25
Cross-pollination
Pollination of an ovule in flower with pollen from different individual plant
26
Parts of pistil
Stigma Style Ovary
27
Components of stamen
Anther | Filament
28
Produce and store pollen grains containing sperm nuclei
Anther
29
Supported by filaments
Anthers
30
Speed nucleus action
Travels down tube an fertilizes one egg
31
Dicotyledons + example
Two cotyledons surround embryo in each seed | Blueberry plants
32
Angiosperms
Fruit surround developing seeds | Fruit usually develops well around ovary
33
Offspring identical to parent
Asexual reproduction
34
Asexual benefits
No need to find a mate | Reproduction occurs rapidly
35
What duplicates in binary fission
Nucleus Organelles Cytoplasm plot into half
36
Plant and animal difference
Plants continue to grow through lives
37
Cuttings use
Used to produce clones
38
Hydra Sea sponges Yeast cells
Examples of budding
39
Mexican Whiptail
Asexual despite being a mammal Only has genetic info of mother Lays eggs
40
Sponge buds
May remain attached to parent resulting in colony
41
Hydras
Live in water | Small organisms
42
Most organism capable of
Both asexual and sexual
43
Bacterial conjugation note
Doesn’t result in reproduction | Only results in recombination
44
Antibiotic resistance is heritable/non-heritable
Heritable
45
Ferns and Moses reproduce by
Spores
46
Reproduce by forming seeds
Angiosperms and gymnosperms
47
Angiosperms
Flowering plants | Over half of plant species are
48
Gymnosperms
Produce seeds inside of cones | Conifers comes from cones
49
Ginkgo trees
Shed leaves in autumn Acc gymnosperms Last fo ancient group
50
Egg and sperm cell
Female and male gametes
51
Zygotes
First cell of growing organism | Contains genetic info from both parents
52
Pollen grains contain
Sperm nucleus
53
Zygote turn to
Multicellular embryo
54
Conditions needed for growth
Warmth Moisture Oxygen
55
Potatoes
Part of tuber Eyes of potato r acc buds of new plants Reproduce asexually by growing new shoots from underground stems
56
Tubers
Underground stems
57
Runners
Special stems from the main plant
58
Spider plant
Reproduces asexually | From runners that hang from main stem
59
Strawberries
Reproduce asexually | From runners that lie on ground
60
Lilacs
Spread by producing suckers
61
Suckers
Outgrowths of root or the lower part of stem
62
Life cycle of mosses
Alternation of generations During one portion asexual spores produced Later part egg and sperm cells produced
63
Mosses extra facts
Large numbers of sores produced Unfavourable temps and dry conditions Very light
64
Damp ground/spore
Spore can develop into moss then swim to egg cells or complete sexual stage or life cycle
65
Requirements for successful fertilization
``` Gametes must arrive in same place at same time Nutrients needed Moisture Sometimes warmth and protection Liquid environment ```
66
Gametes are (negative thing)
Delicate | Dry out quickly
67
Many aquatic organisms have fertilization which occurs … while land organisms have -||-
Outside of female | Within body of female
68
Negatives of external fertilization
Other organisms may eat gametes Water needed Water currents may sweep gametes away Extreme temps, pollutants, lack of O^2 destroy gametes Large numbers must be produced since most die
69
High rate of successful fertilization
Amongst mammals Conditions suitable Soren moves directly towards egg Mature egg cell needed
70
Opossum
Gives birth to offspring smaller than honeybee | Must remain in pouch for additional three months
71
Duck-billed platypus + echidna
Lonely mammals laying eggs Young do feed from mother’s milk Are protected
72
Gastropods
Snail and slugs | Most are hermaphrodites
73
Hermaphrodites
Each individual has both male and female reproductive organs Simultaneous hermaphroditism
74
Sequential hermaphroditism
Male when younger then female when older | Ensures they are large enough to produce and carry eggs
