Q

Define cellulose

A

Material composing plant cell walls

2
Q

Define cuticle

A

Waxy coating on plant surfaces that prevents water loss

Q

Define autotroph

A

An organism that produces its own energy/food

4
Q

Define chloroplast

A

Membrane that contains pigments vital for photosynthesis

5
Q

Define stomata

A

Openings on leaf that allow for gas exchange and cooling mechanism

Q

Define chlorophyll

A

Green pigment needed for photosynthesis

Q

Define stroma

A

Fluid filled region containing enzymes vital for photosynthesis

Q

Define tap root

A

Deep root system that accesses ground water

9
Q

Define Meristem

A

Undifferentiated tissues in plant growth zones

10
Q

Define Node

A

Area from which leaves, branches, and aerial roots emerge

11
Q

Define Petiole

A

Stalk attaching leaf to stem

12
Q

Define axillary bud

A

Lateral bud that may grow into a branch of flower cluster

13
Q

Define internode

A

Interval between nodes along a stem

14
Q

Define monocot

A

Plants with one seed leaf

15
Q

Define eudicot

A

Plants with 2 seed leaves

16
Q

Define bryophytes and name the 3 families

A

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

17
Q

Define angiosperm

A

Seed bearing plant with an enclosed seed/flowering plant

18
Q

Define gymnosperm

A

Seed bearing plant with a naked seed

19
Q

Define cotyledon

A

Seed leaf that nourishes/protects the embryo

20
Q

Define sepal

A

Outermost part of a flower that encloses the bud for protection

21
Q

Define filament

A

Stalk supporting anther

22
Q

Define anther

A

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

23
Q

Define ovule

A

Plant structure that develops into a seed when fertilized

24
Q

Define style

A

Stalk connecting the stigma and the ovary

25
Q

Define stigma

A

Receptive tip of pistil (may be several fused together)

26
Q

Define ovary

A

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

27
Q

What is the purpose of photosynthesis

A

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

28
Q

What inputs are needed for photosynthesis?

A

Sunlight and CO2

29
Q

What is created by photosynthesis?

A

Oxygen and carbohydrates

30
Q

Why is oxygen created through photosynthesis?

A

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

31
Q

What is the pigment that absorbs light during photosynthesis?

A

Chlorophyll

32
Q

What type of cell contains the chlorophyll pigment?

A

Plant organelles called chloroplasts

33
Q

Briefly identify the main purpose of the 2 stages of photosynthesis

A

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

34
Q

What is the purpose of the C4 and CAM pathways?

A

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
