2x
29
Gymnosperm
“Naked seed” | Ex. Picea
30
Angiosperm
“Enclosed seeds” | Ex. Lilium
31
Parts of ovule (seed)
Female gametophyte Megasporangium Integuments (2 layers) Micropyle (top)
32
Female flower part
Pistil: (made of carpels) Stigma Style Ovary
33
Male flower part
Stamen: Anther Filament
34
Petals
Colorful
35
Sepals
Green (protect)
36
Receptacle
Inside around ovule
37
Funiculus
Short wide stalk of ovule in ovary
38
Locule
Internal chamber (ovule inside) of ovary
39
Placenta
Central tissue of pistil
40
4 types of leaves
Petals (colourful/attract) Sepals (green enclosed) Stamens (male, pollen-producing anther of 4 microsporangia) Carpels (female, fused=pistil, stigma, style, ovary houses ovule)
41
Porifera cell walls
Spongin (fibrous protein) and spicules (calcium carbonate or silica)
42
Spongocoel
Internal cavity lined with flagellated cells
43
Osculum
Spongocoel opening releases water and waste = filter feeding
44
Mesoglea
Holds together epidermis and gastrodermis
45
Cnidoblasts
Contain microscopic nematocysts with venomous harpoons for immobilizing prey and defense
46
Auricles and eyespots
Auricles: sensitive to touch/chemical signals Eyespots: sensitive to light
47
Pharynx
Muscular tube of Dugesia that searches for food
48
Muscular pharynx
Force to propel food through gut in Turbatrix
49
Pseudocoelom
Gap between endoderm and mesoderm that stores fat droplets
50
Hermaphrodites
Produces male and female gametes | Ex. Grantia(sponge) Dugesia(flatworm) Lumbricus(earthworm)
51
Cuticle
Protective outer layer of Lumbricus, must be kept moist (respire through skin)
52
Clitellum
Thickened region of Lumbricus covers 6 segments (involved in sexual reproduction) secretes thick mucus to attach worms exchanging sperm
53
Segmentation
Important for Lumbricus locomotion (circular and longitudinal muscles inversely contract/relax)
54
5 hearts
Pump blood into ventral blood vessel of Lumbricus
55
Lumbricus layers
``` Epidermis Circular muscle (outer mesoderm) Longitudinal muscle (outer mesoderm) Coelom Inner mesoderm endoderm ```
56
Mollusca
Soft bodies | Gills and lungs
57
Mollusca 3 parts
1. Foot: locomotion muscular contractions 2. Visceral mass: contains internal organs 3. Mantle: fold of tissue which secretes the shell
58
Tongue-like radula
Bear many teeth, used to eat plants and scrape food off rocks (Mollusca)
59
Chelipeds
Bear large pincers Defender Subdue prey Sexual display
60
Mouthparts
Maxillipeds, maxillae: break food | mandibles: cut/grind food
61
Walking legs
Attached to cephalothorax Locomotion Pincers on 2 anterior pairs for food
62
Feathery gills
- Attached to basal segments | - Walking legs move water over gills for oxygen
63
Pleopods
(Swimming legs) Create water current over gills x3 pairs male x5 pairs female
64
Gonopods
x2 pairs male | Transfer sperm to female seminal receptacle
65
Tail fan
Propels animal Telson- middle Uropods- sides
