What is the root cap?
It is a protective structure at the end of a root.

What is the difference between a gymnosperm and an angiosperm?

What is a cotyledon?
Seed leaf

What are the main classifications of plants?

Someone says that he saw an avascular plant that was as tall as Shaq. Would you believe him?

What is the stamen, and what two parts make up the stamen?
The stamen is the male reproductive structure of a flower. It is made of the anther and the filament.

What are stomata?
They are small openings that allow for gas exchange in the plant. It also slows down water loss.

Cell wall
300
What are the different types of nonvascular plants?
Mosses, Liverworts, and Hornworts
300
What is the difference between xylem and phloem?
Xylem brings water up, phloem brings food down
300
What are the two types of angiosperms?
Monocot and Dicot
300
What is the difference in the arrangement of the stem between a monocot and a dicot?
Monocots have bundles of vascular tissue scattered throughout the stem. Dicots have vascular tissue arranged in a ring.

What is the difference between sporophyte and gametophyte?
Sporophytes produce spores, and gametophytes produce gametes

What are the different types of seedless vascular plants?
Ferns, Horsetails, and Club mosses

What is the function of the cambium?
It produces new phloem and xylem

What are the four groups of gymnosperms?
Cycads, conifers, ginkgoes, and gnetophytes

What is germination?
Germination is the process of the seed growing by absorbing water from the environment and using stored food.

What is vegetative reproduction?
It is a form of asexual reproduction in which a piece of plant broken off from the main plant can grow into a new plant.

In terms of reproduction, why do nonvascular plants grow in moist areas?
The sperm cells need water to swim to egg cells
500
What is the equation for photosynthesis?
Carbon dioxide + water -----> sugar + oxygen

What is the name of the female reproductive structure in an angiosperm? What are the parts that make it up?
