The Biosphere

100

What are the four main spheres of the Earth

Atmosphere, Hydrosphere, Geosphere, Biosphere

200

What is a biome? What is an example

A large community of life with similar environmental and biological characteristics

300

What are three reasons soil is important?

1/4 of life is found in the soil

Provides nutrients to plants

Filters water

Biosphere couldnt exist without it.

400

What are the three types of soil?

Clay 

Sand 

Silt

500

What is soil made of?

Eroded rock particles

Water

Air

Organic Matter

Plants

100

What is the difference between vascular and nonvascular plants?

Vascular: Tubes to transport water and resources

Nonvascular: No tubes to transport water and resources

200

This brings water and nutrients from the roots to the plant

Xylem

300

This carries food from the leaves to the plants:

Phloem

400

Plants are these three things and have this one important thing:

Are eukaryotic

Are multicellular

Are autotrophs

Have cell walls

500

What are the five things plants need?

Soil 

Air

Water

Sun

Space

Plant Reproduction

100

Ferns , horsetails, and club moss reproduce through what?

Spores

200

What are the two types of seed plants

Gymnosperms 

Angiosperms

300

How do angiosperms feed themselves before photosynthesis begins

Through the food stored in the cotyledons

400

Explain how gymnosperms reproduce?

Female cones open their scales and pollen blown by the wind sticks to them. The cone closes and then produces a seed over two years.

500

What is the male part of the plant

What are the female parts of the plant

What is the substance needed for flower reproduction?

Male part: Stamen (anthers)

Female Part: Pistil (Stigma, style) Ovary

Pollen is needed for flower reproduction

Plants Part 2

100

What is the main difference between a monocot and dicot

Monocots have one cotyledon while dicots have two.

200

What are the two things leaves do?

use sunlight for photosynthesis to make food

Lets CO2 in and water vapour and oxygen out.

300

What are the three things roots do?

Absorb water and minerals from the soil

Anchor the plant in the soil

Store extra food that the plant makes during photosynthesis

400

What is the cell that creates energy through photosynthesis

Chloroplast

500

What are the three tropisms we learned about? What do they do?

Gravitropism- plant growth in response to gravity

Phototropism- plant growth in response to light

Thigmotropism- plant growth in response to touch
