What part of the Earth is called the ‘Lungs of the Earth’, and what actually produces the most oxygen?
The Amazon Rainforest. It produces roughly 5%, but marine plants produce around 75% of the Earth’s oxygen.
What is needed for photosynthesis to happen?
Water, Light Energy, Chlorophyll and Carbon Dioxide.
Where is Chlorophyll typically found?
In a plant’s Chloroplasts.
Why do leaves change colour in the fall?
The chloroplasts begin to break down due to a lack of sunlight, decreasing photosynthesis production and allow for other chemicals to colour the leaves. (I SEE YOUR TRUE COLOURS SHINING THROUGHHHHHH)
What is Step One of Photosynthesis?
The Breaking Down of Water Molecules and Carbon DIoxide. Light Energy is needed to split the water molecules and the Carbon Dioxide molecules into oxygen, carbon and hydrogen molecules.
What’s Step Two of Phototsynthesis?
Combine Hydrogen, Carbon and Oxygen atoms into Glucose (C6, H12, O6) Glucose is essential for plants, and the extra atoms combine into Oxygen (O2) as a byproduct.
What is Respiration? (Not the Minecraft one)
It is the process organisms use to use the energy from glucose, or sugars.
What is needed for Respiration to work?
Oxygen; it breaks down the sugars.
What do the organism’s cells receive? (respiration process’ products)
Adenosine Triphosphate (energy) and water and carbon dioxide as a byproduct.
How do bees tell other bees where flowers are
a series ‘waggle dances’ that determine direction and distance.
What’s the purpose of flowers?
To attract pollinators to, well, pollinate the plant.
What in particular attracts pollinators?
Petals and Sepals, especially brightly coloured ones.
What are the ‘male’ parts of the flower?
the Stamen, including the: - Anther - Filament It provides the pollen.
What is the Anther and what does it do?
The Anther is part of the Stamen and it holds the plant’s pollen.
What is the Filament and what does it do?
Also part of the Stamen, the Filaments’ job is to hold the Anther higher up to the pollinators can come in contact with it.
What is the ‘female’ part of the flower?
The ‘Pistil’, or the Carpel is the female part of the flower that catches pollen from other plants. It’s made of: - the Stigma - the Style - & the Ovary
What is the Stigma and what does it do?
The Stigma is at the top of the Pistil, and catches pollen.
What is the Style and what does it do?
The Style allows the pollen to reach the eggs.
What is the Ovary and what does it do?
The Ovary contains Ovules, which contain eggs that’ll become seeds.
What are the Non-Insect forms of pollination?
• WInd Blown Pollination (allows pollen to be distributed via the air) i.e. Grasses and Ragweed • Self- Pollination i.e. Orchids
Which country (arguably) has the largest number of Carnivorous Plants?
Australia, followed by Brazil.
What are Carnivorous Plants?
They’re plants that gain sustenance attracting, trapping and digesting animals.
Where do Carnivorous Plants live?
They typically live in nutrient-poor soil conditions, so they need more nutrients.
What are the ways that a Carnivorous Plants can get food?
• Pitfall • Adhesives • Snap Trap • Suction
