Chapter 15/16 Test Flashcards
Types of non-vascular plants
~ liverworts
~ hornworts
~ mosses
Non-vascular plants
~ no transport tissue layers
~ no roots; Hair like structures instead (Rhizolds)
~ live in moist areas (moisture to reproduce)
~ low lying
~ no stems; leaves; etc
Vascular plants
~ transport tissue ~ true roots ~ stems ~ leaves ~ xylem ~phloem
Seedless vascular plants
~ true roots
~ spores
- dispersal mechanism
Role of roots
Anchor plants
Seek water and nutrients
Role of stems
Holds plant upright
Seek sunlight
Primary role of leaves
Photosynthesis
Xylem
~ hollow tubes, transports water
~ moves UP from root to top of plant
Phloem:
Transports products of photosynthesis
Living cells
Parts of a flower
Stamen -anther (male reproductive organ) -filament Ovary (female reproductive organ) -Ovule Petals Sepals (tiny leaves underneath flower) Stem Stigma Style
Gymnosperms
-Have seeds (naked seeds, not protected)
-Trees with cones
-seeds gathered in cones
-lose seeds
Ex: woody trees, needles
Angiosperms
-protected seeds
-seeds are kept (retained)
-seeds protected in blossom
-seeds visible
-sometime protected in fruit
Trees, shrubs, broad leaves
Where is pollen produced?
Stigma
Where are the eggs?
Ovules in ovaries
Types of vascular plants
Clubmosses
Ferns
Horsetails
Seed
Contains embryo and food supply
