The Plant Kingdom- Introduction Flashcards
Name 7 general traits between plants
- eukaryotic
- multicellular
- cell walls made of cellulose (a tough fibrous substance)
- contains chlorophyll
- reproduces sexually or asexually (sometimes alternating between the two) via seeds or spores
- most are terrestrial (live on land)
- sessile (once they germinate they remain in one place)
Name the three non-vascular plants
- Bryophytes (mosses)
- hornworts
- liverworts
Name the 5 vascular plants
- whisk ferns
- pteridophytes (ferns)
- horsetails
- lycopods
- seed plants
What is vascular tissue
It refers to special cells in organisms that combine to form structures that carry substances around the body
What are the two types of vascular tissue in plants
Xylem- which carries water up from the roots to the stem and to the leaves where it is needed for photosynthesis
Phloem- which carries the food made in the leaves during photosynthesis down the stems into storage at the roots
What’s the difference between non-vascular plants
They don’t have any of these systems to transport food Dan water instead they are very small (only a few layers thick) and so they can rely on simple diffusion to transport substances around the plant
Learn the different classification for bryophytes, Pteridophytes, gymnosperms and angiosperms
In gallery
Name the two main seed-bearing vascular plants
Gymnosperms and angiosperms
How are seeds formed
When pollen grains (sperm cells) fuse with ova (egg cells) and germinate to form a new adult
What’s the difference between gymno and angiosperms
G- cone bearing
A- flower bearing
Give 3 examples of gymnosperms, dicots and monocots
G- Cycads, pine trees and other conifers
D-daisies,roses and peas
M- grasses, aloes and lilies
Name the two types of angiosperms
MonoCotyledons and dicotyledons
Give 3 characteristics of monocots and dicots
M- parallel veins on leaves
- flowers in parts of 3 or 6
- have tepals
D- breached veins on leaves
- flower parts in 4 or 5
- have both sepals and tepals
