Chapter 5 - Plants Flashcards
Second Quarter
Plants may be classified by their stems:
- Vascular plants
- Nonvascular plants
They have organized transport systems for foods, nutrients, and water in their stems.
Vascular plants
They do not have an organized transport system or food, nutrients, and water in their stems.
Nonvascular plants.
They can be seedless or seed-bearing plants.
Vascular plants
They have no “true” stem.
Nonvascular plants
These include the flowering plants (angiosperms) and the nonflowering plants (gymnosperms).
Seed-bearing plants
What do you call the seed-bearing plants?
angiosperms
What do you call the seedless plants?
gymnosperms
The term angiosperm comes from the Greek word:
“angeion” (case) and “sperma” (seed)
The process by which pollen is transferred from the male reproductive part to the female reproductive part of a plant.
Pollination
Flowering plants are traditionally divided into:
Monocots and dicots
These are storage tissues that nourish the developing seedling until the seedling grows its own leaves and can’t produce its own food through photosynthesis.
cotyledons
What do you call the pattern of veins in leaves?
Leaf Venation
Factors that determine the differences between monocots and dicots:
- cotyledon
- leaf venation
- flower part
- vascular tissue arrangement
- root
The word gymnosperm comes from the Greek word:
“gymnos” (naked) and “sperma” (seed)
The seeds of gymnosperms are contained in structures called ____________.
cones
The parts of ferns that resemble leaves.
fronds
Fronds are divided into two main parts:
stipe and blade
the fern “stems”, which contain the vascular tissues or the xylem and the phloem.
rhizomes
They from on the rhizome or even on the stripe of a fern. They grow down and act as their support.
roots
They are round or elongated structures found on the undersides of fronds.
Sori (singular: sorus)
Vascular tissue of plants responsible for delivering water and minerals from the roots to the aerial plant part.
xylem
Vascular tissue of plants responsible for transporting food and nutrients from the leaves to other plant parts.
phloem
Nonvascular plants are usually small. Water and nutrients are obtained via transport processes called ___________ and ___________.
osmosis and diffusion
(kinds of nonvascular plants)
Small and flowerless plants that grow as clumps or mats in moist and shady places.
Mosses
(kinds of nonvascular plants)
They grow in mats or clumps like Mosses do. They may be found on the ground rocks, trees, and other places particularly. in humid areas. They also exist in Arctic regions and deserts.
Liverworts
(kinds of nonvascular plants)
They grow in moist places. They got their name from their slender and horn-shaped spore capsules where they produce their spores.
Hornworts
The act of using plants, animals, or even bacteria to restore the environment. It is a method used to clean up rivers and restore small areas of deforested land.
Bioremediation
