1
Q

Alternation of generations

A

Happens in every plant, but depends on type of group.

2
Q

Alternation of generations cycle

A

Sporophyte-Meiosis-Spores-Mitosis (split)- Gametes (egg or sperm)-Fertilization- Zygote-Mitosis

3
Q

Examples of Vegetative Reproduction

A
Stolon/Rhizome 
Bulbs, tubers, corms 
Adventitious roots 
Sucks
Plantlets
4
Q

Apomixis

A

Seeds produced without fertilization

5
Q

Asexual Reproduction Advantages

A

efficient, if environment doesn’t change

6
Q

Asexual Reproduction Disadvantages

A

Clones of you, will also have diseases

7
Q

Meiosis

A

unclear division that halves the chromosome number or the haploid number df chromosomes. (2n=n) (4n=2n)

8
Q

Fertilization

A

fusion of haploid gametes that produces a diploid zygote

9
Q

Sperm

A

cheap

10
Q

Egg

A

expensive

11
Q

Seedless Plants

A

Water is required, sperm swim

12
Q

Seed Plants (Gymnosperms)

A

Use wind pollination hold on to embryo and nutrients

13
Q

Angiosperms

A

flowers,seeds,fruit

14
Q

Flower

A

produces gametes and develops seeds and fruit

15
Q

Seed

A

consists of embryo ad nutrient stores

16
Q

Fruit

A

develops from the flower and contains the seeds

17
Q

Structure of flower

A

Pistal, Stamen, Stigma, anther, ovary, style, filament, petal, sepals

18
Q

Formation of Male gametophyte

A

Inside anther, Microsporangium contain microsporocyte (2n), meiosis, Microspores (n), Mitosis (each microspore), Pollen grain (One generative cell, mature pollen grains form)

19
Q

Formation of Female Gamtophyte

A

In Ovule, Megasporocyte (2n), meiosis, Megaspores (n-3 form, Mitosis, 8 megaspores, Seven cells, One with two nuclei, Five disapper, 1 becomes egg

20
Q

Mutualism

A

both side benefit

21
Q

Pollination

A

transfer of pollen grains from an another to a stigma

22
Q

Perfect (flowers)

A

Stamen and Carpels

23
Q

Imperfect (flowers)

A

Stamens OR Carpels

24
Q

Monoecious

A

Have both Stamen and Carpels on flower, but separate

25
Q

Dioecious

A

Stamen Or Carpel on different plants (Imperfect)
