Biology CIA 4
Where did the first plants evolve from?
green algae
What part of the plant does photosynthesis take place?
leaf
Which part of the plant does photosynthesis take place? - Leaves
leaves
Stamen
male reproudcitve part of flower
What are the two main types of flowering plants based on seed types?
monocots and dicots
Mosses and liverworts absorb water from the soil by the process of what?
osmosis
food chain
series of steps in an ecosystem in which organisms transfer energy by eating and being eaten
The functions of plant stems include providing support, transporting water and materials, and
storing food and water
What is the source of all energy in a food chain?
sunlight
Anther
the part of a stamen that contains the pollen.
Sepal
A modified leaf in angiosperms that helps enclose and protect a flower bud before it opens.
gravitropism
A root growing downward and a shoot growing upward are both examples of
succession
A series of predictable and orderly changes within an ecosystem over time.
ovule
A structure that contains an egg cell
secondary succession
Succession following a disturbance that destroys a community without destroying the soil
Pistil
The female reproductive part of a flower
Plants' response to water or moisture
Hydrotropism
Photosynthesis equation
6CO2 + 6H2O + light energy --> C6H12O6 + 6O2
ovary
A flower structure that encloses and protects ovules and seeds as they develop.
phototropism
A growth response to light
thigmotropism
A growth response to touch
primary succession
An ecological succession that begins in an area where no biotic community previously existed
Which food chain correctly describes the flow of energy in an ecosystem?
Grass-->cow-->human
What is a tree ring and describe what would happen if a drought occurred.
It shows the age of the tree and if a drought occurred the rings would be closer. If the rings are closer, this means the tree is dying.
green algae and plants
Photosynthetic, multi-cellular, producers. They don't both have leaves and stems.
stigma (flower)
The tip of the female reproductive structure of a flower where the pollen lands
Which flowering plant completes its life cycle within 1 year? - Annual
annual
Osmosis
diffusion of water across a selectively permeable membrane
what plants are seedless?
ferns
