Blooming and Boomless: The Life Cycles of Flowering and Non-Flowering Plants
Imagine a vibrant garden, blooming with roses and daisies and lush with ferns and mosses. These plants, flowering and non-flowering, each have unique life cycles. Flowering plants start as seeds, sprouting into seedlings, then growing into mature plants. They then produce flowers, which, after pollination, bear seeds inside fruits, restarting the cycle. Non-flowering plants, like ferns, have an interesting life story too. They start as spores, which grow into a structure called a gametophyte. The gametophyte then produces eggs and sperms. After fertilization, a new sporophyte grows, eventually producing spores again. These cycles play a crucial role in maintaining our planet's biodiversity. Next time you're in a garden, see if you can spot these miraculous processes unfolding!
Question 1
What starts the life cycle of a flowering plant?
Seed
Explanation. The life cycle of a flowering plant begins with a seed, which sprouts into a seedling and then grows into a mature plant.
Flower
Fruit
Spore
Leaf
Question 2
What happens after the flowers of a flowering plant are pollinated?
They produce leaves
They produce fruits with seeds inside
Explanation. After pollination, flowers of flowering plants produce fruits. Inside these fruits are seeds, which can sprout into new plants, restarting the life cycle.
They produce spores
They start growing into a new plant
Question 3
What is the term for the process through which flowering plants produce seeds?
Fertilization
Pollination
Explanation. Pollination is the process through which flowering plants produce seeds, typically within fruits.
Germination
Photosynthesis
Respiration
Question 4
What is produced by the gametophyte of non-flowering plants?
Seeds
Spores
Fruits
Eggs and Sperms
Explanation. The gametophyte of a non-flowering plant produces eggs and sperms. After fertilization, a new sporophyte grows, which eventually produces spores.
Flowers
Question 5
What role do these life cycles play for our planet?
They make gardens vibrant
They provide food for animals
They maintain biodiversity
Explanation. The life cycles of plants, both flowering and non-flowering, play a crucial role in maintaining our planet's biodiversity.
They produce oxygen
They provide shade
