Question
The grass in this photo is a flowering plant and therefore is
a moss / a fern / a gymnosperm /an angiosperm. (Circle one)
2. This flowering plant is a monocot / dicot. (Circle one)
3. This green moss plant is the sporophyte / gametophyte. (Circle one)
4. These structures sticking out of the moss plant produce _______________ through meiosis.
5. The gymnosperm plants and structures in these photos are the sporophyte / gametophyte. (Circle one)
6. This is a moss / a fern / a gymnosperm / an angiosperm. (Circle one)
7. This plant produces spores in the brown structures on the underside of the fronds through the
process of mitosis / meiosis. Circle one)
8. The gametophyte of the fern shown here produces gametes through the process of
mitosis / meiosis. Circle one)
9. The flower labeled B is a monocot / dicot (Circle one.)
14. Bracket A is a cross section of what flower structure?___________________________
15. This anther produces the male gametophyte, also known as the ______________________.
16 and 17. These pollen grains contain two nuclei – the generative nucleus will become the
____________________, and the __________________________________ nucleus will cause
the pollen tube to form.
19. Flowers produce ovules in the flower part known as the _______________
20. The seeds of this small pumpkin developed from the _______________ after the egg was fertilized.
The following questions do not refer to a photo:
21. The gametophyte of a plant is haploid / diploid / triploid (Circle one.)
22. The megaspore mother cell in the ovule divides by meiosis and produces a haploid spore, which then divides by mitosis and produces one egg nucleus and two polar nuclei. The egg is fertilized by a sperm - that becomes the __________________________ and is ___ploid. The two polar nuclei are fertilized by a sperm – that becomes the ____________________ which is ___ploid.
23. The endosperm provides ___________ to the embryo.
24. Circle all from the following list that produce multicellular dependent embryos.
moss / fern / gymnosperm / angiosperm
25. Circle all from the following list that produce seeds.
moss / fern / gymnosperm / angiosperm
Explanation / Answer
Angiosperm- all flowering plants come under this category Monocot- it has only one cotelydon in its seed eg-rice, maize etc Sporophyte- mosses doesn't produce seeds. It produces spores...And after fertilization develops sporophytes which contains spores Spores. Spores are produced by the sporophytes. Sporangia store the spores
