Q

What do Pollen grains do?

A

THey are desiccation resistant, they consist of microgametophytes which caryy the male gametes of seed plants

Q

What happens in the pollen tube?

A

Embryonic sporophyte within the gametophyte tissues that are protected by previous sporophyte generation.

Q

In the alternation of generation of a Gymnosperm is the sporophyte large or the gametophyte?

A

The sporophyte is larger and longer lived. The gametophyte is tiny and depends on sporophyte for nutrition

Q

What dose the MALE part of a flower contain?

A

Fillament + Anther= Stamen

17
Q

What does the FEMALE part of a flower contain?

A

Ovary+ Style+ Stigma= Carpel/Pistil

18
Q

What is a Pedicel? (Angiosperm)

A

Stalk that supports the flower

19
Q

What is the Receptacle? (Angiosperm)

A

tip of the pedicel where the flower parts attatch

20
Q

What is the Sepal?

A

outer green, brown or colored that look like petals. They also protect the petals they are sometimes small and below the petals.

21
Q

What is a petal?

A

Colored, white, or even greenish whorl of bracts located just inside the sepals

22
Q

What is a Perianth?

A

It’s the Sepals+Petals together

23
Q

What does the Endosperm do?

A

It forms a nutritive tissue in the seed

24
Q

Where does the life cycle take place in an angiosperm?

A

It takes place in the Ovary of the Carpel of a flower

25
Q

How does the double fertilization occur?

A

Three sperm are produced, one fuses with one egg the other two fuse with the polar bodies which form the endosperm

26
Q

Angiosperms provide what percent of human calories?

A

80%

27
Q

What do Angiosperm provide?

A

Food- Potatoes, Mais, rice, wheat
Beverages- coffee, tea
Warm fire
Aspirin- made from a tree

28
Q

What are some pollinators we discussed in class?

A

Bats, BIrds, bees, moths, wind

29
Q

Pollinators: Sepals and petals are reduced or not at all present; feathery or relatively large stigma; flower no odor, what’s the pollinator?

A

WIND

30
Q

Sepals and/or petals Large, white or subdued (greenish or burgundy); distinct odor: Odor STRONG, HEAVY, SWEET (usually at night they give out the sweet scent)

A

MOTH

31
Q

Sepals and/or petals Large, white or subdued (greenish or burgundy); distinct odor: Odor STRONG, FERMENTING or FRUITLIKE; flower parts and pedicel STRONG (nucturnal flowers) what’s the pollinator?

A

Sepals and/or petals Large, white or subdued (greenish or burgundy); distinct odor: Odor of SWEAT, FECES, or DECAYING meat. What’s the pollinator?

A

FLY

33
Q

Sepals and/or petals Colored; odor may or may not be present.
-Flower shape is irregular; sepals or petals blue, yellow, or orange; petal adapted to serve as a “landing platform”
may have dark lines on petals; SWEET, FRAGRANT odor.
what’s the pollinator?

A
