Exam 3 Review-Bio Final
Endosperm tissue
3n
The term heterospory means
A plant produces two types of spores that produce the different gametophytes (male and female)
Apples are formed from the floral tube of the tree on which they are born. The type of fruit that is formed from other plant tissues in addition to the ovary are called
Accessory fruits
Plants have a distinct haploid and diploid stage. This is known as
Alternation of generations
Which of the following would not be part of a mature seed?
An embryonic gametophyte
What is the main difference between gymnosperms and angiosperm
Angiosperms produce seeds that are contained within an ovary wall
Hornworts would belong to this phylum
Anthocerophyta
These alveolates are characterized as spore-forming parasites that cause serious disease in humans. The organisms have unpigmented chloroplasts and an apical complex that they use to attach to their host. plasmodium, the causative agent of malaria is an example of this group
Apicomplexans
Red algae, green algae, and all land plants are placed into this group because all derived their chloroplast through primary endosymbiosis
Archeplastids
Which statement about gymnosperm and angiosperm is false
Both groups have free-living gametophytes
This group of bacteria lack peptidoglycan in their cell walls. They are typically described as energy parasites, depending on the host's ATP to survive
Chlamydias
These unikonts are hypothesized to be the closest living non-animal relatives of animals. Their bodies are composed of cells bearing a single flagellum surrounded by a collar of microvilli that trap food
Choanoflagellates
Some protist consist of a single cell with multiple nuclei. This condition is known as
Coenocytic
Which of the following would not be a common shape associated with bacterial cells
Coenocytic
This group of excavates is characterized by possessing one or two nuclei, no functional mitochondria, no golgi bodies, and up to eight flagella. An example of this group would be giardia intestinals, a water-borne protist that causes diarrhea
Diplomonads
What type of fruit would contain a single hard stone (pit) surrounded by a freshy fruit?
Drupe
Which group of protobacteria would be characterized as a small group of bacteria that inhabit the digestive tract? An example of this group would be helicobacter pylori, the causative agents of ulcers
Epsilon
Liverworts can reproduce asexually using tiny packets of cells called
Gemmae
Which of the phyla would contain ephedra, a plant that produces compounds that simulate the heart and increase blood pressure
Gnetophyta
Perfect flowers
Have both carpels and stamen
These members of phylum pteriodophyta have true roots, smalls leaves, and hollow sterns that often contain silica. Two forms of shoots are produced, vegetative with leaves and reproductive with cone-shaped strobuli
Horsetails
What is the purpose of the waxy cuticle in plants
It prevents dessication
Which is a differentiating characteristic of land plants from green algae
Land plants have a waxy cuticle
Which Eukaryotic organelles liley arose from the symbiotic relationship between larger cells and bacteria
Mitochondria and Chloroplast
You find a flowering plant that produces flexible, herbaceous stems and flowers with three petals. You split open a seed and find that the developing embryo has one cotyledon and that the seed is full of endosperm. Which class would this plant belong to
Monocatyledones
Most conifers have seperate male and female reproductive parts of the same tree. This condition is referred to as
Monoecious
Which of the following statements about Bryophytes is false
Mosses have a dominant sporophyte generation
What are the small circles of DNA that exist within the bacterial cytoplasm in addition to the bacterial chromosome
Plasmids
Each angiosperm pollen grain produces two cells, once of which may develop into
Pollen Tube
Which structure would represent the gametophyte generations in ferns
Prothallus
Within ciliates, what do the micronuclei control
Reproduction
You are doing a study of a newly found protist. When you examine the chloroplasts inside of the organism, you discover that it has four membranes. This would indicate that it was formed as a result of
Secondary endosymbiosis
The diploid portion of the plant life cycle is known as the
Sporophyte generation
Which of the following parts of the flower would be responsible for the production of ovules?
Stamen
Strawberries reproduce asexually using these above ground horizontal sterns also called runners
Stolons
Some bacteria avoid being phagocytized by a host's immune system by means of
Their capsule or slime layer
Why are mosses and liverworts limited in size
They lack vascular tissue
Bacterial cells that are gram positive would contain a ___ layer of ___ in their cell walls
Thick; peptidoglycan
What is the purpose of sex pili
To transmit DNA between bacteria
Which of the following is not a way in which bacteria reproduce
Transformation
You find find a bunch of flowers that are very small and lack any showy colorization.The flowers produce no odor, but produce a large amount of pollen when you shake them. What is the likely mode of pollen transport for this plant
Wind *****
When angiosperms microsprocytes undergo meiosis, the results is
four haploid microspores
How would a chemoautotroph use for an energy source
inorganic compounds
At maturity, the female gametophyte in angiosperms contains
megaspocyte hoe
This group of stramenopiles were once classified as fungi. Their bodies are composed of coenocytic hyphae that digest organic matter. Phytophthora infestans, the causative agent of potato blight lead to the Irish potato famine
water molds
