Plant Systems

1. The process in living organisms where they release energy from food, typically using oxygen.
3. Tiny structures in cells that act like powerhouses, providing energy for the cell's activities.
6. The process of taking in oxygen and releasing carbon dioxide, essential for respiration in animals and photosynthesis in plants.
8. The top part of the female reproductive structure in a flower, where pollen is received for fertilisation.
9. The part of a flower that produces pollen, containing male reproductive cells.
10. A part of plant cells that contains chlorophyll, allowing them to capture sunlight and carry out photosynthesis.
12. A group of plants that produce flowers and seeds enclosed in fruits.
13. A group of plants that bear "naked" seeds, often found on cones or similar structures.
15. The central part of a plant that supports leaves and flowers and transports water and nutrients.
16. The underground part of a plant that anchors it, absorbs water and nutrients, and stores food.
17. A plant tissue that transports food (sugars) produced in the leaves to other parts of the plant.
18. Small pores on the surface of plant leaves that regulate the exchange of gases, like carbon dioxide and oxygen.

2. The release of water vapour from plant leaves through tiny openings called stomata.
4. The interconnected network of xylem and phloem that helps distribute water, nutrients, and food throughout a plant.
5. A type of non-flowering plant with feathery leaves that reproduces using spores.
7. A characteristic or behaviour that helps an organism survive and thrive in its environment.
8. A tiny reproductive cell that can develop into a new organism, often seen in fungi and some plants.
11. A plant tissue that transports water and nutrients from the roots to the rest of the plant.
14. The process by which plants use sunlight to convert carbon dioxide and water into food (glucose) and oxygen.
16. The process of creating new individuals of a species, ensuring their survival and continuation.
