Pollination and plant life cycles - One Line Questions

1. The female reproductive part of a flower, consisting of stigma, style, and ovary, is called the: — Gynoecium
2. The dispersal of seeds by animals is known as: — Zoochory
3. The dispersal of seeds by water is termed: — Hydrochory
4. The process where pollen grains are transferred from the anther to the stigma by water is called: — Hydrophily
5. Which part of the flower is responsible for producing nectar to attract insects? — Nectary
6. Cross-pollination, where pollen is transferred between flowers of different plants of the same species, is also called: — Xenogamy
7. Flowers pollinated by wind typically have: — Small, lightweight pollen and lack of scent
8. The collective term for all the petals of a flower is: — Corolla

10. The collective term for all the sepals of a flower is: — Calyx
11. The first leaf or leaves that emerge from a germinating seed are called: — Cotyledons
12. Self-pollination occurs when pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant. This is also known as: — Geitonogamy
13. What is the process called when a flower is pollinated by pollen from the same flower? — Autogamy
14. What environmental conditions are typically required for seed germination? — Warmth, water, and oxygen
15. A seed that has only one cotyledon is characteristic of: — Monocotyledonous plants
16. A plant that has separate male and female flowers on the same individual plant is called: — Monoecious
17. In many dicotyledonous plants, the cotyledons (seed leaves) often emerge above ground and turn green, performing photosynthesis. This is called: — Epigeal germination
18. In some plants, like peas and oaks, the cotyledons remain below the ground during germination and do not photosynthesize. This is known as: — Hypogeal germination
19. What is the process by which pollen is transferred from the anther to the stigma called? — Pollination
20. What is the term for the process where a pollen grain germinates on the stigma and grows a pollen tube down to the ovary? — Fertilization
21. The part of the stamen that produces pollen is the: — Anther
22. The stalk that connects the stigma to the ovary is the: — Style
23. After fertilization, the ovule develops into a: — Seed
24. What is the part of the plant that contains the embryo and stored food, enclosed within a protective coat? — Seed
25. The male reproductive part of a flower, consisting of the anther and filament, is called the: — Androecium
26. Which of the following is a characteristic of insect-pollinated flowers? — Sticky or spiny pollen
27. A seed with two cotyledons is characteristic of: — Dicotyledonous plants
28. What term describes a plant species that has male and female reproductive organs on separate individuals? — Dioecious
29. Which part of the flower develops into a fruit? — Ovary
30. What is the term for the development of a fruit without fertilization? — Parthenocarpy
31. Which part of the flower typically protects the bud before it opens? — Sepals
32. What is the structure within the ovary that contains the female gamete? — Both B and C
33. The fusion of the male gamete (from the pollen) with the female gamete (egg cell) inside the ovule is called: — Fertilization
34. The process by which a seed sprouts and begins to grow into a new plant is called: — Germination
35. When the stigma of a flower is receptive before the anthers mature and release pollen, the condition is known as: — Protogyny
36. The phenomenon where flowers mature at different times to prevent self-pollination is known as: — All of the above
37. If a flower's anthers mature and release pollen before its stigma becomes receptive, this condition is called: — Protandry
38. The plumule is the part of the embryo that develops into the: — Shoot system (stem and leaves)
39. The ovary of the flower typically develops into the: — Fruit
40. Bats are known to pollinate certain plants, especially those that bloom at night and have: — Large, pale or white flowers with strong, fruity or musky odors
41. Which part of the flower contains the pollen? — Anther
42. What is the term for the stalk that supports the anther? — Filament
43. The receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower is known as the: — Stigma
44. What is the primary function of the radicle during germination? — To anchor the seedling and absorb water
45. What is the primary function of a flower's petals? — To attract pollinators
46. What is the process by which a plant produces a new individual from a seed? — Sexual reproduction
47. Birds are common pollinators for flowers that are often: — Red or orange and produce abundant nectar
48. Which of the following is NOT a method of pollination? — Fungal pollination (Mycophily)
49. The process of seed dispersal by wind is called: — Anemochory
