Plant & Cell Respiration Revision Flashcards
This deck includes biology work done in the end of term 1 and in term 2 about plants. This covers respiration within plants and cells , photosynthesis, plant tissues, structures and processes, transportation and gas exchange.
What is an autotroph?
An autotrophs are organisms that make their own food and don’t need to consume it. Usually autotrophs make their own food via photosynthesis.
What is a heterotroph?
A heterotroph are organisms that consume food through other means, like eating meat, plants, etc.
What is a producer?
A producer is in the food chain and it means that it is food for other consumers and is near the bottom.
What is a consumer?
A consumer is in the food chain and it consumes things, meaning it can consume plants or it can consume animals, basically anything.
Order of food chain?
Producer - primary consumer - secondary consumer - tertiary consumer - final consumer - decomposer (fungi)
What organisms are autotrophs?
Plants, algae, and some bacteria
What organisms are heterotrophs?
Essentially anything that eats through its mouth, like humans, animals.
Input and output of photosynthesis?
Sunlight + water + carbon dioxide = oxygen + sugar
Input and output of cellular respiration?
Oxygen + sugar = water + carbon dioxide + ATP (energy)
What are the two plant transport vessels?
Xylem and phloem
What is the xylem for?
The xylem transports water and dissolved minerals from the roots, up through the plant and eventually out through the leaf stomata.
What direction does the contents in xylem go?
The water and minerals move from the roots to the stem then to the leaves (only moves up).
What is the phloem for?
The phloem is the vessel that transports food materials (mainly sucrose and amino acids). made by the plant from photosynthesising
What direction does the contents in xylem go?
The food materials (sucrose and amino acids) made by the plant from photosynthesising goes to non photosynthesising regions in the root and stem.
Where are the phloem and xylem arranged?
The phloem and xylem are arranged throughout the root, stem and leaves.
