True or False: Gymnosperms are usually large trees and the seed is in a cone.
True: Gymnosperms are usually large trees and the seed is in a cone.

The stem transports what substance through the conducting vessels?
The stem transport substances (nutrients and water) through the conducting vessels.
100
What 2 things do roots absorb and through what?
Roots absorb water and dissolved mineral salts (raw sap) through the root hairs.
BONUS: The stomata of the leaves absorb carbon dioxide (CO2).
100
What are stomata? What do they do?.
Stomata are little structures that are open and close & they're located under the leaf. They are open during daylight to allow photosynthesis to occur. They also exchange gases and moisture if needed during the evening.

How do ferns, mosses and liverworts reproduce? BONUS 200: What is the difference between the reproduction of ferns VS mosses and liverwort?
Mosses and liverworts reproduce by spores produced in the capsules located at the end of the celluloid.
Ferns reproduce by spores produced by sporangia, very small spore-producing structures that group together to form the soil.

The red maple tree is a flowering plant. The longleaf pine tree is a nonflowering plant. Both trees go through various stages in their life cycles. Which stage occurs in the life cycles of both trees?
They both make seeds
200
This part of the plant holds it upright and containes tubes responsible for transporting nutrients and water throughout the plant.
The stem
200
The diagram below details the process of photosynthesis.
What is the name of the process outlined in part E of the diagram above?
cellular respiration
200
What are tubers? Give an example.
Tubers are underground stems that store nutrients and can become a new plant (potato).
200
How does the pollination process occur? Give 3 examples.
The pollination process occurs thanks to the wind, animals (insects and birds) or water.

Name the two main classifications of plants and compare them.
Vascular - plants with roots, stems, & leaves
Nonvacsular - grow 10cm or less
300
Where does photosynthesis take place?
Leaves contain structures called chloroplasts. Photosynthesis happens within them.
300
How do nutrients and water travel up the plant?
Nutrients and water travel from the roots through the stem to the leaves.

The town of Pleasantville experienced a very hot, dry summer with very little wind. How can these conditions affect the reproduction of seed plants?
Pollen travels on wind and water, so it would not be able to travel very far.
300
What is germination?
Germination is when a new plant sprouts from a seed.

Millions of honeybees have vanished from their hives throughout the country recently. No one is sure why the bees have disappeared. However, many people are concerned. Why?
Bees pollinate many flowering plants.

The magnolia tree is a flowering plant. The pine tree is a nonflowering plant. What is the order of events in the life cycles of both plants?
pollination, fertilization, seed, seed dispersal
400
Saflowera has a small seed that has a thick shell. Birds need to crack open the shell to eat the seed. Which type of beak would be best suited to eating safflower seeds?
Short & strong
400
As you walk past a field of sunflowers, you notice the flowers are all facing the same direction. This is an example of what?
phototropism - they always face the sun
400
What is fertilization? How does this form seeds and fruit?
Fertilization is when the pollen grain travels to the ovary and unites with the ovule. The ovule fertilized by the pollen grain becomes the seed. The ovary becomes the fruit that protects the seed.
500
What are the 2 characteristics of Ferns?
True roots, stems, and leaves and they have spores on the top of the fronds to reproduce.
500
Name 3 plant organs and 1 function of each.
Roots: Absorb water & mineral salts from the soil, Store food reserves (carrot, beet...), They anchor the plant to the ground.
Stem: Keep the plant vertical to support it, Transport substances (sap) through the conducting vessels, Store food reserves.
Leaves: Photosynthesis, Gas exchange
500
What adaptation keeps a cactus plant from losing water?
Flat, waxy leaves.

Fill in the blanks: Asexual reproduction involves only one _________ and the offspring is ___________ to do it.
Asexual reproduction involves only one parent and the offspring is identical to do it.

The Empress tree’s flowers have blue and violet markings. What is the main role of the colored markings on the flowers?
To attract insects to carry pollen
