Question 2

Definition of:
Sexual reproduction

Answer 2

A form of reproduction where there’s two parents involved

Question 3

Definition of:
Binary fission (in asexual reproduction)

Answer 3

A form of asexual reproduction where one cell splits into two identical offspring

Question 4

Definition of:
Spores (in asexual reproduction)

Answer 4

Millions of tiny “seeds” are dispersed into the air, some will find good soil to grow in and start developing

Question 5

Definition of:
Budding (in asexual reproduction)

Answer 5

Parent produces a small, identical offspring attached to itself, the offspring can stay connected or detached

Question 6

Definition of:
Vegetative Reproduction (in asexual reproduction)

Answer 6

Consist of:
- Runners
> stems that grow horizontally from the plant that spread to grow more of the plant
- Tubers
> root-like structures that can be used for asexual reproduction

Question 7

Answer 9

eggs (ovum)

Question 10

Definition of:
Fertilization

Answer 10

The union of two gametes, one male, one female

Question 11

“Female” parts of a plant

Answer 11

• Stigma
• Style
• Ovary
• Ovule

Question 12

“Male” parts of a plant

Answer 12

• Pollen
• Anther
• filament

Question 13

Process of plant growth + reproduction

Answer 13

• Germination
  > seed becomes plant
• Growth
  > structure developed
• Pollination
  > pollen is carried to male part of plant

Question 14

Where can male gametes be found in a plant

Answer 14

In pollen, which is stored in the stamen

Question 15

Definition of:
Zygote

Answer 15

The cell created when two gametes join (in sexual reproduction)

Question 16

Definition of:
Mitosis

Answer 16

Cell division,
The original zygote splits into multiple cells, and the process continues.

Question 17

Advantages of Asexual reproduction

Answer 17

• Produces offspring at a much faster rate than sexual reproduction
• Only needs one parent

Question 18

Disadvantages of Asexual reproduction

Answer 18

• No diversity
  > If something new crosses their path, say a new disease, the entire population could be wiped out

Question 19

Advantages for Sexual reproduction

Answer 19

• In some cases, only the strongest can reproduce and pass their traits down to the next generation
• Offers protection for growing embryos

Question 20

Definition of:
Bacterial conjugation

Answer 20

One bacteria transfers its bacteria to the other

Internal Fertilization

Answer 22

Occurs when organisms fertilize their eggs inside of the females parents womb

Question 23

Answer 23

When the pollen from another plant is transferred to the stigma

Question 24

Definition of:
Cross pollination

Answer 24

When the pollen from one plant is carried to another plant
