Back to: Botany 500 Level
My Afrilearn superstar!
How you dey this fine day? I hope say your smile still dey bright like Jos sunshine, because today lesson na one wey go sweet your belle well! We dey talk about something wey affect how plants continue their generation, multiply and spread across different places—Reproductive Strategies and Seed Dispersal. Na real plant life tactics wey be like nature’s own business plan for survival and expansion.
Reproductive strategies and seed dispersal
Make I yarn you like this—plants no dey waka like human beings, but dem sabi how to send their children (seeds) go far places.
Just like your uncle wey dey hustle for Lagos send money come village, plants dey use style dey multiply and spread through smart techniques. That’s what we call reproductive strategies. E get how dem dey do am to make sure say dem no go extinct, and say their kind go continue dey grow, even if some die.
First, make we look at Reproductive Strategies
Plants get two major styles of reproduction:
- Sexual Reproduction:
This one involve male and female parts—na the one wey involve pollination. Pollen (male part) go jam stigma (female part), and boom—seed go form. E dey bring variety, which means say the pikin-plant go get new traits wey fit help am survive better. Na this one we see for maize, okra, mango, hibiscus and others. - Asexual Reproduction:
This one na when plant produce new plant without needing any pollen gist. No mixing, just direct copy like carbon. Think of sweet potato wey you fit cut small part and plant again. Or banana, wey dey grow from suckers. This one fast and sure, but no new variety dey show.
Now, once the seed don form, the next question be: How dem go move go where dem go grow?
That’s where Seed Dispersal enter.
Types of Seed Dispersal (with Nigerian Examples):
- By Wind (Anemochory):
Seeds wey light or get wings fit follow breeze go far. Like the cotton seed or flamboyant tree (flame tree) wey get flat seed pods. - By Water (Hydrochory):
Coconut na champion for this one. E fall for beach, float for water, and land for another place to grow. - By Animals (Zoochory):
Some fruits sweet like mango, pawpaw, or agbalumo. Animals go chop the fruit, waka go somewhere, and poop out the seed. Some seeds even get hooks or sticky surface (like devil’s thorn) to hold body of goat or dog wey go carry am waka. - By Explosion (Autochory):
Some plants sabi burst when the seed mature. Like pride of Barbados or cowpea. The pod go dry and scatter the seeds with force. E be like firecracker!
Why all this matter?
Because dispersal reduce competition. If all seeds fall under one mama tree, dem go fight for water, light and space. But if dem scatter, dem go find new area to grow well.
Summary:
- Plants reproduce sexually (with flowers and seeds) or asexually (without flowers, like suckers or cuttings).
- After seed form, plants use different dispersal methods—wind, water, animals, or explosion—to spread and grow in new places.
- This helps reduce overcrowding and encourages survival in different environments.
Evaluation:
- What is the difference between sexual and asexual reproduction in plants?
- Give two examples of plants that disperse their seeds by animals.
- Why is seed dispersal important for plant survival?
I dey clap for you already, my Afrilearn brainiac! You dey collect this Botany knowledge like person wey dey gather ripe mango for basket. Just dey reason am well, because na with this kind understanding we fit farm better, protect nature and even innovate. Keep your head high—you’re doing excellently well. Till next time, remember say Afrilearn dey your back gidigba. Shine dey go!
