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
