Exam 2 Flashcards
Baccili
rod-shaped
Cocci
spherical/round-shaped
Spirochete
spiral/zigzag
gram-positive
- purple
- high peptidoglycan in the cell wall means the stain attaches more
gram-negative
-pink
- little to no peptidoglycan
antheridia
male gamete that forms sperm
archegonia
female gamete that forms a single egg
what are the derived characteristics of land plants
- cells walls made of cellulose
- chlorophyll a and b in plastids
-use starch as a storage product - embryophytes
- waxy cuticle to prevent from drying out
- stomata allow gas exchange through the cuticle
what is endosymbiosis
- how eukaryotes evolved
- certain organelles arose from symbiotic relationships between large cells and bacteria incorporated to live with them
- one organism lives inside the other
haploid
-one set of chromosomes
- meiosis
diploid
- 2 sets of chromosomes
- mitosis
microsporangia
- produce microspores that give rise to male gametophytes when they germinate
megasporangia
- produce megaspores that develop into female gametophytes
characteristics of monocots
- long leaves that have parallel veins
- flowers sprout in multiples of 3
- seeds have one cotyledon
- in the stem vascular tissue is scattered
- roots are fibrous( no main root)
- endosperm is present in the mature seed
characteristics of eudicots
- seeds have 2 cotyledons
- veins in leaves are netlike
- in the stem, the vascular tissue is arranged in a ring
- root system has a taproot(main root)
- flowers sprout in multiples of 4 or 5
- endosperm is absent in mature seeds
what are examples of monocot plants
orchids, lilies, palms
derived characters in seed plants
- sporophyte generation is the dominant stage
- heterosporous
-have vascular tissues
examples of protists
paramecium, stentor, amoeba
what are examples of eudicot plants
roses, cacti, sunflowers
human uses of seed plants
wood for shelter, medicines, cotton for clothing, most food,
what are 3 types of angiosperms (phylum Anthophyta)
magnoliid, eudicot, monocot
gymnosperms
seeds that are exposed or borne on scales of cones
angiosperms
flowering plants that produce seeds within a mature ovary(fruit)
what is flagella
hair-like structures that prokaryotes use to move to an environment that better suits them, adhere to surfaces, and sense wetness
what is a pseudopodia
cytoplasmic extensions that emerge temporarily in a eukaryotic organism
what are cilia
short eyelash filament to move water relative to the cell in a regular cilia movement.

explain why kingdom protist is no longer a valid kingdom
because it contains groups that have ancestors in common with other groups.
explain mutualism
both partners benefit
explain commensalism
one partner benefits and the other remains neutral and not helped or harmed
explain parasitism
one partner lives on or in one another while the parasite benefits and the host is harmed
list some characteristics of archae
- unicellular, prokaryotes
- ## dont have peptidoglycan
what are examples of archaea
Thermophiles.
Acidophiles.
Methanogens
f factor and conjugation
f factor is required for conjugation
its the fetility factor
allows the donor to produce a thin, tubelike structure called a pilus, which the donor uses to contact the recipient.
