Answers are for parents and teachers.
1
Compare gymnosperms and angiosperms in a table by 4 features.
Flower: no/yes; ovule: on scale/in ovary; fruit: no/yes; double fertilization: no/yes.
2
Give 5 examples each of monocot and dicot plants.
Monocots: wheat, maize, rice, onion, tulip. Dicots: apple, bean, cotton, cabbage, rose.
3
Draw a comparison of a juniper and a pine (or other conifer) twig.
Juniper: small scale/needle leaves, fleshy cone; pine: paired needles, woody cone.
4
A juniper cone ripens 2–3 years after fertilization. If fertilization was in 2020, in which year is the earliest ripening? (2020 + 2)
2022
5
Why did angiosperms come to dominate the plant world?
Seeds are protected in fruits and spread easily; they have double fertilization and efficient vessels.
