th grade Science ~ Roots, Stems, and Plants

Quiz 1 ~ 8/31 and 9/1
Root that is long, thick, and goes straight down
ex: carrot, dendelion
Vascular Plant
Plant that has xylem and phloem tubes
Plant tissue inside the root that transports water and minerals
Aerial Root
Root that grows above the ground from the stem of a plant
root cells that store food
outside covering of a root;
helps root absorb water
Fibrous Root
Fine roots that branch out and cover a large area (ex: grasses)
Plant tissues that carry food from one part of the plant to the other
Primary Root
1. Main root;
2. Connects to the stem
Prop Root
Aerial root that helps support plant
1. Underground foundation of a plant;
2. Anchors plant in the soil;
3. Absorbs water and minerals
Root Cap
Mass of cells at the end of the root that protects it as it grows and puches its way through the soil
Root Hairs
little hairs found on roots;
help absorb water and minerals
Secondary Roots
Any root that comes off the primary root
1. Supports the plant's leaves and flowers (necessary for leaves to get light from the sun for photosynthesis)
2. Part of the plant that connects its roots and its leaves
Transport System of a Plant
As a group, the xylem and phloem cells form the transport system of a plant
Functions of a Root System
A root system stores food and absorbs water and minerals.
Differentiate between Taproot and Fibrous Root
Taproot: root that is long, thick, and goes straight down. ex: carrot, dendelion
Fibrous Root: fine roots that branch out and cover a large area ex: grasses
Examples of Edible Roots
carrot, beets, potatoes, and radishes
Types of stems
1. Woody: hard stems covered by bark, not easily bendable
2. Herbaceous: green soft and bendable stems; ex: buttercup
Modified Stems
Modified stems
1. Tuber stem: potatoes
2. Bulb stem: onion
3. Rhizome stem: ginger
4. Succulent stem: cactus
Edible Parts of the Plant
fruits, seeds, roots, leaves, flowers, stems
Importance of Plants
1. Primary source of food for people and animals
2. Produce oxygen
3. Help keep us cool
4. Renew the air
Plants provide...
1. Slow wind speed
2. Shelter for wildlife
3. Beautify surroundings
4. Furnishings and buildings (wood)
5. Plant sap is used for resins and latexes
Annual Plants and Trees
Annual plants and trees grow, make flowers fruit, and seeds all in one season. They do NOT return the following year.
Examples ~
Plants: tomato, pansy
Biannual Plants and Trees
Biennial plants and trees need 2 years to complete full lifecycle.
Examples ~
Plants: forget-me-not, parsley
Perennial Plants and Trees
Perennials come back year after year without having to be replanted.
Examples ~
Plants: tulip, rose
Deciduous Plants and Trees
Deciduous plants and trees lose their leaves during the Fall and bloom in Spring.
Examples ~
Trees: Oak, Maple
Evergreen Plants and Trees
Evergreen plants and trees
