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
