|
Asexual reproduction |
Production of identical offspring from a single parent |
|
|
Sexual reproduction |
Production involving two gametes formed by the process of meiosis by 1 or more parent plant |
|
|
Pollination |
When the pollen (male gamete) is transferred to the stigma (female part) from the anther (male part) of the plant |
|
|
Wind pollinated flowers |
small, dull colours, no scent |
|
|
Insect pollinated flowers |
Bright large petals, nectar and fragrance |
|
|
Fertilisation |
The fusion of the male gamete and female gamete that produces and offspring such as a seed to then under go germination |
|
|
Germination factors |
Water, oxygen, warmth |
|
|
Warmth |
Enzymes require optimum temperature to function. This means the enzymes can break down starch to be used for respiration |
|
|
Respiration equation |
Glucose + oxygen = atp energy + h20 + co2 + heat |
|
|
Oxygen |
Required to activate enzymes in the seed needed for respiration |
|
|
Water |
Enters through micropyle and softens testa so the radicle can emerge to form the seed |
|
|
Warmth not at optimum temp |
Enzymes will decrease and then bonds holding the enzyme together will break and this causes the shape of the enzymes to change and the active site will no longer fit the substrate... Enzymes will not carry out biological function |
|
|
Testa |
Protects the seed from bacteria and insects... Softens when water comes through |
|
|
Cotyledon |
Stores food containing protein, fats and starches that provide energy for developing seeds |
|
|
Plumule |
Short bud |
|
|
Radicle |
Root |
|
|
Micropyle |
Small hole in testa for water absorption |
|
|
Germination |
Growth of a plant embryo after dormancy |
|
|
Photosynthesis |
Process whereby light energy from the sun will be converted into chemical energy in the form of sugar (glucose) |
|
|
Photosynthesis equation |
C02 + water ( chlorophyll + sunlight ) = glucose + oxygen |
|
|
Chloroplast |
Photosynthesis occurs in chloroplast where the chlorophyll absorb the Suns energy |
|
|
Vein |
Carry out water to all plants of leaf and collect and carry the food made in the leaf cells |
|
|
Leaf margin |
The outer edge of leaf so plants don't eat the leaf so that it can make photosynthesis |
|
|
Lamina ( leaf blade) |
The surface that is positioned to receive so lights. Thin to allow light to reach all cells within leaf |
|
|
Main rib |
Provides support to the leaf |
|
|
Incisors |
Chisel like teeth located at the front of the jaw |
|
|
Canines |
Pointed teeth to puncture and tear meet |
|
|
Molars |
Large flat surfaced teeth at the back of the jaw |
|
|
Carnivore teeth |
Canines- long and sharp to kill prey and tear meet Pointed incisors- to scrape meat off the bone Sharp Jagged molars - to cut through meat |
|
|
Herbivores teeth |
Large flat Molars - crushing and grinding of food Broad flat incisors - cutting plant material |
|
|
Diastema |
Herbivores have a diastema yo brake down chewed food as much as possible |
|
|
Saliva |
Contains an enzyme called amylase... Breaks down carbohydrates into complex sugars . Starch into glucose |
|
|
Peristalsis |
The movement used to pass a good bolus down the digestive system... Wave like contraction of muscles down the oesophagus |
|
|
Chemical digestion |
Breaks down enzymes into smaller molecules to increase surface area |
|
|
Structure of stomsch |
Muscular hollow sac/organ that contracts and relaxes to churn the good and physically digest it |
