embryo seed coat cotyledon
What happens in the classification system as you move down from the top to bottom?
as you move down the list you are let with a group of all the same types of organisms.
Why do scientists use Latin and Greek terms to name organisms?
Scientist want to use one universal language that everyone can understand
What is the function of the seed coat?
this is what protects the seed from harsh weather
What is the function of the embryo?
this is what houses the roots stems and leaves are located.
What is the function of the cotyledon?
this is in the seed and it provides the energy for germination
Name another part of the seed and it's function besides the cotyledon, seed coat and embryo?
the epicotyl (shoot)
Name at least 4 ways a seed can pollinate.
The wind, the rain, by an insect flying from flower to flower and gravity
What does an imperfect flower have?
A flower which has only a male OR a female reproductive structure
What does a perfect flower have?

usually have a tap root system
What do the roots of a monocot plant look like?
usually have a fibrous root system
What does the stem of a dicot plant look like?
bundles of vascular tissue arranged in a ring
What does the stem of a monocot plant look like?
bundles of vascular tissue usually scattered throughout the stem
What do the leaves of a dicot plant look like?
veins are usually netlike or branched
What do the leaves of a monocot plant look like?
veins are usually parallel
What does the flower of a dicot plant look like?
flowers usually in multiples of 4 or 5
What does the flower of a monocot plant look like?
flowers usually in multiples of 3
What does the growth of a monocot plant look like?
1 cotyledon, stays below ground
What does the growth of a dicot plant look like?
2 cotyledons, emerges from ground while sprouting
How are organisms classified?
according to their structure, it is a 7 layer system, similarities between organisms increase as you move down the triangle.
Be able to list a part of the flower and tell what it's function is, for example: What is the function of the anther?
This produces and stores the pollen
What are the 2 parts of a scientific name? Which of the two are more general?
Genus and species and genus is more general, speicies is more specific.
Why is a WOW bug considered a parasite?
WOW bugs live off of bee larvae, they suck nutrients from the larvae until it dies.
Name 3 unique characteristics of blackworms?
150 -250 body segments, even a small piece of blackwork can be regenerated, it has a special rapid escape reflex
Name 3 unique characteristics of earthworms?
helps to make the soil fertile, it can regenerate when cut into 2 if it has its clitellum, up to 25 cm long
How does a blackworm reproduce?
Name the seven levels of the Linneaus System of Classification.
K________, P ____________, C _________, O___________, F_________, G_________, S__________
What happens in the classification system as you move down from the top to the bottom?
it divides all living things into hierarchical groups based on their characteristics, as you move down the list you are left with a group of all the same type of organism (namely, a species).
Most insects have 3 distinct body parts, what are they?
the head, thorax, and abdomen
What does asexual mean?
an organism that needs only one parent to reproduce
What do blackworms and earthworms have in common?
they have no legs, they have segmented bodies, they both have seta (hair that helps them move) and both can regenerate, same genus.
What do seeds need to survive?
water, suitable climate, good soil, nutrients and light.
What is a binomial nomenclature
the two-part method of naming organisms shown as the Genus and species - an organism's scientific name
What is the life cycle of a plant? You will need to define each part.
germination, pollination, fertilization, and dispersal
What is germination?
When a seed is placed in the right conditions so that it begins to grow.
What is pollination?
When pollen from a flower's anther is transferred to either the same plant's stigma (self-pollination) or another plant's stigma (cross-pollination)
What is fertilization (of flowers)?
When there is pollen on the stigma, a tube cell from the pollen forms a pollen tube and sperm cells travel to the ovary and combine with egg cells
What is dispersal?
After an ovule is fertilized, the flower withers, and the ovary develops into a fruit. The fruit helps protect the seeds and the seeds get dispersed when the fruit falls from the plant or is eaten (and then excreted) by animals.
