Biology unit 1: Flashcards
(57 cards)
Describe a monocot
fibrous roots, one cotyledon(seed leaf), parallel leaves, in flower parts/petals of 3s. scattered vascular bundle
what is the specialized stem that stores food
tuber
Describe a dicot
in flower parts of 4-5s, taproot(single large root), 2 cotyledons(2 seed leaves), veiny like leaves , ring like vascular bundle.
plants are ? (characteristics)
multicellular eukaryotes , containing chloroplast for photosynthesis
how much photosynthesis occurs in the ocean?
70%
what vessel carries water and is it an alive or dead cell
The xylem carries water and minerals up the stem, it is made of dead cells.
What vessel carries sugars up the stem, and is it alive or a dead cell
Phloem, carries sugar up and down the stem depending on which part needs it more, it has cells that are alive
Describe non-vascular plants
They have no system of vessels, examples are moss. Need a moist surface to swim for reproduction and use spores.
for non-vascular cells what term is used for moving nutrients and water between cells?
osmosis and diffusion
what was the first vascular plant and do they use seeds or spores?
It was ferns and they still use spores to this day
what are “naked seeds” called, name one example.
They are called gymnosperms, any species of pine trees works
What was the most recent evolution for plants to reproduce and explain the actions.
It was angiosperms, they produce flowers that attracts animals, the seeds are in the fruit, attracting animals to spread them.
Draw the diagram of a flower
Are mono and dicots angiosperms or gymnosperms.
They are angiosperms.
One example of a soft stemmed/herbaceous monocot and a woody/hard stemmed monocot.
Bamboo is the hard stemmed monocot while, grass would be a soft stemmed one.
One example of a herbaceous/soft stemmed dicot and a woody/hard stemed one
Potatoes would be a soft/herbaceous stemmed monocot while, oak would be a woody hard stemmed one.
draw a dicot vascular bundle
Correct answer should be vascular bundles in a ring
draw a monocot vascular bundle
all scattered vascular bundles
draw a monocot root system
It should be fibrous and be all scattered about
Draw a dicot root system
Taproot, should have branches but one main root
draw the phylogeny/evolution relation of plants
What is the function of rhizomes?
underground stem buds for reproduction, grows shoots and roots, also cloning the parent plant.(Stays on the parent plant). They growing horizontally
Function of stolon’s?
A stem that grows upwards and grows into new plants at the tip.
draw the structure of a root
