Answers 100% Pass
What are the main functions of plant roots?
✔✔ To anchor the plant, absorb water and nutrients, and store food.
What is the role of the stem in plants?
✔✔ To support the plant, transport nutrients and water between roots and leaves, and store
nutrients.
What are the primary functions of plant leaves?
✔✔ To perform photosynthesis, exchange gases with the environment, and release water vapor.
What are the three main tissue types found in plants?
✔✔ Epidermal, vascular, and ground tissues.
What is the function of xylem tissue in plants?
✔✔ To transport water and dissolved minerals from the roots to other parts of the plant.
1
,What is the function of phloem tissue in plants?
✔✔ To transport the products of photosynthesis (mainly sugars) from the leaves to other parts of
the plant.
What are stomata and what is their function?
✔✔ Stomata are small openings on the surface of leaves that allow gas exchange (oxygen and
carbon dioxide) and water vapor to pass in and out of the plant.
What is the role of chloroplasts in plant cells?
✔✔ To conduct photosynthesis by converting light energy into chemical energy stored in
glucose.
What are the two main types of plant root systems?
✔✔ The fibrous root system and the taproot system.
What is the purpose of plant flowers?
✔✔ To facilitate reproduction by enabling the processes of pollination and fertilization.
2
, How do plants perform transpiration?
✔✔ By releasing water vapor through the stomata in their leaves, which helps to draw water up
from the roots.
What is the difference between monocots and dicots in terms of leaf venation?
✔✔ Monocots typically have parallel leaf venation, while dicots usually have a branching or net-
like pattern.
What are plant tissues that are involved in photosynthesis?
✔✔ The parenchyma cells in the mesophyll of the leaf.
What is the role of the plant cuticle?
✔✔ To provide a protective barrier against water loss and pathogens.
How do plant vascular tissues contribute to plant growth?
✔✔ By facilitating the transport of water, nutrients, and sugars throughout the plant, supporting
overall growth and health.
