D3.1 Reproduction SL

Question 1

Asexual Reproduction

Answer 1

Reproduction involving one parent, resulting in genetically identical offspring (e.g., budding in potatoes)

Question 2

Sexual Reproduction

Answer 2

Requires two parents; offspring are similar but not genetically identical to parents

Question 3

Meiosis

Answer 3

A process creating genetic variation in sexually reproducing organisms

Question 4

Clone

Answer 4

An offspring genetically identical to its parent, common in asexual reproduction

Question 5

Genetic Diversity

Answer 5

Sexual reproduction results in genetic variation, which is crucial for adaptation to environmental changes

Question 6

Sperm

Answer 6

Male gamete, smaller, motile, produced in large numbers by testes

Question 7

Ovum (Egg)

Answer 7

Female gamete, larger, non-motile, contains food reserves, produced in smaller numbers by ovaries

Question 8

Testes

Answer 8

Male reproductive organs producing sperm

Question 9

Ovaries

Answer 9

Female reproductive organs producing eggs

Question 10

Gamete

Answer 10

A sex cell (sperm or egg) produced by meiosis, involved in sexual reproduction

Question 11

Menstrual Cycle

Answer 11

Monthly cycle preparing the female body for pregnancy, regulated by hormones

Question 12

Ovulation

Answer 12

Release of a mature egg from the ovary

Question 13

Follicular Phase

Answer 13

Phase in the menstrual cycle where ovarian follicles mature

Question 14

Luteal Phase

Answer 14

Post-ovulation phase where the corpus luteum forms and secretes hormones

Question 15

FSH and LH

Answer 15

Pituitary hormones that regulate the menstrual cycle

Question 16

Stamen

Answer 16

Male reproductive part of a flower, produces pollen

Question 17

Pistil/Carpel

Answer 17

Female reproductive part of a flower, contains the ovules

Question 18

Pollination

Answer 18

Transfer of pollen from stamen to pistil

Question 19

Fertilisation in Plants

Answer 19

Fusion of male and female gametes in plants, forming a diploid zygote

Question 20

Double Fertilisation

Answer 20

Unique to flowering plants, involves the fusion of two sperm cells with different parts of the ovule

Question 21

Cross-Pollination

Answer 21

Transfer of pollen between different plants, increases genetic diversity

Question 22

Self-Pollination

Answer 22

Transfer of pollen within the same plant, less genetic diversity

Question 23

Self-Incompatibility

Answer 23

Mechanism preventing self-fertilisation in plants, promotes genetic diversity

Question 24

Seed Dispersal

Answer 24

Spreading of seeds away from the parent plant, reduces competition

Question 25

Germination

Answer 25

Process where a seed develops into a new plant under favorable conditions
