Biology Study Checklist for AR2 – May 2025
-
Differences between sexual and asexual reproduction (PPT/Notes)
Examples of asexual reproduction: (PPT/notes)
Binary fission – in Bacteria
Budding in Yeast
Spore formation in Fungi
-
Sexual reproduction in plants
Structure of flower – labels, and function
Wind-pollinated and insect-pollinated flowers – adaptations
Pollination – self and cross-pollination – definitions
Fertilization of male nucleus in anther with female egg cell present in the ovule; seed
formation
Seed dispersal occurs by wind, water, animals, and explosion
Seed dispersal advantages: plants can colonize new areas; which reduces
competition for resources.
-
Sexual reproduction in Humans
Male reproductive system – labels and function (PPT)
Female reproductive system – Labels and function (PPT)
Definitions: Fertilization, ovulation, zygote, implantation
Antenatal care – Care during pregnancy (Unit 4.4 Pg. 160 – 164 coursebook)
-
Genes and inheritance (Unit 7 Coursebook)
Genes, chromosomes, DNA (Unit 7.1 – Pg. 224-246 + PPT)
Gametes – male (sperm cell), female (Egg cell) – structure and adaptations (Unit 7.2
248-252)
-
Variation (Unit 7.3 pg. 253- 258)
Definition causes – genetic and environmental, types of variation – continuous,
discontinuous
Species definition
Data collection, recording data (tally charts, constructing results tables), analyzing
data, making conclusions (AO3 skills)
-
Natural selection (Unit 7.4 – pg. 262 – 266)
Variation, competition, survival of the fittest, passing on successful characteristics
from one generation to the next, evolution
Antibiotic resistance as an example of natural selection.
-
Artificial selection (Selective breeding) – procedure. (PPT, Notes)
