chloroplasts, cellulose
It is believed that modern day plants most likely evolved from what?
green algae
Directions: True or false? If false, correct the statement.
Some scientists believe that plants evolved from green algae because they both contain similar chlorophyll and have cell walls.
True
Plant cells are surrounded by cell walls. List the three things a cell wall provides.
- Protection
- Structure
- Shape
What is a cuticle?
A waxy, transparent layer that surrounds the epidermis of a plant
Directions: Answer the statement with the best available option.
The main job of a cuticle is to…

B. Provide structure
C. Scare off predators
D. Serve as protection
A. Keep in moisture
Most plants have _______ and _______ to transport water and nutrients.
roots, stems
What are the two main divisions of plants?
- Nonvascular
- Vascular
Directions: After being provided the definition, list the plant classification.
- Do not have true roots, stems, or leaves
- Need to live in or near water (take in water through osmosis)
Non-Vascular Plants
List three examples of non-vascular plants.
- Moss
- Liverwort
- Hornwort
What is the definition of a vascular plant?
A plant that has vascular tissue and roots, stems, and leaves
Directions: Answer the statement with the best available option.
Xylem is a vascular tissue that moves…
A. Conifers
B. Food
C. Water
D. Spores
C. Water
What is a phloem?
A tissue in vascular plants that carries (moves) food and nutrients
Directions: True or false? If false, correct the statement.
The two main classifications of vascular plants are gymnosperms and angiosperms.
False. The two main classifications of vascular plants are seedless plants and seed plants.
How do seedless plants reproduce?
By spores
What are some examples of seedless vascular plants?
Ferns, horsetail, and club mosses
A: Gymnosperms
B: Angiosperms
This diagram is an example of what?
A seed
What are the five parts of all seeds?
- Plumule (future leaves)
- Hypocotyl (stem)
- Radicle (future root)
- Cotyledon (stored food)
- Seed coat (protective coating)
List two traits that only Gymnosperms possess.
- They produce seeds in cones
- They have needle-like leaves
What are some examples of gymnosperms?
- Conifers
- Ginkgoes
- Cycads
- Gnetophytes
Directions: After being provided the definition, name the plant classification.
- Produce seeds in flowers
- Seeds are eventually contained in fruits
Angiosperms
Clarifier:
Angiosperms are one of two members of the category seed plants, meaning they are vascular.
Monocots and dicots are the two broad groups of ___________ plants.
flowering
What are the differences between monocots and dicots?
Hint: Think about the veins, the flowers, the cotyledons, the vascular tissue, and the roots
List 5-10 examples of monocots.
List 5-10 examples of dicots.
Is this an image of a male or female cone?
female
What are the three main functions of roots?
