Term
| What are the 2 different types of plants |
|
Definition
| angiosperms and gymnosperms |
|
|
Term
| what are the 3 common forms of angiosperms |
|
Definition
| lilies, orchids,and lupines |
|
|
Term
| summarize the plant reproductive cycle |
|
Definition
1. production of sex cells from Ovary and Anther
2. Pollen attaches to stigma of plant, forms a pollen tube and travels down into the ovary
3. Fertilization occurs and zygote forms
4. Embryo develops enclosed within a food supply and seed coat
5. seeds are dispersed
6. seeds grow into a sporophyte |
|
|
Term
| What is the alteration of generations? |
|
Definition
| The variation in genes between offspring and parents produced by the parents passing on their haploid number of chromosomes in diploid form. ( alternation between plants being the diploid and then the haploid). |
|
|
Term
| how do angiosperms and other organisms interact with each other |
|
Definition
| Human Agriculture is based on angiosperms. Through artificial selection and genetic engineering humans have influenced plant evolution. Pollination by animals has affected angiosperm evolution ( each has evolved to suit each other) |
|
|
Term

|
Definition
|
|
Term
| What are the 3 types of tissue layer |
|
Definition
Mesoderm- organ tissue
endoderm- digestive and urinary tract
ectoderm- skin |
|
|
Term
| What is bilateral and radial symmetry |
|
Definition
Bi- if split in half down the top the organism is symmetrical
Ra- from top to bottom the organism can be divided into 4 symmetrical quadrants |
|
|
Term
| What is the invertebrate life cycle |
|
Definition
1. meiosis
2. zygote formation
3. mitosis
4. blastula development
early gastrula development ( cells bending into organisms and creating digestive tract)
6.future mesoderm forms
7. Endoderm and digestive tract develop
8. larva form develops
9. metamorphosis into adult form |
|
|
Term
| protostomes and deuterostomes |
|
Definition
| organisms who develop mouth first are protostomes. those who develop their anus first are deuterostomes |
|
|
Term
|
Definition
| organisms which have no body cavity |
|
|
Term
|
Definition
| organisms which have a slight body cavity ( a cavity lined with mesoderm and endoderm tissue |
|
|
Term
|
Definition
| organism with a true cavity, must have a cavity lined by all mesoderm tissue to be considered true |
|
|
Term
|
Definition
| a common ancestor and everything in an evolutionary line which comes after it |
|
|
Term
|
Definition
1.asymmetrical bodies
2.lack true tissues
3. Sessile ( move only through reproduction)
4. sack like bodies with pores
5. suspension feeders ( use choanocytes to pull in food from water) |
|
|
Term
|
Definition
1. cnidocte ( a structure which gives them the ability to sting)
2. have true tissues ( ecto and endoderm)
3. Radial symmetry
4. 2 types of body, medusa or hydra
5. gastrovascular cavity which acts as the means for digestion and circulation of nutrients |
|
|
Term
|
Definition
1. part of family of platyhelminthes
2. bilateral symmetry
3. no body cavity
4. dorsoventrally flattened
5. 3 laters triploblastic
6. gastrovascular cavity ( not all flatworms have one such as tapeworms) |
|
|
Term
|
Definition
1. have circular muscles
2. psuedocoelom
3. covered by a cuticle
4. have a complete digestive tract |
|
|
Term
|
Definition
1.aquatic or terrestrial environments
2. have a muscular foot which allows for movement
3. have a mantle which produces shell and encloses visceral mass
4. circulatory system
5. Some have radula which helps them scrape food off of surfaces |
|
|
Term
|
Definition
1. ringed worms
2. closed circulatory system
3. circular and longetudal muscles which allow for movement in all directions |
|
|
Term
|
Definition
1. spiny skined
2. have endo skeleton
3. radial symmetry as adults
4. water vascular system with tube feet ( create suction by varying pressure)
5. deuterostomes |
|
|
Term

|
Term
| trace the plant evolutionary tree |
|
Definition
| ancestor- Non Vascular plants (mosses) -- Vascular tissue( ferns)-- seed production-- Gymnosperms- Angiosperms ( flower and fruit). |
|
|
Term
| trace the invertibrate evolutionary tree |
