Meiosis in plants-Ch2-P35-37

Question 1

What are the two distinct generations (stages) of a plant’s life cycle?

Answer 1

The two stages alternate.

1. Diploid sporophyte - produces haploid spores through meiosis.
2. Haploid gametophyte - produces haploid gametes through mitosis.

Question 2

What is the plant life cycle two generations sometimes called?

Answer 2

alternation of generations

Question 3

In the plant life cycle the immediate products of meiosis are called? Then when they undergo one or more mitotic divisions what are they called?

Answer 3

spores, not gametes at first after meiosis.

Then called gametes after mitosis.

Question 4

Answer 4

reduction, haploid

Question 5

In flowering plants the sporophyte is?

Answer 5

the obvious vegetative part of the plant

Question 6

In flowering plants the gametophyte consists of how many haploid cells within the sporophyte?

Answer 6

A few

Question 7

The flower which is the sporophyte contains the

Answer 7

reproductive structures. In some plants the male and female reproductive structures are found in the same flower while in other plants they exist in different flowers.

Question 8

The male part of the flower is called the?

Answer 8

stamen

Question 9

The stamen contains?

Answer 9

diploid reproductive cells called microsporocytes each of which undergoes meiosis to produce four haploid microspores.

Question 10

Explain how diploid reproductive cells (microsporocytes) from the stamen undergo meiosis to produce four haploid microspores?

Answer 10

Each micr
