Reason for angiosperm success |
Structural diversity, efficient vascular system, mutuality with animals for pollination, short generation times. |
|
Difference between angiosperm and gymnosperms |
Angiosperms have fruit and flowers to hold seeds, scatter further. Gymnosperms have naked seeds. |
|
Use of vascular system |
Distribute water and nutrients to cells. |
|
Define cotyledon |
Dot k ow |
|
Define lignin |
A tissue. 25% material in cell walls |
|
Define stele |
Contains vascular tissue in lycophytes |
|
Define stipe |
Stem of algae |
|
Define blade |
Leaf of algae |
|
Define holdfast |
Root structure of algae |
|
Why can algae not live on land |
Need water or support, nutrient absorbed through cell wall from water, sperm needs water |
|
What is a vascular system made up of |
Phloem and xylem |
|
Function of a cuticle |
Reduces dehydration |
|
Define microphyll |
Lycophytes leaves |
|
Types of algae |
Flat, colonial, filaments, macro, micro |
|
Reproduction of algae |
Vegetative, asexual, sexual |
|
Bryophyte |
Moss |
|
Define xylem |
Tissue that conducts water from root to leaves. Has rigid cell wall |
|
Define phloem |
Inside xylem. Transports proteins and sugars do lycophytes have vascular tissue |
|
Define strobili |
Lycophytes cone structures that hold spores |
|
Do lycophytes have vascular tissue |
Yes |
|
Lycophytes |
Oldest phylum of vascular plants . 400mya. Mostly wet environments. |
|
Can lycophytes reproduce without water |
No, sperm needs to swim |
|
How do lycophytes avoid drying out? |
Xylem transports water |
|
How do lycophytes support themselves on land |
Steles provide support |
|
Lycophytes body parts |
Strobili, sporophyte body, microspore on top of megaspore |
|
Types of algae |
Liverworts, hornworts and mosses |
|
Body parts of mosses |
Rhizoids, gametophyte, leaf like structures and capsule that holds spores |
|
Alternation of generations |
Alternate doubling and halving of chromosomes in bryophyte and pterophytes |
|
Define homosporous |
Produce spores of only one kind |
|
Define pterophytes |
Ferns |
|
Dominant pterophytes stage |
Sporophyte |
