Unit B Section 1-4

Front 1

Section 1.1:

what are the three parts of a seed which comes from a seed plant?

Back 1

the outer layer (seed coat), the embryo, or baby plant which is on the inside, and the cotyledon.

Front 2

Section 1.1:

what are the 6 parts of a plant?

Back 2

flower, stems, seeds, leaves, cones, roots.

Front 3

Section 1.2:

what are 3 processes for moving water up the stems from the roots? define them.

Back 3

transpiration (plants sweating) capillary action (water traveliong up the roots through tiny stems and when water particles are attracted to each other or stick together) and osmosis (in cells, the movement of water against the cell membrane).

Front 4

Section 1.2:

what is a process that plants use to make food and what is the equation for it?

Back 4

photosynthesis, and chloroplasts (the structure in the plant that carries out photosynthesis), and the equation is solar energy + carbon dioxide + water = food and oxygen.

Front 5

Section 1.2:

what does this represent?

Back 5

osmosis

Front 6

Section 1.2:

what is a process that plants use to use food? what is its equation? define it.

Back 6

Cellular respiration- the process in which cells break down sugar particles into carbon dioxide, water and energy.

equation: food + oxygen + water = energy and carbon dioxide and water.

Front 7

Section 1.3:

what are the two ways for plant reproduction?

Back 7

sexual reproduction (seeds to make new plants) and vegetative reproduction (no seeds)

Front 8

section 1.3

what are the reproductive parts of a flower?

Back 8

stigma, ovary and anther, filament

Front 9

section 1.3:

what are the steps that occur in pollination?

Back 9

1. pollen lands on pistil

2. pollen grains travel down the style to the ovary

3. each ovule in the ovary contains an egg. sperm fertilizes it.

4. the fertilized seed becomes an embryo and forms a seed.

Front 10

Section 1.3:

what is the plant cycle?

Back 10

seeds-stage 1is the embryo, stage 2 is stored food, stage 3 is the seed coat. seedling stage- produces leaves and can produce its own food. adult stage- produces reproductive structures.

Front 11

1.5

plants need the right amount of:

Back 11

light, water, nutrients, space

Front 12

1.5

what are the 5 key nutrients a plant needs? what happens if there is a lack of nitrogen?

Back 12

nitrogen, phosphorus, potassium, calcium, magnesium. lack of nitrogen leads to yellow leaves.

Front 13

section 2

what do plants do in the environment?

Back 13

they provide oxygen, provide shelter, provide food, polants build and protect soil, plants are crucial for the food chain.

Front 14

section 2.3

l what are living, non living and non sustainable resources?

Back 14

living resources are those living things that humans need to meet their basic needs. non sustainable resources are those things that we are using more quickly then they are being replaced.

Front 15

section 4;

what is a yield?

Back 15

the amount of useful plant material produced per crop or per sectioned crop. ex. California has a higher yield or oranges then Canada.

Front 16

section4;

what are 3 ways for yields?

Back 16

shelter and green house, hydroponic systems and fertilizer.

Front 17

what is this?

Back 17

artificial environment

Front 18

what is a species, variety and traits?

Back 18

a species is living things of the same kind that are able to reproduce, a variety is a group of organisms of the same specifies that have specific characteristics that can distinguish it from other variety's of species. a trait is a characteristic for those organisms.

Front 19

what is selective breeding/

Back 19

a technology for producing new variety's of an organism that involves choosing parents with desired traits in order to produce an offspring with these traits.

Front 20

what is genetic engineering?

Back 20

a process in which single genes are added to a plants genetic material.

Front 21

what are herbicides and pesticides?

Back 21

they are things that kill harmful insects and plants.

Front 22

what is biological control?

Back 22

a process which natural predators of the pests are introduced to an area where the pest thrives.

Front 23

what is mono culture and biodiversity?

Back 23

mono culture is when each planted field is used to produce plant growth. biodiversity is when ther4e is a number of different species in an environment.
