Chapter 1 Test Study Guide
Lesson 1- How are plants grouped?
Plants are grouped by how they reproduce (make more seeds).
Group 1- Plants that make seeds
Example 1: Flowering plants


Flowering plants make seeds on the flower
Examples: sunflowers, cacti, fruit tree
Example 2: Conifers
 Conifers make seeds inside a pine cone
 Conifers DO NOT have flowers
 Examples: pine trees
Group 2- Plants that do NOT make seeds
Example 1: Ferns



They have roots, stems, and leaves but no flowers or seeds
They reproduce by making tiny cells that can grow into new plants
These are called spores
Example 2: Mosses
 They do NOT have stems, roots, or leaves
 They reproduce by making tiny cells that can grow into new plants
 These are called spores
Lesson 2- What are the parts of a flower?
Sepal leaf like part that protects the flower bud and is usually green
 it stays with the flower after it has bloomed
Pistil this part of the flower that contains the ovary and ovules that makes
eggs that grow into seeds.
 Seeds are formed in ovules inside the ovary
 The pistil is sticky at the top, and traps the pollen
Stamen Makes the pollen(yellow powder-like substance that contains sperm for
fertilization)
Petal Colorful part that attracts the insects
 The petals protect the parts of the flower that make seeds
Lesson 3- How do flowers and seeds make fruits?
Pollination Movement of pollen from stamen to the pistil
 Insects, small animals, water, wind help in pollination
 Pollination occurs when an insect or wind take the pollen from the
stamen of one plant and brings it the sticky pistil of another plant
Fertilization The combination of sperm from a pollen grain with an egg to form a
seed
 Pollen lands on the pistil and forms a thin tube to the ovary, where the
sperm from the pollen combines with an egg to make seeds

Monocots & Dicots
*All flowering plants are either monocots or dicots*
Monocot



Has 1 seed leaf
does NOT split in half
Example: corn, wheat, oats
Stored food is around seed leaf
Dicots Has 2 seed leaves
 Splits in half
 Example: beans, peas, maple seeds
SEED!
Lesson 4- What is the life cycle of a flowering plant?
1. Dormant seed- the resting stage of a seed (beans that we classified)
2. Germinating seed- FIRST, a root pushes through seed coat and grows
downward to anchor the plant. SECOND, the stem grows upward and leaves
form to make food for the plant
3. Seedling – (baby plant) more leaves grow from the buds on the stem as the
plant grows taller
4. Mature plant- need water, carbon dioxide, the right temperature, and
energy from sunlight, and may need soil to grow. The mature plant blooms
(has flowers or fruits)
