angiosperms and gymnosperms

apical meristem

Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.

xylem

vascular tissue that carries water upward from the roots to every part of a plant; conducts water from roots to shoots

collenchyma

gives flexible strength (celery string like)

parenchyma

fundamental tissue of any organ or system, most of the plant is made of this

found in regions of increase in diameter/girth of a plant

which generation in the life cycle produces spores?

the sporophyte generation

what is a characteristic unique to seed producing plants along with seeds?

pollen

what is the yellow dust on the cars during the spring?

pine pollen; it is so abundant because the pines are wind-pollenated

double internal fertilization

what is a similarity between fungi and arthopods?

both groups use chitin for support

what are the filamentous mats formed by most fungi called

hyphae

When pathogenic fungi are found growing on the roots of grape vines, grape farmers sometimes respond by covering the ground around their vines with plastic sheeting and pumping a gaseous fungicide into the soil. The most important concern of grape farmers who engage in this practice should be that the _____.

fungi might also kill mycorrihizae

a digestive system with a single opening

Platyhelminthes

flatworms, triploblastic

Cnidaria

jellyfish, diploblastic

mollusca

(snails, clams, squids, octopuses) have a soft body that in many species is protected by a hard shell;triploblastic

echinodermata

radially symmetrical marine invertebrates including e.g. starfish and sea urchins and sea cucumbers;triploblastic

arthropada

paired, jointed appendages and exoskeletons, use gills, lungs, trachae for gas exchange, open circ system, complex nervous system;triploblastic

poriferia

the phylum of sponges;neither triplo or diplobstic

nematoda

Phylum of roundworms;triplo

protosomes

blastopore becomes mouth

deuterosomes

anus develops first

diploblasts make all of the germ layers except the

1)ectoderm

2)endoderm

3)mesoderm

mesoderm

parts of the flower

stigma, style, ovary, sepal, stem, anther, filament

stigma flower

The tip of the female reproductive structure of a flower where the pollen lands

style

The stalk of a flower's carpel, with the ovary at the base and the stigma at the top.

stamen

the male reproductive organ of a flower

sepal

A modified leaf in angiosperms that helps enclose and protect a flower bud before it opens.

the stage of hte fungus life cycle in which cytoplasm is fuesd but the two nuclei are unfused is the ____ stage

heterokaryotic

the process by which two nuclei fuse is known as

kayogamy

excretory

removes waste

digestive

food processing

integumentary

protection from mechanical injury, infection and dehydration, involved in thermoregulation

skeletal

body support, protection of internal organisms

what is the change in allele frequency in a population over time

microevolution

an event in which a size of a population is reduced randomly, rapidly, and drastically is known as

the bottleneck effect

mechanical isolation

Morphological differences can prevent successful mating

gametic isolation

Sperm of one species may not be able to fertilize eggs of another species

hybrid breakdown

Some first-generation hybrids are fertile, but when they mate with another species or with either parent species, offspring of the next generation are feeble or sterile

temporal isolation

organisms are active or receptive to reproductive activity at different times

habitat isolation

Two species encounter each other rarely, or not at all, because they occupy different habitats, even though not isolated by physical barriers

autopolyploidy

an individual that has more than two chromosome sets that are all derived from a single species

darwin

English natural scientist who formulated a theory of evolution by natural selection (1809-1882)

lyell

'Father of uniformitarianism' - belief that the earth was old, and catastrophism happened slowly

lamarack

Inheritance of acquired traits; before Darwin. People believed him more than Darwin.

Linnaeus

sought to classify all living things using a binomial naming system

Malthus

an English economist and demographer; all biological populations have a potential for increase that exceeds the actual rate of increase, and the resources for the support of increase are limited

artfical selection occurs when

humans selectively breed individuals to reflect desired traits
