Reproduction of flowering plants

Question 1

Area inside an ovary where an egg & two polar nuclei are found. The site of fertilization within a flower.

Answer 1

Ovule

Question 2

Nucleus within a pollen grain that forms the pollen tube in a flower.

Answer 2

Tube nucleus

Question 3

Nucleus within a pollen grain that produces two sperm nuclei or sperm.

Answer 3

Generative nucleus

Question 4

Hollow tube leading from the stigma to an ovule within the ovary of a flower.

Answer 4

pollen tube

Question 5

Two haploid (n) structures within the center of an ovule.

Answer 5

Polar nuclei

Question 6

A fertilized egg. Diplod (2n) structure

Answer 6

Zygote

Question 7

Structure formed from the ovule of a flower. It contains the zygote (developing plant) & endosperm.

Answer 7

Seed

Question 8

Triploid (3n) structure formed when a sperm nucleus fuses with the two polar nuclei within an ovule. It is a food source in a seed for developing plant embryo

Answer 8

Endosperm

Question 9

surrounds & helps to protect developing seeds

Answer 9

Fruit

Question 10

What are the (6) modes of asexual reproduction

Answer 10

1) Budding
2) Binary Fission
3) Spore production
4)Fragmentation
5)Parthenogenesis
6) Vegetative reproduction

Question 11

Budding

Answer 11

Reproduction where an outgrowth occurs on an organism that later breaks off & grows into an entire organism.

Question 12

Binary Fission

Answer 12

Reproduction where mitosis divides DNA in an organism. The organism than splits to create 2 new organisms.

Question 13

Spore production

Answer 13

Reproduction where mitotic cell divisions create a series of spores that grow into new organisms.

Question 14

Fragmentation

Answer 14

Reproduction where a portion of an organism breaks off. The broken piece can grow into a full organism.

Question 15

Parthenogenesis

Answer 15

Reproduction where an organism produces haploid (n) unfertilized eggs that grow into adults
