L1 Flashcards
What are the four main organs of the plant?
The root, the stem, the leaves and the flowers.
What is the function of the root?
This offers stability and support for the plants to grow very tall. They are also responsible for absorbing water and minerals from the soil.
What is the function of the stem?
This supports the leaves. It also has a xylem which transports water from the soil up to the plant and even provides storage and support. It even has a phloem which carries nutrients through the plant.
What is the function of the leaf?
This transports water to the cells of photosynthesis (the chloroplasts). They use light energy, they react carbon dioxide and water to make food (glucose) and oxygen.
What is the function of the flower?
These are the plant’s reproductive organs. They are responsible for fertilisation and pollination.
What does the plant cell consist of?
The nucleus, the chloroplasts, cytoplasm, vacuole, the cell wall, the cell membrane, mitochondria and ribosomes.
What is the function of the nucleus?
The nucleus controls the cell, it is essentially the brain of the cell.
What is the function of the chloroplasts?
These are green discs which are responsible for photosynthesis.
What is the function of cytoplasm?
It is a fluid where all the events of the cell happens.
What is the function of the vacuole?
This maintains water balance in the cell.
What is the function of the cell wall?
This is made out of cellulose and it is a strong structure, keeping the plant cell inflexible.
What is the function of the cell membrane?
This regulates the transport of materials exiting and entering the plant cell, such as oxygen and carbon dioxide.
What is the function of mitochondria?
This produces energy through cellular respiration/using oxygen to make energy from carbohydrates (sugars).
What is the function of ribosomes?
These are responsible for protein synthesis (producing protein for the plant cell). It does this by using the DNA of plants (mRNA) that are already inside of the mitochondria, chloroplasts and plastids and then transcribe their genetic code into protein.
