You will learn about vascular and non-vascular seedless plants.
After completing this tutorial, you will be able to complete the following:
What are some of the everyday uses of plants?
~ We commonly use various plants for a wide variety of purposes, including as food, construction materials, and a source of oxygen.
In what type of environment do most non-vascular plants live?
~ Most non-vascular plants live in humid environments, often in the soil or on trees or rocks.
What are some examples of vascular seedless plants?
~ Some common types of vascular seedless plants include ground pines, ferns, and horsetails.
Why are the seeds of gymnosperms referred to as "naked"?
~ The seeds of gymnosperms are often referred to as "naked" because they do not develop enclosed within the ovary of a flower. Since the ovary develops into a fruit, the seeds of gymnosperms are not enclosed within a fruit, as other types of seeds are.
What is the function of cotyledons?
~ A cotyledon either absorbs the nutrients held within the seed, or contains nutrients itself. The nutrients are passed to the seedling as it grows, until it is able to produce its own leaves to carry out photosynthesis.
