All 18 flashcards from this kit, free and with no sign-up.
1. What are the three main morphological regions of a flowering plant?
Show the answer
Root system (underground), stem (above ground), and shoot system (stem + leaves + flowers).
2. Define the term 'root' in the context of flowering plants.
Show the answer
The root is the underground part of the plant that typically grows downward, absorbs water and minerals, and anchors the plant.
3. What is the difference between a taproot and a fibrous root system?
Show the answer
A taproot has one main root with smaller lateral roots (e.g., dicots), while a fibrous root system consists of many thin roots of similar size arising from the base of the stem (e.g., monocots).
4. Name the region of the root that is responsible for cell division and growth.
Show the answer
The root apical meristem, located at the tip of the root, is responsible for cell division and growth.
5. What is the function of root hairs?
Show the answer
Root hairs increase the surface area for absorption of water and minerals from the soil.
6. Define a 'node' and an 'internode' on a stem.
Show the answer
A node is the point on a stem where leaves or buds arise; an internode is the region between two consecutive nodes.
7. What are the two main types of buds found on a stem?
Show the answer
Terminal (apical) bud at the tip and axillary (lateral) buds in the axils of leaves.
8. What is the function of the stem in a flowering plant?
Show the answer
The stem provides support to leaves and flowers, conducts water and nutrients, and sometimes stores food.
9. What is a 'phyllotaxy'?
Show the answer
Phyllotaxy is the arrangement of leaves on a stem or branch.
10. Name the three main types of leaf arrangements (phyllotaxy).
Show the answer
Alternate (one leaf per node), opposite (two leaves per node), and whorled (three or more leaves per node).
11. What is the difference between a simple leaf and a compound leaf?
Show the answer
A simple leaf has a single, undivided blade, while a compound leaf has a blade divided into multiple leaflets.
12. What is the function of the leaf in a flowering plant?
Show the answer
The leaf is the primary site of photosynthesis, gas exchange, and transpiration.
13. What are the parts of a typical flower?
Show the answer
Calyx (sepals), corolla (petals), androecium (stamens), and gynoecium (pistil/carpels).
14. What is the function of the calyx and corolla in a flower?
Show the answer
The calyx (sepals) protects the flower bud, and the corolla (petals) attracts pollinators.
15. What is the androecium?
Show the answer
The androecium is the male reproductive part of a flower, consisting of stamens (each with an anther and filament).
16. What is the gynoecium?
Show the answer
The gynoecium is the female reproductive part of a flower, consisting of one or more carpels (each with stigma, style, and ovary).
17. What is the difference between a unisexual and a bisexual flower?
Show the answer
A unisexual flower has either stamens or carpels but not both, while a bisexual flower has both stamens and carpels.
18. What is the function of the ovary in a flower?
Show the answer
The ovary contains ovules, which develop into seeds after fertilization; the ovary itself matures into a fruit.
