Worked Solution & Example Answer:Draw a diagram of a plant - Leaving Cert Biology - Question c - 2015
Step 1
Draw a diagram of a plant. Label the root, stem and leaf on the diagram.
Answer
To adequately showcase the structure of a plant, draw a vertical representation with a clear root system at the bottom, a stem in the middle, and leaves extending from the stem. Ensure each part is distinctly labeled:
- Root
- Stem
- Leaf This will provide a visual reference for understanding the roles of each component.
Step 2
Where in a plant does photosynthesis usually occur?
Answer
Photosynthesis primarily occurs in the leaves of a plant. The presence of chlorophyll in the chloroplasts of leaf cells allows the absorption of sunlight, which is essential for converting carbon dioxide and water into glucose and oxygen.
Step 3
Give two functions of the root.
Answer
The roots serve multiple roles in a plant, including:
- Anchoring the plant securely in the soil, providing stability against environmental forces.
- Absorbing water and essential nutrients from the soil, which are vital for the plant's growth and metabolic processes.
Step 4
Plants contain vascular tissue. Explain the term vascular.
Answer
The term vascular refers to tissues in plants that are specialized for the transport of water, nutrients, and food throughout the organism. Vascular tissues consist mainly of xylem, responsible for water and nutrient transport, and phloem, which distributes the sugars produced during photosynthesis.
Step 5
Step 6
Explain the term meristem and give one location in a plant where meristematic tissue can be found.
Answer
Meristem refers to the regions of undifferentiated plant cells that are capable of division and growth. These cells play a crucial role in the growth of new tissues. One location where meristematic tissue can be found is at the tip of the shoot or the tip of the root, where it facilitates growth in length.
