Question 16

Define bryophytes and name the 3 families

Answer 16

Non-vascular land plants (liverworts, hornworts, and mosses)

Question 17

Define angiosperm

Answer 17

Seed bearing plant with an enclosed seed/flowering plant

Question 18

Define gymnosperm

Answer 18

Seed bearing plant with a naked seed

Question 19

Define cotyledon

Answer 19

Seed leaf that nourishes/protects the embryo

Question 20

Define sepal

Answer 20

Outermost part of a flower that encloses the bud for protection

Question 21

Define filament

Answer 21

Stalk supporting anther

Question 22

Define anther

Answer 22

Terminal part of stamen where pollen matures (usually has 2 lobes)

Question 23

Define ovule

Answer 23

Plant structure that develops into a seed when fertilized

Question 24

Define style

Answer 24

Stalk connecting the stigma and the ovary

Question 25

Define stigma

Answer 25

Receptive tip of pistil (may be several fused together)

Question 26

Define ovary

Answer 26

Femal reproductive organ that holds the ovule, may be above or below the point connecting the sepals and petals

Question 27

What is the purpose of photosynthesis

Answer 27

To turn sunlight and CO2 into oxygen and sugar (product food/energy for plant)

Question 28

What inputs are needed for photosynthesis?

Answer 28

Sunlight and CO2

Question 29

What is created by photosynthesis?

Answer 29

Oxygen and carbohydrates

Question 30

Why is oxygen created through photosynthesis?

Answer 30

It is released as a by product. It is also used in cellular respiration to break down glucose.

Question 31

What is the pigment that absorbs light during photosynthesis?

Answer 31

Chlorophyll

Question 32

What type of cell contains the chlorophyll pigment?

Answer 32

Plant organelles called chloroplasts

Question 33

Briefly identify the main purpose of the 2 stages of photosynthesis

Answer 33

The purpose of stage one is to product ATP & NADPH, needed in Calvin cycles The purpose of stage two is to fix carbon to produce carbohydrates

Question 34

What is the purpose of the C4 and CAM pathways?

Answer 34

The purpose of c4 is to bypass photo respiration (which wastes energy) The purpose of CAM is to prevent water loss by keeping the stomata closed during the day and absorbing CO2 at night
